CADM1 and cancer: LncRNA Cell adhesion molecule 1 antisense transcript 1 (CADM1-AS1) gene is located at the chromosome 11, precisely, at the antisense direction of the exon coding for CADM1. CADM1 encodes a membrane protein required for cell-to-cell interactions, regulates cell cycle, apoptosis and differentiation [234] and acts as TSG in several types of cancers [235].
