ALDH inhibition resulted in a spontaneous increase in 4HNE levels in viable cells (21.1 ± 5.8% vs. 42.6 ± 5.2%; P ≤ 0.05) and a corresponding decrease in total motility (41.7 ± 6.2% vs. 6.4 ± 2.6%; P ≤ 0.001) and progressive motility (17.0 ± 4.1% vs. 0.7 ± 0.4%; P ≤ 0.001) of stallion spermatozoa over 24 h. Similarly, inhibition of ALDH in 4HNE-challenged spermatozoa significantly reduced total motility over 4 h (35.4 ± 9.7% vs. 15.3 ± 5.1%, respectively; P ≤ 0.05). This study contributes valuable information about the role of the ALDH enzymes in the maintenance of stallion sperm functionality, with potential diagnostic and in vitro applications for assisted reproductive technologies.]]> Wed 11 Apr 2018 16:45:10 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34663 Wed 10 Apr 2019 13:35:43 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43352 Thu 15 Sep 2022 15:32:31 AEST ]]>
