Histone hyperacetylation affects G2/M cell cycle transition

Funded Activity Summary

The mechanisms controlling cell growth are often disrupted in cancers. We have identified on such growth control mechanism. When normal body cells are treated with a particular family of drugs known as histone deacetylase inhibitors, they react by stopping proliferating, but will resume normal growth when the drug is removed. However, we have found that similarly treated tumour cells are killed by these drugs. The difference between the normal and tumour cells is the functionality of a particular growth control. The identification of how this growth control mechanism operates in normal cells, and defining the defect in tumour cells has the potential to identify new targets for more specific and potent anti-cancer drugs. The increased specificity, i.e. destruction of only the tumour cells while have little or no effect on the surround normal body tissue, would be extremely beneficial as one of the drawbacks to conventional anti-cancer treatments is their unwanted normal tissue toxicities. This is cause of the many debilitating side effects associated with chemo and radiotherapy which can limit the clinical effectiveness of these treatments.
