Inversion of the imprinting control region of the Peg3 domain
The imprinting of the mouse Peg3 domain is controlled through a 4-kb genomic region encompassing the bidirectional promoter and 1st exons of Peg3 and Usp29. In the current study, this ICR was inverted to test its orientation dependency for the transcriptional and imprinting control of the Peg3 domain. The inversion resulted in the exchange of promoters and 1st exons between Peg3 and Usp29. Pate...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولPEG3 control on the mammalian MSL complex
Peg3 (paternally expressed gene 3) encodes a DNA-binding protein that functions as a transcriptional repressor. Recent studies revealed that PEG3 binds to Msl1 (male-specific lethal 1) and Msl3, the two main components of the MSL complex. In the current study, we investigated potential roles of Peg3 in controlling its downstream genes through H4K16ac, the histone modification by the MSL complex...
متن کاملImprinting of PEG3, the human homologue of a mouse gene involved in nurturing behavior.
The paternally expressed Peg3 gene in mice encodes an unusual Krüppel-type zinc finger protein implicated in critical cellular and behavioral functions including growth, apoptosis, and maternal nurturing behavior. Methylation and expression analyses were used to determine whether PEG3 on chromosome 19q13.4 is imprinted in humans. The PEG3 promoter is encompassed within a large CpG-rich region t...
متن کاملParental and sexual conflicts over the Peg3 imprinted domain
In the current study, the imprinting control region of the mouse Peg3 domain was deleted to test its functional impact on animal growth and survival. The paternal transmission of the deletion resulted in complete abolition of the transcription of two paternally expressed genes, Peg3 and Usp29, causing the reduced body weight of the pups. In contrast, the maternal transmission resulted in the un...
