Effect of superoxide dismutase, catalase, and glutathione peroxidase supplementation in the extender on chilled semen of fertile and hypofertile dogs

Abstract: This study investigated the correlation between oxidative stress status and key canine sperm parameters and the effect of addition of a superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) combination in egg yolk tris-citrate glucose (EYT-G) extender on semen during 10 days of storage at 4℃. Ten Boxer dogs were divided into two groups, fertile (F) and hypofertile (H), depending on pregnancy and live birth rate status in the previous year. Semen evaluation was performed on the day of col… Show more

“…However both increased and decreased OXPHOS activity is detected in TNBC cells, for example it is remarkably elevated in TNBC with RB1 deficiency (163). A fine balance of the development of reactive oxygen species (ROS) and the ability of production and of an antioxidant system to scavenge ROS are essential for normal cellular functions (164). Moderate levels of ROS and reactive nitrogen species (RNS) can serve as signals for promoting cell proliferation and survival, while severe increases of ROS/RNS can cause cell death (165).…”

“…Antioxidants are represented by two groups of compounds: enzymatic antioxidants, which include superoxide dismutase, catalase and glutathione peroxidase, and non‐enzymatic antioxidants, for example vitamin E, vitamin A, vitamin C and uric acid (Del Prete et al, ). Substances with the antioxidative properties, which are a part of dog semen composition, are localized mainly in a small cytoplasmic area in the sperm midpiece and in the prostatic fluid (Luberda, ).…”

“…GUERRA, 2010). JÚNIOR et al, 1998;PRETE et al, 2018;MORAIS;TONIOLLI, 2018) O controle da concentração de radicais livres do sêmen é realizado pelos antioxidantes endógenos, do plasma seminal e do espermatozoide, que são capazes de neutralizar as EROs (LECEWICZ et al, 2018b;, evitando a sobrecarga e preservando a qualidade do sêmen (LONE et al, 2018;PRETE et al, 2018). Certos antioxidantes podem ser eficazes após o descongelamento, por reduzir o impacto do estresse oxidativo nessa fase .…”

“…As EROs são prejudiciais ao organismo quando ocorre aumento exacerbado em sua produção ou quando há diminuição de agentes antioxidantes (ANDRADE et al, 2010;DOWLING;SIMMONS, 2009;GATÉ et al, 1999;GUTTERIDGE, 1999;PRETE et al, 2018). Elas causam danos aos lipídios, proteínas, carboidratos e ao material genético; levando a perdas irreversíveis da cinética do espermatozoide, redução da fusão espermatozoide/oócito, alteração do citoesqueleto e danos ao DNA PRETE et al, 2018). O choque frio e os danos causado pela congelação estão associados ao excesso das EROs e à geração do estresse oxidativo.…”
