To write:
The description for the negative feedback which down-regulates the signals which are induced by erythropoietin.
Introduction:
Erythropoietin (Epo) is a hormone that is released by the kidneys. It increases the red blood cells production rate in response to the reducing levels of oxygen in the human tissues. Cytokine receptor is linked with a JAnus Kinase (JAK kinase). Src homology region 2 domain-containing phosphatase-1 (SHP-1) are the signaling molecules which control a diversity of cellular processes together with differentiation, mitotic cycle, cell growth, and oncogenic transformation. Suppress or of cytokine signaling 3 (SOCS protein).
(b)
To write:
The description for the negative feedback which down-regulates the signals which are induced by TGF-β.
Introduction:
Transforming growth factor beta or TGF-β is a cytokine which is multifunctional. It belongs to the superfamily of transforming growth factor. It consists of four dissimilar isoforms like TGF-β (1 to 4) represented as TGFβ1, TGFβ2, TGFβ3, TGFβ4. This growth factor family also contain many other signaling proteins that are produced by all lineages of white blood cell. TGF-β receptor I show activation of Smad2 and Smad3. These Smad2 and Smad3 are the proteins which form a hetero-oligomer with Smad4. Ski and SnoN are the functionally and structurally highly homologous proteins.
