Dynamic Fluoroleucine PET Detects Impaired Cardiac Leucine Uptake Before Hypertensive Left Ventricular Hypertrophy Develops

This paper uses [18F]FLE-PET/CT to detect reduced cardiac leucine uptake in hypertensive rats before LVH develops, suggesting it as an early marker for cardiometabolic dysfunction.

Protein Phosphatase 2A Subunit B55 Alpha is Required for Angiotensin Type 2 Receptor Elicited Natriuresis

This study shows that PP2A B55 binds to activated AT2R and is essential for AT2R signaling, natriuresis, and intracellular trafficking in renal proximal tubule cells.
