unusual facts about Secretion



Arthur Robertson Cushny

He was also interested for several years in the physiological action of optical isomers and, in c. 1900, the mechanisms of kidney secretion, providing three advanced papers on the subject between 1901 and 1904 in the Journal of Physiology.

Bacterial small RNA

The 6S RNA binds to RNA polymerase and regulates transcription, tmRNA has functions in protein synthesis, including the recycling of stalled ribosomes, 4.5S RNA regulates signal recognition particle (SRP), which is required for the secretion of proteins and RNase P is involved in maturing tRNAs.

Cimetidine

Cimetidine was the culmination of a project at Smith, Kline and French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist to suppress stomach acid secretion.

Circumventricular organs

For example, it is thought that the OVLT may also play a role in the regulation of LH secretion via a negative feedback mechanism.

Copper peptide GHK-Cu

Even though an exact mechanism remains unclear, in a recent study GHK and its copper complexes decreased TNF-alpha-dependent IL-6 secretion in normal human dermal fibroblasts.

Development of endocrine system

This stage is regulated by the secretion of insulin-like 3 (INSL3), a relaxin-like factor produced by the testicles, and the INSL3 G-coupled receptor, LGR8.

Effective arterial blood volume

The kidney mechanisms used to restore EABV include, (1) sympathetic nerve activity; (2) Atriopeptin (ANP) secretion from the atria; (3) Starling forces; (4) Renin-angiotensin-aldosterone system.

Entero-oxyntin

Entero-oxyntin is a hormone released from intestinal endocrine cells which stimulates gastric acid secretion in the stomach.

Enterobactin

Iron deficiency in bacterial cells triggers secretion of enterobactin into the extracellular environment, causing formation of an coordination complex "FeEnt" wherein ferric ion is chelated to the conjugate base of enterobactin.

Ffn

Fetal fibronectin protein or its assay from vaginal secretion to assess risk of premature delivery

Granzyme

Granzyme secretion can be detected and measured using Western Blot or ELISA techniques.

Heat-labile enterotoxin

In addition to its effects on chloride secretion, which involve the same steps as the effects of cholera toxin, heat-labile enterotoxin binds additional substrates: lipopolysaccharide on the surface of E. coli cells and A-type blood antigens.

Hyperchloremic acidosis

Renal tubular acidosis failure of HCO3- resorption(i.e., proximal renal tubular acidosis, or overdose of carbonic anhydrase inhibitor) or failure of H+ secretion (i.e. in distal renal tubular acidosis)

Iberogast

Named after the genus (Iberis) of one of its ingredients, it is also claimed to possess anti-inflammatory, antioxidative and free radical-inhibiting properties as well as reduce gastric acid secretion.

Insulin signal transduction pathway and regulation of blood glucose

Insulin secretion mechanism is a common example of Signal transduction pathway mechanism.

Isolated hypogonadotropic hypogonadism

Other causes of IHH include GnRH insensitivity, which is the second most common cause of IHH and is thought to be responsible for up to 20% of cases, and a minority (less than 5-10%) due to inactivating mutations in a variety of other genes which positively regulate GnRH secretion such as CHD7, KISS1R, and TACR3.

Jean-Pierre Lecocq

Under his leadership secretory and non-secretory expression systems for the production of recombinant proteins in E. coli, Saccharomyces cerevisiae, Baculovirus and mammalian cells in cell culture were developed and recombinant virus technology was established.

Limb bud

FGF10 = Initially, Tbx proteins induce secretion of FGF10 by cells in the lateral plate mesoderm.

Lubiprostone

Lubiprostone is a bicyclic fatty acid derived from prostaglandin E1 that acts by specifically activating ClC-2 chloride channels on the apical aspect of gastrointestinal epithelial cells, producing a chloride-rich fluid secretion.

Nicoya

To give just one example, tribute in Nicoya was traditionally paid by one product that could be produced nowhere else in the region: cotton thread dyed purple with the secretion of a rare mollusk found on the Pacific Coast of the genus Murex.

Polyergus rufescens

She emits a secretion from the Dufour's gland on her abdomen, named after its discoverer, Léon Jean Marie Dufour, which includes a pheromone which subdues the attacked ants and makes them less aggressive.

Thromboregulation

The binding of platelets to the sub-endothelial collagen stimulates the secretion of ADP, TXA2, and serotonin present in the platelet granules.

Uvea

In addition some uveal regions have special functions of great importance, including secretion of the aqueous humour by the ciliary processes, control of accommodation (focus) by the ciliary body, and optimisation of retinal illumination by the iris's control over the pupil.

Varnish

The source of shellac resin is a brittle or flaky secretion of the female lac insect, Kerria lacca, found in the forests of Assam and Thailand and harvested from the bark of the trees where she deposits it to provide a sticky hold on the trunk.

Zymology

The German Eduard Buchner, winner of the 1907 Nobel Prize in chemistry, later determined that fermentation was actually caused by a yeast secretion that he termed zymase.
