Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

Cancer cells that accumulate extra copies of their entire chromosome set can start behaving like immune cells, swallowing ...

A study shows that extra chromosomes in fetal cells create pre-leukemic clones that can persist for years, requiring later triggers to develop into leukemia, revealing a two-stage disease model.
