There are three major types of cells in fruit fly (and mammalian) intestines: Stem cells, hormone-producing cells, and nutrient-handling cells. Think of the stem cells as blanks, which are eventually programmed to become either hormone-producing or nutrient-handling cells. The authors discovered that this programming can be influenced by dietary nutrients, and that young animals are particularly sensitive to these changes.. Obniski, the lead author, and her colleagues found that changes in dietary cholesterol particularly alter the cellular programming driving the production of new specialized cells from stem cells.. The effect of cholesterol is to promote the programming of more new, blank cells into hormone-producing cells rather than nutrient-handling cells. Conversely, decreasing dietary cholesterol results in more nutrient-absorbing cells and fewer hormone-producing cells.. Moreover, the researchers were able to identify the detailed molecular mechanism by which cholesterol causes these ...

Streptozotocin diabetes in rats is associated with reduced function of the hypothalamo-pituitary-thyroid axis. The structure and hormone secretion of the thyroid and pituitary glands were studied in adult male rats 1 month after streptozotocin injection. The thyroid of diabetic rats was characterized by decreased follicle area and epithelial thickness. By electron microscopy, thyroid epithelial cells were characterized by flattened and almost empty rough endoplasmic reticulum cisternae, scanty exocytotic apical and endocytotic vesicles as well as degenerate mitochondria and rough endoplasmic reticulum. By immunohistochemistry, intracolloidal thyroglobulin and T3 as well as intraepithelial thyroglobulin were reduced. Electron microscopic and immunohistochemical analysis of pituitary glands showed that in diabetic rats thyrotrophs were mostly of type II, and the number of thyrotrophs (type I + type II) was greater than in controls. By radioimmunoassay (RIA), plasma T3, T4, and TSH levels

Stem cells of the primordium of the anterior pituitary, the Rathkes Pouch, give rise to all of the hormone-producing cell types in this tissue. During adulthood, when the organ reaches homeostasis, there is a requirement to replenish hormone-producing cells and to expand the populations depending on hormonal demand e.g. during pregnancy. We have shown that stem cells, expressing the transcription factor SOX2, are capable of generating new cells throughout life. The mechanisms that regulate the size of the stem cell pool and instruct proliferation and commitment are poorly understood. We are studying the signaling mechanisms controlling these processes in the mouse. ...

TY - JOUR. T1 - Pharmacokinetics and Pharmacodynamics of Oral Pergolide Mesylate In Horses With Pituitary Pars Intermedia Dysfunction. AU - Rendle, D.I.. AU - Doran, Gregory. AU - Ireland, J.L.. AU - Edwards, Scott. PY - 2017/8/31. Y1 - 2017/8/31. N2 - Reasons for performing study: The pharmacokinetics and pharmacodynamics of pergolide in horses are poorly understood. Objectives: Investigate pharmacokinetic and pharmacodynamic properties of orally administered pergolide in horses with pituitary pars intermedia dysfunction (PPID). Study design: Cohort study. Methods: Six horses with PPID received 4 μg/kg oral pergolide for 18 days. Samples were collected 0.5 h before and 2 and 12 h after administration of pergolide daily for 18 days and plasma pergolide and adrenocorticotropic hormone (ACTH) concentrations were determined. Results: Maximum plasma concentrations after the first oral dose of pergolide (0.104-0.684 ng/mL; mean 0.308 ± 0.201 ng/mL) were not significantly different to the maximum ...

The hippocampus projects to the anterior thalamic nuclei both directly and indirectly via the mammillary bodies, but little is known about the electrophysiological properties of these convergent pathways. Here we demonstrate, for the first time, the presence of long-term plasticity in anterior thalamic nuclei synapses in response to high- and low-frequency stimulation (LFS) in urethane-anesthetized rats. We compared the synaptic changes evoked via the direct vs. the indirect hippocampal pathways to the anterior thalamus, and found that long-term potentiation (LTP) of the thalamic field response is induced predominantly through the direct hippocampal projections. Furthermore, we have estimated that that long-term depression (LTD) can be induced only after stimulation of the indirect connections carried by the mammillothalamic tract. Interestingly, basal synaptic transmission mediated by the mammillothalamic tract undergoes use-dependent, BDNF-mediated potentiation, revealing a distinct form of ...

Fortunately there is an effective treatment available for the treatment of Cushings Syndrome. This is a drug called pergolide, available in a licensed form as Prascend. Pergolide reduces the production of ACTH by the pituitary gland. After 2-4 weeks of treatment we repeat the blood test to measure the level of ACTH in order to ensure we are providing the correct dose of pergolide. The most common side effect of pergolide is a decrease in appetite following initiation of treatment. This is almost always reversible and when it does occur, we normally reduce the dose of pergolide and the appetite returns. ...

Two important top features of amphibian metamorphosis are the sequential response of tissues to different concentrations of thyroid hormone (TH) and the development of the negative feedback loop between the pituitary and the thyroid gland that regulates TH synthesis by the thyroid gland. the cells that express proopiomelanocortin. Physiological concentrations of T3 but not T4 can suppress thyrotropin subunit gene expression. The timing and the remarkable specificity of D2 expression in the thyrotrophs of the Rabbit Polyclonal to ARX anterior pituitary coupled with the requirement for locally synthesized T3 strongly support a role for D2 in the onset of the negative feedback loop at the climax 1276105-89-5 manufacture of metamorphosis. The metamorphosis of anurans is controlled by a steadily increasing concentration of thyroid hormone (TH) in tadpoles. TH reaches a peak at the climax of metamorphosis and then falls as the final change, tail resorption, occurs (1, 2). This gradual increase in TH ...

Backround: A normal thyroid function is critical for metabolism, well-being and cognitive function. It is now well accepted that primary subclinical hypothyroidism, characterized by normal circulating thyroid hormones (fT3 and fT4) and elevated TSH, should be treated to improve reduced quality of life and abnormalities of lipid metabolism. In central hypothyroidism (CH) the dose of replacement therapy aims to achieve normal thyroxin (T4) concentrations as defined by appropriate reference populations. Adequate thyroxin treatment is especially challenging, as T4 cannot be titrated according to endogenous TSH levels because of the impaired hypothalamic-pituitary unit. The majority of untreated CH patients show normal (40 %) or elevated TSH levels (35 %) while only a minority has reduced concentrations (25 %) {Faglia, 1979 #1}. These findings are explained by the lack of pulsatile secretion and nocturnal TSH surge, which has been attributed to impaired thyrotroph function in CH patients {Caron, 1986 ...

While PPID is not curable, medical management and meticulous husbandry are recommended to reduce the signs and symptoms associated with this disorder. An integral part of PPID management is medical treatment. The most widely used drug is the brand name veterinary product Prascend®. It helps decrease some of the hormone production by the pituitary gland. Several studies have shown that Prascend®-treated horses have significant improvements in hair coat, frequency of urination/drinking, frequency of infections and laminitis bouts, and many laboratory test results. The drug is prescribed for once daily administration.. Another drug, which may be useful in treatment of PPID, is cyproheptadine. Studies suggest that cyproheptadine is not as effective in improving PPID symptoms compared to Prascend®. However, it may aid those animals with minimal response to Prascend® alone. A combination of both drugs is occasionally recommended.. Over time, the amount of drug your horse requires to manage this ...

A chromophil biological cell is a cell which is easily stainable by absorbing chromium salts used in histology to increase the visual contrast of samples for microscopy. Chromophil cells are mostly hormone-producing cells containing so-called chromaffin granules. In these subcellular structures, amino acid precursors to certain hormones are accumulated and subsequently decarboxylated to the corresponding amines, for example epinephrine, norepinephrine, dopamine or serotonin. Chromophil cells therefore belong to the group of APUD (amine precursor uptake and decarboxylation) cells. These cells are scattered throughout the whole body, but particularly in glands such as the hypothalamus, hypophysis, thyroid, parathyroid and pancreas ...

These therapies are used alone or in combination.. The carcinoid. The carcinoid is a so-called neuroendocrine tumor. It is based on hormone-producing cells in the gastrointestinal tract or other organs. Carcinoids are most common in the cecum or small intestine. Affected suffer from hot flashes, palpitations, abdominal pain and diarrhea. In order to diagnose the small intestine carcinoid, certain hormones and their degradation products must be detected in the blood.. Carcinoid can be treated in the same way as other small intestinal tumors: surgery, chemo- and / or radiotherapy. In addition, can also be treated with drugs that inhibit hormone production.. ...

AU - Il Jee, Soo. AU - Kim, Sun Ho. AU - Lee, Eun Jig. PY - 2019/4/1. Y1 - 2019/4/1. N2 - Purpose: The molecular mechanisms underlying tumor growth in Cushings disease (CD) still remain a challenge. Moreover, clinical manifestations of CD may vary depending on hormonal activity; however, factors involved in the hormonal aggressiveness of adrenocorticotropic hormone (ACTH)-secreting pituitary tumors have not been fully clarified. We investigated the association between the expression of cellular markers regarding pituitary tumor progression and initial or postoperative hormone levels in patients with CD. Methods: Tumor tissues from 28 corticotroph adenomas (female 26, male 2, mean age 39.21 ± 10.39 years) were subject to immunohistochemical study using the following antibodies: pituitary tumor-transforming ...

Thyroid-stimulating hormone (also known as thyrotropin, or TSH) is a hormone which stimulates the thyroid gland. The thyroid gland secretes thyroid hormones, which control how fast the bodys chemical functions go (the metabolic rate). Thyroid hormones influence the metabolic rate in two ways: by stimulating almost every tissue in the body to produce proteins and by increasing the amount of oxygen that cells use. Thyroid hormones affect many vital body functions.[1] Thyrotropin is a glycoprotein hormone synthesized and secreted by thyrotrope cells in the anterior pituitary gland, which adjusts the endocrine function of the thyroid gland.[1][2][3] ...

Biochemistry. Moderate to marked hypertriglyceridaemia most likely reflected primary or secondary hyperlipaemia. Equine hyperlipaemia is a consequence of a negative energy status which in this case was most likely secondary to anorexia, obesity or hepatopathy. Other causes of secondary hyperlipaemia were less likely (stress, neoplasia, gastrointestinal disease, pituitary pars intermedia dysfunction [PPID]) or were ruled out (laminitis, renal failure, dental disease, endotoxaemia).. CK was markedly elevated indicating myocyte injury (mostly likely skeletal but also cardiac) which could be secondary to lipid accumulation, intramuscular injections or hypoxia. Nutritional causes, toxicity, trauma, rhabdomyolysis, inflammatory and infectious diseases were considered unlikely causes of muscle injury based on the clinical picture.. Moderate elevation of AST could reflect myocyte and/or hepatic injury - supported by increases in CK and GGT.. GGT was markedly elevated which indicated hepatobiliary ...

Stomach, or gastric, cancer is a cancer that starts from the lining of the stomach wall. The stomach is located in the upper abdomen, and begins the process of digesting the food we eat into nutrients the body can use. The most common form of stomach cancer, gastric adenocarcinoma, is found in approximately 20,000 people in the United States per year, typically in people older than 65. Males are more likely to get this cancer than women. Gastric adenocarcinoma is much more common in other parts of the world, particularly in Asia and South America, possibly due to lifestyle and environmental factors. Other, less common, types of stomach cancer include lymphoma, gastrointestinal stromal tumors (GIST, cancer of the muscle or connective tissue of the stomach wall), and carcinoid tumors (cancer of the hormone-producing cells of the stomach).. ...

The aging in men is accompanied by an increase in the presence of connective tissue in all the organs and tissues, and with increase of corticotrophs and folliculostellate cells in adenohypophysis, which can affect the function of the HPA axis in healthy elderly individuals. Objective of the research was to perform quantification of structural changes during aging (cellularity, presence of the connective tissue and blood flow), collagen type IV, corticotrophs and folliculostellate cells on the pituitary tissue, obtained at autopsy, using histochemical, immunohistochemical and morphometric methods. Histochemical part of the research showed an increase of the cell size that occured during normal aging in the adenohypophysis. The analyzed cells of the adenohypophysis were significantly larger and, at the same time, they were characterized by a substantially more regular shape in female in comparison to the male patients cases. Differences in the cellular composition of the pituitary ...
