Methylation of BRCA1 and MGMT genes in white blood cells are transmitted from mothers to daughters

open access: yesClinical Epigenetics, 2018
Background Constitutive methylation of tumor suppressor genes are associated with increased cancer risk. However, to date, the question of epimutational transmission of these genes remains unresolved.

ZMIZ2 promotes the development of triple-receptor negative breast cancer

open access: yesCancer Cell International, 2022
Background Triple-receptor negative breast cancer (TNBC) is an aggressive breast tumor subtype that generally has a poor prognosis. This study aimed to investigate the role and regulatory mechanisms of Zinc finger MIZ-type containing 2 (ZMIZ2) in ...

Maternal nutritional status, C1 metabolism and offspring DNA methylation: a review of current evidence in human subjects. [PDF]

open access: yes, 2011
: Evidence is growing for the long-term effects of environmental factors during early-life on later disease susceptibility. It is believed that epigenetic mechanisms (changes in gene function not mediated by DNA sequence alteration), particularly DNA ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Cancer Epigenetics

open access: yesCA: A Cancer Journal for Clinicians, 2010
Epigenetics refers to stable alterations in gene expression with no underlying modifications in the genetic sequence and is best exemplified by differentiation, in which multiple cell types diverge physiologically despite a common genetic code. Interest in this area of science has grown over the past decades, especially since it was found to play a ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Epigenetic control [PDF]

open access: yesJournal of Cellular Physiology, 2009
AbstractEpigenetics refers to mitotically and/or meiotically heritable variations in gene expression that are not caused by changes in DNA sequence. Epigenetic mechanisms regulate all biological processes from conception to death, including genome reprogramming during early embryogenesis and gametogenesis, cell differentiation and maintenance of a ...

MARTRE family proteins negatively regulate CCR4-NOT activity to protect poly(A) tail length and promote translation of maternal mRNA

open access: yesNature Communications
The mammalian early embryo development requires translation of maternal mRNA inherited from the oocyte. While poly(A) tail length influences mRNA translation efficiency during the oocyte-to-embryo transition (OET), molecular mechanisms regulating ...

Control of directionality of chromatin folding for the inter- and intra-domain contacts at the Tfap2c–Bmp7 locus

open access: yesEpigenetics & Chromatin, 2018
Background Contact domains of chromatin serve as a fundamental unit to regulate action of enhancers for target genes. Looping between a pair of CCCTC-binding factor (CTCF)-binding sites in convergent orientations underlies the formation of contact ...

The Unicellular State as a Point Source in a Quantum Biological System. [PDF]

open access: yes, 2016
A point source is the central and most important point or place for any group of cohering phenomena. Evolutionary development presumes that biological processes are sequentially linked, but neither directed from, nor centralized within, any specific ...
