Thyrotropin releasing hormone effects
Webb17 mars 2024 · In contrast, CK1α activation weakened TSH stimulation by thyrotropin-releasing hormone (TRH) by suppressing protein kinase C (PKC)/extracellular signal-regulated kinase (ERK)/cAMP response ... TSH (with a half-life of about an hour) stimulates the thyroid gland to secrete the hormone thyroxine (T4), which has only a slight effect on metabolism. T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism. About 80% of this conversion is in the liver and other organs, and 20% in the thyroid itself. TSH is secreted throughout life but particularly reaches high levels during the periods of rapid gr…

The body has a complex network of feedback loops that helps to maintain homeostasis. For example, the hypothalamus in the brain produces the hormone thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to produce …
Side effects after intravenous TRH administration are minimal. Nausea, flushing, urinary urgency, and mild rise in blood pressure have been reported. [14] After intrathecal administration, shaking, sweating, shivering, restlessness, and mild rise in blood pressure were observed.
