The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A modulatory role for clathrin light chain phosphorylation in Golgi membrane protein localization during vegetative growth and during the mating response of Saccharomyces cerevisiae. (1/1739)

The role of clathrin light chain phosphorylation in regulating clathrin function has been examined in Saccharomyces cerevisiae. The phosphorylation state of yeast clathrin light chain (Clc1p) in vivo was monitored by [32P]phosphate labeling and immunoprecipitation. Clc1p was phosphorylated in growing cells and also hyperphosphorylated upon activation of the mating response signal transduction pathway. Mating pheromone-stimulated hyperphosphorylation of Clc1p was dependent on the mating response signal transduction pathway MAP kinase Fus3p. Both basal and stimulated phosphorylation occurred exclusively on serines. Mutagenesis of Clc1p was used to map major phosphorylation sites to serines 52 and 112, but conversion of all 14 serines in Clc1p to alanines [S(all)A] was necessary to eliminate phosphorylation. Cells expressing the S(all)A mutant Clc1p displayed no defects in Clc1p binding to clathrin heavy chain, clathrin trimer stability, sorting of a soluble vacuolar protein, or receptor-mediated endocytosis of mating pheromone. However, the trans-Golgi network membrane protein Kex2p was not optimally localized in mutant cells. Furthermore, pheromone treatment exacerbated the Kex2p localization defect and caused a corresponding defect in Kex2p-mediated maturation of the alpha-factor precursor. The results reveal a novel requirement for clathrin during the mating response and suggest that phosphorylation of the light chain subunit modulates the activity of clathrin at the trans-Golgi network.  (+info)

Blind smell: brain activation induced by an undetected air-borne chemical. (2/1739)

EEG and behavioural evidence suggests that air-borne chemicals can affect the nervous system without being consciously detected. EEG and behaviour, however, do not specify which brain structures are involved in chemical sensing that occurs below a threshold of conscious detection. Here we used functional MRI to localize brain activation induced by high and low concentrations of the air-borne compound oestra-1,3,5(10),16-tetraen-3yl acetate. Following presentations of both concentrations, eight of eight subjects reported verbally that they could not detect any odour (P = 0.004). Forced choice detection performed during the presentations revealed above-chance detection of the high concentration, but no better than chance detection of the low concentration compound. Both concentrations induced significant brain activation, primarily in the anterior medial thalamus and inferior frontal gyrus. Activation in the inferior frontal gyrus during the high concentration condition was significantly greater in the right than in the left hemisphere (P = 0.03). A trend towards greater thalamic activation was observed for the high concentration than the low concentration compound (P = 0.08). These findings localize human brain activation that was induced by an undetectable air-borne chemical (the low concentration compound).  (+info)

Central processing of pulsed pheromone signals by antennal lobe neurons in the male moth Agrotis segetum. (3/1739)

Male moths use female-produced pheromones as orientation cues during the mate-finding process. In addition to the needs of evaluating the quality and quantity of the pheromone signal, the male moth also needs to resolve the filamentous structure of the pheromone plume to proceed toward the releasing point successfully. To understand how a discontinuous olfactory signal is processed at the central level, we used intracellular recording methods to characterize the response patterns of antennal lobe (AL) neurons to pulsatile stimulation with the full female-produced pheromone blend and its single components in male turnip moths, Agrotis segetum. Air puffs delivered at frequencies of 1, 3, 5, 7, or 10 Hz were used to carry the stimulus. Two types of AL neurons were characterized according to their capabilities to resolve stimulus pulses. The most common type could resolve at least 1-Hz pulses, thus termed fast neurons; another type could not resolve any pulses, thus termed slow neurons. When fast neurons were excited by stimuli, they always displayed biphasic response patterns, a depolarization phase followed by a hyperpolarization phase. This pattern could be evoked by stimulation with both the single pheromone components and the blend. The pulse-resolving capability of the fast neurons correlated significantly with the size of the hyperpolarization phase. When the amplitude was higher and the fall time of the hyperpolarization faster, the neuron could follow more pulses per second. Moreover, interactions between different pheromone components eliciting different response patterns did not improve the pulse-resolving capability of fast neurons.  (+info)

A Cdc24p-Far1p-Gbetagamma protein complex required for yeast orientation during mating. (4/1739)

Oriented cell growth requires the specification of a site for polarized growth and subsequent orientation of the cytoskeleton towards this site. During mating, haploid Saccharomyces cerevisiae cells orient their growth in response to a pheromone gradient overriding an internal landmark for polarized growth, the bud site. This response requires Cdc24p, Far1p, and a heterotrimeric G-protein. Here we show that a two- hybrid interaction between Cdc24p and Gbeta requires Far1p but not pheromone-dependent MAP-kinase signaling, indicating Far1p has a role in regulating the association of Cdc24p and Gbeta. Binding experiments demonstrate that Cdc24p, Far1p, and Gbeta form a complex in which pairwise interactions can occur in the absence of the third protein. Cdc24p localizes to sites of polarized growth suggesting that this complex is localized. In the absence of CDC24-FAR1-mediated chemotropism, a bud site selection protein, Bud1p/Rsr1p, is essential for morphological changes in response to pheromone. These results suggest that formation of a Cdc24p-Far1p-Gbetagamma complex functions as a landmark for orientation of the cytoskeleton during growth towards an external signal.  (+info)

Relative dependence of different outputs of the Saccharomyces cerevisiae pheromone response pathway on the MAP kinase Fus3p. (5/1739)

Fus3p and Kss1p act at the end of a conserved signaling cascade that mediates numerous cellular responses for mating. To determine the role of Fus3p in different outputs, we isolated and characterized a series of partial-function fus3 point mutants for their ability to phosphorylate a substrate (Ste7p), activate Ste12p, undergo G1 arrest, form shmoos, select partners, mate, and recover. All the mutations lie in residues that are conserved among MAP kinases and are predicted to affect either enzyme activity or binding to Ste7p or substrates. The data argue that Fus3p regulates the various outputs assayed through the phosphorylation of multiple substrates. Different levels of Fus3p function are required for individual outputs, with the most function required for shmoo formation, the terminal output. The ability of Fus3p to promote shmoo formation strongly correlates with its ability to promote G1 arrest, suggesting that the two events are coupled. Fus3p promotes recovery through a mechanism that is distinct from its ability to promote G1 arrest and may involve a mechanism that does not require kinase activity. Moreover, catalytically inactive Fus3p inhibits the ability of active Fus3p to activate Ste12p and hastens recovery without blocking G1 arrest or shmoo formation. These results raise the possibility that in the absence of sustained activation of Fus3p, catalytically inactive Fus3p blocks further differentiation by restoring mitotic growth. Finally, suppression analysis argues that Kss1p contributes to the overall pheromone response in a wild-type strain, but that Fus3p is the critical kinase for all of the outputs tested.  (+info)

Autoinducer binding by the quorum-sensing regulator TraR increases affinity for target promoters in vitro and decreases TraR turnover rates in whole cells. (6/1739)

TraR is an Agrobacterium transcriptional regulator whose activity requires the pheromone N-3-oxooctanoyl-L-homoserine lactone. TraR was purified as a complex with the pheromone and contained one pheromone molecule per protein monomer. TraR-pheromone complexes bound to a single DNA site and activated two promoters that flank this site. Promoter expression was elevated 30-fold by using a supercoiled template. Pheromone binding increased the affinity of TraR for this binding site. Pheromone also increased TraR abundance in vivo by causing a 20-fold decrease in TraR turnover rates.  (+info)

Comprehensive evaluation of isoprenoid biosynthesis regulation in Saccharomyces cerevisiae utilizing the Genome Reporter Matrix. (7/1739)

Gene expression profiling is rapidly becoming a mainstay of functional genomic studies. However, there have been relatively few studies of how the data from expression profiles integrate with more classic approaches to examine gene expression. This study used gene expression profiling of a portion of the genome of Saccharomyces cerevisiae to explore the impact of blocks in the isoprenoid biosynthetic pathway on the expression of genes and the regulation of this pathway. Approximately 50% of the genes whose expression was altered by blocks in isoprenoid biosynthesis were genes previously known to participate in the pathway. In contrast to this simple correspondence, the regulatory patterns revealed by different blocks, and in particular by antifungal azoles, was complex in a manner not anticipated by earlier studies.  (+info)

The spawning pheromone cysteine-glutathione disulfide ('nereithione') arouses a multicomponent nuptial behavior and electrophysiological activity in Nereis succinea males. (8/1739)

The pheromone nereithione (cysteine-glutathione disulfide), which is released by swimming females of the polychaete Nereis succinea to activate spawning behavior of N. succinea males, has recently been identified and synthesized. Nereithione activates sperm release at less than 10(-6) M, one to two orders of magnitude less than oxidized glutathione or any other glutathione derivative tested. The glutathione fragment gamma-glu-cys inhibited sperm release. Nereithione aroused three components of the male nuptial behavior: circling, sperm release, and accelerated swimming. Electrophysiological activity elicited by nereithione near the sperm release site consisted of initial large spikes, cyclic bursting activity, and small spikes lasting up to a minute and was dose dependent, rapid, reversible, and repeatable. This preparation is an excellent model system for characterizing the receptors and functions of a marine pheromone.  (+info)

The second category includes the aggregation pheromones, alarm pheromones, primer pheromones, and sex pheromones. The primer pheromones are the most uncommon among the four types while the aggregation pheromones are substances that attract both male and female organisms. The latter pheromones are unusual because the typical pheromones attract specific members of the community only; for instance, if youre a man, youll normally attract women. Meanwhile, there are species that, when attacked, release a substance that triggers aggression in other members of the community of that species- a substance called alarm pheromone. But other than aggression, there are also pheromones that lure mates for breeding that are called sex pheromones. Generally, a male insect can sense or detect the pheromones created by a female insect even if he is 10 kilometers away from her. People have an inclination of bragging on the knowledge they have on any particular project. However, we dont want to brag on what we ...
The truth about buying pheromones today are composed of either AlphaAndrostenol (female pheromone) or even AlphaAndrostenone (male pheromone).

Pheromones are highly active chemical messengers which are secreted by a member of an animal species and elicit a definite behavior in other members of the same species. The study of insect pheromones has recently attracted great attention because of their purely scientific interest and their favorable prospects for the control of pest insects. The study in this dissertation aims at the elucidation of some important aspects of the mechanism of perception of insect pheromones, which is based on the fact that the cyclic analogs of the natural pheromone have partially fixed conformations, whereas the straight-chain natural pheromone is more flexible and can adopt numerous conformations. The cyclic compound which best mimics the action of the natural pheromones presumably has a conformation similar to that which the pheromone adopts when bound to the receptor site. The project includes the following: (1) Syntheses of cyclic analogs of natural pheromones: (i) 4-ethyl-3-(5-acetoxypentyl)cyclopentene (20) and
Today, there are many pheromones products in the market, and you most probably wonder what these products, such as the Nexus Pheromones, are for.. The word pheromone originates from theGreek words pherein (to transfer) and hormon (to stimulate). Coined by experts Adolf Butenandt and Peter Karlson in 1959, this term describes the chemical signals among living organisms that elicit response from the physiology or behavior of other members. Pheromones are chemical substances generated by one living organism and are transmitted to other organisms that belong in one species. Pheromones are substances that usually ignite the sexual urge among animals or people.. But for animals, pheromones are commonly used for communication. There are different pheromone types, with each type belonging to two categories of usage: as territory markers or as attraction or aggression starters. The epideictic pheromones, territorial pheromones, and trail pheromones belong to the first category. The epideictic ...

TY - CHAP. T1 - Measuring and Identifying Fish Pheromones. AU - Stewart, Michael. AU - Sorensen, Peter W. PY - 2015/3/16. Y1 - 2015/3/16. N2 - To understand and use fish pheromones, we need to know their concentrations in the water. However, this is a challenging task. Pheromones are usually present in extremely low nanomolar (10-9M) to picomolar (10-12M) concentrations and often in mixtures of subtly different related chemicals. Quantitation can also be complicated by other interfering organic chemicals. Advancements in analytical technology have allowed for more sensitive and accurate determination of pheromone concentrations, but rely on the availability of authentic standards. Perhaps, an even greater challenge than measuring known pheromones is the identification of new pheromones from fish, which requires a multidisciplinary effort. This chapter reviews why and how we can measure known pheromones and approaches to identify unknown structures.. AB - To understand and use fish pheromones, we ...

Some pheromones are absorbed into the skin and may stay there for a longer period of time. Usually, depending on the biochemical characteristics of your skin, pheromones remain on your skin for about five hours, and up to ten hours on your clothing. Pheromone build-up happens when the skin absorbs so much pheromone content from multiple pheromone applications over a period of time, that you notice a significant drop off in the effectiveness of a pheromone product. If you see no good reactions after you use pheromones or you see better reactions when you dont apply pheromones - you have this problem. To prevent this dont apply products directly to the skin - apply them to your clothing instead. Clothing applications can be more convenient and will last longer ...
Pheromones that are created generally peak around 18 to 20 years of age and begin to wane at approximately 40 years of age. The signals that 18 year olds give off are so strong that people of all age groups are generally drawn to look at them. However, there have been studies that show direct correlation to pheromones and the physiological reactions that they cause to our sense of smell. The better a persons sense of smell, the stronger his or her reaction will be to a pheromone signal that they receive. Because of this correlation and the fact that people around the age of 40 have a lower pheromone signal or pheromone reaction could be tied to the fact that age affects ones sense of smell. And as the sense of smell decreases and becomes less prominent, so too does the reaction to pheromone signals that may be sensed ...
Kulshan Veterinary Hospital. Pheromones are chemicals secreted by an animal whose purpose is to influence the behavior of the receiving animal of the same species. There are many different pheromones for influencing many different categories of behavior. For instance, some pheromones are designed to alert or alarm other individuals to a threat. Other examples of types of behavior that pheromones influence include sex, food trail, territory, and many others. The sensory organ that receives the signal is the vomeronasal organ, which is at the base of the nasal septum between the nose and mouth. The chemical signal triggers the release of neurotransmitters in the brain, affecting behavior.. Mares release a soothing pheromone from their mammary glands called Equine Appeasing Pheromone that sends a calming signal to her foal indicating that the environment is safe and secure.

The conception can happen only in the fertile window. With the pheromone theory in mind, the cycle starts there. That is, a woman in her fertile window can secrete pheromones (androstenol) that subliminally help attract males, who are also releasing their attraction pheromones.. Certain studies have shown that female body odors during ovulation are deemed more pleasant than those of women who are currently menstruating. So, in conclusion, we can say with a healthy dose of certainty that the release of hormones is a recurring, cyclical event, where one response triggers the other.. There is still a lot of research up ahead when it comes to pheromones and behavioral responses to them. Some of the sex pheromones we have mentioned have proven to be existent and having some benefits in attracting a mate. The presence of the pheromones from axillary sweat, however, still needs further exploration.. RELATED: Do Pheromones Play a Role in Our Sex Lives?. As the study methodology of the pheromones ...

Location of the VNO in the human nasal Cavity There are countless studies and reports that PROVE the effects of human sex pheromones, demonstrating that humans DO produce and DO react to pheromones!??For example, in controlled experiments, women exposed to mens axillary pheromones found the men they viewed MUCH more sexually attractive! Another study revealed that 74% of women, when exposed to sex pheromones, reported more sexual intercourse with men! They also reported increases in formal dates, petting, affection, kissing, and a greater desire to sleep closer to their partner! A similar study conducted with men exposed to sex pheromones concluded with similar results, as men reported more sexual intercourse, affection, kissing, and dates! Further discoveries in science are supporting the influence of pheromones on human sexual behavior with the discovery of the gene V1RL1 that codes for a pheromone receptor in people!???? ?? ?? ?? ?? ?? ?? ?? ?? ??Read More ...

Rather, males walk in a nearly straight line, steering directly upwind, in contrast to flying males, which steer a course alternating back and forth about 15-20° ...
Previous research has revealed that natural and synthetic pheromones can enhance ratings of opposite sex attractiveness. The present study investigated the effects of exposure to male axillary secretions on female ratings of the sexual attractiveness of male stimuli. Thirty-two female undergraduates, half of whom were contraceptive pill users, rated male vignette characters and photographs of male faces on aspects of attractiveness. On two separate study days, corresponding to different phases of their menstrual cycle, stimuli were presented while exposed to male axillary pheromones and under a control condition (no pheromone). The order of testing was balanced with respect to pheromone/control condition and menstrual cycle phase. Pheromone exposure resulted in significantly higher attractiveness ratings of vignette characters and faces. Use of the contraceptive pill or menstrual cycle phase had equivocal effects on some vignette items and neither had any influence on female ratings of male ...
Genes required for mating by a and α cells of Saccharomyces cerevisiae (STE, sterile, genes) encode products such as peptide pheromones, pheromone receptors, and proteins responsible for pheromone processing. a-specific STE genes are those required for mating by a cells but not by α cells. To identify new a-specific STE genes, we have employed a novel strategy that enabled us to determine if a ste mutant defective in mating as a is also defective in mating as α without the need to do crosses. This technique involved a strain (K12-14b) of genotype mata 1 HML? HMR? sir3ts, which mates as a at 25° and as α at 34°. We screened over 40,000 mutagenized colonies derived from K12-14b and obtained 28 a-specific ste mutants. These strains contained mutations in three known a-specific genes- STE2, STE6 and STE14-and in a new gene, STE16. ste16 mutants are defective in the production of the pheromone, a-factor, and exhibit slow growth. Based on the distribution of a-specific ste mutants described ...
Sex and aggregation pheromones consist of species-specific blends of chemicals. The way in which different species blends have evolved has been the subject of some debate. Theoretical predictions suggest that differences between species have arisen not through the accruing of small changes, but through major shifts in chemical composition. Using data on the aggregation pheromones of 34 species of bark beetle from two genera, Dendroctonus and Ips, we investigated how the distributions of the chemical components of their pheromone blends mirror their phylogenetic relationships. We tested whether there were consistent patterns that could be used to help elucidate the mode of pheromone evolution. Although there were obvious differences in pheromone blends between the two genera, the differences between species within each genus followed a less clear phylogenetic pattern. In both genera, closely related species are just as different as more distantly related species. Within Dendroctonus, ...

Many people have heard about the use of pheromones in the animal kingdom. Not everybody knows that these amazingly powerful chemical signals can also help humans out. Most humans are still producing pheromones on a fairly low scale. The most important thing to know about pheromones is that the human nose can detect them, and the human mind can interpret them.. Pheromones are primitive chemical signals that are no longer recognizable to the conscious mind. They are however recognizable to the unconscious mind. There are powerful receptors in the human nose and brain that still recognize these chemical signals. The person may not be aware of a smell, but it is certainly registering in the brain. These signals can influence and enhance attraction and romance. University of Colorado and Utah researchers discovered that pheromones are actually received in the vomeronasal organ of the nose. This powerful, tiny organ can actually receive these subtle chemical signals. This organ then sends feedback to ...
French scientists were the first to identify this particular pheromone which is found in all lactating mammals, between three and five days after giving birth. Produced by the mammary glands, it is passed from the mother to her offspring and conveys constant reassurance: it is natures ultimate feeling of security and anti-anxiety.. Taking this information, the French team went on to produce a synthetic version of this natural feel-good pheromone. This was launched in the UK earlier this year as a dog-appeasing pheromone - DAP - diffuser. For the past couple of years, University of Lincoln vets and welfare group, have been working with the dog-appeasing pheromone to assess its value in the treatment of stressed and troubled dogs and cats. For the first time we have the opportunity to recognise and understand how dogs and cats produce their own natural calm, and how that can be enhanced when they are faced with undue amounts of stress, says Professor Daniel. The kind of stress that is often ...
Please remember however, that pheromones are synthetic concentrated body odors and as such may not be very pleasant smelling. A cologne or fragrence is advised to also help exalt or lift the pheromone molecules off your skin into the air around you. This process is called diffusion. Without good diffusion a person will need to be very close to the application point to be affected by the pheromones. The more diffusive a pheromone application is the more powerful the results will be and the more people your silage will affect. pheromoneXS uses our Advanced Diffusion Technology ADT so you get consistent results with or without cologne or fragrance..

Androsterone can be worn by women, though the effects of the pheromone are not as strong when women wear it. Men will usually experience an elevated mood when detecting this pheromone on a woman. Androsterone is usually mixed with other pheromones in order to enhance the effectiveness of the other chemicals, as it acts as a subtle boost to the other pheromones that will make them and it more effective. There are no effects resulting from too much androsterone, making it one of the best and strongest pheromones. ...

Conjugative transfer of the Enterococcus faecalis plasmid pCF10 is induced by the peptide pheromone cCF10 when recipient-produced cCF10 is detected by donors. cCF10 is produced by proteolytic processing of the signal sequence of a chromosomally encoded lipoprotein (CcfA). In donors, endogenously produced cCF10 is carefully controlled to prevent constitutive expression of conjugation functions, an energetically wasteful process, except in vivo, where endogenous cCF10 induces a conjugation-linked virulence factor. Endogenous cCF10 is controlled by two plasmid-encoded products; a membrane protein PrgY reduces pheromone levels in donors, and a secreted inhibitor peptide iCF10 inhibits the residual endogenous pheromone that escapes PrgY control. In this study we genetically determined the amino acid specificity determinants within PrgY, cCF10, and the cCF10 precursor that are necessary for cCF10 processing and for PrgY-mediated control. We showed that amino acid residues 125 to 241 of PrgY are ...
A part of the body found in the roof of the mouth of most, if not all mammals is thought to play a large role in the detection of pheromones. This section of the mouth, known as the vomeronasal organ or VNO in short is connected though not directly to the olfactory system develops before birth and becomes fully-formed in a few short months. The VNO is designed to detect molecules dissolved in liquids, which makes sense given how pheromones are delivered.. Pheromones are mostly expressed through sweat. However, they are also expressed via sexual fluids as well as saliva and urine. This makes the licking and overt sniffing action of animals such as dogs seem logical and natural; this is their way of finding potential genetic mates as well as sussing out dominance as well as asserting their claim over certain territories.. Scientists are still on the fence with regard to the effectiveness of pheromones. This is because some people are affected by certain pheromones, while others are not. It has ...

Today, there are many pheromones products in the market, and you most probably wonder what these products, such as the Nexus Pheromones, are for.. The word pheromone originates from theGreek words pherein (to transfer) and hormon (to stimulate). Coined by experts Adolf Butenandt and Peter Karlson in 1959, this term describes the chemical signals among living organisms that elicit response from the physiology or behavior of other members. Pheromones are chemical substances generated by one living organism and are transmitted to other organisms that belong in one species. Pheromones are substances that usually ignite the sexual urge among animals or people.. But for animals, pheromones are commonly used for communication. There are different pheromone types, with each type belonging to two categories of usage: as territory markers or as attraction or aggression starters. The epideictic pheromones, territorial pheromones, and trail pheromones belong to the first category. The epideictic ...
Its not just sexual attraction that appears to be boosted by wearing pheromones. Users of pheromone products report that people generally pay more attention to them, listen more when they speak, and are friendlier in social situations. Pheromones seem to affect peoples general impressions and assessments. In one clinical study participants wearing surgical masks were shown photographs of buildings, trees, animals, women and men. Their task was to assess each according to impressions of friendly/unfriendly, aggressive/passive, attractive/unattractive and so on. The purpose of the test, they were told, was to examine how stress related to wearing a surgical mask affected decision-making. Participants were tested twice, with a two-week interval between sessions. For one of the tests small quantities of pheromones were sprayed on the mask, without the participants knowledge. With the added pheromone there was no noticeable difference in the study groups impressions of trees and buildings. ...

Sst2 is the prototype for the newly recognized RGS (for regulators of G-protein signaling) family. Cells lacking the pheromone-inducible SST2 gene product fail to resume growth after exposure to pheromone. Conversely, overproduction of Sst2 markedly enhanced the rate of recovery from pheromone-induced arrest in the long-term halo bioassay and detectably dampened signaling in a short-term assay of pheromone response (phosphorylation of Ste4, Gbeta subunit). When the GPA1 gene product (Galpha subunit) is absent, the pheromone response pathway is constitutively active and, consequently, growth ceases. Despite sustained induction of Sst2 (observed with specific anti-Sst2 antibodies), gpa1delta mutants remain growth arrested, indicating that the action of Sst2 requires the presence of Gpa1. The N-terminal domain (residues 3 to 307) of Sst2 (698 residues) has sequence similarity to the catalytic regions of bovine GTPase-activating protein and human neurofibromatosis tumor suppressor protein; segments ...
Sexual attraction as a result of pheromone production has also been theoretically linked to the connection between the production of pheromones in the sweat glands and the males that sweat the most, in some as species this is an indicator of that male being strongest, most active and healthiest of the males in the group. Therefore, the more sweat, the more pheromones, the more pheromones the more the females would find that male attractive and as a result want to mate with that male. ...

Ciliates synthesize cell type-specific chemical signals, designated pheromones, that in association with their mating type systems control the switching between the reproductive (mitotic growth) and mating (non-reproductive, sexual) stages of their life cycles. In the protozoan ciliate Euplotes, pheromones have been isolated and characterized for their genetic determination and molecular structures and interestingly, Euplotes raikovi pheromones (designed as Er-1, Er-2, and so forth) have been functionally linked with growth factors of higher eukaryotes as for instance the epidermal growth factor and the cytokine interleukin-2 (IL-2). However, the activity of pheromones in mammalian cells and their underlying cellular basis are currently unknown. In an attempt to elucidate the pharmacological features and the functional effects of Er-1 in human cells, we have performed an in vitro study using Jurkat cells (IL-2 producing human T lymphocyte cell line, commonly used to study T cell signalling), ...
He argues that there is little or no scientific basis for human pheromones in the scientific literature. The vomeronasal organ, which is the sensory organ that takes in pheromone compounds in mammals such as mice and rats is a vestigial organ in humans. Menstrual synchrony has long been viewed as a physiological phenomenon in humans that could only be explained by the exchange of pheromones among women. He argues, however, that methodological critiques of menstrual cycle research and recent research indicate the menstrual synchrony does not occur among women. Finally, he reviews the literature on human pheromones and argues that there are serious methodological issues in all studies reporting human pheromones and that no human pheromone has ever been definitively identified.[2]. His conclusion is that human pheromones are a myth that is driven in part by economics. What he calls the junk-science industry of pheromone-perfumes, pheromone-soaps, and pheromone cosmetics arose from misunderstood ...
About Pheromones in Humans Human pheromones have been around for a long time. Humans do not have a VNO structure, or perhaps we do, but they are regarded as being dormant and ineffective, and this is why scientists have postulated that humans do not respond to pheromones. By definition and according to evolutionary theory, pheromones work within a species. These pheromones are detected by us through the nose in the Vomeronasal Organ. How do pheromones work? Mammals, including humans, also give off a cloud of molecules that represent our unique individual smell or chemical profile.

Although mass trapping cannot be a definitive control measure, it is one of the few ones available to contain the destruction of millions of cubic metres of conifer forests perpetrated every year worldwide by bark beetles. However, using bark beetle aggregation pheromones during both monitoring and control programs may negatively affect other saproxylic insects. The aim of this study was to describe the response of both Ips sexdentatus and its saproxylic beetle associates, especially predators, to traps baited with a commercial blend of I. sexdentatus aggregation pheromone. Furthermore, the usefulness of adding pine volatiles, such as (−)-α-pinene and ethanol, to the pheromone was discussed. The commercial blend proved to be attractive to I. sexdentatus adults, both when used alone and together with pine volatiles. Pheromone attractiveness, however, was lessened by the addition of the volatiles. The pheromone blend proved to be attractive to Thanasimus formicarius, as well as to other ...
Determination of the optimal insemination time in dairy cows is vital for fertilization success and is a challenging task due to silent or weak signs of estrus shown by some cows. This can be overcome by combining several estrus detection methods, leading to higher detection rates. However, an efficient, noninvasive method for detecting estrus in cows is still needed. Chemical cues released by the cow during estrus have been proposed to have pheromonal properties and signal readiness to mate to the bull. Such cues could be used in an industrial setting to detect cows in estrus. However, no conclusive published data show temporal changes in putative sex pheromone levels during estrus. The goal of this study was to determine the temporal pattern of putative sex pheromone components during estrus and to assess the reproducibility of changes in pheromone concentration with respect to ovulation time. Two injections of the hormone PGF(2 alpha) were administered over a 2-wk interval to induce and ...
If youre looking for the woman or man of your dreams, remember that pheromones in your body scent are playing a large role in mate attraction. People who use commercial pheromone products claim that the product (pheromone perfume, cologne or oil) they use increases their attractiveness to members of the opposite sex. Also, one of the most important effects of pheromones is in their ability to make the wearer of the pheromone cologne feel confident. But its not just sexual attraction that is increased by wearing pheromones. Users of pheromone perfumes report that people pay more attention to them and are generally more friendly to them ...

The effects of lures containing aphid sex pheromone components (4aS,7S,7aR)-nepetalactone and (1R,4aS,7S,7aR)-nepetalactol on abundance of pea aphid, Acyrthosiphon pisum Harris, aphid parasitoids, predators and hyperparasitoids in alfalfa fields were investigated over three years. Although aphid abundance was variable among years, pheromone lure treatment significantly decreased aphid abundance. Among natural enemies of the aphids, only parasitism by the aphid parasitoids Aphidius ervi Haliday and Praon barbatum Mackauer was affected by pheromone lure treatment, with parasitism rates being significantly increased. In contrast, no pheromone lure effects on abundance were detected for predacious species and hyperparasitoids. These results indicate that slow-release formulations of synthetic aphid sex pheromone can attract primary aphid parasitoids and enhance their ability to suppress aphid abundance in the field, and that negative effects on biological control by hyperparasitoids and intraguild ...
4-Methyl-5-nonanol (1) is the male-produced aggregation pheromone of the palm weevil, Dynamis borassi (F.) from Colombia. The pheromone was identified by coupled gas chromatographic-electroantennographic detection (GC-EAD) analysis of male- and female-produced volatiles, and comparative GC-mass spectrometry (MS) of weevil-produced 1. In field experiments in Colombia, traps baited with a stereoisomeric mixture of synthetic 1 (3 mg/day) plus sugarcane captured more weevils than traps baited with 1 or sugarcane alone, suggesting that pheromone and plant volatiles are synergistically attractive. Use of a chiral, stereoisomer-separating Cyclodex-B column in GC-EAD and GC-MS analyses revealed that D. borassi males produce, and antennae of males and females respond to (4S,5S)-1. Previously identified palm weevil (Rhynchophorus spp.) aggregation pheromones 5-methyl-4-octanol (cruentol) and 6-methyl-2-hepten-4-ol (rhynchophorol) also elicited antennal responses by D. borassi. In field experiments, D. ...

Scientists have identified the first human gene that may be linked to pheromones, odorless molecules that in other animals trigger primal urges including sex, defense and kinship.. Experts describe the discovery as possibly opening a new door into the role of pheromones in human development.. In animals, researchers have documented how pheromones trace complex neurological paths to stimulate parts of the brain that are deeply rooted in instinct.. Researchers have long believed that humans also communicate through pheromones, but until now they had been unable to find any of the equipment needed to detect these potent molecules.. Now, in experiments at Rockefeller University and Yale, neurogeneticists have isolated a human gene, labeled V1RL1, that they believe encodes for a pheromone receptor in the mucous lining of the nose. A receptor is a patch on the surface of a cell that binds with specific molecules, like a lock that accepts only a specific key.. This is the first convincing ...

Olfactory information mediating sexual behavior is crucial for reproduction in many animals, including insects. In male moths, the macroglomerular complex of the primary olfactory center, the antennal lobe (AL) is specialized in the treatment of information on the female-emitted sex pheromone. Evidence is accumulating that modulation of behavioral pheromone responses occurs through neuronal plasticity via the action of hormones and/or catecholamines. We recently showed that a G-protein-coupled receptor (GPCR), AipsDopEcR, with its homologue known in Drosophila for its double affinity to the main insect steroid hormone 20-hydroxyecdysone (20E), and dopamine (DA), present in the ALs, is involved in the behavioral response to pheromone in the moth, Agrotis ipsilon. Here we tested the role of AipsDopEcR as compared to nuclear 20E receptors in central pheromone processing combining receptor inhibition with intracellular recordings of AL neurons. We show that the sensitivity of AL neurons for the pheromone in
Love changes everything, people say. Valentines Day is the day of love. Especially on that day, pheromones are advertised and sold as cologne or perfume in order to stimulate attraction between people. However, the question is: do sexual pheromones really exist, and how good are they?. Pheromones are chemosignals transmitting gender-specific information. The most widely studied human pheromone is AND (Δ4,16-androstadien-3-one) which is secreted by axillary sweat. There are higher concentrations of AND in male than in female axillary sweat. These findings led some researchers to the idea that AND is involved especially in human attraction.

Pheromones have been studied for 30+ years but still very little is known. A lot of products out there are using this to launch scams and pheromone products that do not work. But as soon as you know and have done enough research, you will understand that there are only 3 known human pheromone substances that are worth buying which are androstenone, androsterone and androstenol. These 3 already have a chemical name, a chemical formula which is widely accepted to be pheromones. So if you are mixing pheromones, it is highly recommended to get products that are pure androstenone, androsterone and androstenol. You can then start creating your own ratio and mixes ...

Both mechanistic and evolutionary studies of sexual communication in moths have concentrated on long-range sexual signaling - females emit a sex pheromone to which males are attracted. Courtship behavior, which includes emission of a close-range sex pheromone by the male, female assessment of the male, and ultimately acceptance or rejection of the courting male, has been investigated mainly in species in which males obtain pheromone or its precursors from plants and bias female choice with nuptial gifts. In most moth species, however, male close-range pheromones are synthesized de novo from similar precursors that are used by females to biosynthesize the female pheromone. In these moth species the male pheromone is important for species-recognition and female acceptance of males. We are addressing the following questions: (a) How does natural variation in close-range sexual signals affect female choice in moth species where the male pheromone resembles the female pheromone? (b) Is the production ...

Sexual attraction has been particularly well-studied in moths, in which females of almost all species produce pheromones to attract males for mating. Since 1959, when the first sex pheromone was identified in the domestic silk moth, the sex pheromones of hundreds of moth species, as well as those of flies, bees, beetles and other insects, have been discovered. During the last 15 years, scientists have accumulated a wealth of knowledge about the insect biosynthetic enzymes involved in production of pheromone components.. In a new review article from the journal Zeitschrift für Naturforschung C, the authors Tupec, Buček, Valterová and Pichová show that there are nearly 100 experimentally characterized insect enzymes involved in biosynthesis of fatty acids and related chemicals.. These unique enzymes have potential applications for bio-production of cosmetics, glues or compounds that improve the properties of plastics. The artificial biosynthesis of such chemicals by living organisms, such as ...
Attracting the opposite gender is usually a hard task for many people, particularly for guys who require the necessary physical feature to easily attract ladies for affectionate love or perhaps for one-night stands. However, other than the physical characteristic of a person, there are also elements that can significantly affect the success of getting the opposite intimacy, and this it isnt just exclusive for the men, nonetheless also among the list of women.

And similar to that in family pets and bugs, human pheromones also works as an ...
The Potato virus Y (PVY) Potyvirus is transmitted to potatoes in a non-persistent manner by aphids. E-B-Farnesene (EBF) is a largely interspecific aphid alarm pheromone which, depending on multiple factors, might have an impact on aphids feeding, winging, moving or escaping behaviors. In addition, predators and parasitoids may also be stimulated by EBF to find aphids. In preliminary field trials, EBF had been shown to impact PVY field transmission by aphids. With the view of developing an innovative biocontrol method for PVY infestations on potatoes, we assessed the impact of EBF on the virus propagation under field trials carried out in 2013. To ensure both virus and vector pressure, PVY was inoculated on 11% of the plants. Aphids (Myzus persicae) were artificially introduced in the plots. Potato leaves were sampled at four collection dates during the growing season and stored at -20°C before RNA extractions. Quantitative RT-PCR was performed to determine the PVY infection rates in the potato ...

Androsterone then again is a masculine pheromone that lacks the aggressive vibe produced by androstenone. From here signals are despatched by neurons (nerves) to the accent olfactory bulbs, which is the part of the brain liable for processing the data relayed by the pheromones and mediating a response. Curiously, essentially the most considerable pheromone on the market is androstenone , but this pheromone has been shown to don`t have any motion within the VNO. It picks up scents that aren`t normally detected, ones that carry an excessive amount of details about an individual. It might therefore be doable to tailor a pheromone combine specifically for an individual, in essence creating the impression of a great companion, but in the meanwhile that is beyond current know-how.

Insect pheromone trap on a fruit tree. The trap releases chemicals similar to the pheromones used by insects to attract a mate. When the insects land on the trap they become stuck to its sticky surface. Traps such as this are used to collect insects and to control agricultural pests. The traps act as early warning systems, allowing the detection of adult insect emergence and the monitoring of pest populations. This enables insecticide to be sprayed only when and where it is needed. Photographed in an orchard in France. - Stock Image C022/5471
