Effects of CCR2 deficiency on Notch ligand expression. Quantitative RT-PCR of normoxic and hypoxic lungs from Ccr2−/− mice show significantly decreased Jagged-1 expression; these mice also had significantly increased baseline expression of Jagged-2, Delta-like (DLL)-1, and DLL-4. Expression of Jagged-2 and DLL-4 were further enhanced with hypoxic exposure (n = 5–7 animals per group). *P < 0.05; **P < 0.01; ***P < 0.001.
