the ovine melatonin receptor 1a (mtnr1a) and aromatase (cyp19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in kurdi sheep at kurdi sheep breeding station located in shirvan, iran. the genomic dna was extracted by guanidine thiocyanate-silica gel method. polymerase chain reaction was carried out to amplify 824 bp...

conclusions adeabc efflux system plays a vital role in multidrug resistance in clinical a. baumannii isolates. it was noted that the most important gene responsible for multidrug resistance within this system was the adeb gene especially in carbapenems resistance. methods this study was conducted on 84 multidrug resistant and 13 carbapenem-susceptible a. baumannii isolates obtained from burn an...

background: leishmania, needs to detoxify the macrophage derived potent peroxides (h2o2). tryparedoxin path­way contains tryparedoxin peroxidase (tsa or tryp). the aim of the study was to detect the full-length gene se­quence and its encoded protein of the lmtryp6 gene (eu251502), and comparison the gene sequence with lmtryp6 (lmjf15.1140), another previously reported member of this gene family...

objective: breast cancer is one of the most common malignancies in women worldwide. it is caused by a number of genetic and epigenetic factors. aberrant hypermethylation of the promoter regions in specific genes is a key event in the formation and progression of breast cancers as well as the dbc2 gene, as a tumor suppressor gene. different studies show that the dbc2 gene is inactivated through ...

Quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. Reports name the acyl coA: diacylglycerol acyltransferase (DGAT1) gene as a potential candidate gene with dinucleotide substitution (AA to GC) in exon VIII which causes the change of lysine to alanine in amino acid (K232A).The aim of the present study was to estimate the frequency...

background and objectives: phosphlipases are a group of enzymes that breakdown phosphatidylcholine (phospholipids) molecules producing second products. these produced products have a divers role in the cell like signal transduction and digestion in humans. in this research the effect of phosphatidylcholine on the expression of plc genes of a. fumigatus was studied. the plc genes of this fungus ...

plants face many biotic and abiotic stresses at the same time during their growth under field conditions. plants responses toward combined stresses are often more complex than their responses to one type of stress in a way that the results of these responses are called as cross tolerance. this mixture of stresses activates specific models of gene expression that causes special signaling network...
