Mitochondria in oocytes play important roles in many processes, including early embryo
development. Promotion of mitochondrial degradation and biogenesis through Sirtuin 1 …

Hyperthermia during estrus has direct consequences on the maturing oocyte that carries
over to the resultant embryo to compromise its ability to continue in development. Because …

Extreme temperature during summer may lead to heat stress in cattle and compromise their
productivity. It also poses detrimental impacts on the developmental capacity of bovine …

Heat stress (HS) has been known to cause reproductive failure in animals, especially in
summer. HS severely affects the developmental potential of oocytes and leads to low fertility …

The present study assessed the effect of resveratrol on the expression of SIRT1 and
mitochondrial quality and quantity in porcine oocytes. Supplementing the maturation …

The series of events associated with oocyte maturation are susceptible to disruption by
elevated temperature. These events are regulated by a variety of growth factors, such as …

Abstract STUDY QUESTION Does Sirt3 dysfunction result in poor developmental outcomes
for human oocytes after in vitro maturation (IVM)? SUMMARY ANSWER Inefficient Sirt3 …

This study was undertaken to investigate the effects on the nuclear maturation and
subsequent embryonic development of bovine oocytes exposed to heat stress (HS) when …

Stress can affect reproductive performance of lactating cows by targeting the ovarian pool of
follicles and their enclosed oocytes. Among the documented stressors are heat stress (ie …

Heat stress is associated with increased production of reactive oxygen species (ROS) and
disruption of bovine oocyte function. Here, we examined whether the antioxidant melatonin …
