Histone-modifying enzymes play a critical role in chromatin remodeling and are essential for influencing several genome processes such as gene expression and DNA repair, replication, and recombination. The discovery of lysine-specific demethylase 1 (LSD1), the first identified histone demethylase, dramatically revolutionized research in the field of epigenetics. LSD1 plays a pivotal role in a wide range of biological operations, including development, cellular differentiation, embryonic pluripotency, and disease (for example, cancer). This mini-review focuses on the role of LSD1 in chromatin regulatory complexes, its involvement in epigenetic changes throughout development, and its importance in physiological and pathological processes.

Epstein-Barr virus (EBV) contributes to ~1.5% of human cancers, including lymphomas, gastric and nasopharyngeal carcinomas. In most of these, nearly 80 viral lytic genes are silenced by incompletely understood epigenetic mechanisms, precluding use of antiviral agents such as ganciclovir to treat the 200,000 EBV-associated cancers/year.

Background: Chimeric antigen receptor T (CAR-T) cell therapy is more effective in relapsed or refractory diffuse large B cell lymphoma (DLBCL) than other therapies, but a high proportion of patients relapse after CAR-T cell therapy owing to antigen escape, limited persistence of CAR-T cells, and immunosuppression in the tumor microenvironment. CAR-T cell exhaustion is a major cause of relapse. Epigenetic modifications can regulate T cell activation, maturation and depletion; they can be applied to reduce T cell depletion, improve infiltration, and promote memory phenotype formation to reduce relapse after CAR-T cell therapy.

Traumatic brain injury (TBI) constitutes a significant burden on global healthcare systems, especially affecting younger populations, where it is a leading cause of disability and mortality. Current treatments for TBI mainly focus on preventing further brain damage and controlling symptoms. However, despite these approaches, several clinical needs remain unmet.

Identifying the genetic basis of local adaptation is a key goal in evolutionary biology. Allele frequency clines along environmental gradients, known as genotype-environment associations (GEA), are often used to detect potential loci causing local adaptation, but GEA are rarely followed by experimental validation. Here, we tested loci identified in three different moisture-related GEA studies on .

Epigenetic alterations are hallmarks of cancer, with histone modifiers playing critical roles in gene transcription, DNA homeostasis, and other nuclear functions. Lysine-specific demethylase 1 (LSD1), a key regulator of H3K4 methylation, has emerged as a promising pharmacological target in cancer treatment, including leukemia. Acute lymphoblastic leukemia (ALL), the most common pediatric cancer, remains a significant therapeutic challenge due to limited understanding of how epigenetic therapy impacts leukemia dissemination.
