Tyrosyl-tRNA synthetase (TyrRS) is well known for its essential aminoacylation function in protein synthesis. Recently, TyrRS has been shown to translocate to the nucleus and protect against DNA damage due to oxidative stress. However, the mechanism of TyrRS nuclear localization has not yet been determined. Herein, we report that TyrRS becomes highly(More)
Recently, increasing studies have documented that tumorigenesis closely relates to apoptotic processes. Thus, inducing apoptosis is an anti-cancer strategy against osteosarcoma. Here we investigated the anti-proliferative effect of calycosin on human osteosarcoma cell (143B) in vitro. The results showed that calycosin dose-dependently inhibited 143B cell(More)
Sulfide is a natural, widely distributed, poisonous substance. Sulfide: quinone oxidoreductase (SQR) is responsible for the initial oxidation of sulfide in mitochondria. To study transcriptional regulation of sqr after sulfide exposure, a 2.6-kb sqr upstream sequence from echiuran worm Urechis unicinctus was cloned by genome walking. Bioinformatics analysis(More)
BACKGROUND Sulfide is a well-known environmental toxic substance. Mitochondrial sulfide oxidation is a main mechanism of sulfide detoxification in organisms, and sulfide: quinone oxidoreductase (SQR) is a key enzyme which is involved in transferring electrons from sulfide to ubiquinone and converting sulfide into thiosulfate. Previous studies have revealed(More)
OBJECTIVE To explore the role of ZNF217 in regulating cell proliferation, migration and invasion in glioma cells. METHDOS A lentivirus-mediated shRNA-ZNF217 vector was infected into glioma U251 cells, and the interference efficiency was examined by Western blotting. MTT assay, flow cytometry, Transwell assay, and Boyden chamber assay were used to analyze(More)
Primary cultured cells can be a useful tool in studies on physiology, virology, and toxicology. Hemocytes play an important role in animal rapid response to pathogen invasion. In this study, an appropriate medium for primary culture of hemocytes of the bivalve Chlamys farreri was developed by adding 5% fetal bovine serum and 1% C. farreri serum to Leibovitz(More)
BACKGROUND Exercise is important for fitness and recovery of older adults after hospitalization for treatment of cardiovascular disease. Home-based, nurse-led exercise programs may be beneficial. OBJECTIVE The aim of this study was to test the effects of a low-intensity, home-based exercise protocol led by an advanced practice nurse on health-related(More)
OBJECTIVE To investigate whether cellular immunity and humoral immunity are involved in trichlorethylene (TCE)-induced mixed allergy, then provide the scientific basis for the mechanism of this disease. METHODS Guinea pigs and rats were tested for this study by application of guinea pig maximization test (GPMT), the animals were randomly divided into(More)
Insecticide deltamethrin resistance has presented a difficult obstacle for pest control and the resistance development is complex and associated with many genes. To better understand the possible molecular mechanisms involved in DM stress, in this study, cDNA microarray analysis was employed. 448 differentially expressed genes with at least a 2-fold(More)
