一般描述
JAK (Janus kinases) are activated when cytokines bind with their receptors, upon which they phosphorylate the receptors and produce docking sites for signaling molecules. One of the main signaling molecules includes signal transducer and activator of transcription (Stat) family. JAK1 is needed by multiple cytokines, including the family using the shared receptor subunit called common γ chain (γc), such as interleukin (IL)-2, IL-4, IL-7, IL-9, IL-15 and IL-21. JAK1 KO (knockout) mice have early postnatal lethal or perinatal lethal phenotype due to neurological defects. In vitro studies show that JAK1S703I mutation functions as an activator of JAK-STAT pathways even in the absence of cytokines, and drives cellular proliferation. JAK1S703I mutant patient-derived xenograft (PDX) HCC (hepatocellular carcinoma) cells also show sensitivity to JAK1/2 inhibitor, ruxolitinib.
