Both the formation of long-term memory (LTM) and dendritic spine growth that serves as a physical basis for the long-term storage of information require de novo protein synthesis. Memory formation also critically depends on transcription. Adenosine monophosphate-activated protein kinase (AMPK) is a transcriptional regulator that has emerged as a major energy sensor that maintains cellular energ...

This study aimed to explore the influence of soybean meal on intestinal mucosa metabolome and signaling pathway mirror carp ( Cyprinus carpio Songpu) by integrating liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based metabolomics. Fish (Con) was control group, (Dou) AMPK activator (300 mg kg –1 Metformin, Met) inhibitor (0.2 Compound-c, c-Com) which added were experimental groups. T...

Background: Liver cancer is associated with a high mortality rate worldwide. Hepatocellular carcinoma (HCC) constitutes large proportion of primary liver cancers, and most its alterations currently remain untreatable. Diallyl trisulfide (DATS), the main chemical constituent allicin, affects tumour development by regulating cell apoptosis. Allicin-induced autophagy could contribute to apoptosis ...

ATP depletion is one of the pathological bases in cerebral ischemia. Electro-acupuncture (EA) widely used clinical practice for However, mechanism EA remains unclear. The purpose this study was to investigate whether could activate AMPK/PGC-1α/TFAM signaling pathway and, consequently, increase preservation rats with In study, 48 were randomly divided into four groups as a sham-operation control...

Augmented AMP-activated protein kinase (AMPK) activity inhibits cell migration, possibly contributing to the clinical benefits of chemical AMPK activators in preventing atherosclerosis, vascular remodelling and cancer metastasis. However, the underlying mechanisms remain largely unknown. Here we identify PDZ and LIM domain 5 (Pdlim5) as a novel AMPK substrate and show that it plays a critical r...

Long Term Potentiation (LTP) is a leading candidate mechanism for learning and memory and is also thought to play a role in the progression of seizures to intractable epilepsy. Maintenance of LTP requires RNA transcription, protein translation and signaling through the mammalian Target of Rapamycin (mTOR) pathway. In peripheral tissue, the energy sensor AMP-activated Protein Kinase (AMPK) negat...

Tumor cell proliferation requires both growth signals and sufficient cellular bioenergetics. The AMPactivatedprotein kinase (AMPK) pathway seemsdominant over the oncogenic signaling pathway suppressing cell proliferation. This study investigated the preclinical efficacy of targeting the tumor bioenergetic pathway using a glycolysis inhibitor 2-deoxyglucose (2DG) and AMPK agonists, AICAR andmetf...

BACKGROUND This study was designed to investigate the effect of lycorine (LY) on the AMPK-mTOR-S6K signaling pathway and to clarify its role in autophagy and apoptosis. MATERIAL AND METHODS Various concentrations of LY were used to treat non-small cell lung carcinoma A549 cells. The MTT assay was used to measure cell viability and acridine orange staining was used to detect cell morphology chan...

PURPOSE Metformin is a widely used antidiabetic drug whose anticancer effects, mediated by the activation of AMP-activated protein kinase (AMPK) and reduction of mTOR signaling, have become noteworthy. Chemotherapy produces genotoxic stress and induces p53 activity, which can cross-talk with AMPK/mTOR pathway. Herein, we investigate whether the combination of metformin and paclitaxel has an eff...

Autophagy plays an important role in liver triglyceride (TG) metabolism. Inhibition of autophagy could reduce the clearance of TG in the liver. Hydrogen sulfide (H2S) is a potent stimulator of autophagic flux. Recent studies showed H2S is protective against hypertriglyceridemia (HTG) and noalcoholic fatty liver disease (NAFLD), while the mechanism remains to be explored. Here, we tested the hyp...
