(A and C) Kcnj11 expression measured by qPCR in pancreatic islets treated with vehicle Con or CDK2i (n = 3 mice) (A) or islets isolated from Con and CDK2-iKO mice (n = 3 mice per genotype) (C).
(B and D) Measurements of KATP conductance in islets treated with vehicle Con or CDK2i (B) or CDK2-iKO islets (C). Left: representative current-voltage relationship collected during a voltage ramp, showing conductance (slope) changes in β cells measured in 10 mM glucose (10G) and after treatment with 200 μM diazoxide (DZ). Right: KATP conductance was reduced in CDK2i-treated (n = 7) relative to vehicle-treated Con (n = 11) β cells (B) and in CDK2-iKO β cells relative to Cons treated with Ad-Cre (n = 11 cells from 3 mice each genotype) (D).
Data are shown as mean ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001 by t test (A and C) or one-way ANOVA (B and D).
