However, extending the duration of JF exposure to 30 days did not affect GluA1 or GluA2 surface expression in obesity-prone or obesity-resistant female rats (data not shown; GluA1 Surface: two-way ANOVA no diet × group interaction: F(1,24) = 1.4, p = 0.2; CH vs. JF: F(1,24) = 0.4, p = 0.5; OP vs. OR: F(1,24) = 2.2, p = 0.2; GluA2 Surface: two-way ANOVA no diet × group interaction: F(1,27) = 1.3, p = 0.3; CH vs. JF: F(1,27) = 0.5, p = 0.5; OP vs. OR: F(1,27) = 0.1, p = 0.8). Here, GRIA2 is linked to obesity due to melanocortin 4 receptor deficiency.
