Linc02042 interacts with YBX1. a RPISeq database predicting the interaction probability between linc02042 and YBX1. Both RF and SVM classifier greater than 0.5 mean positive. b RNA pull-down coupled Western blotting analysis in ESCC cells. c RIP assays in ESCC cells with IgG and YBX1 antibodies, followed by qRT-PCR analysis of linc02042 expression. d Western blotting analysis of YBX1 protein expression in linc02042-depleted ESCC cells. e RIP assays in ESCC cells with IgG and YBX1 antibodies in linc02042-depleted ESCC cells. f qRT-PCR analysis of c-Myc expression in linc02042-overexpressed cells treated with YBX1 siRNA. g The assessment of cell viability and invasion respectively detected by CCK-8 and Transwell assays in linc02042-overexpressing cells transfected with YBX1 siRNA. **p < 0.01, ***p < 0.001
