Today, the use of oak as a replacement feed in poultry diets is well documented. However, oak contains polyphenol compounds (tannins) as antinutrient factors resulted in limited usage in the poultry rations. Generally, consumption of feeds containing tannin could affect gene expression level of immune system. Therefore, the aim of this study was to investigate the effect of different levels of ...
GDF9 gene is one of the most important effective factors on litter size in sheep. Thus, the aim of the present study was to detect single nucleotide polymorphisms (SNPs) available in exon 2 of GDF9 gene in pure and crossbred of Pakistani sheep using PCR-SSCP. Hence, blood samples were collected from 30 Pakistani sheep, 17 crossbred sheep (Pakistani rams × Lori-Bakhtiari) and 7 crossbred sheep (...
Genetic improvement programs may improve disease resistance in animal production. The best-characterized genetic control of disease resistance and immune response in animals is the one associated with the Major Histocompatibility Complex (MHC). The ovine lymphocyte antigenof DRB1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...
Mastitis is one of the most prevalent and costly diseases affecting dairy cattle production. In the present study, effects of tumor necrosis factor (alpha isomer) gene (TNF-α) polymorphisms on milk somatic cell count (SCS) and subclinical mastitis was investigated in 121 Holstein dairy cattle. The polymorphisms of a 303 bp fragment of TNF-α gene were investigated by PBR and PCR-SSCP techniques....
Introduction: Today, obesity is one of the main public health problems worldwide due to the increased risk of cancer in obese people and the role of apoptosis in preventing diseases such as cancer. Therefore, the aim of this study was to investigate the effect of cannabis on the expression of Bax and Bcl-2 apoptotic genes in adipose tissue cells. Methods: In this experimental study, 32 adult ma...
