In the past year, several papers have been published which implicate a link
between alterations in chromatin structure and the development of cancer.
Both histone hyperacetylation and hypoacetylation appear to be important in
the neoplastic process, depending on the target gene involved, In the case
of colon cancer, induction of the p21 gene by histone hyperacetylation may
be a mechanism by which dietary fiber prevents carcinogenesis.
