Makhosazane Zungu et al.
The American journal of pathology, 178(1), 4-11 (2011-01-13)
The 5'-AMP-activated protein kinase (AMPK) functions as a metabolic fuel gauge that is activated in response to environmental stressors to restore cellular energy balance. In the heart, AMPK coordinates the activation of glucose and fatty acid metabolic pathways to ensure
Tomohito Fujimoto et al.
Biochemical and biophysical research communications, 410(1), 45-51 (2011-06-07)
Ca(2+)/calmodulin-dependent protein kinase kinase (CaMKK) phosphorylates and activates specific downstream protein kinases including CaMKI, CaMKIV and 5'-AMP-activated protein kinase. In order to examine the variety of CaMKK-mediated signaling pathways, we searched for novel CaMKK substrate(s) using N(6)-(1-methylbutyl)-ATP and genetically engineered
Lin Huang et al.
Nucleic acids research, 48(13), 7545-7556 (2020-06-11)
While most SAM riboswitches strongly discriminate between SAM and SAH, the SAM/SAH riboswitch responds to both ligands with similar apparent affinities. We have determined crystal structures of the SAM/SAH riboswitch bound to SAH, SAM and other variant ligands at high
Ming Gan et al.
Neurobiology of aging, 36(2), 1209-1220 (2014-12-07)
The pathologic hallmark of Parkinson's disease (PD) is the accumulation of alpha-synuclein (αsyn) in susceptible neurons in the form of Lewy bodies and Lewy neurites. The etiology of PD remains unclear. Because brain injury has been suggested to facilitate αsyn
S Eric Nybo et al.
Purinergic signalling, 15(1), 17-25 (2019-01-04)
Purine metabolites have been implicated as clinically relevant biomarkers of worsening or improving Parkinson's disease (PD) progression. However, the identification of purine molecules as biomarkers in PD has largely been determined using non-targeted metabolomics analysis. The primary goal of this
Giorgia Zadra et al.
Clinical cancer research : an official journal of the American Association for Cancer Research, 16(13), 3322-3328 (2010-04-29)
Although the role of metabolic syndrome (MS) and a high fat diet in prostate cancer (PCa) risk is still a matter of intense debate, it is becoming increasingly clear that obesity can cause perturbations in metabolic pathways that contribute to
Misaki Kawanishi et al.
Biomedical chromatography : BMC, 29(9), 1309-1316 (2015-01-28)
Monitoring of pharmacodynamics in addition to pharmacokinetics is one of strategies to individualize mycophenolate mofetil therapy. The purpose of this study was to develop sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for evaluation of the pharmacokinetics and pharmacodynamics of mycophenolic
Christos D Georgiou et al.
Redox biology, 17, 128-142 (2018-04-24)
A new 2,4-dinitrophenylhydrazine (DNPH)-based photometric assay is developed for the quantification of carbonyls in protein samples from any biological source by protein carbonyl-DNPH hydrazone formation at acidic pH in the presence of denaturing urea, and subsequent hydrazone solubilization in the
Yugo Tsuchiya et al.
Bioscience reports, 32(2), 197-213 (2011-08-20)
In adult rat cardiac myocytes adrenaline decreased AMPK (AMP-activated protein kinase) activity with a half-time of approximately 4 min, decreased phosphorylation of AMPK (α-Thr172) and decreased phosphorylation of ACC (acetyl-CoA carboxylase). Inactivation of AMPK by adrenaline was through both α1- and
Ziyun Wu et al.
Cell metabolism, 29(5), 1192-1205 (2019-03-25)
Chronic inflammation predisposes to aging-associated disease, but it is unknown whether immunity regulation might be important for extending healthy lifespan. Here we show that in C. elegans, dietary restriction (DR) extends lifespan by modulating a conserved innate immunity pathway that is
Shudong Liu et al.
PloS one, 10(5), e0124951-e0124951 (2015-05-02)
Our previous study found that thyroid-stimulating hormone promoted sterol regulatory element-binding protein-2 (SREBP-2) expression and suppressed AMP-activated protein kinase (AMPK) activity in the liver, but it was unclear whether there was a direct link between TSH, AMPK and SREBP-2. Here
Min-Jung Kim et al.
Retrovirology, 12, 90-90 (2015-11-08)
The human immunodeficiency virus type-1 (HIV-1) nucleocapsid protein (NC) is an essential and multifunctional protein involved in multiple stages of the viral life cycle such as reverse transcription, integration of proviral DNA, and especially genome RNA packaging. For this reason
