The objective of this study was to evaluate myostatin (MSTN) gene by polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) and sequencing methods in four goat breeds including Mohabadi, Markhoz, Lori and Bital breeds. A573 bp fragment of MSTN gene was amplified by PCR. A new 5 bp deletion in 5`UTR (206TTTTA) of the MSTN gene was directly identified by sequencing. The AA...

Background: Cytokines are cell signaling molecules which upon release by cells facilitate the recruitment of immune-modulatory cells towards the sites of inflammation. Genetic variations in cytokine genes are shown to regulate their production and affect the risk of infectious as well as autoimmune diseases. Intron-3 of interleukin-4 gene (IL-4) harbors 70-bp variable number of tandem repeats (...

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...

different research groups have extensively studied the associations of cytokine gene polymorphisms in different diseases. the role of cytokines gene polymorphisms in multiple sclerosis (ms), as a chronic immune-mediated neurodegenerative disease, has been previously reported in the various populations. for determining pro-inflammatory cytokine gene polymorphisms, 100 relapsing remitting multipl...

wheat is a crop with spring and winter types and wide adaptability to different climate conditions. the wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (vrn) genes play pivotal role in determining spring and winter types. in this study, 395 iranian wheat landraces were characterized with specific primer pairs designed based on vrn-...

dear editor analysis of the phenylalanine hydroxylase (pah mckusick 261600) gene in different populations has revealed more than 320 different mutations associated with phenylketonuria (pku). one of these mutations, ivs10nt546, results in severe pah deficiency due to defective mrna splicing. it accounts for about 40 percent of all mutant alleles in turkish and between 10 to 20 percent of all mu...
