Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is known as the most common endocrine and metabolic disorder in the reproductive-age women. Due to the effects of PCOS on the physical and mental health, the investigation of the factors affecting the development of PCOS is crucial. Hexose-6-phosphate dehydrogenase (H6PD) is a microsomal enzyme that catalyzes the first two reactions of the oxidative chain of the pentose phosphate pathway. The present study examined the polymorphisms of the H6PD gene (R453Q and D151A) in PCOS patients of Iranian Kurdish women.<br />Materials and Methods: In this case-control study, a total, of 200 female volunteers in two equal groups participated in our study. The PCOS patients were selected based on the Rotterdam diagnostic criteria. The association of H6PD gene polymorphisms, D151A and R453Q, with the development of PCOS were investigated. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping. Statistical analysis was applied by the SPSS (version 16) software.<br />Results: Statistically significant lower frequencies of AA+AG genotype (37% vs. 55%, P=0.01) and A allele (22.5%<br />vs. 34%, P=0.01) of R453Q were observed in the patients compared to the controls. In the case of D151A, no significant<br />differences were observed in the frequency of genotypes and alleles between the two groups. CONCLUSION The findings of this study suggest that variants of H6PD R453Q affect the risk of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting approximately 5-20% of women of reproductive age. PCOS is a multifactorial, complex, and heterogeneous disease, characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries, which may lead to impaired fertility. Besides the reproductive outcomes, multiple comorbidities, such as metabolic disturbances, insulin resistance, obesity, diabetes, and cardiovascular disease, are associated with PCOS. In addition to the clear genetic basis, epigenetic alterations may also play a central role in PCOS outcomes, as environmental and hormonal alterations directly affect clinical manifestations and PCOS development. Here, we highlighted the epigenetic modifications in the multiplicity of clinical manifestations, as well as environmental epigenetic disruptors, as intrauterine hormonal and metabolic alterations affecting embryo development and the adulthood lifestyle, which may contribute to PCOS development. Additionally, we also discussed the new approaches for future studies and potential epigenetic biomarkers for the treatment of associated comorbidities and improvement in quality of life of women with PCOS.

Conditional MitoTimer reporter mice for assessment of mitochondrial structure, oxidative stress, and mitophagy. Mitochondrion 2017; 44:20-26. [PMID: 29274400 PMCID: PMC6387589 DOI: 10.1016/j.mito.2017.12.008] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Revised: 10/24/2017] [Accepted: 12/15/2017] [Indexed: 11/18/2022]
Abstract
Assessment of structural and functional changes of mitochondria is vital for biomedical research as mitochondria are the power plants essential for biological processes and tissue/organ functions. Others and we have developed a novel reporter gene, pMitoTimer, which codes for a redox sensitive mitochondrial targeted protein that switches from green fluorescence protein (GFP) to red fluorescent protein (DsRed) when oxidized. It has been shown in transfected cells, transgenic C. elegans and Drosophila m., as well as somatically transfected adult skeletal muscle that this reporter gene allows quantifiable assessment of mitochondrial structure, oxidative stress, and lysosomal targeting of mitochondria-containing autophagosomes. Here, we generated CAG-CAT-MitoTimer transgenic mice using a transgene containing MitoTimer downstream of LoxP-flanked bacterial chloramphenicol acetyltransferase (CAT) gene with stop codon under the control of the cytomegalovirus (CMV) enhancer fused to the chicken β-actin promoter (CAG). When CAG-CAT-MitoTimer mice were crossbred with various tissue-specific (muscle, adipose tissue, kidney, and pancreatic tumor) or global Cre transgenic mice, the double transgenic offspring showed MitoTimer expression in tissue-specific or global manner. Lastly, we show that hindlimb ischemia-reperfusion caused early, transient increases of mitochondrial oxidative stress, mitochondrial fragmentation and lysosomal targeting of autophagosomes containing mitochondria as well as a later reduction of mitochondrial content in skeletal muscle along with mitochondrial oxidative stress in sciatic nerve. Thus, we have generated conditional MitoTimer mice and provided proof of principle evidence of their utility to simultaneously assess mitochondrial structure, oxidative stress, and mitophagy in vivo in a tissue-specific, controllable fashion.
