The Fetal Environment and the Development of Hypertension-The Epigenetic Modification by Glucocorticoids.

Intrauterine growth restriction (IUGR) is a risk factor for postnatal cardiovascular, metabolic, and psychiatric disorders. In most IUGR models, placental dysfunction that causes reduced 11β-hydroxysteroid dehydrogenase 2 (11βHSD2) activity, which degrades glucocorticoids (GCs) in the placenta, resulting in fetal GC overexposure. This overexposure to GCs continues to affect not only intrauterine fetal development itself, but also the metabolic status and neural activity in adulthood through epigenetic changes such as microRNA change, histone modification, and DNA methylation.

Recent advances in biomarkers for senescence: Bridging basic research to clinic.

In this review, we review the current status of biomarkers for aging and possible perspectives on anti-aging or rejuvenation from the standpoint of biomarkers. Aging is observed in all cells and organs, and we focused on research into senescence in the skin, musculoskeletal system, immune system, and cardiovascular system. Commonly used biomarkers include SA-βgal, cell-cycle markers, senescence-associated secretory phenotype (SASP) factors, damage-associated molecular patterns (DAMPs), and DNA-damage-related markers.

Hypoxia Modulates Sodium Chloride Co-transporter via CaMKII-β Pathway: An In Vitro Study with mDCT15 Cells.

Background: Hypoxia plays a crucial role in regulating various cellular functions, including ion-transport mechanisms in the kidney. The sodium-chloride co-transporter (NCC) is essential for sodium reabsorption in the distal convoluted tubule (DCT). However, the effects of hypoxia on NCC expression and its regulatory pathways remain unclear.
