The present study aims to identify the key genes involved in acquired oxaliplatin-resistant in CRC by confirming the oxaliplatin resistance index (OX-RI)….To this aim, differentially expressed genes (DEGs) between the sensitive- and oxaliplatin-resistant CRC cells related to the two identified data series were obtained....Based on the results, TGM2, HMGA2, FXYD3, and LGALS4 genes are related to oxaliplatin-resistant CRC and may serve as novel therapeutic targets.
