Genetic polymorphism of the kappa-casein gene in Brazilian cattle.
Frequencies of kappa-casein gene alleles were determined in 1316 animals from the Brazilian Bos indicus genetic groups (Sindhi cows, Gyr sires, Gyr cows, Guzerat sires, Guzerat cows, Nellore sires, and Gyr x Holstein crossbreds) by means of polymerase chain reaction-restriction fragment length polymorphism analysis using two independent restriction nucleases (Hinf I and HaeIII). The genotyping ...
متن کاملExpected Progeny Difference (EPD) in Beef Cattle
The first performance records of beef cattle were primarily weights or weight gains measured at weaning or yearling ages. Sound comparisons of individuals were often impossible because of sources of variation, such as age, sex, age of dam, and management conditions. Although standard adjustments were developed to account for some of these variations, this was not always possible, especially for...
متن کاملInvestigation of Kappa Casein Gene Polymorphism by PCR-RFLP in Najdi Cattle Breed Population in Khuzestan Province
More than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. Kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. The present study describes polymorphism of kappa casein gene. This is the first study of kappa casein gene polymorphism in Najdi cattle of Iran. We used the polymerase chain r...
متن کاملAssociation of Kappa-Casein Gene Polymorphism with some Biochemical Blood Indicators in Guilan Native Cattle of Iran (Bos indicus)
Evaluation of the blood and milk biochemical parameters always is considered as effective key factor for animal health and dairy products. In order to assess the association of kappa-casein (K-CN) genetic variants with blood biochemical indicators, blood samples were randomly and individually collected from 126 Iranian Guilan native cattle. Blood plasma was used to measure blood glucose, urea, ...

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...
