A Comparison of DNA-Methylation during Protoplast Culture of Ponkan Mandarin (Citrus reticulata Blanco) and Tobacco (Nicotiana tabacum L.)

open access: yesPlants
The epigenetic variation in protoplast regeneration is a topic that has attracted interest recently. To elucidate the role of DNA methylation in the regeneration of protoplasts from the ponkan (Citrus reticulata), this study employs the methylation ...

DNA hypermethylation of COL4A1 in ultraviolet-B-induced age-related cataract models in vitro and in vivo [PDF]

open access: yesInternational Journal of Ophthalmology
AIM: To explore the DNA methylation of COL4A1 in ultraviolet-B (UVB)-induced age-related cataract (ARC) models in vitro and in vivo. METHODS: Human lens epithelium B3 (HLEB3) cells and Sprague Dawley rats were exposure to UVB respectively.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Hypermethylation of tumor suppressor genes in cancer

open access: yesSeminars in Cancer Biology, 1999
Hypermethylation of tumor suppressor genes and other genes functionally important in the neoplastic process is a recently recognized process. This epigenetic process is characterized by loss of function of these genes associated with transcriptional loss in the absence of structural alterations.

DNA‐Methylation for Risk‐Stratification of Women Without a Fully Visible Transformation Zone at Colposcopy: A Cross‐Sectional Study

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To evaluate the performance of DNA methylation markers for the detection of cervical precancer among screening‐positive older women without a fully visible transformation zone at colposcopy (TZ3). Design Cross‐sectional study. Setting Colposcopy clinics, Central Denmark Region, 2019–2021.

Integrated Methylome–Transcriptome Analysis Reveals Epigenomic Remodeling and Rho GTPase–Linked Immune–Epithelial Crosstalk in Atopic Dermatitis

open access: yesAllergy, EarlyView.
Integrated methylome–transcriptome–microbiome analysis of AD skin identified thousands of DMRs. Rho GTPase signaling and actin–junctional programs emerged as central hubs integrating immune, epithelial, and microbial interactions in the pathogenesis of atopic dermatitis.

A Rapid and Reliable Test for BRCA1 Promoter Hypermethylation in Paraffin Tissue Using Pyrosequencing

open access: yesDiagnostics
Background: Ovarian cancers harboring inactivating mutations in BRCA1 or BRCA2 demonstrate increased sensitivity to poly (ADP-ribose) polymerase inhibitors (PARPis). BRCA1 promoter methylation could serve as a more precise biomarker for therapy response,

Functional Implications of DNA Methylation in Adipose Biology. [PDF]

open access: yes, 2019
The twin epidemics of obesity and type 2 diabetes (T2D) are a serious health, social, and economic issue. The dysregulation of adipose tissue biology is central to the development of these two metabolic disorders, as adipose tissue plays a pivotal role ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

open access: yesAndrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...
