PRL and type 2 diabetes mellitus: C-peptide levels in HFF control and T2D-PRL-2903 treated animals during hypoglycemia (Figure 4C) were significantly lower at t = 40 min as compared to baseline (HFF: 5.9 ± 0.4 vs. 0.9 ± 0.6 ng/mL, T2D-PRL-2903: 3.8 ± 1.2 vs. 2.2 ± 0.9 ng/mL, p < 0.01 for both comparisons).
