Ghrelin and peptide YY in youth: are there race-related differences?
The lower suppression of ghrelin in AA, but not the lower PYY levels, correlates with insulinemia and insulin resistance. Less ghrelin suppression and PYY elevation after a meal in black youth could be a potential mechanism of race-related differences in hunger/satiety predisposing to risk of obesity.
CTGF is an important mediator of high glucose-induced podocyte damage and decreases the protein level of podocalyxin by the ERK1/2 pathway. CTGF-specific siRNA can alleviate high glucose-induced podocyte injury, suggesting its potential value in treatment of diabetic nephropathy.
