Adaptive Mechanisms in Cancer Cells

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,...

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,...

Area of Science:

  • Bio-inspired computing
  • Computational biology
  • Machine learning in oncology

Background:

  • Ovarian cancer is a leading cause of cancer death, with survival rates dramatically increasing when detected early.
  • Current diagnostic methods struggle to identify the transition from benign to malignant tumors, leading to late-stage diagnoses in most cases.
  • Early and precise detection of ovarian cancer is crucial for improving patient outcomes and cure rates.

Purpose of the Study:

  • To develop and validate a novel computational model for accurate ovarian carcinoma classification.
  • To investigate the potential of a hybrid algorithm combining discretization of food sources for artificial bee colony (DfABC) and support vector machine (SVM) for oncogene detection.
  • To identify novel oncogenes associated with ovarian cancer progression.

Main Methods:

  • A hybrid DfABC-SVM model was developed for ovarian carcinoma and oncogene classification.
  • The human ovarian cDNA expression database, comprising 41 patient samples and 9600 genes, was utilized.
  • Feature selection methods were employed to identify 15 key oncogenes for analysis.

Main Results:

  • The DfABC-SVM model achieved an average accuracy of 94.76% across eight classification experiments.
  • The model successfully classified 15 selected oncogenes into eight distinct categories based on gene expression in various pathological stages.
  • Several previously undiscovered oncogenes with significant links to ovarian and other cancers were identified.

Conclusions:

  • The developed DfABC-SVM model demonstrates high accuracy and potential for early ovarian cancer detection and diagnosis.
  • The study successfully identified novel oncogenes, contributing to a deeper understanding of ovarian cancer pathogenesis.
  • This research highlights the efficacy of bio-inspired computing and machine learning in advancing oncological diagnostics.
