Low expression of the WAF1/CIP1 gene product, p21, in enzyme-altered foci induced in rat liver by diethylnitrosamine or phenobarbital.

abstract：:Cancer cells often exhibit altered epigenetic signatures that can misregulate genes involved in processes such as transcription, proliferation, apoptosis and DNA repair. As regulation of chromatin structure is crucial for DNA repair processes, and both DNA repair and epigenetic controls are deregulated in many cancers...

Human melanoma, in advanced stage, is hardly curable, due to development of several strategies that impair apoptosis induced by the death receptor and the mitochondrial pathways of apoptosis. Among these apoptosis escape stra...

Co-amplification of the DDX1 gene is a consequence of the short physical distance between the two genes.
