Imprinting gene expression
Witryna1 lip 2010 · The imprinted expression of genes may be transient and highly tissue-specific, and there are potentially hundreds of other, as yet undiscovered, imprinted transcripts. The placenta is notable amongst mammalian organs for its high and prolific expression of imprinted genes. Witryna31 maj 2024 · Imprinted gene expression is regulated epigenetically, with DNA methylation and the PRC2 histone mark H3K27me3 playing important roles in regulating differential allelic expression 25, 26,...
