For several human tumour types, allelic loss data suggest that one or more tumour suppressor genes reside telomerlc to the p53 gene at chromosome 17p13.1. In the present study we have used a new strategy, involving molecular analysis of a DNA site hypermethylated in tumour DNA, to identify a candidate gene in this region (17p13.3). Our approach has led to identification of HIC-1 (hypermethylated in cancer), a new zinc-finger transcription factor gene which is ubiquitously expressed in normal tissues, but underexpressed in different tumour cells where it is hypermethylated. Multiple characteristics of this gene, including the presence of a p53 binding site in the 5' flanking region, activation of the gene by expression of a wild-type pS3 gene and suppression of G418 selectability of cultured brain, breast and colon cancer cells following insertion of the gene, make HIC-1 gene a strong candidate for a tumour suppressor gene in region 17pl3.3.
