MUC1 as a Putative Prognostic Marker for Prostate Cancer.

ABSTRACT: MUC1 is expressed on the apical surface of glandular epithelium. With functions including protection, adhesion and signaling, MUC1 has been implicated in prostate cancer. There are many splice variants, the best characterized of which are MUC1/1 and MUC1/2 which are determined by a SNP (rs4072037, 3506G>A).Blood DNA from the general population, BPH, sporadic and hereditary prostate cancer subjects were genotyped for the rs4072037 SNP. G allele frequencies were significantly reduced in hereditary prostate cancer (15%) compared to population, BPH or sporadic prostate cancer samples (27%, 39% and 26% respectively). In addition, the G allele was lost from 3 of 8 heterozygous sporadic prostate tumor samples compared to matched blood DNA. Bioinformatics analysis of MUC1 protein sequences provide
