Phosphorylation of serine at position 845 of the GluA1 subunit is significantly decreased in good ATSET rats. (A) The phosphorylation state of the serine residue at position 831 was not altered, but (C) at position 845, the good ATSET group showed lower phosphorylation of serine compared to the other two groups. (B) Interestingly, significantly lower expression of GluA1 subunit of the AMPA receptors was noted in the good ATSET neutron rats compared to the other two groups. Crude synaptosomal fractions from three-four animals per group were used in the assessment and statistical significance (* p < 0.05, ** p < 0.01) was determined using non-parametric, Kruskal–Wallis t-test.
