Abstract: Abstract: Protein kinase C (PKC) is a family of protein kinase enzymes that can phosphorylate
other proteins and influence their functions, such as signal transduction, cell survival, and death. Increased
diacylglycerol (DAG) concentrations, which are typically observed raised in hyperglycemic
situations such as diabetes mellitus, can also activate PKC enzymes (DM). On the other
hand, PKC isomers have been shown to play an essential role in diabetes and many hyperglycemic
complications, most importantly atherosclerosis and diabetic cardiomyopathy (DCM). As a result,
blocking PKC activation via DAG can prevent hyperglycemia and related consequences, such as
DCM. Wogonin is a herbal medicine which has anti-inflammatory properties, and investigations
show that it scavenge oxidative radicals, attenuate nuclear factor-kappa B (NF-κB) activity, inhibit
several essential cell cycle regulatory genes, block nitric oxide (NO) and suppress cyclooxygenase-
2 (COX-2). Furthermore, several investigations show that wogonin also attenuates diacylglycerol
DAG levels in diabetic mice. Since the DAG-PKC pathway is linked with hyperglycemia
and its complications, Wogonin-mediated DAG-PKC attenuation can help treat hyperglycemia and
its complications.
