Abstract

5-Fluorouracil (5-FU) resistance is an urgent problem of colorectal cancer (CRC) chemotherapy that needs to be resolved. To investigate 5-FU-associated lncRNAs for CRC might be of great significant. LncRNA ENSG00000254615 was detected by RNA-sequencing. ENSG00000254615 were detected highly expressed in 5-FU-sensitive CRC cells and tissue specimens, and inhibited cell proliferation and attenuated 5-FU resistance in vitro and in vivo. Furthermore, ENSG00000254615 participated in the regulation of p21 and Cyclin D1. Taken together, we proposed that ENSG00000254615 inhibits proliferation and attenuates 5-FU resistance of CRC by regulating p21 and Cyclin D1 expression.

Keywords: 5-FU resistance; Colorectal cancer; lncRNA; proliferation.
