Weakness exposed in most common cancer gene

Weakness exposed in most common cancer gene

Researchers at the NYU medical center have discovered a weakness in the most commonly mutated gene in human cancer. The weakness is known as mutant K-Ras, and it is said that this weakness can be exploited with drug chemotherapy to prevent the tumor from growing. It was suspected that mutant K-Ras was the main cause behind about a third of all cancers. The lab preformed experiments and in the experiments  it showed that in cancer cells that K-Ras tumor growth was reliant on the cells' need to check and mend to their DNA. Researches discovered that a commonly used chemotherapy drug maybe more effective in killing K-Ras cancer cells by blocking their ability to check their DNA for any damage.
