We previously reported that fatty acid-bearing albumin but not fatty acid-depleted albumin induces hypoxia-inducible factor-1 (HIF-1) activation in human renal proximal tubular epithelial cell line HK-2. Then, an increase in mRNA expression of peroxisome proliferator-activated receptor gamma (PPARγ)
OBJECTIVE
A high-rate glycolysis is a fundamental property of solid tumors and is associated with an over-expression of glucose transporters and glycolytic enzymes. We hypothesize that over-expression of glucose transporters in tumors prevents apoptosis, promotes cancer cell survival, and confers
Mechanisms of proton conductance (GH) were investigated in phospholipid bilayer membranes containing long-chain fatty acids (lauric, myristic, palmitic, oleic or phytanic). Membranes were formed from diphytanoyl phosphatidylcholine in decane plus chlorodecane (usually 30% vol/vol). Fatty acids were
The evidence suggests that glucose transport across the blood brain barrier (BBB) in the dog is normally not a rate-limiting step in cerebral metabolism; however, transport may become rate-limiting under conditions of extreme hypoglycemia or anoxia. Studies on the mechanism of glucose transport from
Adipose tissue (AT) expansion induces local hypoxia, a key contributor to the chronic low-grade inflammation that drives obesity-associated disease. Apple flavonols phloretin (PT) and phlorizin (PZ) are suggested anti-inflammatory molecules but their effectiveness in obese AT is inadequately
Using a new, in vitro, experimental approach the transport of glucose, galactose, fructose and glycine in seroso-mucosal direction in the small intestine, was studied under different modes of oxygenation. In case of monosaccharides under the oxygenation from serosal surface, the substrate
OBJECTIVE
Are the placental aquaporins (AQPs) involved in the apoptosis of human trophoblast?
UNASSIGNED
The general blocking of placental AQPs with HgCl2 and, in particular, the blocking of AQP3 activity with CuSO4 abrogated the apoptotic events of human trophoblast cells.
BACKGROUND
Although
Osteosarcoma is the most common primary malignancy of bone. Even after the traditional standard surgical therapy, metastasis still occurs in a high percentage of patients. Glucose is an important source of metabolic energy for tumor proliferation and survival. Tumors usually overexpress glucose
The water channel, Aquaporin-9 (AQP9) is enriched in selected neuronal populations and is unique its ability to act as a lactate-glycerol channel supplying neurons with alternative fuel under ischaemic conditions. AQP9 was detected in RGC-5 cells, a retinal ganglion cell-line, primary RGCs, and
