HSP27 multimerization mediated by phosphorylation-sensitive intermolecular interactions at the amino terminus. (1/1413)
Distinct biochemical activities have been reported for small and large molecular complexes of heat shock protein 27 (HSP27), respectively. Using glycerol gradient ultracentrifugation and chemical cross-linking, we show here that Chinese hamster HSP27 is expressed in cells as homotypic multimers ranging from dimers up to 700-kDa oligomers. Treatments with arsenite, which induces phosphorylation on Ser15 and Ser90, provoked a major change in the size distribution of the complexes that shifted from oligomers to dimers. Ser90 phosphorylation was sufficient and necessary for causing this change in structure. Dimer formation was severely inhibited by replacing Ser90 with Ala90 but not by replacing Ser15 with Ala15. Using the yeast two-hybrid system, two domains were identified that were responsible for HSP27 intermolecular interactions. One domain was insensitive to phosphorylation and corresponded to the C-terminal alpha-crystallin domain. The other domain was sensitive to serine 90 phosphorylation and was located in the N-terminal region of the protein. Fusion of this N-terminal domain to firefly luciferase conferred luciferase with the capacity to form multimers that dissociated into monomers upon phosphorylation. A deletion within this domain of residues Arg5-Tyr23, which contains a WDPF motif found in most proteins of the small heat shock protein family, yielded a protein that forms only phosphorylation-insensitive dimers. We propose that HSP27 forms stable dimers through the alpha-crystallin domain. These dimers further multimerize through intermolecular interactions mediated by the phosphorylation-sensitive N-terminal domain. (+info)Photorhabdus luminescens W-14 insecticidal activity consists of at least two similar but distinct proteins. Purification and characterization of toxin A and toxin B. (2/1413)
Both the bacterium Photorhabdus luminescens alone and its symbiotic Photorhabdus-nematode complex are known to be highly pathogenic to insects. The nature of the insecticidal activity of Photorhabdus bacteria was investigated for its potential application as an insect control agent. It was found that in the fermentation broth of P. luminescens strain W-14, at least two proteins, toxin A and toxin B, independently contributed to the oral insecticidal activity against Southern corn rootworm. Purified toxin A and toxin B exhibited single bands on native polyacrylamide gel electrophoresis and two peptides of 208 and 63 kDa on SDS-polyacrylamide gel electrophoresis. The native molecular weight of both the toxin A and toxin B was determined to be approximately 860 kDa, suggesting that they are tetrameric. NH2-terminal amino acid sequencing and Western analysis using monospecific antibodies to each toxin demonstrated that the two toxins were distinct but homologous. The oral potency (LD50) of toxin A and toxin B against Southern corn rootworm larvae was determined to be similar to that observed with highly potent Bt toxins against lepidopteran pests. In addition, it was found that the two peptides present in toxin B could be processed in vitro from a 281-kDa protoxin by endogenous P. luminescens proteases. Proteolytic processing was shown to enhance insecticidal activity. (+info)In vivo regulation of beta-MHC gene in rodent heart: role of T3 and evidence for an upstream enhancer. (3/1413)
Cardiac beta-myosin heavy chain (beta-MHC) gene expression is mainly regulated through transcriptional processes. Although these results are based primarily on in vitro cell culture models, relatively little information is available concerning the interaction of key regulatory factors thought to modulate MHC expression in the intact rodent heart. Using a direct gene transfer approach, we studied the in vivo transcriptional activity of different-length beta-MHC promoter fragments in normal control and in altered thyroid states. The test beta-MHC promoter was fused to a firefly luciferase reporter gene, whereas the control alpha-MHC promoter was fused to the Renilla luciferase reporter gene and was used to account for variations in transfection efficiency. Absolute reporter gene activities showed that beta- and alpha-MHC genes were individually and reciprocally regulated by thyroid hormone. The beta-to-alpha ratios of reporter gene expression demonstrated an almost threefold larger beta-MHC gene expression in the longest than in the shorter promoter fragments in normal control animals, implying the existence of an upstream enhancer. A mutation in the putative thyroid response element of the -408-bp beta-MHC promoter construct caused transcriptional activity to drop to null. When studied in the -3, 500-bp beta-MHC promoter, construct activity was reduced ( approximately 100-fold) while thyroid hormone responsiveness was retained. These findings suggest that, even though the bulk of the thyroid hormone responsiveness of the gene is contained within the first 215 bp of the beta-MHC promoter sequence, the exact mechanism of triiodothyronine (T3) action remains to be elucidated. (+info)Glucose generates sub-plasma membrane ATP microdomains in single islet beta-cells. Potential role for strategically located mitochondria. (4/1413)
Increases in the concentration of free ATP within the islet beta-cell may couple elevations in blood glucose to insulin release by closing ATP-sensitive K+ (KATP) channels and activating Ca2+ influx. Here, we use recombinant targeted luciferases and photon counting imaging to monitor changes in free [ATP] in subdomains of single living MIN6 and primary beta-cells. Resting [ATP] in the cytosol ([ATP]c), in the mitochondrial matrix ([ATP]m), and beneath the plasma membrane ([ATP]pm) were similar ( approximately 1 mM). Elevations in extracellular glucose concentration (3-30 mM) increased free [ATP] in each domain with distinct kinetics. Thus, sustained increases in [ATP]m and [ATP]pm were observed, but only a transient increase in [ATP]c. However, detectable increases in [ATP]c and [ATP]pm, but not [ATP]m, required extracellular Ca2+. Enhancement of glucose-induced Ca2+ influx with high [K+] had little effect on the apparent [ATP]c and [ATP]m increases but augmented the [ATP]pm increase. Underlying these changes, glucose increased the mitochondrial proton motive force, an effect mimicked by high [K+]. These data support a model in which glucose increases [ATP]m both through enhanced substrate supply and by progressive Ca2+-dependent activation of mitochondrial enzymes. This may then lead to a privileged elevation of [ATP]pm, which may be essential for the sustained closure of KATP channels. Luciferase imaging would appear to be a useful new tool for dynamic in vivo imaging of free ATP concentration. (+info)Molecular systematics of cytochrome oxidase I and 16S from Neochlamisus leaf beetles and the importance of sampling. (5/1413)
If a gene tree is to be judiciously used for inferring the histories of closely related taxa, (1) its topology must be sufficiently resolved and robust that noteworthy phylogenetic patterns can be confidently documented, and (2) sampling of species, populations, and pertinent biological variation must be sufficiently broad that otherwise misleading sources of genetic variation can be detected. These principles are illustrated by the complex gene tree of Neochlamisus leaf beetles that I reconstructed using 90,000 bp of cytochrome oxidase I (COI) and 16S mitochondrial DNA (mtDNA) sequences from over 100 specimens. Cytochrome oxidase I haplotypes varied up to 25.1% within Neochlamisus and up to 11.1% within the gibbosus species group, while exhibiting very low A + T bias for insect mtDNA (63%), low transition saturation, and conservative patterns of amino acid variation. 16S exhibited lower sequence divergences and greater A + T bias and transition saturation than COI, and substitutions were more constrained in stems than in loops. Comparisons with an earlier study of Ophraella leaf beetles highlighted conservative and labile elements of molecular evolution across genes and taxa. Cytochrome oxidase I parsimony and neighbor-joining analyses strongly supported a robust mtDNA genealogy that revealed the monophyly of Neochlamisus and of the gibbosus species group. Phylogeographic relationships suggested that the eastern U.S. gibbosus group derives from southwestern velutinus group ancestors. Haplotypes from individual velutinus group species clustered monophyletically, as expected. However, haplotypes from each of several gibbosus group taxa were polyphyletically distributed, appearing in divergent parts of the tree. 16S provided a less-resolved gibbosus group topology that was congruent with the COI tree and corroborated patterns of mitochondrial polyphyly. By subsampling haplotypes corresponding to particular species, populations, and ecological variants of gibbosus group taxa, I demonstrate that recovered topologies and genetic distances vary egregiously according to sampling regime. This study thus documents the potentially dire consequences of inadequate sampling when inferring the evolutionary history of closely related and mitochondrially polyphyletic taxa. (+info)A visual evoked potential correlate of global figure-ground segmentation. (6/1413)
Human observers discriminated the global orientation of a texture-defined figure which segregated from a texture surround. Global figure discriminability was manipulated through within-figure collinearity, figure-surround interaction, and figure connectedness, while the local orientation contrast at edges between figure and surround was kept constant throughout all the experiments. Visual evoked potentials (VEPs) were recorded during onset-offset stimulation in which the figure cyclically appeared and disappeared from a uniform texture background. A difference component was obtained by subtraction of offset-from onset-VEP. Two negative peaks of the difference component are found with latencies around 140-160 and 200-260 ms, respectively. Enhanced discriminability of the global figure reduced (11-25 ms) the latency of the second peak, hence indicating that the 200-260 ms component was produced by global figure-ground segmentation. (+info)Seeing better at night: life style, eye design and the optimum strategy of spatial and temporal summation. (7/1413)
Animals which need to see well at night generally have eyes with wide pupils. This optical strategy to improve photon capture may be improved neurally by summing the outputs of neighbouring visual channels (spatial summation) or by increasing the length of time a sample of photons is counted by the eye (temporal summation). These summation strategies only come at the cost of spatial and temporal resolution. A simple analytical model is developed to investigate whether the improved photon catch afforded by summation really improves vision in dim light, or whether the losses in resolution actually make vision worse. The model, developed for both vertebrate camera eyes and arthropod compound eyes, calculates the finest spatial detail perceivable by a given eye design at a specified light intensity and image velocity. Visual performance is calculated for the apposition compound eye of the locust, the superposition compound eye of the dung beetle and the camera eye of the nocturnal toad. The results reveal that spatial and temporal summation is extremely beneficial to vision in dim light, especially in small eyes (e.g. compound eyes), which have a restricted ability to collect photons optically. The model predicts that using optimum spatiotemporal summation the locust can extend its vision to light intensities more than 100,000 times dimmer than if it relied on its optics alone. The relative amounts of spatial and temporal summation predicted to be optimal in dim light depend on the image velocity. Animals which are sedentary and rely on seeing small, slow images (such as the toad) are predicted to rely more on temporal summation and less on spatial summation. The opposite strategy is predicted for animals which need to see large, fast images. The predictions of the model agree very well with the known visual behaviours of nocturnal animals. (+info)Sequencing and characterization of the citrus weevil, Diaprepes abbreviatus, trypsin cDNA. Effect of Aedes trypsin modulating oostatic factor on trypsin biosynthesis. (8/1413)
Trypsin mRNA from the citrus weevil, Diaprepes abbreviatus, was reverse transcribed and amplified by PCR. A cDNA species of 513 bp was cloned and sequenced. The 3' and 5' ends of the gene (262 bp and 237 bp, respectively) were amplified by rapid amplification of cDNA ends, cloned and sequenced. The deduced sequence of the trypsin cDNA (860 bp) encodes for 250 amino acids including 11 amino acids of activation and signal peptides and exhibited 16.8% identity to trypsin genes of selected Lepidoptera and Diptera. A three-dimensional model of Diaprepes trypsin contained two domains of beta-barrel sheets as has been found in Drosophila and Neobellieria. The catalytic active site is composed of the canonical triad of His41, Asp92 and Ser185 and a specificity pocket occupied by Asp179 with maximal activity at pH 10.4. Southern blot analysis indicated that at least two copies of the gene are encoded by Diaprepes midgut. Northern blot analysis detected a single RNA band below 1.35 kb at different larval ages (28-100 days old). The message increased with age and was most abundant at 100 days. Trypsin activity, on the other hand, reached a peak at 50 days and fell rapidly afterwards indicating that the trypsin message is probably regulated translationally. Feeding of soybean trypsin inhibitor and Aedes aegypti trypsin modulating oostatic factor affected trypsin activity and trypsin biosynthesis, respectively. These results indicate that Diaprepes regulates trypsin biosynthesis with a trypsin modulating oostatic factor-like signal. (+info)"Beetles" is not a medical term. It is a common name used to refer to insects belonging to the order Coleoptera, which is one of the largest orders in the class Insecta. Beetles are characterized by their hardened forewings, known as elytra, which protect their hind wings and body when not in use for flying.
There are many different species of beetles found all over the world, and some can have an impact on human health. For example, certain types of beetles, such as bed bugs and carpet beetles, can cause skin irritation and allergic reactions in some people. Other beetles, like the Colorado potato beetle, can damage crops and lead to economic losses for farmers. However, it is important to note that most beetles are not harmful to humans and play an essential role in ecosystems as decomposers and pollinators.
"Tribolium" is not a term commonly used in medical definitions. It is actually the name of a genus of beetles, also known as flour beetles, which are often used in scientific research, particularly in the fields of genetics and evolution. If you have any confusion with a specific medical context where this term was used, I would recommend checking the source again for clarification.
"Tenebrio" is the genus name for mealworm beetles, which are insects commonly found in stored grains and animal feed. The most common species is Tenebrio molitor. Mealworms and their larvae are often used as a food source for pets, such as reptiles and birds, but they can also cause damage to crops and structures if they infest them. They have been studied in various medical and scientific research fields including nutrition, toxicology, and allergies. Some people may have allergic reactions to mealworms or their byproducts.
I am not aware of a medical condition called "horns." The term "horns" is commonly used to refer to a hard, pointed projection on the head of certain animals, such as cattle or antelopes. In humans, abnormal growths that resemble horns are usually referred to as "cutaneous horns," which are benign or malignant skin tumors that protrude from the skin in a conical shape. They typically occur on sun-exposed areas of the body, such as the face and scalp. However, it's important to note that medical conditions can vary widely, and it's always best to consult with a healthcare professional for an accurate diagnosis and treatment options.
Ophiostomatales is an order of fungi in the class Sordariomycetes. It includes both plant and insect pathogens, as well as saprobes (organisms that live on dead or decaying organic matter). The order contains several genera that are important economically, including Ceratocystis and Ophiostoma, which contain species that cause diseases in trees such as Dutch elm disease and oak wilt. Members of this order produce asexual spores called conidia in specialized structures called conidiophores, and sexual spores called ascospores in ascus fruiting bodies. They are often found in sapwood and bark of trees, and can be disseminated by insect vectors or through the movement of wood products.
I'm sorry for any confusion, but "weevils" are not a medical term. They are small beetles, typically characterized by their elongated snouts. Some species are known to infest and damage crops such as grains, causing agricultural harm. If you have any questions related to medical terminology or health concerns, I'd be happy to help!
A larva is a distinct stage in the life cycle of various insects, mites, and other arthropods during which they undergo significant metamorphosis before becoming adults. In a medical context, larvae are known for their role in certain parasitic infections. Specifically, some helminth (parasitic worm) species use larval forms to infect human hosts. These invasions may lead to conditions such as cutaneous larva migrans, visceral larva migrans, or gnathostomiasis, depending on the specific parasite involved and the location of the infection within the body.
The larval stage is characterized by its markedly different morphology and behavior compared to the adult form. Larvae often have a distinct appearance, featuring unsegmented bodies, simple sense organs, and undeveloped digestive systems. They are typically adapted for a specific mode of life, such as free-living or parasitic existence, and rely on external sources of nutrition for their development.
In the context of helminth infections, larvae may be transmitted to humans through various routes, including ingestion of contaminated food or water, direct skin contact with infective stages, or transmission via an intermediate host (such as a vector). Once inside the human body, these parasitic larvae can cause tissue damage and provoke immune responses, leading to the clinical manifestations of disease.
It is essential to distinguish between the medical definition of 'larva' and its broader usage in biology and zoology. In those fields, 'larva' refers to any juvenile form that undergoes metamorphosis before reaching adulthood, regardless of whether it is parasitic or not.
I apologize for any confusion, but "Pinus" is not a medical term. It is the genus name for a group of plants commonly known as pine trees, which belong to the family Pinaceae in the kingdom Plantae. These evergreen coniferous resinous trees are widely distributed throughout the Northern Hemisphere, with some species also found in the Southern Hemisphere.
If you have any medical terms or concepts that you would like me to define or explain, please feel free to ask!
I must clarify that the term 'pupa' is not typically used in medical contexts. Instead, it is a term from the field of biology, particularly entomology, which is the study of insects.
In insect development, a pupa refers to a stage in the life cycle of certain insects undergoing complete metamorphosis. During this phase, the larval body undergoes significant transformation and reorganization within a protective casing called a chrysalis (in butterflies and moths) or a cocoon (in other insects). The old larval tissues are broken down and replaced with new adult structures. Once this process is complete, the pupal case opens, and the adult insect emerges.
Since 'pupa' is not a medical term, I couldn't provide a medical definition for it. However, I hope this explanation helps clarify its meaning in the context of biology.
I'm sorry for any confusion, but "Insect Proteins" is not a recognized medical term. However, I can provide some information about insect protein from a nutritional and food science perspective.
Insect proteins refer to the proteins that are obtained from insects. Insects are a rich source of protein, and their protein content varies by species. For example, mealworms and crickets have been found to contain approximately 47-63% and 60-72% protein by dry weight, respectively.
In recent years, insect proteins have gained attention as a potential sustainable source of nutrition due to their high protein content, low environmental impact, and the ability to convert feed into protein more efficiently compared to traditional livestock. Insect proteins can be used in various applications such as food and feed additives, nutritional supplements, and even cosmetics.
However, it's important to note that the use of insect proteins in human food is not widely accepted in many Western countries due to cultural and regulatory barriers. Nonetheless, research and development efforts continue to explore the potential benefits and applications of insect proteins in the global food system.
Oviposition is a medical/biological term that refers to the process of laying or depositing eggs by female organisms, including birds, reptiles, insects, and fish. In humans and other mammals, the term is not applicable since they give birth to live young rather than laying eggs.
