Scientists discover an “impossible” cellular survival pathway that could help fight cancer
Source: ScienceDaily
What the research found
Scientists discovered a surprising backup system that lets mammalian cells make the essential amino acid cysteine even when the pathways once considered indispensable are disabled. The same survival mechanism may help cancer cells resist treatment, raising the possibility that shutting it down could make tumors easier to kill.
