Memory remains an obligatory regime of the human brain, and impaired memory causes serious obstacles in our everyday life. Alzheimer's disease (AD) is one such neurodegenerative disease which mostly affects the elderly population, above the age of 60; marked by cognitive impairment of memory. Besides the known targets of AD against the several etiologies known to date, the zone of epigenetics has recently evolved as an ingenious field in AD. Epigenetic modifications do not affect DNA sequence but only long-term gene expression. Considering the complex multifactorial nature of AD, we herein discuss the various epigenetic targets which might give rise to potential therapeutic approaches. We reviewed the possible epigenetic targets for AD-like HDAC, Sirtuins, glial cells, miRNA and epigenetic modifications like DNA methylation. A deeper insight into these target areas can surely evolve AD diagnosis and therapeutics.

RNA N6-methyladenosine (m6A) plays diverse roles in RNA metabolism and its deregulation contributes to tumor initiation and progression. Clear cell renal cell carcinoma (ccRCC) is characterized by near ubiquitous loss of followed by mutations in epigenetic regulators , , and . Mutations in , a histone H3 lysine 36 trimethylase (H3K36me3), are associated with reduced survival, greater metastatic propensity, and metabolic reprogramming.

The secretome is composed of cell surface membrane proteins and extracellular secreted proteins that are synthesized via secretory machinery, accounting for approximately one-third of human protein-encoding genes and playing central roles in cellular communication with the external environment. Secretome protein-protein interactions (SPPIs) mediate cell proliferation, apoptosis, and differentiation, as well as stimulus- or cell-specific responses that regulate a diverse range of biological processes. Aberrant SPPIs are associated with diseases including cancer, immune disorders, and illness caused by infectious pathogens.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver condition, characterized by a spectrum that progresses from simple hepatic steatosis to nonalcoholic steatohepatitis, which may eventually lead to cirrhosis and hepatocellular carcinoma. The precise pathogenic mechanisms underlying NAFLD and its related metabolic disturbances remain elusive. Epigenetic modifications, which entail stable transcriptional changes without altering the DNA sequence, are increasingly recognized as pivotal.

Background: The BCG vaccine induces trained immunity, an epigenetic-mediated increase in innate immune responsiveness. Therefore, this clinical trial evaluated if BCG-induced trained immunity could decrease coronavirus disease 2019 (COVID-19)-related frequency or severity.
Methods: A double-blind, placebo-controlled clinical trial of healthcare workers randomized participants to vaccination with BCG TICE or placebo (saline).

The coexistence of type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) represents a significant global health challenge, contributing to substantial morbidity, mortality, and economic burden. T2DM is the leading cause of CKD, and CKD exacerbates diabetes-related complications, creating a bidirectional relationship driven by oxidative stress, inflammation, and endothelial dysfunction. Diabetic kidney disease (DKD), affecting some individuals with T2DM, accelerates progression to end-stage renal disease (ESRD) and increases cardiovascular mortality.
