Adaptive Mechanisms in Cancer Cells

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,...

Transduction

Transduction

Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome...

Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

M-Cdk Drives Transition Into Mitosis

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
M cyclin...

Area of Science:

Oncology
Biophysics
Cell Biology

Background:

Physical forces play a significant role in tumor progression, but their precise impact on cancer phenotypes remains largely unknown.
Understanding how mechanical forces influence cancer cell behavior is crucial for developing effective therapeutic strategies.

Purpose of the Study:

To investigate the impact of volumetric compression on melanoma cells using an integrative approach.
To identify compression-induced transcriptomic changes and associated phenotypic responses in melanoma.

Main Methods:

Bioinformatic analysis to screen for significant compression-induced transcriptomic alterations.
Phenotypic assessment of melanoma cells under volumetric compression.

Main Results:

Compression-induced transcriptomic changes correlate with varied patient prognoses.
Volumetric compression inhibits melanoma cell proliferation and migration.
Compression induces organelle and oxidative stress, increases pigmentation, and enhances resistance to cisplatin treatment.

Conclusions:

Volumetric compression acts as a double-edged sword in melanoma progression.
Mechanical forces significantly drive tumor evolution and phenotypic diversity in melanoma.
