As a well-known phenomenon, total mRNAs poorly correlate to proteins in their abundances as reported. Recent findings calculated with bivariate models suggested even poorer such correlation, whereas focusing on the translating mRNAs (ribosome nascent-chain complex-bound mRNAs, RNC-mRNAs) subset. In this study, we analysed the relative abundances of mRNAs, RNC-mRNAs and proteins on genome-wide s...
The P50 of whole blood [30 ̊C, PCO∑=2.08kPa (15.6mmHg)] decreases during embryonic development from approximately 6.7kPa (50mmHg) at 15 days to about half this value at hatching (86 days), paralleling a decrease in ATP from 100 to 5–10 mmol g21 Hb. There is also a progressive changeover from embryonic to adult haemoglobin (HbA). A pulse of 2,3-diphosphoglycerate (2,3-DPG) (18 mmol g21 Hb) occurs...
More than 300 million people worldwide are chronically infected with hepatitis B virus (HBV). Considering the very short generation time for a virus, and the high error rate associated with the reverse transcription step of HBV replication, decades of HBV infection are probably equivalent to million years of human evolution. The most important selective force during the natural course of HBV in...
Hemoglobin E/β-thalassemia (HbE/β-thalassemia) is the most important type of thalassemia in northeastern Thailand. Serious complications of the disease are associated with iron overload and the consequences of oxidative damage to various organs, especially the cardiovascular system. Endothelial dysfunction is an important predictor for the long-term outcome of the disease. In this study, 19 pat...
We tested the hypothesis that oxidative stress and biological effect after ozone (O3) exposure are dependent on changes in iron homeostasis. After O3 exposure, healthy volunteers demonstrated increased lavage concentrations of iron, transferrin, lactoferrin, and ferritin. In normal rats, alterations of iron metabolism after O3 exposure were immediate and preceded the inflammatory influx. To tes...
The aim of this study was to examine the effects of pyocyanin exposure on mitochondrial GSH, other cellular thiols (thioredoxin-1, Trx-1), and oxidant-sensitive signaling pathways hypoxia inducible factor (HIF-1α) and heme oxygenase (HO-1) in A549 and HBE cell lines. A549 human type II alveolar epithelial cells and human bronchial epithelial (HBE) cells were treated with varying concentrations ...
Polymeric immunoglobulin receptor (pIgR) expression is downregulated in lung cancer, but its implications in lung tumourigenesis remain unknown. We hypothesised that loss of pIgR expression occurs early, and is associated with cell proliferation and poor prognosis. pIgR expression was evaluated by immunohistochemistry in airways of patients with normal mucosa, pre-invasive lesions and invasive ...
Low-dose radiation (LDR) induces hormesis and adaptive response in normal cells but not in cancer cells, suggesting its potential protection of normal tissue against damage induced by conventional radiotherapy. However, the underlying mechanisms are not well established. We addressed this in the present study by examining the role of the ataxia telangiectasia mutated (ATM) signaling pathway in ...
