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 ]]> Identification and characterisation of a novel splice variant of mouse and rat cytochrome b5/cytochrome b5 reductase https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2266 Sat 24 Mar 2018 08:26:55 AEDT ]]> Prolactin exerts a prosurvival effect on human spermatozoa via mechanisms that involve the stimulation of Akt phosphorylation and suppression of caspase activation and capacitation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11205 Sat 24 Mar 2018 08:12:44 AEDT ]]> Redox regulation of human sperm function: from the physiological control of sperm capacitation to the etiology of infertility and DNA damage in the germ line https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17995 Sat 24 Mar 2018 07:56:35 AEDT ]]> Identification of cytochrome-b5 reductase as the enzyme responsible for NADH-dependent lucigenin chemiluminescence in human spermatozoa https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41 Sat 24 Mar 2018 07:42:12 AEDT ]]> Investigation of the stallion sperm proteome by mass spectrometry https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27065 Sat 24 Mar 2018 07:25:20 AEDT ]]> Evidence that extrapancreatic insulin production is involved in the mediation of sperm survival https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40400 Mon 11 Jul 2022 13:55:46 AEST ]]>
