In this study, we demonstrate in isolated rat pancreatic islets that the biosynthesis of PC3 was specifically stimulated by glucose relatively parallel to that of proinsulin.

We suggest that co-ordinate stimulation of PC3 biosynthesis, along with that of its proinsulin substrate, elucidates an additional control point by which the mechanism of proprotein processing might be regulated.

Proinsulin is converted to insulin by the concerted action of two sequence-specific subtilisin-like proteases termed prohormone convertase 2 (PC2) and prohormone convertase 3.

Proinsulin is converted to insulin by the concerted action of two sequence-specific subtilisin-like proteases termed prohormone convertase 2 (PC2) and prohormone convertase 3 (PC3).

Expressions of insulin and PC3, but not PC2, are coordinately regulated by glucose, consistent with the important role of PC3 in regulating proinsulin processing.

Our scant knowledge in this area is confined mostly to a descriptive account of the fate of the major secreted components, principally insulin and the enzymes PC1, PC2, and CPH involved in the proteolytic conversion of proinsulin to insulin.

Using this cell line, we found that suppression of Pdcd4 resulted in an increased release of CgA (chromogranin A) and Sg II (secretogranin II), and was accompanied by an up-regulation of intracellular PC1 (proprotein convertase 1/3).

Our results are of particular interest, as we observed that pioglitazone, an oral medication used in the treatment of Type 2 diabetes, decreased Pdcd4 levels, activated Akt, increased CgA and Sg II secretion and augmented PC1 protein in Bon-1 cells.

Transduced expression of PDX-1, NEUROD or PDX-1/VP16 led to expression of not only INS but also GLUT2 and prohormone convertase 1 and 2.

Incubation of these cells with an agonist of TGR5 increased PC1 promoter activity and GLP-1 secretion suggesting that this is a mechanism for switching processing to GLP-1 in the pancreas.

Two loci (LARP6 and SGSM2) have not been previously related to metabolic traits, one (MADD) has been associated with fasting glucose, one (PCSK1) has been implicated in obesity, and four (TCF7L2, SLC30A8, VPS13C/C2CD4A/B, and ARAP1, formerly CENTD2) increase T2D risk.

To investigate whether the single nucleotide polymorphisms (SNPs) of TCF7L2, SLC30A8, PCSK1 and PCSK2 were associated with T2DM as well as with proinsulin conversion in a Han Chinese population from Chongqing.
