intracellular import of LDL-C by LDL-R activation may facilitate oxidation processes, ultimately leading to altered structural integrity of the β cells. Oxidation products may also lead to overproduction of nitric oxide (NO) by cytokines, again potentially inducing β cell apoptosis and impairing insulin secretion. In addition, inhibition of isoprenoids by reduced HMGCR activity may cause down-regulation of glucose transporter type 4 (GLUT4) expression on adipocytes, leading to impaired glucose uptake [38].
