Fig. 6From: Exploring the methylation status of CFTR and PKIA genes as potential biomarkers for lung adenocarcinomaImmunohistochemistry: (A) CFTR is strongly expressed in adjacent normal lung tissue, and decreased expressed in LUAD (magnification ×20, magnification ×40) (B) PKIA is strongly expressed in adjacent normal lung tissue, and in decreased expressed in LUAD (magnification × 20, magnification × 40)Back to article page
