Abstract
Obesity and diabetes are closely associated with numerous reproductive disorders, including termination of ovulation, irregular menstruation, low fertility, abortion, and risky pregnancy, which are now regarded as global health problems. Paternal/maternal obesity and diabetes can also be transmitted to the subsequent generation via gametes, suggesting the association of epigenetic inheritance with obesity and diabetes, particularly for its effects on offspring. Recent studies indicate that both obesity and diabetes change DNA and histone methylation levels, histone acetylation, and noncoding RNAs such as microRNAs (miRNAs) in oocytes and sperm. Several important genes, such as PPAR-α, Igf2, H19, Fyn, Stella, Sirt3, Sirt6, and Peg3 as well as miRNAs, such as let-7c, reportedly participate in the regulation of epigenetic modifications in mammalian gametes. This review summarizes the recent progress that links obesity/diabetes and reproductive disorders from the perspective of gamete epigenetic modifications.
期刊介绍：
The Journal of Cellular Physiology publishes reports of high biological significance in areas of eukaryotic cell biology and physiology, focusing on those articles that adopt a molecular mechanistic approach to investigate cell structure and function. There is appreciation for the application of cellular, biochemical, molecular and in vivo genetic approaches, as well as the power of genomics, proteomics, bioinformatics and systems biology. In particular, the Journal encourages submission of high-interest papers investigating the genetic and epigenetic regulation of proliferation and phenotype as well as cell fate and lineage commitment by growth factors, cytokines and their cognate receptors and signal transduction pathways that influence the expression, integration and activities of these physiological mediators. Similarly, the Journal encourages submission of manuscripts exploring the regulation of growth and differentiation by cell adhesion molecules in addition to the interplay between these processes and those induced by growth factors and cytokines. Studies on the genes and processes that regulate cell cycle progression and phase transition in eukaryotic cells, and the mechanisms that determine whether cells enter quiescence, proliferate or undergo apoptosis are also welcomed. Submission of papers that address contributions of the extracellular matrix to cellular phenotypes and physiological control as well as regulatory mechanisms governing fertilization, embryogenesis, gametogenesis, cell fate, lineage commitment, differentiation, development and dynamic parameters of cell motility are encouraged. Finally, the investigation of stem cells and changes that differentiate cancer cells from normal cells including studies on the properties and functions of oncogenes and tumor suppressor genes will remain as one of the major interests of the Journal.
