RARB and neoplasm: Among the genes that are candidates as markers of cervical cancer risk there are genes involved in cell-cycle control and tissue differentiation regulation (Retinoic Acid Receptor Beta, RARB); that are positive mediator of programmed cell death (apoptosis) (Death Associated Protein Kinase 1, DAPK1); that encode a member of the immunoglobulin superfamily and is one of the crucial tumor suppressors involved in cell adhesion (Cell Adhesion Molecule 1, CADM1); and a transcriptional activator involved in developmental processes (Paired Box 1, PAX1).
