Genomic instability (gin) is a hallmark of cancer cells that facilitates the acquisition of mutations conferring aggressive or drug-resistant phenotypes during cancer evolution chromosomal instability (cin) is a form of gin that involves frequent cytogenetic changes leading to changes in chromosome copy number (aneuploidy). They’ve been studying a phenomenon called ‘chromosomal instability’ in bowel cancer cells, where cells’ dna becomes more and more disordered as they grow and divide, causing ever-greater genetic chaos.

Abstract chromosomal translocations are a hallmark of cancer unraveling the molecular mechanism of these rare genetic events requires a clear distinction between correlative and causative risk-determinants, where technical and analytical issues can be excluded.

[perspective] chromosomal chaos silences immune surveillance not all cancers, and not all individuals with the same cancer type, respond equally to immunotherapy—the use of antibodies to block so-called immune checkpoints in t cells—thereby unleashing immune responses against tumor cells. Studies have attempted to look into this chromosomal chaos before, but have had to do so retrospectively using only one tumour region this means they’ve looked back at patient samples and taken a snapshot of what’s going on at a certain point in time – providing only a static measure of cancer’s chromosomal complexity. “ cancer was not disorganized chromosomal chaos it was organized chromosomal chaos ” -- siddhartha mukergee, the emperor of all maladies perhaps the most inexplicable -- and also the most terrifying -- aspect of cancer is that the disease stems from your own body turning against you.
