calpastatin polymorphism and its association with daily gain in kurdi sheep

چکیده
association of genetic polymorphism in the calpastatin (cast) gene with average daily gain was examined in iranian purebred kurdi sheep. the genotypes for cast were determined by the pcr-sscp method. blood samples were collected from 84 purebred kurdi sheep belonging to the kurdi breeding station located in the khorasan province, north-east of iran. extraction of genomic dna was based on the guanidinium thiocyanate-silica gel method. three genotypes including aa, ab and ac with frequencies of 0.55, 0.32 and 0.13, were observed in this population. chi-square test confirmed hardy-weinberg equilibrium for the cast loci. average heterozygosity (37%) of the cast locus for kurdi sheep was slightly low. daily gain birth to weaning (gbw); weaning to six months (gws); six to nine months (gsn) and nine to yearling (gny) were analyzed by a statistical model comprising sscp (single strand conformation polymorphism) and significant effect (p

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region
چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

The influence of melatonin receptor 1A gene on litter size was studied in 150 ewes from Zel (n=100) and Naeini (n=50) sheep breeds. Two restriction fragment length polymorphism (RFLP) analyses were done to determine all genotypes occurring by variations at MnlI and RsaI restriction sites. The M and C were the most frequent alleles in both of these breeds. The MM genotype was predominant in Zel ...
