Sex differences in NO and A2A AR-dependent coronary RH in ApoE-HFD mice. A) Summarized effect of L-NAME (NOS inhibitor, 100 μM) and SCH58261 (selective A2A AR antagonist, 1 μM) on baseline coronary flow (A) and % of inhibition (B) of isolated mouse hearts from female and male WT vs. ApoE-HFD mice (N=4 per group). C–F) Summarized effect of L-NAME and SCH58261 on coronary repayment volume (C, the absolute coronary flow, D, % of inhibition), and on repayment/debt ratio (E, the absolute coronary flow; F, % of inhibition) in WT vs. ApoE-HFD mice. *, #, and &p<0.05 vs. control, L-NAME, and SCH58261 treatment in female WT mice, respectively; $p<0.05 vs. L-NAME treatment in female ApoE-HFD mice.
