Although cancer cells are frequently faced with a nutrient- and oxygen-poor microenvironment, elevated hexosamine-biosynthesis pathway (HBP) activity protein O-GlcNAcylation (a nutrient sensor) contribute to rapid growth of tumor emerging hallmarks cancer. Inhibiting could be promising anticancer strategy. The gluconeogenic enzyme phosphoenolpyruvate carboxykinase 1 (PCK1) is downregulated in h...
The environment that the cumulus oocyte complex (COC) is exposed to during either in vivo or in vitro maturation (IVM) can have profound effects on the success of fertilisation and subsequent embryo development. Glucose is a pivotal metabolite for the COC and is metabolised by glycolysis, the pentose phosphate pathway (PPP), the hexosamine biosynthesis pathway (HBP) and the polyol pathway. Over...
OBJECTIVE Insulin regulates both glucose uptake and postnatal cardiac growth. The anabolic effects of insulin are mediated by the mammalian target of rapamycin (mTOR), an evolutionarily conserved kinase which is also a convergence point between nutrient sensing and cell growth. We postulated that mTOR signalling in the heart requires the metabolism of glucose. METHODS We interrogated the insu...
taxol is used to treatment of variety cancers including ovarian, breast, lung, head and neck carcinomas and the aids-related karposi’s carcinoma, and was originally obtained from bark of taxus brevifolia. however the amount of extracted taxol from taxus is extremely low and cannot be considered as a suitable commercial source and it has led to studies for finding new sources of taxol. in 1998, ...
introduction: intranodal pathways of atrioventricular (av) node play a vital role in the delay of conduction time in response to various atrial inputs. the present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. methods:...
