Further, to study the H<sub>2</sub>S mode of action, the experimental rats were exposed to a PI3K inhibitor (Wortmannin) and GSK3β inhibitor (SB216763) before HIPC protocol, whose results suggest that unlike in normal and DM, HIPC mediates its cardioprotective effect independent of PI3K/GSK3β pathway.
Previous steroid use and lower baseline HbA1c level may be important predictors for developing diabetes in patients with advanced solid tumors treated with PI3K inhibitors, warranting close observation and careful intervention.
Firstly, mouse model of diabetes mellitus (DM) was established and injected with agomir, antagomir or IGF-1 (PI3K/Akt signaling pathway activator) for investigating the role of miR-203 in PIK3CA and the PI3K/Akt signaling pathway.
LiCl, as an inhibitor of GSK-3 apparently reduced the expression of GSK-3β mRNA (<i>P</i> < 0.05) but not the PI3K and Akt comparing with the DM group.
In vivo levels of TUG1 and relative genes in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway in DM rats and control rats were determined by the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR).
In this study, we used Petri nets (PNs) to model and investigate the role of PI3K and OGT pathways, acting as key players in crosstalk between diabetes and breast cancer, resulting in progression of these chronic diseases.
Administering demethylasterriquinone B1, significantly increased the level of PI3K, AKT phosphorylation and GLUT-2 expression, effectively inhibiting the aggravation of diabetes.
We aimed to evaluate the expression of hormone and insulin-related proteins within or related to the PI3K and MAPK pathway in breast tumors of women with or without diabetes mellitus, treated with or without insulin (analogues).
Our study suggests that HD prevents the development of diabetes and improves renal function in the <i>db/db</i> mice and HD regulation of the IRS1-PI3K-GLUT signaling pathway significantly improves diabetic nephropathy.
To address this issue, we investigated the effects of PI3Kγ ablation in <i>db/db</i> diabetic mice, a genetic model of obesity-driven β-cell failure and diabetes.
HMGA1 Mediated High-Glucose-Induced Vascular Smooth Muscle Cell Proliferation in Diabetes Mellitus: Association Between PI3K/Akt Signaling and HMGA1 Expression.
Here, using <i>in vitro</i> and <i>in vivo</i> approaches including osteoblast-specific, conditional FoxO1-knock-out mice, we demonstrate that 1,25(OH)<sub>2</sub>D<sub>3</sub> ameliorates abnormal osteoblast proliferation in DM-induced oxidative stress conditions and rescues the impaired glucose and bone metabolism through FoxO1 nuclear exclusion resulting from the activation of PI3K/Akt signaling.
An important attribute in diabetes and obesity is the presence of high levels of growth factors including insulin in blood which can activate the PI3K/Akt signalling pathway.
Given the availability of a pharmacological inhibitor of this molecular target GE21, we tested the validity of our hypothesis by inducing diabetes in mice with genetic ablation of PI3Kγ or knock-in for a catalytically inactive PI3Kγ.
These studies demonstrate that EPO is an effective neuroprotective agent in the context of diabetes-associated cognitive dysfunction and show that this effect involves the PI3K/Akt/GSK-3β pathway.
In addition, the protein expression levels of phosphatidylinositol 3‑kinase (PI3K)/Akt, glutathione peroxidase and superoxide dismutase activity, glutathione and malondialdehyde content, and inducible nitric oxide synthase (iNOS), caspase‑3 and caspase‑9 activity were detected in the rats with DM.
Moreover, exogenously added TGF-β3 accelerated epithelial wound closure in type 2 rat and type 1 mouse DM corneas via Smad and PI3K-AKT signaling pathways, autoregulation, and/or upregulation of Serpine1, a well-known TGFβ target gene.
Insulin-mediated translocation of GLUT4 involves the PI3K/Akt kinase signal cascade that results in activation of endothelial NO synthase (eNOS). eNOS is dysfunctional during diabetes.
