Paternal imprinting
WebDec 5, 2024 · Taken together, TSa2i/L AG-haESCs preserve the epigenetic integrity of paternal imprints, including hypermethylated DNA methylation, deposition of H3K9me3 marks, and ZFP57 bindings. Deposition of H3K4me3 prevents de novo methylation of DMRs in 2i/L-SF/a2i/L-switched AG-haESCs WebHaig's kinship theory of genomic imprinting argues that PSGE arises when kinship asymmetries between interacting kin create conflicts between maternally and paternally derived alleles. Greater maternal than paternal relatedness within groups selects for more "abstemious" expression of maternally derived alleles and more "greedy" expression of ...
