JAK/STAT Signaling Pathway Inhibitors

The Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway is a critical signaling cascade for mediating cytokine receptor-derived signals. JAK/STAT signaling contributes to the regulation of haematopoietic cell survival, proliferation and differentiation. Also, this signaling pathway is involved in the developmental process, growth regulation and maintenance of homeostasis in other cells and tissues. The JAK/STAT signaling pathway is made up of four JAKs (JAK1-3, and Tyk2) and seven STAT proteins (STAT1-4, 5A, 5B and 6).

Initiation of JAK/STAT signaling proceeds as a result of cytokine receptors activating a specific set of individual JAKs and STATs that is dependent on the characteristics of the intracellular domains of the receptor chains. The binding of cytokines to transmembrane receptors (i.e. interleukin-2 or interferon) results in cross-activation of receptor-associated JAKs by tyrosine phosphorylation due to receptor dimerization and reorganization events. Activated JAKs lead to the phosphorylation of tyrosine residues in the cytoplasmic domain that increases their catalytic activity for STAT proteins. JAKs mediate phosphorylation on the C-terminus. This in turn causes STAT proteins to dissociate from the receptor, dimerize (mediated by Src-homology-2 domains) and translocate to the cell nucleus where they induce gene transcription of intracellular regulators of cell proliferation (cyclins and Myc) and survival (Bcl family). Regulating the JAK/STAT signaling pathway are SOCS1, SOCS3 and PIAS3. Constitutive signaling of the JAK/STAT pathway, high levels of STAT3 proteins and/or deminished function of negative regulators can contribute to tumour initiation and progression events.
