Adaptive Mechanisms in Cancer Cells

6.8K
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:

  • Oncology
  • Biophysics
  • Cell Biology

Background:

  • Cancer cell mechanical deformability correlates with malignancy potential.
  • Current mechanical testing methods for clinical cancer diagnosis are limited.
  • Phagocytic capacity is explored as a potential surrogate marker for mechanical properties and malignancy.

Purpose of the Study:

  • To establish a Triangular Correlation (TrC) between cancer cell deformability, phagocytic capacity, and aggressiveness.
  • To validate phagocytic measurements as a surrogate for mechanical testing in cancer diagnostics.
  • To investigate the potential of phagocytosis as a biomarker for cancer aggressiveness and precision medicine.

Main Methods:

  • Investigated the Triangular Correlation (TrC) in human prostate, bladder, and melanoma cancer cells.
  • Sorted cancer cell subpopulations based on phagocytic capacity.
  • Analyzed gene expression, epigenetic signatures, and cell deformability in different subpopulations.
  • Utilized a computational model to predict cancer phenotypes.

Main Results:

  • Higher phagocytic capacity correlated with increased cancer cell aggressiveness both ex vivo and in vivo.
  • Enhanced phagocytosis and aggressiveness were linked to greater cell deformability.
  • Differences in gene expression and epigenetic profiles were observed between subpopulations.
  • A computational model successfully predicted enhanced phagocytic and aggressiveness phenotypes.

Conclusions:

  • Phagocytic measurements can serve as a mechanical surrogate marker for cancer malignancy.
  • This study provides proof of concept for using phagocytosis in cancer diagnostics.
  • The findings support the application of phagocytic capacity for precision medicine in oncology.
