KHDRBS3 promotes multi-drug resistance and anchorage-independent growth in colorectal cancer.

ABSTRACT: 5-Fluorouracil (5-FU) is one of the most frequently used pharmacological agents in the treatment of colorectal cancer (CRC). Resistance to chemotherapy is a major cause of treatment failure of CRC, and it is a well known fact that cancer stem cells play a significant role in the acquisition of drug resistance. In this study, we focused on the KHDRBS3 gene that encodes KH RNA Binding Domain Containing, Signal Transduction Associated 3. We first clarified the relationship between KHDRBS3 and 5-FU resistance. We then observed higher expression levels of KHDRBS3 in KRAS-mutant organoids and cell lines in comparison with KRAS wild-type organoids and cell lines. Immunohistochemical analysis using CRC cases revealed that the prognosis of KHDRBS3-positive patients was significantly worse compared
