identification of associated genes with energy balance, yield and feed intake are recent interests of the animal breeding researchers. najdi breed is the famous cattle breed in the khuzestan province. in this research for the investigation of leptin gene promoter ,from 15 najdi cows in the shushtar cattle center station was taken. dna from whole blood was extracted and 544bp and 566 bp two piec...
introduction: leptin is a hormone resulting from the obesity gene which could be important in the pathogenesis of the insulin. only limited data concerning the interaction of insulin, glucose tolerance and free leptin are available and no data exist on the potential influence of free vs. bound circulating leptin. we, therefore, studied percentage of free to total leptin in diabetic patients. ma...

In dairy cattle, the increase in milk yield has been accompanied by a more negative energy balance during early lactation and a decrease in fertility. The 167 amino acid protein product of the ob gene was named leptin (derived from the Greek term ‘leptos’ meaning thin). The leptin hormone, as a 16-kDa protein is synthesized mainly by adipose tissue and is involved in regulation of food intake, ...

A candidate gene suspected of affecting pigs' reproductive traits is known as the leptin (LEP) gene. Based on information found in Leptin GenBank's DNA sequence database, this research aimed to determine single nucleotide polymorphisms (SNPs) and changes nucleotides phylogenetic trees pigs. The data from NCBI GenBank was used obtain three different sequences for were aligned using BioEdit estab...
OBJECTIVE Adipose tissue displays depot-specific metabolic properties and a predominant gene expression of leptin in subcutaneous tissue. The aim of the study was to evaluate leptin mRNA expression in various adipose tissues and to relate it to plasma leptin concentrations. Furthermore, developmental changes in leptin gene expression from childhood to adulthood were examined. DESIGN AND METHO...
To determine if the age-dependent increase of adiposity is directly related to altered obese (ob) and fatty acid synthase (FAS) gene expression, we assessed an adiposity index, leptin and FAS mRNA levels, FAS activity in perirenal adipose tissue and serum leptin concentration in rats aged 1, 2, 3, 6 and 20 months. The results indicate that there are two distinct phases of changes in perirenal w...
Background: Introduction of leptin, a product of the obese gene, recently has led to numerous experiments to better understand body weight and composition function. Based on these findings, leptin is proposed to be an important factor in energy balance and metabolism to influence body weight. In addition, investigators have reported contradictory findings about the influence of physical ex...
Recent studies have shown that polymorphisms in leptin and leptin receptor genes are associated with increased risk for breast cancer. This study aimed at investigating -2548 G/A polymorphism in leptin gene and Q223R polymorphism in leptin receptor gene in patients with breast cancer. The study included 45 women with breast cancer and 41 healthy women. PCR-RFLP was used to determine the genotyp...
