Insights

The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is crucial for immune responses and other cellular processes. This review explores its broad biological roles and involvement in human diseases, particularly cancers.

Area of Science:

  • Cellular signaling pathways
  • Immunology
  • Molecular biology

Background:

  • The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway was initially identified as central to interferon signaling.
  • Its role has expanded to include the mediation of numerous immune and non-immune signals.

Purpose of the Study:

  • To provide a synopsis of the biological and clinical significance of the JAK-STAT signaling pathway.
  • To highlight the importance of JAK-STAT signaling in various biological contexts.

Main Methods:

  • Review of existing literature on the JAK-STAT pathway.
  • Analysis of data from murine knockout models.
  • Examination of human diseases associated with JAK-STAT pathway dysfunction.

Main Results:

  • The JAK-STAT pathway is involved in a wide array of cellular communication processes beyond interferon signaling.
  • Murine models demonstrate the essential biological functions of this pathway.
  • Dysregulation of the JAK-STAT pathway is implicated in the pathogenesis of several human diseases, especially neoplastic conditions.

Conclusions:

  • The JAK-STAT pathway is a fundamental signaling system with broad biological implications.
  • Understanding JAK-STAT pathway function is critical for comprehending normal physiology and disease pathogenesis, particularly in cancer.

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
