Molecular epigenetics in the management of ovarian cancer: Are we investigating a rational clinical promise?

open access: yesFrontiers in Oncology, 2014
Epigenetics is essentially a phenotypical change in gene expression without any alteration of the DNA sequence; the emergence of epigenetics in cancer research and mainstream oncology is fueling new hope.

Epigenetics and aging

open access: yesScience Advances, 2016
Researchers review how random changes and our environment (for example, diet) determines our life span. Over the past decade, a growing number of studies have revealed that progressive changes to epigenetic information accompany aging in both dividing ...

The preconception environment and sperm epigenetics

open access: yesAndrology, 2020
Infertility is a common reproductive disorder, with male factor infertility accounting for approximately half of all cases. Taking a paternal perceptive, recent research has shown that sperm epigenetics, such as changes in DNA methylation, histone ...

Epi-drugs in combination with immunotherapy: a new avenue to improve anticancer efficacy [PDF]

open access: yes, 2017
Immune checkpoint factors, such as programmed cell death protein-1/2 (PD-1, PD-2) or cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) receptors, are targets for monoclonal antibodies (MAbs) developed for cancer immunotherapy.

Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

open access: yesFEBS Letters, EarlyView.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

A DNMT3A PWWP mutation leads to methylation of bivalent chromatin and growth retardation in mice

open access: yesNature Communications, 2019
PWWP domains of DNMT3A and DNMT3B are proposed to interact with H3K36me3. Here the authors present a mouse model carrying a D329A point mutation in the DNMT3A PWWP domain and find this causes dominant postnatal growth retardation, with aberrant ...

Additional sex combs interacts with enhancer of zeste and trithorax and modulates levels of trimethylation on histone H3K4 and H3K27 during transcription of hsp70. [PDF]

open access: yes, 2017
BACKGROUND: Maintenance of cell fate determination requires the Polycomb group for repression; the trithorax group for gene activation; and the enhancer of trithorax and Polycomb (ETP) group for both repression and activation.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

The Impact of Nutrition and Environmental Epigenetics on Human Health and Disease

open access: yesInternational Journal of Molecular Sciences, 2018
Environmental epigenetics describes how environmental factors affect cellular epigenetics and, hence, human health. Epigenetic marks alter the spatial conformation of chromatin to regulate gene expression.

The Emerging Role of Ten-Eleven Translocation 1 in Epigenetic Responses to Environmental Exposures. [PDF]

open access: yes, 2020
Mounting evidence from epidemiological studies and animal models has linked exposures to environmental factors to changes in epigenetic markers, especially in DNA methylation.
