Since heme oxygenase (HO) expression regulates the level of ROS by increasing antioxidant, such as glutathione and bilirubin, we investigated whether upregulation of HO-1 modulates the levels of iNOS and eNOS and altered vascular responses to phenylephrine (PE) and acetylcholine (Ach) in aorta and femoral arteries of diabetic (streptozotocin (STZ)-induced) rats.

|
Upregulation of HO-1 expression by cobalt protoporphyrin (CoPP), an inducer of HO-1 protein and activity, conferred an increase in eNOS and differentially decreased iNOS protein levels (p<0.05).

|
Therefore, overexpression of HO-1 may mediate an increase in eNOS and a decrease in iNOS, potentially contributing to restoration of vascular responses in diabetic rats.

These novel findings provide a link between the increase in HO-1 activity, with its concurrent enhanced production of carbon monoxide (CO) and bilirubin, a decrease in infiltrated CD11c(+) dendritic cells and an increase in anti-apoptotic proteins, including RSK and BcL-xL, in the interdiction of the diabetic state.

ZF rats displayed a decrease in both HO activity and HO-1 and HO-2 protein levels and an increase in tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 compared with Zucker lean (ZL) rats.

17 |
18334666

Up-regulation of HO-1 caused adipose remodeling, smaller adipocytes, and increased adiponectin secretion in the culture medium of human bone marrow-derived adipocytes.
|

|
In summary, this study demonstrates that the antiobesity effect of HO-1 induction results in an increase in adiponectin secretion, in vivo and in vitro, a decrease in TNF-alpha and IL-6, and a reduction in weight gain.

|
Thus induction of HO-1 accompanied with increased plasma adiponectin levels in diabetic hypertensive rats alters the phenotype through a reduction in oxidative stress, thereby permitting endothelial cells to maintain an anti-apoptotic environment and the restoration of endothelial responses thus preventing hypertension.
