HSPA1A and hepatocellular carcinoma: Western blot analysis indicated that Hsp70 inhibitor-induced suppression of BCSCs in TNBC cells was associated with the inhibition of Wnt/β-catenin signaling, as manifested by parallel decreases in the expression levels of β-catenin and its downstream target genes, NFκB and Cyclin D1, in MDA-MB-231, MDA-MB-468, HCC-1937, and HCC-1806 cells (Figure 5A,B).
