Insights

SIAH2 acts as an oncogene in colorectal cancer (CRC), promoting tumor growth and metastasis. Its activity is linked to the PI3K/AKT pathway, offering potential new therapeutic targets for CRC treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Colorectal cancer (CRC) is a leading cause of cancer death with a poor prognosis.
  • SIAH E3 Ubiquitin Protein Ligase 2 (SIAH2) influences protein expression through ubiquitination and proteasome degradation.
  • The specific role of SIAH2 in CRC development has been unclear.

Purpose of the Study:

  • To investigate the role of SIAH2 in colorectal cancer progression.
  • To elucidate the molecular mechanisms by which SIAH2 affects CRC.
  • To identify potential therapeutic strategies targeting SIAH2 in CRC.

Main Methods:

  • In vivo and in vitro experiments were conducted.
  • Cell proliferation, migration, invasion, and colony formation assays were performed.
  • Analysis of the PI3K/AKT signaling pathway and PTEN loss was carried out.

Main Results:

  • SIAH2 was identified as an oncogene in colorectal cancer.
  • SIAH2 significantly enhanced CRC cell proliferation, migration, invasion, and colony formation.
  • SIAH2 promoted the PI3K/AKT signaling pathway, with PTEN loss regulating this activation.

Conclusions:

  • SIAH2 plays a crucial role in promoting colorectal cancer progression.
  • Targeting SIAH2 and its associated PI3K/AKT pathway may offer new therapeutic avenues for CRC.
  • Understanding the SIAH2-PTEN-PI3K/AKT axis provides novel insights into CRC tumorigenesis.

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
