Core Tip

Core tip: Searching for new colorectal cancer (CRC) molecular markers is a very important objective, because CRC is one of the most common malignancies in the world and one of the most fatal of human neoplasms. Decreased expression of large tumor suppressor 1 in CRC was associated with promoter hypermethylation, but not microsatellite instability status. Such reduced expression may promote progression of CRC.
