Article Abstract
Natural killer (NK) cells are major innate lymphocytes. NK cells do not require prior antigen exposure to mediate antitumor cytotoxicity or proinflammatory cytokine production. Since they use only nonclonotypic receptors, they possess high clinical value in treatment against a broad spectrum of malignancies. Irrespective of this potential, however, the transcriptional regulation that governs human NK cell development remains far from fully defined. Various environmental cues initiate a complex network of transcription factors (TFs) during their early development, one of which is GATA2, a master regulator that drives the commitment of common lymphoid progenitors (CLPs) into immature NK progenitors (NKPs). GATA2 forms a core heptad complex with six other TFs (TAL1, FLI1, RUNX1, LYL1, LMO2, and ERG) to mediate its transcriptional regulation in various cell types. Patients with GATA2 haploinsufficiency specifically lose CD56bright NK cells, with or without a reduced number of CD56dlm NK cells. Here, we review the recent progress in understanding GATA2 and its role in human NK cell development and functions.

Work-related stress and burnout: Is epigenetic aging the missing link?
Clin Epigenetics
September 2025
Department of Psychiatry and Psychotherapy, Philipps University Marburg, Marburg, Germany.
Background: Work-related stress is a well-established contributor to mental health decline, particularly in the context of burnout, a state of prolonged exhaustion. Epigenetic clocks, which estimate biological age based on DNA methylation (DNAm) patterns, have been proposed as potential biomarkers of chronic stress and its impact on biological aging and health. However, their role in mediating the relationship between work-related stress, physiological stress markers, and burnout remains unclear.

Department of Evolutionary Genetics, Max-Planck Institute for Evolutionary Biology, Plön, Germany.
Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

Biochemistry Division, Chemistry Department, Faculty of Science, Tanta University, Tanta, 31257, Egypt.
Background And Aim: Synthetic dyes in the textile industry pose risks to human health and environmental safety. The current study aims to examine the efficacy of a novel esterase derived from an endophyte fungus in decolorizing diverse dyes, focusing on its production, purification, optimization, and characterization.
Results: Trichoderma afroharzianum AUMC16433, a novel fungal endophyte with esterase-producing ability, was first detected from the cladodes of Opuntia ficus indica by ITS-rRNA sequencing.
Prolonged in vitro anti-bacterial, anti-inflammatory, and surfactant-promoting effects of volatile anesthetics.
BMC Pulm Med

Division of Cellular Pneumology, Priority Area Infections, Research Center Borstel, Leibniz Lung Center, Borstel, 23845, Germany.
Background: Volatile anesthetics are gaining recognition for their benefits in long-term sedation of mechanically ventilated patients with bacterial pneumonia and acute respiratory distress syndrome. In addition to their sedative role, they also exhibit anti-bacterial and anti-inflammatory properties, though the mechanisms behind these effects remain only partially understood. In vitro studies examining the prolonged impact of volatile anesthetics on bacterial growth, inflammatory cytokine response, and surfactant proteins - key to maintaining lung homeostasis - are still lacking.

Department of Neonatology, Zhangzhou Affiliated Hospital of Fujian Medical University, Zhangzhou, Fujian, China.
Background: Red blood cell (RBC) transfusion is a common intervention for anemia in preterm infants; however, its association with bronchopulmonary dysplasia (BPD) remains debated. While biological mechanisms suggest potential harm, the clinical impact of transfusion frequency on BPD incidence and severity remains unclear.
Objective: To investigate whether RBC transfusion frequency is independently associated with the risk and severity of BPD in preterm infants born before 32 weeks of gestation.
