SRI and type 2 diabetes mellitus: Furthermore, fasting blood glucose levels in patients with pure PC and PCAND before pancreatectomy were positively correlated with sorcin expression levels (Pearson correlation coefficient between sorcin IHC scores and fasting blood glucose level r = 0.281, P = 0.0326) (Fig. 7d), which was not observed in PC + T2DM patients (Pearson correlation coefficient between sorcin IHC scores and fasting blood glucose level, r = -0.0572, P = 0.7722) (Fig. 7e), suggesting a potential link between the upregulation of sorcin and islet dysfunction specific to PCAND.
