Expression analysis performed using real-time RT-PCR showed that HSPB8 mRNA is highly expressed in iPSCs, in BC cells (MCF-7) and in hepatocellular carcinoma (HepG2), while its expression is much lower in prostate cancer (PC) cells (PC3 and DU145 cells) and in melanoma cells (BML) (Figure 1, panel A). Here, HSPB8 is linked to hepatocellular carcinoma.
