The JAK-STAT signaling pathway is a chain of interactions between proteins in a cell, and is involved in processes such as immunity, cell division, cell death, and tumor formation. The pathway communicates information from chemical signals outside of a cell to the cell nucleus , resulting in the activation of genes through the process of ...
STAT3 can promote oncogenesis by being constitutively active through various pathways as mentioned elsewhere. A tumor suppressor role of STAT3 has also been reported. [ 23 ] [ 24 ] [ 25 ] In the report on human glioblastoma tumor, or brain cancer, STAT3 was shown to have an oncogenic or a tumor suppressor role depending upon the mutational ...
Dysregulation of this pathway is frequently observed in primary tumors and leads to increased angiogenesis which enhances the survival of tumors and immunosuppression. Gene knockout studies have provided evidence that STAT proteins are involved in the development and function of the immune system and play a role in maintaining immune tolerance ...

Signal transducer and activator of transcription 5 (STAT5) refers to two highly related proteins, STAT5A and STAT5B, which are part of the seven-membered STAT family of proteins. Though STAT5A and STAT5B are encoded by separate genes , the proteins are 90% identical at the amino acid level. [ 1 ]
STAT6-mediated signaling pathway is required for the development of T-helper type 2 (Th2) cells and Th2 immune response. [8] Expression of Th2 cytokines, including IL-4, IL-13, and IL-5, was reduced in STAT6-deficient mice. [5] STAT 6 protein is crucial in IL4 mediated biological responses.
Janus kinase (JAK) is a family of intracellular, non-receptor tyrosine kinases that transduce cytokine-mediated signals via the JAK-STAT pathway.They were initially named "just another kinase" 1 and 2 (since they were just two of many discoveries in a PCR-based screen of kinases), [1] but were ultimately published as "Janus kinase".
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
