Cancer-Critical Genes I: Proto-oncogenes

11.9K
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...

The Ras Gene

7.5K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Small GTPases - Ras and Rho

5.7K
Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Area of Science:

  • Genomics and Molecular Biology
  • Cancer Research

Background:

  • Pseudogenes are DNA sequences similar to functional genes but lack protein-coding ability due to mutations.
  • Historically considered non-functional, recent research reveals pseudogenes possess significant biological roles.
  • These roles include regulating gene expression via microRNA sponging and generating small interfering RNAs.

Purpose of the Study:

  • To review the HMGA1 pseudogene family.
  • To analyze HMGA1 pseudogenes concerning their classification, characterization, and functional implications.
  • To investigate the potential involvement of HMGA1 pseudogenes in cancer progression.

Main Methods:

  • Literature review and analysis of existing studies on HMGA1 pseudogenes.
  • Classification and characterization of HMGA1 pseudogene family members.
  • Exploration of documented and potential functions, including roles in oncogenesis.

Main Results:

  • HMGA1 pseudogenes exhibit diverse characteristics and can be classified into distinct groups.
  • Evidence suggests HMGA1 pseudogenes are not merely evolutionary remnants but possess regulatory functions.
  • Specific HMGA1 pseudogenes are implicated in the development and progression of various cancers.

Conclusions:

  • HMGA1 pseudogenes represent a dynamic and functionally relevant component of the human genome.
  • Understanding HMGA1 pseudogene functions is crucial for comprehending gene regulation and cancer biology.
  • Further research into HMGA1 pseudogenes may reveal novel therapeutic targets for cancer treatment.
