Jak-STAT pathway

[′jak‚stat ′path‚wā]
(cell and molecular biology)
A rapid signal transduction pathway used by a variety of cytokines and growth factors to alter gene expression. Binding of a cytokine or growth factor to its receptor activates Jak (janus kinase—a cytoplasmic tyrosine kinase) and triggers it to phosphorylate and stimulate STAT (signal transducers and activators of transcription—a gene regulatory protein) to travel to the nucleus and induce transcription of a specific gene.

Research indicates that inhibiting the JAK-STAT signaling pathway induces anagen and subsequent hair growth, but activating STAT 5 in the dermal papilla is also important to induce the growth phase of the hair follicle, according to Dr.
On the other hand, SOX2 regulates the expression of STAT3 through JAK-STAT signaling pathway.
The JAK-STAT signaling pathway transmits information from chemical signals outside the cell, through the cell membrane, and into gene promoters on the DNA in the cell nucleus, which causes DNA transcription and activity in the cell (4).
Chemokine signaling pathway, cytokine-cytokine receptor interaction, and the JAK-STAT signaling pathway represented more than 50% of up-regulated transcripts in TCDD-treated and PCB-126-treated cells (Figure 1 A, B).
Evidence also suggests that A[beta] inhibits the JAK-STAT signaling pathway, thus potentially inhibiting IGF-1 expression.
These gene mutations result in stable activation of the JAK-STAT signaling pathway and lead to megakaryocytic hyperplasia and thrombocytosis.
