The serine/threonine protein kinase Akt is a key molecule in the phosphatidyl inositol 3-kinase pathway that is often overactivated in human cancers. Three Akt isoforms (Akt1, Akt2, Akt3) have been identified in human cells and they show different distribution and have non-redundant functions. The aim of this study was to determine whether the expression, phosphorylation, and localization of Ak...
Akt1 is a multi-functional protein, implicated in multiple human solid tumors. Pertaining to its key role in cell survival, Akt1 is under focus for development of targeted therapies. Functional diversity of Akt1 is a result of its interactions with other proteins; which changes with changing context. This investigation was designed to capture the dynamics of Akt1 Interactome as a function of it...
Vascular remodeling is essential for tissue repair and is regulated by multiple factors, including thrombospondin-2 (TSP2) and hypoxia/VEGF-induced activation of Akt. In contrast to TSP2 knock-out (KO) mice, Akt1 KO mice have elevated TSP2 expression and delayed tissue repair. To investigate the contribution of increased TSP2 to Akt1 KO mice phenotypes, we generated Akt1/TSP2 double KO (DKO) mi...
3-Phosphoinositide-dependent protein kinase-1 (PDK1) and Akt1 are two closely related components of the phosphatidylinositol-3 kinase (PI3K) pathway, which is aberrantly regulated in breast cancer. Despite the importance of PDK1, few studies have evaluated it as a potential target for cancer therapy compared with studies of Akt1. We hypothesized that PDK1 is a superior target in the PI3K pathwa...
OBJECTIVE Deletion of Akt1 leads to severe atherosclerosis and occlusive coronary artery disease. Vascular smooth muscle cells (VSMCs) are an important component of atherosclerotic plaques, responsible for promoting plaque stability in advanced lesions. Fibrous caps of unstable plaques contain less collagen and ECM components and fewer VSMCs than caps from stable lesions. Here, we investigated ...
BACKGROUND Postnatal growth of the heart chiefly involves nonproliferative cardiomyocyte enlargement. Cardiac hypertrophy exists in a "physiological" form that is an adaptive response to long-term exercise training and as a "pathological" form that often is a maladaptive response to provocative stimuli such as hypertension and aortic valvular stenosis. A signaling cascade that includes the prot...
RATIONALE Coronary artery disease, the direct result of atherosclerosis, is the most common cause of death in Western societies. Vascular smooth muscle cell (VSMC) apoptosis occurs during the progression of atherosclerosis and in advanced lesions and promotes plaque necrosis, a common feature of high-risk/vulnerable atherosclerotic plaques. Akt1, a serine/threonine protein kinase, regulates sev...
Objective: The purpose of this study was to investigate the effect of 12 weeks aerobic training on the expression of AKT1 and mTORc1 genes in the left ventricle of T2DM rats. Materials and Methods: The statistical sample consisted of 21 male wistar rats from the Pasteur Institute in Tehran. (10 weeks old weighing 220 ± 20 grams). They were divided into three groups: diabetic aerobic training, ...
The purpose of the present study was to determine the effect of Akt gene ablation on Akt/Forkhead Box O (FOXO) signaling and atrogene expression. This was accomplished by studying wild-type (WT) and isoform-specific Akt knockout (Akt1(-/-) and Akt2(-/-)) mice. The ability of insulin to promote Akt phosphorylation on Ser(473) was significantly lower in extensor digitorum longus (EDL) and soleus ...
E-mail: [email protected] Tel (Fax): 86-22-2352 2919 OBJECTIVE To confirm the role played by AKT1 and AKT2 in the bcatenin/Tcf-4 signaling pathway in promoting malignant transformation of glioma cells. METHODS LN229 cells were divided into five groups: a control group, acetone (ACE)group, acetylsalicylic acid (ASA; aspirin) group, ASA+AKT1 plasmid group and ASA+AKT2 plasmid group. Western b...
