Epigenetic heritability
Epigenetic changes can occur in response to environmental exposure – for example, maternal dietary supplementation with genistein (250 mg/kg) have epigenetic changes affecting expression of the agouti gene, which affects their fur color, weight, and propensity to develop cancer. See more In biology, epigenetics is the study of stable changes in cell function (known as marks) that do not involve alterations in the DNA sequence. The Greek prefix epi- (ἐπι- "over, outside of, around") in epigenetics implies … See more Epigenetic changes modify the activation of certain genes, but not the genetic code sequence of DNA. The microstructure (not code) of DNA itself or the associated chromatin proteins may be modified, causing activation or silencing. This mechanism … See more In the brain Memory Memory formation and maintenance are due to epigenetic alterations that cause the required dynamic changes in gene transcription that create and renew memory in neurons.

This work provides a framework anchoring transcriptional cancer cell states in their epigenetic encoding, inheritance and transition dynamics. © 2024. WebNov 16, 2024 · Epigenetic marks enable cells with the same genetic code to express a broad array of phenotypes by dictating chromatin structure, which modulates transcription and gene expression. During chromatin replication, the epigenetic sequence is temporarily disrupted as marks are randomly distributed between daughter strands.
