Kidney Programming and Hypertension: Linking Prenatal Development to Adulthood.

The complex relationship between kidney disease and hypertension represents a critical area of research, yet less attention has been devoted to exploring how this connection develops early in life. Various environmental factors during pregnancy and lactation can significantly impact kidney development, potentially leading to kidney programming that results in alterations in both structure and function. This early programming can contribute to adverse long-term kidney outcomes, such as hypertension. In the context of kidney programming, the molecular pathways involved in hypertension are intricate and include epigenetic modifications, oxidative stress, impaired nitric oxide pathway, inappropriate renin-angiotensin system (RAS) activation, disrupted nutrient sensing, gut microbiota dysbiosis, and altered sodium transport. This review examines each of these mechanisms and highlights reprogramming interventions proposed in preclinical studies to prevent hypertension related to kidney programming. Given that reprogramming strategies differ considerably from conventional treatments for hypertension in kidney disease, it is essential to shift focus toward understanding the processes of kidney programming and its role in the development of programmed hypertension.
