Epigenetic factors alter phenotype without changing genotype. A primary molecular mechanism underlying epigenetics is the alteration of chromatin structure by covalent DNA modifications, covalent histone modifications, and nucleosome reorganization. Remodeling of chromatin structure regulates DNA methylation, replication, recombination, and repair as well as gene expression. As these functions would predict, dysfunction of the proteins that remodel chromatin causes an array of multi-system disorders and neoplasias. Insights from these diseases suggest that during embryonic and fetal life, environmental distortions of chromatin remodeling encode a 'molecular memory' that predispose the individual to diseases in adulthood.

Enhanced environmental stress tolerance is important for microbial production of biofuels and biobased chemicals. However, the roles of chromatin regulation in stress tolerance and bioproduction remain unclear. Here, we explore the effects of Ino80, the core subunit of the INO80 chromatin remodeling complex, on yeast stress adaptation.

Heart disease, particularly resulting from myocardial infarction (MI), continues to be a leading cause of mortality, largely due to the limited regenerative capacity of the human heart. Current therapeutic approaches seek to generate new cardiomyocytes from alternative sources. Direct cardiac reprogramming, which converts fibroblasts into induced cardiomyocytes (iCMs), offers a promising alternative by enabling in situ cardiac regeneration and minimizing tumorigenesis concerns.

The tumor suppressor gene SMARCA4, a critical component of the SWI/SNF chromatin remodeling complex, is frequently inactivated in various cancers, including clear cell renal cell carcinoma (ccRCC). Despite its significance, the role of SMARCA4 in ccRCC development and its potential therapeutic vulnerabilities have not been fully explored. Our research found that SMARCA4 deficiency was associated with poor prognosis and was observed in a subset of high-grade ccRCCs.

Proper chromatin remodeling is crucial for many cellular physiological processes, including the repair of DNA double-strand break (DSB). While the mechanism of DSB repair is well understood, the connection between chromatin remodeling and DSB repair remains incompletely elucidated. In this review, we aim to highlight recent studies demonstrating the close relationship between chromatin remodeling and DSB repair.

Stress is a fundamental adaptive response mediated by the amygdala and Hypothalamus-Pituitary-Adrenal (HPA) axis. Extreme or chronic stress, however, can result in a multitude of neuropsychiatric disorders, including anxiety, paranoia, bipolar disorder (BP), major depressive disorder (MDD), and Post-Traumatic Stress Disorder (PTSD). Despite widespread exposure to trauma (70.
