Background
Wnt-16 is a 40 kDa protein within the Wnt family of secreted, highly conserved, cysteine-rich, palmitoylated cell signaling glycoproteins that play important roles in vertebrate developmental pattern formation, cell fate decision, axon guidance, and tumor formation (1-3). Mature mouse Wnt‑16 shares 92% and 97% aa sequence identity with human and rat Wnt‑16, respectively. Wnt-16 is expressed by uterine stromal cells adjacent to the luminal epithelium during implantation (4). It is
up-regulated during the first embryonic lymphoid progenitor differentiation (5). Congenital heart defects correlate with elevated Wnt-16 in mouse embryos and human amniotic fluid (6). It is secreted by osteoblasts and inhibits monocyte differentiation into osteoclasts, thereby contributing to cortical bone thickness and bone mineral density [1279, 7]. Wnt-16 is over-expressed in cells undergoing replicative senescence, and it is up-regulated in articular cartilage by injury and osteoarthritis (9, 10). Wnt-16b expression in skin is up-regulated and enhances cell survival in human basal cell carcinomas (11). Its expression is also up-regulated by DNA damage (radiation and chemotherapy) in stroma surrounding prostate tumors, causing enhanced survival and treatment resistance in the tumor cells (12). Pre-B acute lymphoblastic leukemia with t(1;19) translocation, creating an E2A-Pbx1 fusion protein, also causes up-regulation of Wnt-16 that confers resistance to apoptosis (13, 14). Wnt-16 signaling through both canonical and JNK-mediated (non-canonical) pathways is reported (9-11).
