After 36 h of transfection, cells were incubated for further 8 h without (Without insulin) or with (With insulin) insulin (1 nM) in the absence (Control) or presence of A1AR or A2AAR antagonists. Cells were also transfected with the empty pGL3-basic vector or pGL3-control vector (SV40 pGL3) as negative or positive controls, respectively (see “Materials and methods”). In a and c, *P < 0.05 vs. corresponding values in Normal. †P < 0.05 vs. values in the absence of insulin or A1AR antagonist. ‡P < 0.05 vs. all other corresponding values.
