background: the induction of brain-derived neurotrophic factor (bdnf) expression in the hippocampus has shown to play a role in the beneficial effects of resveratrol (rsv) on the learning and memory. the bdnf gene has a complicated structure with eight 5’ noncoding exons (i-ixa), each of which can splice to a common coding exon (ix) to form a functional transcript. estrogens increase levels of ...

stearoyl-coa desaturase (scd) is a rate-limiting enzyme in the biosynthesis of monounsaturated fatty acids (mufa). a number of studies support the hypothesis that scd gene regulation and polymorphism may affect fatty acid composition and fat quality in meat and milk. single nucleotide polymorphisms in the coding region of the bovine stearoyl-coa desaturase gene have been predicted to result in ...

Objective: Diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. The objective of this project is to check out the polymorphism at the exon 8 region of DGAT1 gene using PCR-SSCP technique in Iranian water buffaloes (Bubalus bubalis). Recent activities have shown that a significant association between lysine at amino acid positi...

In Iraq generally and Kurdistan region specifically, goats are an important resource for meat milk production. It is well known that Myostatin genes (MSTN) have the essential role in growth development due to its crucial involvement muscle growth. The goal of this research was reveal polymorphism MSTN gene different Capra hircus breeds (native, Shami, Meriz Kamori goat) wild mountain goat (Capr...

Background: Unexplained recurrent spontaneous abortion (URSA) has been suggested being associated with the failure of fetal-maternal immunologic tolerance in which the regulatory T lymphocytes (Tregs) play a crucial role. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is expressed transiently on activated T cells and constitutively on Tregs. CTLA-4 interacts with the B7 cell surface molec...

The metallothionein (MT) system has been used to analyze the structural features associated with the control of gene expression (1). A pre-requisite for this type of analysis is knowledge of the primary DNA sequence. We have isolated a clone containing the Chinese hamster MT I gene from a Charon 4A EcoRI total digest prepared from a Chinese hamster cell line amplified for the MT genes (XCH 4A-H...

The ABCA1 transporter is one of the limiting steps in cellular cholesterol efflux. To study the expression and activity of the human ABCA1 gene in vivo we have examined mice containing two human BAC transgenes with different 5' ends. Mice containing a 255-kilobase (kb) BAC transgene, including 70 kb upstream of the previously defined exon 1, demonstrated a pattern of tissue-specific expression ...

The present  study  was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np)  358 and its association with some reproductive traits in Japanese quail. These traits consisted of weight (WSM) and age at sexual maturity (ASM), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (MEW), and the number of eggs during the 2...
