MCF10A cells exhibited significantly increased expression of HSP90AA1, CARHSP1, HSPA12A and decreased expression of HSPB1, HSPBL2, HSPA6, and HSPA7 (C vs H), while the three breast cancer lines showed no significant 2-fold or greater alterations in the expression of these genes (C’ vs H’). Here, HSPB1P1 is linked to breast cancer.
