The browning of white fat has become a hot topic as it could help to lose weight and improve metabolic health. Therefore, this study aims explore the in vivo or thermogenesis effect 6-gingerol (6G), natural bioactive compound ginger, clarify underlying mechanism. results showed that 6G limited gain, improved cold tolerance, increased energy expenditure high-fat diet-induced obese mice. Moreover...

Mutation or amplification in the PIK3CA gene is one of most frequent somatic mutations hormone-dependent Her2neu-negative breast cancer (HR+ Her2neu- cancer) and associated with an increased risk relapse, progression death. Understanding mechanisms leading to hyperactivation PI3K-mediated signaling cascade has led a new class drugs aimed at inhibiting/suppressing it. Studies efficacy pan-PI3K i...

Objective: Stanozolol is an anabolic androgenic steroid (AAS) that widely used by teenagers and athletes in bodybuilding, sports, athletics. The potential effects of stanozolol kidney functions have not been defined. In this study we investigated the expression tumor suppressor protein phosphatase tensin homolog (Pten) mRNA levels phosphatidylinositol 4,5-bisphosphate 3 kinase (Pi3k) B (Akt1) s...

Yang He Decoction (YHD), a classical Chinese medicine prescription, is used to treat bone and joint diseases. However, there are few mechanism studies for YHD on the use of tuberculosis (BT) corresponding action YHD. In present study, chemical ingredients targets were revealed by network pharmacology method, an ingredient–target–disease was visualized analyzed. Then, gene ontology enrichment an...

Background—We have recently shown that genetic inactivation of phosphoinositide 3-kinase (PI3K ), the isoform linked to G-protein–coupled receptors, results in increased cardiac contractility with no effect on basal cell size. Signaling via the G-protein–coupled -adrenergic receptors has been implicated in cardiac hypertrophy and heart failure, suggesting that PI3K might play a role in the path...

As accumulating evidences suggest close involvement of phosphatidylinositol 3-kinase (PI3K) in various diseases particularly cancer, considerable competition occurs in development of PI3K inhibitors. Consequently, novel PI3K inhibitors such as ZSTK474, GDC-0941 and NVP-BEZ235 have been developed. Even though all these inhibitors were reported to inhibit class I PI3K but not dozens of protein ki...

The phosphoinositide 3-kinase (PI3K/Akt) pathway is activated in acute myelogenous leukemia (AML) and is promising for targeted inhibition. Ninety-two patients with primary AML were analyzed for PI3K/Akt constitutive activation. Fifty percent of the patients presented with constitutive PI3K activation (PI3K (+)). No difference was observed between PI3K (+) and PI3K (-) groups concerning age, se...

Recent studies have shown that hyperinsulinemia may increase the cancer risk. Moreover, many tumors demonstrate an increased activation of IR signaling pathways. Phosphatidylinositol 3-kinase (PI3K) is necessary for insulin action. In epithelial cells, which do not express GLUT4 and gluconeogenic enzymes, insulin-mediated PI3K activation regulates cell survival, growth, and motility. Although t...

BACKGROUND The phosphoinositide 3-kinase (PI3K)/Akt pathway is involved in neuroblastoma development where Akt/PKB activation is associated with poor prognosis. PI3K activity subsequently activates Akt/PKB, and as mutations of PI3K are rare in neuroblastoma and high levels of PI3K subunit p110delta is associated with favorable disease with low p-Akt/PKB, the levels of other PI3K subunits could ...

Class IA phosphoinositide 3-kinases (PI3Ks) are signaling enzymes with key roles in the regulation of essential cellular functions and disease, including cancer. Accordingly, their activity is tightly controlled in cells to maintain homeostasis. The formation of multiprotein complexes is a ubiquitous mechanism to regulate enzyme activity but the contribution of protein-protein interactions to t...
