چکیده

The surface expression of CD9 (cluster-of-differentiation antigen-9) in sperms of certain mammalian species has been attributed to its fusion with the egg and thereby dictating the fertility of species. In the present study, we investigated the association of CD9 with crossbred bull sperm quality and quantity trait was analyzed using a total of 96 Frieswal (HF × Sahiwal) crossbred. A single nucleotide polymorphism (g.358A > T) in intron 6 was significantly associated with sperm concentration (P < 0.05) and motility percentage (P < 0.01). mRNA was extracted from good (progressive motility > 50%) and motility impaired (progressive motility < 50%) bull semen. The mRNA expression and seminal plasma protein concentration of CD9 was significantly (P < 0.05) higher among good quality bull semen than motility impaired ones. Our results thus may indicate that, mutation in the intronic region may be responsible for the instability of RNA and the subsequent functional protein expression.

The g.-165 T>C Rather than Methylation Is Associated with Semen Motility in Chinese Holstein Bulls by Regulating the Transcriptional Activity of the HIBADH Gene

The 3-hydroxyisobutyrate dehydrogenase (HIBADH) is regarded as a human sperm-motility marker. However, the molecular mechanisms involved in the regulation of expression of the HIBADH gene in bulls remain largely unknown. HIBADH was detected in the testis, epididymis, and sperm via reverse transcription polymerase chain reaction and Western blot analysis. It is also expressed in the seminiferous...

AIM To compare the seminal attributes of neat, pre-freeze (at equilibration), and post-freeze (24 h after freezing) semen in pure and crossbred Jersey bulls. MATERIALS AND METHODS Total 36 ejaculates (3 ejaculates from each bull) were collected from 6 pure Jersey and 6 crossbred Jersey bulls and evaluated for various seminal attributes during neat, pre-freeze, and post-freeze semen. RESULTS...

Single nucleotide polymorphism of FGF2 gene in Iranian Holstein proven bulls

Fibroblast growth factor 2 (FGF2) serves in the uterine endometrium during estrous presenting in the bovine mammary gland which is responsible to express interferon-T (IFNT), and is an important agent to encourage the continuation of pregnancy in the ruminants. Significant associations have been found between genes affected by IFNT and genes that are responsible for milk production traits. Seme...
