Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Video Imprint [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
A new unified video analytics framework (ER3) is proposed for complex event retrieval, recognition and recounting, based on the proposed video imprint representation, which exploits temporal correlations among image features across video frames. With the video imprint representation, it is convenient to reverse map back to both temporal and spatial ...

Imprinting and its disorders in evolutionary perspective

open access: yesActa 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 ...

More Than Just a Barrier: The Immune Functions of the Airway Epithelium in Asthma Pathogenesis

open access: yesFrontiers in Immunology, 2020
Allergic bronchial asthma is a chronic disease of the airways that is characterized by symptoms like respiratory distress, chest tightness, wheezing, productive cough, and acute episodes of broncho-obstruction. This symptom-complex arises on the basis of

Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]

open access: yes, 2015
Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (

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

open access: yesNature 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

open access: yesBMC 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 ...

Neurophysiological Mechanisms of Cow–Calf Bonding in Buffalo and Other Farm Animals

open access: yesAnimals, 2021
In buffaloes and other mammalian farm species, the mother provides food and protection to the young, but she is also the main source of behavioral and social learning for the offspring.

Effect of Methane Inhibitors on Ruminal Microbiota During Early Life and Its Relationship With Ruminal Metabolism and Growth in Calves

open access: yesFrontiers in Microbiology, 2021
The present study aimed to determine whether dietary supplementation with methanogen inhibitors during early life may lead to an imprint on the rumen microbial community and change the rumen function and performance of calves to 49-weeks of rearing ...

Imprinted Anti-Hemagglutinin and Anti-Neuraminidase Antibody Responses after Childhood Infections of A(H1N1) and A(H1N1)pdm09 Influenza Viruses

open access: yesmBio, 2023
Immune imprinting is a driver known to shape the anti-hemagglutinin (HA) antibody landscape of individuals born within the same birth cohort. With the HA and neuraminidase (NA) proteins evolving at different rates under immune selection pressures, anti ...
