Domestic ducks in southern China act as an important reservoir for influenza viruses and have also facilitated the establishment of multiple H6 influenza virus lineages. can facilitate significant genetic and antigenic changes in viruses established in this host and highlight gaps in our knowledge of influenza virus ecology and even the evolutionary behavior of this virus family in its aquatic avian reservoirs. INTRODUCTION Aquatic birds are accepted as the natural reservoirs of influenza A viruses, and these viruses have been introduced to other animals, shaping the current ecology of influenza viruses (17). Alteration of the influenza virus ecosystem by the emergence of novel host species or marked changes in the size and structure of host populations can impact the behavior of virus evolution. The establishment of multiple influenza virus subtypes (H5N1, H6N1, and H9N2) in the poultry of southern D609 China provides the best example of this (4, 5, 20). Domestic ducks in China have ...

Identifying the viability of protein focuses on is among the preliminary measures of medicine discovery. developed directly into create a healing effect in another mobile pathway [1]. Typically, druggability was examined by co-crystalizing protein with organic solvents to expose feasible hydrophobic storage compartments [13]. This process eventually developed to the use of high-throughput screens and nuclear magnetic resonance (NMR) analysis of chemical fragment libraries [14]. In turn, hit rates were used like a metric for protein druggability. However, these methods were problematic as they experienced low level of sensitivity and high protein consumption [15]. Recent methods such as fragment-based NMR fluorescence assays work to conquer these problems [16]. Despite developments in NMR spectroscopy, experimental methods are still problematic in that their accuracies are directly linked to the fragment library being used. Negative results from drug targets are 4-Chlorophenylguanidine ...

Thyrotropin-releasing hormone (TRH) immunoreactivity occurs in high concentration within the rat prostate. Previous studies have shown that the immunoreactive species consists of more than one TRH-like tripeptide which cross-reacts in the TRH radioim
The effects of iontophoretically applied thyrotropin-releasing hormone (TRH) on cat retinal brisk-sustained (X) and brisk-transient (Y) ganglion cells were studied in the intact eye in vivo. Under photopic illumination we found a differential action of TRH on ON- and OFF-centre cells: the maintained activity and light response were suppressed in ON-centre cells and enhanced in OFF-centre cells. This was true for both brisk sustained (X) and brisk-transient (Y) cells. In contrast, TRH did not influence the ganglion cell discharge under scotopic stimulus conditions. These results indicate that TRH acts on neurons presynaptic to ganglion cells and these neurons are only active under photopic conditions. We suggest that a possible functional role of this specific action of TRH is in light adaptation. ...
This gene encodes a member of the thyrotropin-releasing hormone family. Cleavage of the encoded proprotein releases mature thyrotropin-releasing hormone, which is a tripeptide hypothalamic regulatory hormone. The human proprotein contains six thyrotropin-releasing hormone tripeptides. Thyrotropin-releasing hormone is involved in the regulation and release of thyroid-stimulating hormone, as well as prolactin. Deficiency of this hormone has been associated with hypothalamic hypothyroidism. [provided by RefSeq, May 2013 ...
The effects upon basal hormone levels and neuroendocrine responses of a weight reducing diet allowing 1200 kcal daily were determined in male and female volunteers. Thyrotropin (TSH) responses to thyrotropin-releasing hormone (TRH) were unchanged in men but attenuated in women; this effect was associated with a fall in basal TSH in women, not in men. Rates of non-suppression of cortisol in response to oral dexamethasone (1 mg) were unchanged during dieting although basal morning cortisol levels rose in males and females. The implications for the use of the TRH test and the dexamethasone suppression test (DST) in depressive illness are discussed.
A sensitive and specific radioimmnunoassay has been used to measure the distribution of thyrotropin-releasing hormone (TRH) in rat brain. All areas of brain tested, except cerebellum, contained readily measurable amounts of TRH. The hypothalamus contained only 31.2 percent of the total brain content of TRH. These results support recent suggestions of central actions for TRH in addition to its hypophysiotropic functions. ...

This report describes the extraction of synthetic TRH and its metabolic conversion in the perfused guinea pig placenta. These studies were performed to obtain an estimate of fractional fetal TRH losses through the placenta and to determine if some of these losses are due to TRH metabolism. The in situ guinea pig placenta was perfused through an umbilical artery for 90 min, and placental effluent fractions were collected at timed intervals from the umbilical vein. Experiments were performed in which the perfusion buffer contained 0.01, 1, and 10 micrograms/ml or no synthetic TRH. Synthetic TRH was always perfused in the presence of 3H2O. In experiments in which TRH was perfused, the perfusion reservoir contents and placental effluent fractions were counted for 3H, and TRH and deamido-TRH were determined by RIA. Similarly, cyclo(His-Pro) was measured when 10 micrograms/ml TRH were perfused. When no TRH was perfused, the perfusion reservoir and placental effluent contents were processed to determine their

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The activation of gene transcription is a multistep process that is triggered by factors that recognize transcriptional enhancer sites in DNA. These factors work with co-activators to direct transcriptional initiation by the RNA polymerase II apparatus. The protein encoded by this gene is a subunit of the CRSP (cofactor required for SP1 activation) complex, which, along with TFIID, is required for efficient activation by SP1. This protein is also a component of other multisubunit complexes e.g. thyroid hormone receptor-(TR-) associated proteins which interact with TR and facilitate TR function on DNA templates in conjunction with initiation factors and cofactors. It also regulates p53-dependent apoptosis and it is essential for adipogenesis. This protein is known to have the ability to self-oligomerize. [provided by RefSeq, Jul 2008 ...

A number of clonal cell lines derived from a rat pituitary tumour, collectively termed GH cells, have retained a range of differentiated cell functions, including their ability to secrete the hormones prolactin and growth hormone in response to stimuli such as thyrotropin-releasing hormone (TRH). The mechanisms underlying this release process involve, at least in part, an increase in cytosolic free calcium levels, and the cells have proved useful as a model system in studies of receptor-controlled calcium mobilization. The initial response of the cells to the addition of TRH now appears to be the interaction of the occupied TRH receptor with a GTP-binding protein. A sophisticated signalling system is then activated which initially involves the phosphodiesteratic hydrolysis of phosphatidylinositol 4,5-bisphosphate to 1,2-diacylglycerol and inositol 1,4,5-trisphosphate. Both of these products are important intracellular messengers, and their formation leads to a plethora of biochemical and ...
Abstract: We have reported a highly cooperative interaction between leptin and thyrotropin releasing hormone (TRH) in the hindbrain to generate thermogenic responses (Hermann et al., 2006) (Rogers et al., 2009). Identifying the locus in the hindbrain where leptin and TRH act synergistically to increase thermogenesis will be necessary before we can determine the mechanism(s) by which this interaction occurs. Here, we performed heat-induced epitope recovery techniques and in situ hybridization to determine if neurons or afferent fibers in the hindbrain possess both TRH type 1 receptor and long-form leptin receptor [TRHR1; LepRb, respectively]. LepRb receptors were highly expressed in the solitary nucleus [NST], dorsal motor nucleus of the vagus [DMN] and catecholaminergic neurons of the ventrolateral medulla [VLM]. All neurons that contained LepRb also contained TRHR1. Fibers in the NST and the raphe pallidus [RP] and obscurrus [RO] that possess LepRb receptors were phenotypically identified as ...

is one such condition which is affected highly by the imbalance of hormones. Testosterone is one of those hormones. Increase in testosterones (male hormone) inside females causes the reproductive system to become infertile along with the development of multiple cysts in the ovaries. This worsens the condition of PCOS.. Thus, hypothyroidism gives rise to PCOS inside females. It has been seen that thyroid disorders and polycystic ovary syndrome (PCOS) are two of the most common endocrine disorders in the general population.. WHAT COULD BE THE REASON BEHIND DEVELOPMENT OF PCOS DUE TO HYPOTHYROIDISM?. One reason has been given that increase in testosterone levels causes PCOS in hypothyroid-affecting females.. Another reason is the rise in thyrotropin-releasing hormone (TRH). Rise in thyrotropin-releasing hormone (TRH) in primary hypothyroidism leads to increased prolactin and thyroid stimulating hormone (TSH). Prolactin contributes toward polycystic ovarian syndrome by inhibiting ovulation as a ...

In rat paraventricular thalamic nucleus (PVT) neurons, activation of thyrotropin releasing hormone (TRH) receptors enhances neuronal excitability via concurrent decrease in a GIRK-like conductance and opening of a cannabinoid receptor-sensitive transient receptor potential canonical (TRPC)-like conductance. Here we investigated the calcium (Ca2+) contribution to the components of this TRH-induced response. TRH-induced membrane depolarization was reduced in the presence of intracellular BAPTA, also in media containing nominally zero [Ca2+]o, suggesting a critical role for both intracellular Ca2+ release and Ca2+ influx. TRH-induced inward current was unchanged by T-type Ca2+ channel blockade, but was decreased by blockade of high-voltage-activated Ca2+ channels (HVACCs). Both the pharmacologically isolated GIRK-like and the TRPC-like components of the TRH-induced response were decreased by nifedipine and increased by BayK8644, implying Ca2+ influx via L-type Ca2+ channels. Only the TRPC-like ...

Roger Charles Louis Guillemin (rođen 11. siječnja, 1924. u Dijonu, Francuska) je američko-francuski liječnik koji je 1977.g. dobio Nobelovu nagradu za fiziologiju ili medicinu za svoj rad na neurohormonima. Guillemin je diplomirao medicinu 1949.g. u Lyonu, i nakon toga preselio u Montréal, u Kanadi, da bi 1953.g. preselio u SAD. Godine 1965.g. postao je naturalizirani građanin SADa. Potkraj 1950ih, Guillemin i Andrew V. Schally uspjeli su, neovisno jedan od drugoga, u svojim labaratorijima, iz hipotalamus ovce i svinje, izdvojiti neke tvari, koje su u tkivu hipofize dovele do izlučivanja hormona te žlijezde. Jedna je tvar uzrokovala otpuštanje ACTH, druga otpuštanje TSH, a treća otpuštanje LH i FSH. Nazvali su te tvari oslobađajući faktori, RF (prema engl. releasing factor) ili RH (prema engl. releasing hormon).
