Cancer-Critical Genes I: Proto-oncogenes

9.1K
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...

Adaptive Mechanisms in Cancer Cells

5.7K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Area of Science:

  • Genomics
  • Bioinformatics
  • Cancer Research

Background:

  • Vast amounts of single nucleotide polymorphism (SNP) data are generated daily, necessitating advanced characterization techniques.
  • Computational platforms can predict pathogenicity associated with SNPs, aiding in understanding genetic variations.
  • The CENP (Centromere Protein) family plays crucial roles in cell division and is implicated in various diseases.

Purpose of the Study:

  • To improve the prediction quality of SNP characterization methods using machine learning.
  • To identify potential cancer-associated genetic mutations within the CENP protein family.
  • To investigate the role of CENPX, a recently classified protein, in cancer development.

Main Methods:

  • Collected 557 non-synonymous amino acid variants from CENP proteins (excluding CENPE).
  • Employed a machine learning support vector classification method for SNP characterization.
  • Performed multivariate simulations to assess biological impacts of SNPs using available analysis platforms.

Main Results:

  • Identified multiple cancer-associated genetic mutations in CENPI, CENPJ, CENPK, CENPL, and CENPX proteins.
  • Confirmed known tumor mutations for CENPI, CENPJ, CENPK, and CENPL in the COSMIC database.
  • Reported novel cancer-associated mutation evidence for CENPX, previously unlinked to cancer outcomes.

Conclusions:

  • The machine learning model effectively predicted pathogenicity of SNPs in CENP proteins.
  • CENPX represents a new potential target for cancer research due to newly identified associated mutations.
  • Further investigation into CENPX's functional and pathological roles is warranted for cancer research.
