چکیده

Chronic liver injury, liver fibrosis and formation of hepatocellular carcinoma are intimately linked and represent a major medical challenge since treatment options are limited. Therefore, it is important to identify cellular and molecular pathways that promote liver damage or provide hepatoprotection for development of therapeutic approaches. Recently, the transcription factors STAT3 and STAT5 have been implicated in liver fibrosis induced by cholestatic liver damage. In this review, we summarize our current knowledge about STAT proteins in liver fibrosis and focus on common activities that underlie the hepatoprotective mechanisms regulated by IL-6/gp130/STAT3 and GH/STAT5/IGF-1 signaling pathways.

The Jak-Stat Signaling Pathway of Interferons System: Snapshots

Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...

Effect of valproic acid on JAK/STAT pathway, SOCS1, SOCS3, Bcl-xL, c-Myc, and Mcl-1 gene expression, cell growth inhibition and apoptosis induction in human colon cancer HT29 cell line.

Background and aim: Cytokines are a large family of protein messengers. These proteins induce various cellular responses. Janus kinases (JAKs) are mediators of cytokine, activated JAKs phosphorylate signal transducers, and activators of transcription (STAT) proteins that regulate cell differentiation, proliferation, and apoptosis. Aberrant JAK/STAT signaling is involved in the oncogenesis of se...

Effects of matrine on JAK-STAT signaling transduction pathways in bleomycin-induced pulmonary fibrosis.

The current study aims to investigate the effects of matrine on the JAK-STAT signaling transduction pathways in bleomycin (BLM)-induced pulmonary fibrosis (PF) and to explore its action mechanism. A total of 72 male C57BL/6 mice were randomized into the control, model, and treatment groups. PF models were established by instilling BLM intratracheally. The treatment group was given daily matrine...

Socs3

The suppressors of cytokine signaling (SOCS) family of proteins are cytokine-inducible inhibitors of Janus kinase (JAK)-signal transducer and activator of the transcription (STAT) signaling pathways. Among the family, SOCS1 and SOCS3 potently suppress cytokine actions by inhibiting JAK kinase activities. The generation of mice lacking individual SOCS genes has been instrumental in defining the ...

Targeted blockade of JAK/STAT3 signaling inhibits proliferation, migration and collagen production as well as inducing the apoptosis of hepatic stellate cells.

Protein tyrosine kinases belonging to the Janus kinase (JAK) family are associated with many cytokine receptors, which, on ligand binding, regulate important cellular functions such as proliferation, apoptosis and differentiation. The protective effects of JAK inhibitors on fibrotic diseases such as myelofibrosis and bone marrow fibrosis have been demonstrated in previous studies. The JAK inhib...
