A Signaling Network of Thyroid-Stimulating Hormone


Introduction. Thyroid-stimulating hormone (TSH) is synthesized and secreted by the anterior lobe of the pituitary gland. TSH acts on thyroid follicular epithelium and triiodothyronine (T3) and thyroxine (T4) hormones regulate the synthesis and release of TSH at the pituitary level and indirectly affect TSH production by their effect on TRH.

Insulin signal transduction pathway - Wikipedia


The insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis.This pathway is also influenced by fed versus fasting states, stress levels, and a variety of other hormones.. When carbohydrates are consumed, digested ...

Signal Transduction: Definition, Pathways, Examples ...


Signal transduction is the process of transferring a signal throughout an organism, especially across or through a cell. Signal transduction relies on proteins known as receptors, which wait for a chemical, physical, or electrical signal. Chemical signals are called ligands, and can be produced by organisms to control their body or received from the environment. Regardless of which type of signal, it must be transferred throughout t…
