OTUB1 (OTU deubiquitinase, ubiquitin aldehyde binding 1) is a deubiquitinating enzyme (DUB) that belongs to the OTU (ovarian tumor) superfamily. The aim of this study was to clarify the role of OTUB1 in colorectal cancer (CRC) and to identify the mechanism underlying its function. Two hundred and sixty CRC samples were subjected to association analysis of(More)
A replication-deficient adenovirus (Ad) encoding secreted human endostatin (Ad-Endo) has been demonstrated to have promising antiangiogenic and antitumoral effects. The E1B55k-deleted Ad H101 can selectively lyse cancer cells. In this study, we explored the antitumor effects and cross-interactions of Ad-Endo and H101 on nasopharyngeal carcinoma (NPC). The(More)
In this study, we tried to explore if xeroderma pigmentosum complementation group-A (XPA) expression is likely a prognostic prediction factor for locally advanced nasopharyngeal carcinoma (NPC) patients treated with platinum-based chemoradiotherapy, which was considered to bring chemotherapy-related severe toxicity compared with radiotherapy alone. Firstly,(More)
Gene therapy using a recombinant adenovirus (Ad) encoding secretory human endostatin (Ad-Endo) has been demonstrated to be a promising antiangiogenesis and antitumor strategy of in animal models and clinical trials. The E1B55KD-deficient Ad dl 1520 was also found to replicate selectively in and destroy cancer cells. In this study, we aimed to investigate(More)
OBJECTIVE Using the stable isotopes as the internal standard of microdialysis technology to establish a new method to study the whole and local brain dynamics of nicotine percutaneous preparations. METHOD Using th healthy rats as experimental animals, administrating nicotine in abdominal transdermal way, then sample in the blood and brain simultaneously(More)
BACKGROUND Ankyrin repeat and SOCS box protein 3 (ASB3) is a member of ASB family and contains ankyrin repeat sequence and SOCS box domain. Previous studies indicated that it mediates the ubiquitination and degradation of tumor necrosis factor receptor 2 and is likely involved in inflammatory responses. However, its effects on oncogenesis are unclear. This(More)
Volatile fatty acids (VFA), the substrate for the bio-methane yield, can be generated from excess sludge or herbaceous plant waste during the anaerobic fermentation process. However, due to the high protein content and the low carbon-to-nitrogen (C/N) ratio of excess sludge, the nutrient utilization of excess sludge to generate VFA and bio-methane usually(More)
Since the shelterbelt systems of 1,092,260 hm2 have been established for thirteen years from 1978, have formed 526,541 networks and protected 13,619,400 hm2 land in western part of Northeast region of China. According to the research work we did in the last five years, the results of research project showed that the shelterbelts had improved the environment(More)
The paper is to report the study of pharmacokinetics of transdermal administered nicotine in the brain of freely moving rat by using microdialysis with stable labeled isotope as internal standard. The pharmacokinetic behavior of nicotine in Sprague Dawley rat brain was investigated after intranasal administration (3.75 mg). Brain fluid samples were(More)
5-aminolevulinic acid (ALA) is an essential precursor for the biosynthesis of tetrapyrrols such as heme and chlorophyll (Chl). Previous studies have focused mainly on promotive effects of exogenous ALA on plant growth, while regulatory mechanisms affecting Chl biosynthesis have been only partially discussed. In the present study, the ameliorative role of(More)
