Homozygous deletions of CDKN2A caused by alternative mechanisms in various human cancer cell lines
19 Oct 2004
Abstract excerpt
The CDKN2A tumor-suppressor locus on chromosome band 9p21, which encodes p16(INK4A), a negative regulator of cyclin-dependent kinases, and p14(ARF1), an activator of TP53, is inactivated in many human cancers by point mutation, promoter hypermethylation, and, often, deletion. Homozygous deletions are unusually prevalent at this locus in very different human cancers. In the present study, we compared deletions in...
