The relationship between cell membrane damage and lipid peroxidation under the condition of hypoxia-reoxygenation: analysis of the mechanism using antioxidants and electron transport inhibitors.

30 Jul 2009 We consecutively observed lipid peroxidation and cell membrane damage under the condition of hypoxia-reoxygenation (H/R) in cells and analyzed their mechanisms by using electron transport inhibitors and an antioxidant. In H/R experiments, lipid ... Read more...

Oxygen-regulated beta(2)-adrenergic receptor hydroxylation by EGLN3 and ubiquitylation by pVHL.

5 Jul 2009 Agonist-induced ubiquitylation and degradation of heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors (GPCRs) play an essential role in surface receptor homeostasis, thereby tuning many physiological processes. Although ... Read more...

Ontogenetic development of erythropoiesis can be studied non-invasively in GATA-1:DsRed transgenic zebrafish.

3 Jul 2009 For the erythroid cell lineage development in vertebrates, GATA-1 transcription factor is essential. In our report, we have demonstrated that the approximate developmental status of erythrocytes and the progression of blood formation can be studied ... Read more...
