  Genotypes of Iranian Zel sheep for Calpastatin(CAST) locus were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) methods and for Calpain(CAPN) locus by PCR-SSCP. Blood samples were collected from 200 purebred Zel sheep of Zel Breeding Station located in Golestan province in northeast of Iran. Extraction of genomic DNA was based on modified salting out method. The digestion of PCR products of CAST gene by MspI and NcoI restriction enzymes revealed two alleles M and N, with frequencies 85.5 and 14.5%, respectively. Frequencies were 75, 21 and 4% for MM, MN and NN genotypes, respectively. Alternatively, using PCR-SSCP method, four genotypes including AA, AB, BB and AC with frequencies of 71, 21, 4 and 4%, respectively, were observed in this population. Analyzing CAPN gene by the PCR-SSCP method, revealed two different conformational patterns (AA and AB) with frequencies of 69 and 31% for AA and AB, respectively. Average heterozygosity for both loci was low (0.28 and 0.25% for CAST using PCR-SSCP and PCR-RFLP, and 0.26% for CAPN).Yearling weights (YW) were analyzed by a statistical model comprising PCR-SSCP and as a result CAPN genotypes had significant effect (P<0.01) on YW. A Chi-square test confirmed Hardy-Weinberg (H-W) equilibrium for the CAST locus using PCR-SSCP method but not for PRC-RFLP method and CAPN locus. Totally, the investigated herd had little genetic diversity and different factors disturb H-W equilibrium and PCR-RFLPand PCR-SSCP might be used successfully in these studies. تفاصيل المقالة

  The goal of this study was investigation of the calpastatin gene polymorphism and its effect on early body weight traits in Zandi sheep by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method. Calpastatin is the main inhibitors of calpain-calpastatin enzyme system that play an important role in regulating the protein regeneration process. Genomic DNA was extracted by whole blood samples from 124 randomly selected Zandi breed sheep using salting out method. Birth weight, weight on 150 days old and daily weight gain from birth to 150 days old were recorded. The exon and intron 1 of ovine calpastatin gene were amplified to produce a 622 bp fragment. The PCR products were digested with MspI restriction enzyme and electrophoresised on agarose gel. Results showed 80.6% and 19.4% allele frequencies for A and B alleles and 65.32%, 4.04% and 30.64% genotype frequencies for AA, BB and AB genotypes, respectively. X2 and G2 tests showed the Hardy-Weinberg equilibrium for studied locus. The effect of calpastatin genotype on growth traits was insignificant, but genotype BB had the best performance among all the three traits, which indicates the better performance of normal allele (B) than mutant allele (A) for these traits. تفاصيل المقالة

  Calpastatin gene has been known as a candidate gene for meat quality in cattle, sheep, and chicken. The purpose of this study was to identify CAST gene polymorphisms and its association with meat traits in Boerka goat. The data of pH, cooking loss (CL), warner-bratzler shear force (WBSF), water holding capacity (WHC), cholesterol, water, ash, fat, and protein contains were recorded. Sequencing of 21 samples revealed five polymorphisms of CAST gene in intron 12 within Boerka goat, namely g.146C > A, g.224A > G, g.281G > A, g.737C > T, and g.431G > A. Only single nucleotide polymorphism (SNP) g.281G > A was used for genotyping. The genotype and allele frequency based on g.281G > A showed 14.29% (GG genotype) and 85.71% (GA genotype) followed with 57% G allele and 43% A allele. The chi-square test showed deviation from HWE (p <0.05) in Boerka goat. The SNP g.281G > A revealed having significantly effect to CL. The GA animals had lower CL percentage compared to the GG animals. In conclusion, the SNP selected may be used for identify meat having low CL in Boerka goat. تفاصيل المقالة

  Restriction fragment length polymorphisms (RFLP) have been identified at the goat. The objective of the present study was to determine polymorphisms of calpastatin locus in Raini and Tali goats of the goats in Kerman Province, improving meat quality traits superior meat quality by selection. Calpastatin gene effect on quality and tenderness meat, to identify different genotype of this gene was randomly selected 150 Tali and 150 Raini goats, and blood samples were collected from total of animals using ethylenediaminetetraacetic acid (EDTA) tubes. DNA was extracted from blood according to DNA preparation kit to determine the genetic relationship among studied goat animals. Amplification was performed using polymerase chain reaction (PCR). Two alleles (A and B) and three genotypes, (AA, BB and AB) were observed. The frequencies of the observed genotypes for Tali and raini were 38.4, 9.6, 52 and 17, 71, 12 for AA, BB and AB, respectively. And allele frequencies were 0.47, 0.53 and 0.12, 0.88 for A and B, in Tali and Raini goats respectively. تفاصيل المقالة

  کالپاستاتین نقش تنظیمی در رشد ماهیچه‌ها و تردی گوشت بعد از کشتار دام دارد که ژن کنترل کننده آن بر روی کروموزوم شماره 5 گوسفند جای گرفته است. ارتباط برخی از شکل های آللی این ژن با افزایش وزن و صفات لاشه در گوسفند کشف شده است که این امر در نتیجه جانشینی ساده 1 نوکلئوتید در اگزون I ژن کالپاستاتین است که با تکنیک RFLP با آنزیم های برشی MspI و یا NcoI تشخیص داده می‌شود و می‌تواند به عنوان نشان گری در جهت اصلاح نژاد به کار گرفته شود. هدف از این تحقیق بررسی تنوع ژنتیکی ژن کالپاستاتین در گوسفند با روش MspI/RFLP است. در این تحقیق نمونه‌های خون از 137 رأس گوسفند (65 رأس گوسفند قزل، 42 رأس گوسفند آرخامرینو و 30 رأس گوسفند آمیخته آرخامرینو× قزل) جمع‌آوری گردید. DNA ژنومی از 50 میکرولیتر خون با روش سیلیکاژل استخراج گردید و برای ارزیابی کیفیت و کمیت DNA روش های ژل مونیتورینگ و اسپکتروفوتومتری مورد استفاده قرار گرفت. پس از استخراج DNA ژنومی، تکثیر ناحیه چندشکل ژن کالپاستاتین به طول 570 جفت باز با آغازگرهای اختصاصی Ovine Calp-F و Ovine Calp-R صورت گرفت. جهت برش آنزیمی قطعات DNA تکثیر شده، از آنزیم MspI استفاده گردید. محصولات هضم شده، بر روی ژل آگارز 5/1% الکتروفورز شده و با اتیدیوم‌بروماید رنگ‌آمیزی گردید. پس از تعیین ژنوتیپ تمامی نمونه‌های مورد مطالعه، از نرم‌افزار Popgene 1.32 برای بررسی آماری داده‌ها استفاده گردید که فراوانی آلل M در گوسفند قزل 69%، گوسفند آرخامرینو 48%، و آمیخته‌های F1 این دو نژاد 50% به دست آمد. بر اساس نتایج این مطالعه، جمعیت های مورد مطالعه در تعادل هاردی- واینبرگ قرار داشتند و این نشان می دهد که در جمعیت های گوسفندان مورد مطالعه، انتخاب ژنتیکی در راستای اصلاح نژاد برای ژن کالپاستاتین صورت نگرفته است. تفاصيل المقالة
