Polymorphisms of the bovine growth differentiation factor 9 gene associated with superovulation performance in Chinese Holstein cows.

An SduI polymorphism at intron 20 of the Chinese Holstein cow STAT4 gene and its effect on milk performance traits.

The signal transducer and activator of transcription (STAT) genes are responsive to a wide range of cytokines, growth factors, and hormones, and thus control important biological processes. In humans, STAT4 mutations have been identified as genetic markers for rheumatoid arthritis, systemic lupus erythematosus, and primary Sjögren's syndrome, whereas little research has been conducted on bovine...

Study of Placental Lactogen Gene Polymorphism and Its Association With Milk Production Traits in The Holstein Cows

Placental Lactogen is a polypeptide hormone that is produced by the Placenta, also known as chorionic somatomammotropin hormone. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. The objective of this study was to investigate the bovine Placental Lactogen (bPL) gene polymorphism of Holstein cows in Razavi Khorasan province. Blood samples we...

Single Nucleotide Polymorphism in the Promoter Region of Bovine Interleukin 8 Gene and its Association with Milk Production Traits and Somatic Cell Score of Holstein Cattle in Iran

Background: Interleukie-8 is a proinflammatory cytokine and a potent chemotactic and activation factor for neutrophils. It has been reported to be expressed in high levels by various cell types after immune stimulation and mediates neutrophil recruitment in host. Objectives: The aim of this study was to analysis of the relationship between single nucleotide polymorphisms (SNPs) at position -18...

Association of TG-repeats in the 5’-flanking region of bovine growth hormone receptor (GHR) gene with milk production traits and somatic cell count in Holstein cattle

The growth hormone receptor (GHR) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (GH) on target tissues. Therefore, the purpose of this study was to examine the association of TG-repeat polymorphisms in the 5’-flanking region of bovine GHR gene with milk production traits and somatic cell score (SCS) in Holstein cattle of Iran. The part of 5’...
