Human-Specific Elimination of Epithelial Siglec-XII Suppresses the Risk of CRC Initiation and Progression [CACO]

ABSTRACT: Human-specific changes in specific Siglecs is one of the reasons put forth as molecular mechanisms that could explain human proneness to developing cancers. The SIGLEC12 gene, which encodes the Siglec-XII protein mainly found on epithelial cells, has a fixed homozygous missense mutation in a critical arginine renders unable to recognize its natural ligand. Additionally, the gene harbors a polymorphic frameshift mutation that eliminates expression of the full-length protein in most humans. We hypothesized that dysfunctional Siglec-XII is involved in cancer progression in humans' epithelia. Here we report that the forced expression of human Siglec-XII in caco-2 cells showed that differentially expressed genes in Siglec-XII cells were enriched for diverse bioenergetic processes.
