YBX1 and neoplasm: Previous studies have reported that YBX1 plays an important role in oncogene expression and tumor progression by directly binding to RNA or DNA.[32, 33] Although our RIP assay failed to show the binding of YBX1 to SREBF2 mRNA (Figure S8C, Supporting Information), ChIP‐qPCR experiments demonstrated that YBX1 was able to bind to the promoter region of SREBF2 gene (Figure 5E; Figure S8D, Supporting Information).
