Epigenetics of reproductive infertility.
Infertility is a complex pathophysiological condition. It may caused by specific or multiple physical and physiological factors, including abnormalities in homeostasis, hormonal imbalances and genetic alterations. In recent times various studies implicated that, aberrant epigenetic mechanisms are associated with reproductive infertility. There might be transgenerational effects associated with ...
متن کاملEpigenetics and assisted reproductive technology.
During gametogenesis, the female and male germ cells undergo a process whereby imprinting marks are erased from the genome. During the later stages of germ-cell development, the methylation marks of the female and male germ lines are re-established. A second phase of demethylation of the genome occurs at the time of fertilization, and during development of the early embryo. Assisted reproductiv...
متن کاملEpigenetics: A key paradigm in reproductive health
It is well established that there is a heritable element of susceptibility to chronic human ailments, yet there is compelling evidence that some components of such heritability are transmitted through non-genetic factors. Due to the complexity of reproductive processes, identifying the inheritance patterns of these factors is not easy. But little doubt exists that besides the genomic backbone, ...
متن کاملEpigenetics
By the time the reader reaches Chapter 20, which focuses specifically on cancer, the mechanisms and symptoms of cancer are relatively easy to understand. Chapter 20 covers topics such as the cellular phenotypes of cancer, genes linked to cancer, and cancer treatment. While the primary literature citations at the end of the chapter will provide good starting points for the curious student, a mor...
متن کاملEpigenetics
In this issue we focus on the topic of Epigenetics, the study of heritable phenotypic traits not encoded by the genetic sequence. While every cell in your body has a copy of your genetic code in the form of DNA, many of the unique features between different cell types and between different individuals arise from unique patterns of gene expression. In recent decades, it has become increasingly c...
