Ginsenoside Re inhibits pacemaker potentials via adenosine triphosphate-sensitive potassium channels and the cyclic guanosine monophosphate/nitric oxide-dependent pathway in cultured interstitial cells of Cajal from mouse small intestine

open access: yesJournal of Ginseng Research, 2015
Background: Ginseng belongs to the genus Panax. Its main active ingredients are the ginsenosides. Interstitial cells of Cajal (ICCs) are the pacemaker cells of the gastrointestinal (GI) tract.

Peptide-enhanced mRNA transfection in cultured mouse cardiac fibroblasts and direct reprogramming towards cardiomyocyte-like cells. [PDF]

open access: yes, 2015
The treatment of myocardial infarction is a major challenge in medicine due to the inability of heart tissue to regenerate. Direct reprogramming of endogenous cardiac fibroblasts into functional cardiomyocytes via the delivery of transcription factor ...

Cardiomyocyte-Specific Deletion of Sirtuin 5 Accelerates the Development of Heart Failure Upon Dysregulating Purine Metabolism. [PDF]

open access: yesActa Physiol (Oxf)
ABSTRACT Aim Sirtuin 5 (SIRT5), a mitochondrial NAD+‐dependent deacylase, regulates fundamental cellular pathways, including energy substrate metabolism. The current study is designed to better elucidate the role of SIRT5 in the development of heart failure (HF). Methods Mice with cardiomyocyte‐specific deletion (cSirt5−/−) or overexpression (cSirt5‐Tg)

Role of Increased Guanosine Triphosphate Cyclohydrolase-1 Expression and Tetrahydrobiopterin Levels upon T Cell Activation

open access: yesJournal of Biological Chemistry, 2011
Tetrahydrobiopterin (BH4) is an essential co-factor for the nitric-oxide (NO) synthases, and in its absence these enzymes produce superoxide (O2̇̄) rather than NO.

The synthesis of 2′-methylseleno adenosine and guanosine 5′-triphosphates

open access: yesBioorganic & Medicinal Chemistry, 2012
Modified nucleoside triphosphates (NTPs) represent powerful building blocks to generate nucleic acids with novel properties by enzymatic synthesis. We have recently demonstrated the access to 2'-SeCH(3)-uridine and 2'-SeCH(3)-cytidine derivatized RNAs for applications in RNA crystallography, using the corresponding nucleoside triphosphates and distinct

Glucocorticoids and the regulation of phosphoenolpyruvate carboxykinase (guanosine triphosphate) in the rat [PDF]

open access: yesBiochemical Journal, 1975
The effect glucocorticoids on the synthesis and degradation of phosphoenolpyruvate carboxykinase (GTP)(EC4.1.1.32) in rat liver and kidney in vivo was studied immunochemically. The glucocorticoid analogue triamcinolone (9α-fluoro-11β, 21-dihydroxy-16α,17α-isopropylidenedioxypregna-1,4-diene-3,20-dione) increased the synthesis rate of the kidney enzyme ...
