Epigenetic changes such as DNA methylation, histone modifications etc., are also important in cancer formation. InsP6 reverses the carcinogen-induced epigenetic changes in at least two different carcinogen-induced lung cancer models. InsP6 has also been found to repress telomerase activity in prostate and brain cancers. For cancer to metastasize, the cells need access to blood vessels to disseminate. Formation of new blood vessels - angiogenesis facilitates the process. InsP6 has been demonstrated to inhibit angiogenesis both in vitro and in vivo. This is mediated by suppression of proangiogenic factors such as vascular endothelial growth factor (VEGF).
