Abstract (original English)

Maternal obesity is a major global health challenge worldwide, significantly increasing the risk of pregnancy complications and long-term metabolic disorders in offspring. Maternal obesity, including associated gestational diabetes, induces epigenetic modifications that can reprogram fetal development and predispose children to lifelong health issues. Long non-coding RNA (lncRNA) H19, one of the first and most extensively studied lncRNAs, plays a pivotal role in developmental programming by regulating gene imprinting, microRNA processing, protein stabilization, and signaling pathways critical for growth and metabolism. Dysregulation of H19 expression under maternal obesity alters the H19/Igf2 (insulin-like growth factor 2) imprinting axis, disrupts skeletal muscle development, and modifies osteogenic and neurogenic pathways, thereby contributing to systemic insulin resistance, metabolic dysfunction, and neuro-disorder in offspring. This review highlights how maternal obesity reprograms offspring health through H19-mediated epigenetic and post-transcriptional regulation, emphasizing its role in the developmental origins of health and disease framework. Understanding the role of H19 offers valuable opportunities to develop targeted interventions that may reduce the transgenerational effects of obesity.
