ANXA2 and hepatocellular carcinoma: Moreover, RNA immunoprecipitation (RIP) assays showed that LINC01133 was enriched in lysates of MHCC97H cells treated with anti‐ANXA2 antibody in comparison with lysates of MHCC97H cells treated with IgG protein (Figure 6E), further confirming the interaction between LINC01133 and ANXA2 in HCC cells.
