Cancer-Critical Genes II: Tumor Suppressor Genes

8.3K
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.

Targeted Cancer Therapies

7.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Genetics

Background:

  • Signal transducer and activator of transcription 3 (STAT3) is a key transcription factor involved in cellular processes.
  • STAT3 regulates gene expression impacting development, physiology, and diseases like cancer.
  • Its dual role in oncogenesis and tumor suppression necessitates further investigation.

Purpose of the Study:

  • To review validated STAT3 downstream target genes.
  • To elucidate the association of these genes with human cancer tumorigenesis and malignant biology.
  • To deepen the understanding of STAT3's complex role in cancer.

Main Methods:

  • Literature review of validated STAT3 downstream target genes.
  • Analysis of studies linking STAT3 targets to cancer development and progression.
  • Focus on genes associated with tumorigenesis and malignant biology.

Main Results:

  • STAT3 regulates numerous genes involved in oncogenesis, tumor growth, and stemness.
  • Evidence suggests STAT3 can act as both an oncogene and a tumor suppressor.
  • The specific effects of STAT3 are context-dependent on cellular environment and tumor type.

Conclusions:

  • A comprehensive understanding of STAT3's upstream regulators, co-regulators, and downstream targets is crucial.
  • This review highlights STAT3 downstream genes validated in relation to human cancer.
  • Further research is needed to fully unravel the multifaceted role of STAT3 in cancer biology.
