Tsh pathway
WebMeasurement of TSH is a screening test for suspected thyroid dysfunction. TSH release from the anterior pituitary is tightly controlled by a negative feedback loop from the circulating thyroid hormones thyroxine (T4) and triiodothyronine (T3). A small rise in thyroid hormone production leads to a logarithmic suppression of TSH, and vice versa ...

WebThe cJun N-terminal kinase (JNK) signaling pathway is a key mediator of metabolic stress responses caused by consuming a high-fat diet, including the development of obesity. To test the role of JNK, we examined diet-induced obesity in mice with targeted ablation of Jnk genes in the anterior pituitary gland. These mice exhibited an increase in ...

WebSep 20, 2024 · To explore where in the TSH signaling pathway ghrelin could cause its influence, we measured the concentration of cAMP in the cultures with or without ghrelin. This particular component is relevant because the TSH receptor is G αs coupled [ 57 ] and therefore induces cAMP expression when activated in contrast to the GhrR which is G αq … WebApr 13, 2024 · Here, we propose that GD and HT have the same fundamental origin: both diseases are the cost of a beneficial physiological process called autoimmune surveillance of hypersecreting mutants. Autoreactive T cells selectively eliminate mutant cells that hypersecrete the hormones and threaten to become toxic nodules.
