The aims of the present study were (i) to develop and test a sensitive and reproducible method for the study of gene expression in staphylococci and (ii) to study the expression of five housekeeping genes which are involved in nucleic acid metabolism (gmk, guanylate kinase; the dihydrofolate reductase [DHFR] gene), glucose metabolism (tpi, triosephosphate isomerase), and protein metabolism (the...
BACKGROUND The chicken is an important agricultural and avian-model species. A survey of gene expression in a range of different tissues will provide a benchmark for understanding expression levels under normal physiological conditions in birds. With expression data for birds being very scant, this benchmark is of particular interest for comparative expression analysis among various terrestrial...
Injury to the peripheral nerve induces dramatic changes in terms of cellular composition that are reflected on RNA quality and quantity, making messenger RNA expression analysis very complex. Several commonly used housekeeping genes are regulated following peripheral nerve injury and are thus not suitable for quantitative real-time PCR normalization; moreover, the presence of pseudogenes in som...
Results of overexpression or downregulation of a microRNA (miRNA) on its target mRNA expression are often validated by reverse-transcription and quantitative PCR analysis using an appropriate housekeeping gene as an internal control. The possible direct or indirect effects of a miRNA on the expression of housekeeping genes are often overlooked. Among many housekeeping genes, expressions of glyc...
Human tissue-specific genes were reported to be longer than housekeeping genes (both in coding and intronic parts). The competing neutralist and adaptationist models were proposed to explain this observation. Here I show that in human genome the longest are genes with the intermediate expression pattern. From the standpoint of information theory, the regulation of such genes should be most comp...
Total RNA was extracted from 105 individual postmortem human brain samples representing a range of postmortem conditions. To improve upon parameters currently used to screen for RNA quality, electropherogram patterns generated by the Agilent Bioanalyzer 2100 were compared to the average score in random hexamer-primed reverse transcription real-time PCR for four housekeeping genes in each RNA sa...
Molecular typing of Neisseria gonorrhoeae strains is an important tool for epidemiological studies of gonococcal infection and transmission. The recently developed multilocus sequence typing (MLST) method is based on the genetic variation among housekeeping genes. As a preliminary investigation for the development of such a method, we characterized the genetic diversity at 18 gonococcal houseke...
Background and Objective: In the last few decades, organizational factors have become the leading indicators of occupational health and safety (OHS) performance in industries. ELMERI is a simple and cost-effective method for monitoring OHS performance in the manufacturing industries. Regrading this, the present study was carried out to evaluate the safety and health performance in a steel indus...
Preeclampsia and diabetes are complications of pregnancy that contribute to maternal and perinatal mortality worldwide. Results emerging from molecular studies of placentae may elucidate etiologically important genomic alterations. Appropriate application of real time reverse transcription (RT) PCR in comparative gene expression studies requires endogenous housekeeping genes to normalize betwee...
the aim of the present study was to investigate the relationship between job burnout and sources of stress and coping strategies in the referees of iran premier league. 103 referees were selected as the sample. sources of stress inventory (voight, 2009), mbi (maslach & jackson, 1996) and wcq (billings & moos, 1981) were used to collect data. results showed a significant relationship between con...
