The misregulation of the equilibrium between acetylation and deacetylation has also been associated with the manifestation of certain cancers. If histone acetyltransferases are inhibited, then damaged DNA may not be repaired, eventually leading to cell death. Controlling the chromatin remodeling process within cancer cells may provide a novel drug target for cancer research. Attacking these enzymes within cancer cells could lead to increased apoptosis due to high accumulation of DNA damage. One such inhibitor of histone acetyltransferases is called garcinol. This compound is found within the rinds of the garcinia indica fruit, otherwise known as mangosteen. To explore the effects of garcinol on histone acetyltransferases, researchers used HeLa cells. The cells underwent irradiation, creating double-strand breaks within the DNA, and garcinol was introduced into the cells to see if it influenced the DNA damage response. If garcinol is successful at inhibiting the process of non-homologous end joining, a DNA repair mechanism that shows preference in fixing double-strand breaks, then it may serve as a radiosensitizer, a molecule that increases the sensitivity of cells to radiation damage. Increases in radiosensitivity may increase the effectiveness of radiotherapy.
