Aquaporins in bovine male reproductive tract: From calves to reproductive bulls.

The role of aquaporins (AQPs) in the male reproductive system of cattle, particularly in relation to spermatogenesis, remains incompletely understood. Therefore, the aim of this study was to analyze the developmental changes in AQP8 and AQP11 expression in the bovine (Bos taurus) male reproductive tract. Tissue samples were collected from three age groups of animals: calves aged 5-6 weeks (n = 10), young bulls aged 15-25 weeks (n = 10) and reproductive bulls aged 2-6 years (n = 11).

A Step Forward in Understanding the Expression of Classical Aquaporins in the Male Reproductive Tract: Study Findings in Cattle ().

Aquaporins (AQPs), also known as water channels, appear to be particularly promising in maintaining male reproductive potential. Therefore, this study aimed to determine the presence of classical AQPs in the bovine () reproductive system and analyze changes in their expression with age using immunohistochemistry and Western blotting. Of the six classical AQPs, AQP0, AQP1, AQP4, AQP5 and AQP6 were detected, while AQP2 was absent.

Cellular Distribution of Aquaporin 3, 7 and 9 in the Male Reproductive System: A Lesson from Bovine Study ().

The increasing incidence of male infertility in humans and animals creates the need to search for new factors that significantly affect the course of reproductive processes. Therefore, the aim of this study was to determine the temporospatial expression of aquaglyceroporins (AQP3, AQP7 and AQP9) in the bovine () reproductive system using immunohistochemistry and Western blotting. The study also included morphological analysis and identification of GATA-4.

Gene and Protein Accumulation Changes Evoked in Porcine Aorta in Response to Feeding with Two Various Fructan Sources.

In this study, two different ITFs sources were incorporated into a cereal-based diet to evaluate possible aortic protein and gene changes in nursery pigs. The animals were fed two different experimental diets from the 10th day of life, supplemented with either 4% of dried chicory root (CR) or with 2% of native inulin (IN). After a 40-day dietary intervention trial, pigs were sacrificed at day 50 and the aortas were harvested.
