Key result
Induction of polycystic ovary syndrome significantly reduced the expression of the Sirtuin-3 gene in the ova of NMRI mice compared to healthy controls (ratio 0.18; P<0.05).
Why the study?
Elevated free radicals in ova reduce fertilization quality and are increased in polycystic ovary syndrome, but the expression of the mitochondrial antioxidant gene Sirtuin-3 in affected ova required investigation.
Does polycystic ovary syndrome reduce the expression of the Sirtuin-3 gene in the ova of NMRI mice?
Comparison
Estradiol valerate-induced polycystic ovary syndrome vs control

Sirtuin-3 expression in PCOS mouse ova remains hypothesis-generating; human studies needed before any clinical relevance.
Does polycystic ovary syndrome reduce the expression of the Sirtuin-3 gene in the ova of NMRI mice?
Effect estimate: ratio of 0.18
p-value: p=<0.05
Polycystic ovary syndrome reduces the expression of the Sirtuin-3 gene in the ova of mice, which may contribute to oxidative stress and reduced fertilization quality.
Jalali et al. (2022) studied Polycystic ovary syndrome (n=12). Estradiol valerate (PCOS induction) vs. Healthy control mice was evaluated on Expression of Sirtuin-3 gene in the ova (ratio of 0.18, p=<0.05). Induction of polycystic ovary syndrome significantly reduced the expression of the Sirtuin-3 gene in the ova of NMRI mice compared to healthy controls (ratio 0.18; P<0.05).
