The Langmuir isothermal model and the Langmuir–Freundlich isothermal model suggest that ACV-MIMs have more homogeneous binding sites than MIPs prepared through normal imprinting.
Our data suggest that a specific epigenetic substrate, defined by a normal imprinting status and monoallelic expression of IGF2 are required for a strong effect of SYT-SSX on IGF2 expression and that changes in the baseline epigenetic status, can prevent SYT-SSX1 from exerting its effect on the H19 ICR.
Mice inheriting a maternal copy of a flox-rep-enh allele had both the maternal and the paternal tandem DNA repeats, but underwent an inversion of the normal imprinting pattern, with the maternal allele becoming activated and the paternal allele becoming silenced.
A normal imprinting pattern, maintenance of imprint (MOI), was most frequent in NDN (93.5%, 29/31).
Variants that disrupt normal imprinting may also influence the nature of observed associations.
Theoretically, after zygotic gene activation ZFP57 could engage newly synthesized TRIM28 expressed from the paternal allele to attract the whole modifier complex and recover normal imprinting.
The normal imprinting marks are inherited from the parental gametes and are then maintained in the somatic cells of an individual.
Nine of the breast cancer cases were informative for the Apa1 polymorphism and showed normal imprinting, despite two of these cases having hypomethylation at IGF2.
The inverted orientation of the 1.2 Mb duplication would be compatible with normal imprinting because the KCNQ1 promoter is included in this chromosomal imbalance.
Because the contexts differ from the normal imprinting case, and because nothing is currently known about imprinting in social insects, these predictions can serve as a strong a priori test of the kinship theory of imprinting.
