Temporal hampering of thyroid hormone synthesis just before hatching impeded the filial imprinting in domestic chicks

Frontiers in Physiology, 2023
Thyroid hormones play a critical role in the initiation of the sensitive period of filial imprinting. The amount of thyroid hormones in the brains of chicks increases intrinsically during the late embryonic stages and peaks immediately before hatching ...

Dental pulp stem cells as a promising model to study imprinting diseases

International Journal of Oral Science, 2022
Parental imprinting is an epigenetic process leading to monoallelic expression of certain genes depending on their parental origin. Imprinting diseases are characterized by growth and metabolic issues starting from birth to adulthood. They are mainly due

A Facile Surface-Imprinting Strategy for Trypsin-Imprinted Polymeric Chemosensors Using Two-Step Spin-Coating

Chemosensors, 2023
Surface imprinting used for protein recognition in functional cavities is highly effective in imprinting biomacromolecules to avoid template encapsulation during the formation of a molecularly imprinted polymer (MIP) matrix. Herein, we introduce a facile

Case report: Complete paternal isodisomy on chromosome 18 induces methylation changes in PARD6G-AS1 promotor in a case with arthrogryposis

Frontiers in Genetics, 2023
Uniparental disomy (UPD) is the inheritance of both alleles of a chromosome from only one parent. So far, the detection of UPDs in sequencing data is not well established and a known gap in next-generation sequencing (NGS) diagnostics.

Micro-Nano Machining TiO₂ Patterns without Residual Layer by Unconventional Imprinting

Applied Sciences, 2021
Usually, the residual layer remains after patterning TiO2 sol. The existence of the TiO2 residual layer in the non-pattern region affects its application in microelectronic devices.

Differences in expression rather than methylation at placenta-specific imprinted loci is associated with intrauterine growth restriction

Clinical Epigenetics, 2019
Background Genome-wide studies have begun to link subtle variations in both allelic DNA methylation and parent-of-origin genetic effects with early development.

Imprinting and its disorders in evolutionary perspective

Acta Medica Lituanica, 2014
Bacground. Genomic imprinting is one of the best-studied epigenetic phenomena involving all the main epigenetic processes. Recent investigations led to a huge expansion of knowledge in this field and changed some established paradigms regarding ...

Copy number rather than epigenetic alterations are the major dictator of imprinted methylation in tumors

Nature Communications, 2017
Altered genomic imprinting is frequently reported in cancer. Here, the authors analyze copy number and methylation in cancer cell lines and primary tumors to show that imprinted methylation profiles represent the accumulation of copy number alteration ...

A case of intraplacental gestational choriocarcinoma; characterised by the methylation pattern of the early placenta and an absence of driver mutations

BMC Cancer, 2019
Background Gestational choriocarcinoma is a rare malignancy believed to arise from the trophoblast cells of the placenta. Despite the frequently aggressive clinical nature, choriocarcinoma has been routinely curable with cytotoxic chemotherapy for over ...

Sex dependent imprinting effects on complex traits in mice

BMC Evolutionary Biology, 2008
Background Genomic imprinting is an epigenetic source of variation in quantitative traits that results from monoallelic gene expression, where commonly either only the paternally- or the maternally-derived allele is expressed.
