Triiodothyronine administration before partial hepatectomy increased the activity of mitochondrial glycerophosphate cytochrome c reductase. The enzyme activity was further activated after partial hepatectomy during the regenerative process. Our findings showed that: a) the increase of glycerophosphate cytochrome c reductase induced by triiodothyronine was further potentiated by the regeneration...

Piper sarmentosum or ‘kaduk’ is a well-known herb plant in Malaysia. Its extracts were found to exhibit bone-protective effect against osteoporotic rats. Our study aim morphologically observe the of P. ethyl acetate extract on differentiation human peripheral blood stem cells (PBSCs) into osteoblasts. (1-900 µg/mL) prepared using 1% dimethyl sulfoxide (DMSO) used cytotoxicity assay. Then, assay...

Xenopus laevis oocytes were microinjected with low molecular weight phosphoesters such as 2-glycerophosphate, phosphotyrosine, phosphoserine, phosphothreonine, 4-nitrophenyl phosphate, and orthophosphate. These compounds were able to induce a considerable reduction in the time course of progesterone-induced maturation, with 2-glycerophosphate being the most effective. The basal level of cAMP an...

Data presented in this paper show that the size of the endogenous coenzyme Q (CoQ) pool is not a limiting factor in the activation of mitochondrial glycerophosphate-dependent respiration by exogenous CoQ(3), since successive additions of succinate and NADH to brown adipose tissue mitochondria further increase the rate of oxygen uptake. Because the inhibition of glycerophosphate-dependent respir...

We studied the extent to which hormonally-induced mitochondrial glycerophosphate dehydrogenase (mGPDH) activity contributes to the supply of reducing equivalents to the mitochondrial respiratory chain in the rat liver. The activity of glycerophosphate oxidase was compared with those of NADH oxidase and/or succinate oxidase. It was found that triiodothyronine-activated mGPDH represents almost th...

Osteoprotegerin (OPG), receptor activator of NF-κB ligand (RANKL)/receptor activator of NF-κB (RANK) axis, and TNF-related apoptosis-inducing ligand (TRAIL) participate in vascular calcification process including atherosclerosis, but their contributions under high glucose (HG) and phosphate (HP) condition for a long-term period (more than 2 weeks) have not been fully determined. In this study, ...

The rates of activity of the dehydrogenase systems in Tetrahymena, which are concerned with carbohydrate oxidation, in descending order of activity are: lactic > isocitric > succinic = glucose > glucose-6-phosphate = 6-phosphogluconic = malic > glutamic = cytochrome linked alpha-glycerophosphate dehydrogenase. No evidence was obtained to indicate the presence of DPN linked alpha-glycerophosphat...
