Transfection of cells in culture with ASO targeting PTEN reduced PTEN mRNA and protein levels and increased insulin-stimulated Akt phosphorylation in alpha-mouse liver-12 (AML12) cells.

Inhibition of PTEN expression also dramatically reduced insulin concentrations in ob/ob mice, improved the performance of db/db mice during insulin tolerance tests, and increased Akt phosphorylation in liver in response to insulin.

|
In mice, a heterozygous deletion of the Pten gene is associated with increased activation of AKT and with development of pheochromocytomas.

|
Pten insufficiency increased peripheral insulin sensitivity in wild type and Irs2(-/-) mice and increased Akt and Foxo1 phosphorylation in the islets.

Exposure of cultured human umbilical vein endothelial cells to either peroxynitrite (ONOO-) or high glucose significantly inhibited both basal and insulin-stimulated Akt phosphorylation at Ser473 and Akt activity in parallel with increased apoptosis, phosphorylation, and activity of phosphatase and tensin homologue deleted on chromosome 10 (PTEN).

|
Furthermore, protein kinase B/Akt inhibition induced by ONOO- or high glucose and apoptosis triggered by high glucose could be abolished by transfection of PTEN-specific small interfering RNA, suggesting that PTEN mediated the Akt inhibition by ONOO-.

|
Furthermore, administration of PTEN-specific small interfering RNA suppressed diabetes-enhanced apoptosis and Akt inhibition.

We conclude that hyperglycemia triggers apoptosis by inhibiting Akt signaling via ONOO(-)-mediated LKB1-dependent PTEN activation.

In the present study, we investigated the importance of the LKB1-AMPK pathway in regulating tumorigenesis in mice resulting from deficiency of the PTEN (phosphatase and tensin homologue deleted on chromosome 10) tumour suppressor, which drives cell growth through overactivation of the Akt and mTOR (mammalian target of rapamycin) kinases.

|
Here we show that TGF-beta activates Akt in glomerular mesangial cells by inducing the microRNAs (miRNAs) miR-216a and miR-217, both of which target PTEN (phosphatase and tensin homologue), an inhibitor of Akt activation.

|
These studies reveal a mechanism of Akt activation through PTEN downregulation by two miRs, which are regulated by upstream miR-192 and TGF-beta.

|
The mechanism may be, at least partly, attributed to enhancement of PI3K/HSP90/eNOS/Akt cascade, reduction in plasma resistin level, down-regulation of PTEN and slight modification of oxidative state.

In conclusion, NOX2-derived ROS could play a critical role in high glucose-induced ?-cell dysfunction through PTEN-dependent JNK activation and AKT inhibition.

|
Decreased PTEN and increased phospho-Akt were found in kidney of diabetic rats, and in vitro research revealed that high glucose attenuated PTEN expression in a time-dependent manner, concomitant with activation of Akt.

|
Overexpression of miR-21 mimicked the action of high glucose, which included a reduction in PTEN expression and a concomitant increase in Akt phosphorylation.

|
We found that Pten loss in the pancreas causes the elevation of AKT signaling in the liver.

|
The phosphorylation of AKT and its downstream substrate GSK3beta was increased in the liver of PPKO mice, while PTEN level was decreased without detectable excision of Pten allele in the liver of PPKO mice.
