|
The presence and regulation of a hormone-sensitive cyclic GMP-inhibited cyclic nucleotide phosphodiesterase (cGI PDE) in rat brown adipose cells was investigated. cDNA clones for two cGI PDE isoforms, cGIP1 and cGIP2, have been isolated.

|
When cells were incubated with insulin before membrane preparation, cGI PDE activity in the microsomal fraction was increased by 2- to 2.5-fold within 10 min.

In cells incubated with both insulin and isoproterenol, microsomal cGI PDE activity was similar to that in microsomal fractions isolated from cells incubated with insulin alone.

The bpV(pic) inhibited the lipolytic effect of isoprenaline to the same extent as insulin; however, when the cGMP-inhibitable low-K(m) phosphodiesterase (cGI-PDE) was blocked with the specific inhibitor OPC 3911, the antilipolytic effect of insulin, but not that of bpV(pic), was completely prevented.
|
14 |
8635677
|
These findings indicate that bpV(pic) exerts its antilipolytic effect not only through cGI-PDE activation, similar to the effect of insulin, but also by means of other mechanisms.
|

|
In contrast, in situ tyrosine phosphorylation of the insulin receptor beta-subunit as well as that of several other proteins was clearly increased in cells which were treated with bpV(pic), whereas vanadate only amplified insulin-stimulated tyrosine phosphorylation.

With a view of understanding the potential roles of phosphodiesterase (PDE)3 in the acceleration of atherosclerosis in diabetes, we have analyzed the in vivo levels of low Km cAMP PDE3 and PDE4 activities as well as PDE3A and PDE3B mRNA in a relevant animal model.

Thus, in the aorta of atherosclerosis-prone insulin-resistant cp/cp rats, PDE3A gene expression is upregulated, resulting in significantly higher PDE3 activity.

Furthermore, determination of PDE3 activity and PDE3A and PDE3B mRNA levels in heart and white and brown fat tissues of JCR:LA-cp rats revealed that PDE3B mRNA and activity in white adipose tissue is downregulated in this diabetic animal model, and that PDE3A and PDE3B genes are tissue-specifically expressed and differentially regulated in aorta and adipose tissue, respectively, under hyperinsulinemic conditions.

Specific depletion of PDE3A with small interfering (si) RNA (siPDE3A) led to a small (67%) increase in the insulin response to glucose in INS-1E cells but not rat islets. siPDE3A had no effect on the glucagon-like peptide-1 (10 nmol/liter) potentiated insulin response in rat islets.

Depletion in PDE8B levels in rat islets using similar technology (siPDE8B) increased insulin response to glucose by 70%, the potentiation being of similar magnitude during the first and second phase insulin release.

We propose that PDE8B, an 3-isobutyl-1-methylxanthine-insensitive cAMP-specific phosphodiesterase, could prove a novel target for enhanced insulin response, affecting a specific pool of cAMP involved in the control of insulin granule trafficking and exocytosis.
