Article Abstract

Cell plasticity is important in development and tissue remodeling. Cells can sense physical and chemical cues from their local microenvironment and transduce the signals into the nucleus to regulate the epigenetic state and gene expression, resulting in a change in cell phenotype. In this review, we highlight the role of mechanical cues in regulating stem cell differentiation and cell reprogramming through the modulation of histone modifications. The effects of various mechanical cues, including matrix stiffness, mechanical stretch, and shear stress, on cell fate during tissue regeneration and remodeling will be discussed. Taken together, recent work demonstrates that the alterations in histone modifications by mechanical stimuli can facilitate epigenetic changes during cell phenotypic switching, which has potential applications in the development of biomaterials and bioreactors for cell engineering.

Study Question: What is the effect of hCG on the epigenetic profile and the expression of other molecular factors in endometrial stromal cells (ESCs)?

Summary Answer: Our findings suggest that hCG treatment alters the molecular environment of decidualized ESCs, potentially influencing implantation and immune regulation through epigenetic modifications and changes in the levels of secreted proteins and micro-ribonucleic acids (miRNAs).

What Is Known Already: Embryo implantation depends not only on the quality of the embryo but also on the receptivity of the endometrium, the specialized lining of the uterus that undergoes dynamic changes to support pregnancy. Effective communication between the maternal and fetal compartments, facilitated by molecular signals and cellular interactions, is essential for successful implantation.

Genome-wide association studies (GWAS) relevant to osteoporosis have identified hundreds of loci; however, understanding how these variants influence the phenotype is complicated because most reside in non-coding DNA sequence that serves as transcriptional enhancers and repressors. To advance knowledge on these regulatory elements in osteoclasts (OCs), we performed Micro-C analysis, which informs on the genome topology of these cells and integrated the results with transcriptome and GWAS data to further define loci linked to BMD. Using blood cells isolated from 4 healthy participants aged 31-61 yr, we cultured OC in vitro and generated a Micro-C chromatin conformation capture dataset.

Epigenetic regulation of bladder cancer in the context of aging.

Bladder cancer (BC) is a disease that predominantly affects older adults, with aging playing a critical role in its onset and progression. Age-associated phenomena, including immunosenescence and chronic inflammation, form a pro-tumor milieu, while genomic instability and epigenetic drift further increase cancer risk. The review highlights the dual role of DNA methylation in BC: global hypomethylation can activate transposable elements and oncogenes, whereas focal hypermethylation silences tumor-suppressor genes like CDKN2A, especially detrimental in older tissues that rely on these genes for senescence control.

Diabetes and viral hepatitis, particularly hepatitis B (HBV) and hepatitis C (HCV), are significant global health burdens with complex interconnections. This review discusses the molecular mechanisms linking viral hepatitis to diabetes, focusing on inflammatory pathways, oxidative stress, and epigenetic modifications. Key findings highlight the role of STAT3 in promoting insulin resistance and β-cell apoptosis, the impact of ER stress and NOX-mediated oxidative stress on metabolic dysfunction, and the influence of epigenetic changes such as DNA methylation and histone acetylation on glucose homeostasis.

Advances in genome engineering have paved the way for targeted epigenome engineering, providing fundamental insights into the role of epigenetic modifications in trait inheritance. Engineered epialleles have already delivered stable, heritable changes in agronomic traits. Despite this capacity, progress in the field has not yet achieved its potential, leaving many avenues of research unexplored.
