CXCR4 and diabetic kidney disease: As shown in Figure 1J, both CXCR4 (red) and β-catenin (green) were induced and colocalized in the glomeruli of mice in hypertensive nephropathy induced by chronic infusion of angiotensin II (Ang II), diabetic nephropathy in genetic db/db mice, and remnant kidney model induced by 5/6NX.
