Ectopic expression of SND1 has been observed in various tumors including colon cancer, breast cancer, prostate cancer and hepatocellular carcinoma (HCC), indicating a positive role of SND1 in tumor initiation and progression.
Staphylococcal nuclease homology domain containing 1 (SND1), a component of RISC, is frequently up-regulated in human colon cancers and also chemically induced colon cancers in animals.
Up-regulation of SND1 may thus occur at a very early stage in colon carcinogenesis and contribute to the posttranscriptional regulation of key players in colon cancer development, including APC and beta-catenin.
