Oocyte DNA methylation is an important epigenetic process established during oogenesis that contributes to genomic imprinting, maternal epigenetic regulation, fertility, and early embryonic development.

Germline differentially methylated regions establish parent-specific DNA methylation patterns during sperm and oocyte development and help regulate genomic imprinting and early embryonic development.

DNA methylation at imprinting control regions is a key mechanism of genomic imprinting. Learn how methylation is established, maintained, and reprogrammed and how it regulates parent-of-origin gene expression and development.

Germ-cell epigenetic memory refers to persistent epigenetic information associated with sperm or oocytes that may influence gene regulation and development. Explore DNA methylation, histone modifications, non-coding RNA, genomic imprinting, germ-cell reprogramming, environmental influences, and the evidence for inheritance across generations.

Small RNAs such as microRNAs, siRNAs, and piRNAs can regulate gene expression, chromatin, DNA methylation, and genome stability. Explore their potential roles in germ-cell regulation, parental effects, epigenetic inheritance, development, environmental responses, and transgenerational biology.

Non-coding RNAs regulate gene expression, chromatin, development, and cellular processes and may contribute to epigenetic effects across generations. Learn about microRNAs, siRNAs, piRNAs, long non-coding RNAs, germ-cell RNA, environmental influences, and the challenges of demonstrating true transgenerational inheritance.

Histone modifications regulate chromatin structure and gene expression and may contribute to epigenetic effects across generations. Learn about histone acetylation, methylation, germ-cell epigenetics, reprogramming, environmental influences, genomic imprinting, and the challenges of demonstrating true transgenerational inheritance.

DNA methylation is a major epigenetic mechanism that regulates gene expression and may contribute to transgenerational effects under specific biological conditions. Learn about DNA methylation, germ-cell reprogramming, DNA methyltransferases, imprinting, environmental influences, epimutations, and the challenges of demonstrating true transgenerational inheritance.

Intergenerational epigenetic effects describe how parental exposures and physiological conditions may influence gene regulation and biological traits in offspring. Learn about DNA methylation, histone modifications, germ-cell epigenetics, maternal and paternal effects, environmental influences, development, and the distinction from transgenerational inheritance.

Epigenetic reprogramming in germ cells resets and establishes gene-regulatory patterns during the formation of eggs and sperm. Learn about DNA methylation, histone modifications, chromatin remodeling, genomic imprinting, X-chromosome regulation, epigenetic inheritance, and reproductive genetics.

Epigenetic reprogramming resets and establishes gene-regulatory states through changes in DNA methylation, histone modifications, chromatin structure, and other epigenetic mechanisms. Learn about its role in germ cells, embryonic development, stem cells, inheritance, aging, cancer, and human genetics.

Epigenetic inheritance describes the maintenance or transmission of gene-regulatory information without changing the DNA sequence. Learn about DNA methylation, histone modifications, genomic imprinting, X-chromosome inactivation, epigenetic reprogramming, and disease.

Genomic imprinting is an epigenetic process in which gene expression depends on whether an allele is inherited from the mother or father. Learn about its mechanisms, imprinting control regions, DNA methylation, disorders, testing, and role in human genetics.

Histone modifications are epigenetic changes that regulate chromatin structure and gene expression. Learn about histone acetylation, methylation, phosphorylation, ubiquitination, their mechanisms, disease associations, and therapeutic significance.

Epigenetic mutations and changes alter gene regulation without necessarily changing the DNA sequence. Learn about DNA methylation, histone modifications, chromatin remodeling, gene expression, disease, cancer, and epigenetic testing.
