GGA*-59 enhances HSF1 hyperphosphorylation and subsequent HSPA1A boosting in HL-1 cardiomyocytes.
Notes: (A) GGA*-59 enhances hyperphosphorylation of HSF1, shown by decreased mobility of HSF1 in the gel. (B) GGA*-59 enhances the ratio of hyperphosphorylated HSF1/HSF1 (quantified higher band/lower band). (C) Representative Western blot showing HSPA1A expression levels for the conditions as indicated. (D) GGA*-59 treatment enhances HSPA1A protein expression levels after 6 hours treatment, compared to nontreated heat shocked control cardiomyocytes. * is P<0.05 compared to Control, # is P<0.05 and #### is P<0.0001 compared to nontreated cardiomyocytes at 1 hour and 6 hours, respectively.
Abbreviations: GGA, geranylgeranylacetone; HSF1, heat shock factor 1; HS, heat shock.
