Tazelaar, MD, Christopher G.A. McGregor The Annals of Thoracic Surgery Volume 66, Issue 2, Pages 318-323 (August 1998) DOI: 10.1016/S0003-4975(98)00552-9
Fig 1 Polymerase chain reaction of DNA extracted from rat lungs. A 356-bp band for ecNOS DNA is seen only in ecNOS-transduced lungs. (β-Gal = β-galactosidase.) The Annals of Thoracic Surgery 1998 66, 318-323DOI: (10.1016/S0003-4975(98)00552-9)
Fig 2 Reverse transcriptase polymerase chain reaction of messenger RNA extracted from rat lungs. A 250-bp band for ecNOS messenger RNA is seen only in ecNOS-transduced lungs. Messenger RNA for G3PDH was detected in all samples (450 bp). The Annals of Thoracic Surgery 1998 66, 318-323DOI: (10.1016/S0003-4975(98)00552-9)
Fig 3 Immunostaining for ecNOS in β-galactosidase (β-Gal)-transduced, transplanted lungs (A) and ecNOS-transduced, transplanted lungs (B). Arrows denote positive staining. Airway epithelium and vascular endothelial cells stained positively for eNOS in lungs from β-galactosidase–transduced lungs (arrows). Pneumocytes showed positive staining for ecNOS only in ecNOS-transduced lungs (arrow). (×200 before 50% reduction.) The Annals of Thoracic Surgery 1998 66, 318-323DOI: (10.1016/S0003-4975(98)00552-9)
Fig 4 Calcium-dependent (Ca Dep; black bars) and calcium-independent (Ca Indep; white bars) nitric oxide synthase activity in nontransfected lungs (CONTROLS) and lungs transfected with β-galactosidase (β-GAL) or endothelial nitric oxide synthase (ecNOS). Data are shown as mean ± standard error of the mean, n = 4 in each group. Asterisk denotes statistical significance from control (analysis of variance, p < 0.05).
