Aging is one of the most complex and irreversible health conditions characterized by continuous decline in physical/mental activities that eventually poses an increased risk of several diseases and ultimately death. These conditions cannot be ignored by anyone but there are evidences that suggest that exercise, healthy diet and good routines may delay the Aging process significantly. Several studies have demonstrated that Epigenetics plays a key role in Aging and Aging-associated diseases through methylation of DNA, histone modification and non-coding RNA (ncRNA). Comprehension and relevant alterations in these epigenetic modifications can lead to new therapeutic avenues of age-delaying contrivances. These processes affect gene transcription, DNA replication and DNA repair, comprehending epigenetics as a key factor in understanding Aging and developing new avenues for delaying Aging, clinical advancements in ameliorating aging-related diseases and rejuvenating health. In the present article, we have described and advocated the epigenetic role in Aging and associated diseases.

Myocardial ischemia/reperfusion injury (MIRI) worsens ischemic damage, with ferroptosis as a key mediator of this iron-dependent cell death. Lactylation, a novel epigenetic modification, remains poorly understood in MIRI-associated ferroptosis. This study aimed to elucidate the mechanistic link between lactylation and ferroptosis in MIRI.

Introduction: Small nucleolar RNA (snoRNA) mediates RNA modifications, including 2'-O-methylation (Nm) and pseudouridine (Ψ), which has been proven to impact tumor progression. However, the role of snoRNA in the epigenetics of tumors remains poorly understood due to the lack of sufficiently effective experimental methods to identify snoRNA targets. Here, we identified SNORD13H, a C/D box snoRNA, as being downregulated in hepatocellular carcinoma (HCC), and its low expression was associated with HCC development.

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.

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.
