    MedChemExpress camp pka pathway inhibitor h89
    Inhibition of the cAMP/PKA pathway attenuates GPER1-induced ferroptosis in esophageal cancer cells. KYSE70 and KYSE150 cells were treated with or without the cAMP/PKA inhibitor <t>H89</t> (10 μM) for 24 h under four conditions: negative control with vehicle (NC + Veh), negative control with H89 (NC + H89), GPER1 overexpression with vehicle (GPER1-OE + Veh), and GPER1 overexpression with H89 (GPER1-OE + H89). a,d ) Cell viability was determined by CCK-8 assay in KYSE70 ( a ) and KYSE150 ( d ) cells. b,e ) Intracellular ROS levels were measured by flow cytometry using a DCFH-DA probe in KYSE70 ( b ) and KYSE150 ( e ) cells. c,f ) Intracellular Fe²⁺ content was quantified by an iron assay kit in KYSE70 ( c ) and KYSE150 ( f ) cells. g ) Protein expression levels of the ferroptosis markers ACSL4 and GPX4, and the cAMP pathway components p-CREB1 and CREB1, were analyzed by Western blotting in both KYSE70 and KYSE150 cells; left panels show representative Western blot images, and the right panels show the corresponding quantitative densitometric analysis of the protein bands, normalized to GAPDH (for ACSL4 and GPX4) or total CREB1 (for p-CREB1). All quantitative data are presented as the mean ±SD from three independent experiments (n=3). Statistical significance was determined by one-way ANOVA followed by Tukey's post-hoc test; * p <0.05, ** p <0.01, *** p <0.001, **** p <0.0001; ns, not significant.
