OBJECTIVE To study the expression of hypoxia-inducible factor 1 alpha (HIF-1 alpha) and vascular endothelial growth factor (VEGF) in prostate cancer (PCa) and its biological significance. METHODS Specimens from 75 patients with PCa (32 cases), benign prostatic hyperplasia (BPH, 16 cases), high-grade prostate intraepithelial neoplasia (PIN, 15 cases) and(More)
Protein N-glycosylation (PNG) is crucial for protein folding and enzymatic activities, and has remarkable diversity among eukaryotic species. Little is known of how unique PNG mechanisms arose and evolved in eukaryotes. Here we demonstrate a picture of onset and evolution of PNG components in Golgi apparatus that shaped diversity of eukaryotic protein(More)
OBJECTIVE To investigate the changes of pulmonary tissue area density and their mechanisms in rats with hypoxic pulmonary hypertension (HPH). METHODS 54 Wistar rats were divided into hypoxia 10 d (n = 12), 20 d (n = 12), 30 d (n = 12) groups and control group (n = 18). The rats in hypoxia groups were exposed to a simulated hypoxia environment at a height(More)
