The purpose of this study was to elucidate whether exogenous nitric oxide (NO) has a potential beneficial effect on lipase production capacity of some microorganisms. Sodium nitroprusside (SNP) was used as an exogenous NO donor in production medium. In comparison with the control (0 nM SNP), SNP concentrations from 10 to 100 nM induced lipase production in mesophilic bacterium Bacillus subtilis and cold-adapted yeast Yarrowia lipolytica. Especially, the maximum lipase activities for Y. lipolytica (81.2 U/L) and B. subtilis (74.5 U/L) were attained at 30 and 50 nM SNP concentrations, respectively. When compared to the control, the optimal SNP concentrations resulted in about 5.14 and 2.27-fold increases in lipase activities of B. subtilis and Y. lipolytica, respectively. Besides, it was found that the optimal SNP concentrations provided shorter incubation periods for lipase production. Conversely, no significant positive effect of exogenous NO on lipase production was determined for thermophilic bacterium Geobacillus stearothermophilus. This study showed for the first time that exogenous NO could be used as an inducer in the production of microbial lipases. 相似文献

Adriamycin (ADR) increases the production of reactive oxygen species (ROS), which diminishes mitochondrial function. Angiotensin-II stimulates mitochondrial ROS generation. The aim of the study was to examine whether angiotensin converting enzyme (ACE) or renin inhibitors protect against ADR-induced mitochondrial function impairment. Rats were divided into five groups as control, ADR, co-treatment ADR with captopril, co-treatment ADR with aliskiren, co-treatment ADR with both captopril and aliskiren. Left ventricular function and blood pressures were assessed at the end of treatment period. Mitochondrial membrane potential (MMP) and ATP levels were determined. ADR treatment decreased the left ventricular pressure and increased the left ventricular end-diastolic pressure. ADR decreased MMP and ATP levels in myocyte mitochondria due to increasing oxidative stress. ADR decreased MMP and ATP levels due to increased oxidative stress in the heart. Inhibitors of ACE and renin caused the elevation of the decreased of MMP and ATP levels. The pathologic changes in electrocardiogram, blood pressure and left ventricular function were decreased by inhibition of Ang-II production. We concluded that inhibitors of angiotensin II are effective against ADR cardiotoxicity via the restoration of MMP and ATP production and prevention of mitochondrial damage in vivo. 相似文献

When working on an ongoing genome sequencing and assembly project, it is rather inconvenient when gene identifiers change from one build of the assembly to the next. The gene labelling system described here, UniqTag, addresses this common challenge. UniqTag assigns a unique identifier to each gene that is a representative k-mer, a string of length k, selected from the sequence of that gene. Unlike serial numbers, these identifiers are stable between different assemblies and annotations of the same data without requiring that previous annotations be lifted over by sequence alignment. We assign UniqTag identifiers to ten builds of the Ensembl human genome spanning eight years to demonstrate this stability. The implementation of UniqTag in Ruby and an R package are available at https://github.com/sjackman/uniqtag sjackman/uniqtag. The R package is also available from CRAN: install.packages ("uniqtag"). Supplementary material and code to reproduce it is available at https://github.com/sjackman/uniqtag-paper. 相似文献

The genus Crataegus is well distributed in Turkey as a wild plant, with numerous, inherently variable species and genotypes. RAPD markers were used to study 17 hawthorn genotypes belonging to Crataegus monogyna ssp. monogyna Jacq (2 genotypes), C. monogyna ssp. azarella Jacq (1), Crataegus pontica K.Koch (3), Crataegus orientalis var. orientalis Pallas Ex Bieb (3), Crataegus pseudoheterophylla Pojark (1), Crataegus aronia var. dentata Browicz (1), C. aronia var. aronia Browicz (4), and Crateagus × bornmuelleri Zabel (2). The 10 RAPD primers produced 72 polymorphic bands (88% polymorphism). A dendrogram based on Jaccard’s index included four major groups and one outgroup according to taxa. The lowest genetic variability was observed within C. aronia var. aronia genotypes. The study demonstrated that RAPD analysis is efficient for genotyping wild-grown hawthorns. 相似文献
