We now demonstrate a defect in proinsulin processing associated with the virtual absence of CPE activity in extracts of fat/fat pancreatic islets and pituitaries.

We conclude that lack of CPE in islet beta-cells results in a marked decrease in processing of proIAPP at its NH(2) (but not COOH) terminus that is associated with attenuated levels of PC2 and (pro)7B2 and a great reduction in formation of mature amidated IAPP.

GAPDH, hnRNP D and hnRNP A/B bind specifically to the p53 CPEs and could potentially be involved in the post-transcriptional regulation of p53.

We show that FoxO1 ablation in pro-opiomelanocortin (Pomc)-expressing neurons in mice (here called Pomc-Foxo1(-/-) mice) increases Carboxypeptidase E (Cpe) expression, resulting in selective increases of alpha-melanocyte-stimulating hormone (alpha-Msh) and carboxy-cleaved beta-endorphin, the products of Cpe-dependent processing of Pomc.

Previously, we demonstrated that lipotoxicity led to the degradation of CPE, but did not affect its related enzyme, carboxypeptidase D (CPD).

|
In this study, we found that CPD was significantly up-regulated by elevated glucose, while CPE was not.

Glucose and insulin did not affect CPD or CPE expression in an ?-cell line.

Furthermore, insulin treatment altered the CPD sub-cellular localization, which was distinct from CPE.

In addition, while our previous study demonstrated that even modest reduction of CPE was sufficient to induce ?-cell apoptosis, CPD knockdown did not affect cell viability.

Specifically, miR-30b* was downregulated by the three treatments, and treatment with GSPE or CPE upregulated miR-1224-3p, miR-197 and miR-532-3p.
