Fig. 4From: Inflammatory Mediators Regulate Cathepsin S in Macrophages and Microglia: A Role in Attenuating Heparan Sulfate InteractionsDecreased cathepsin S mRNA in LPS-treated primary rat alveolar macrophages. Total RNA was isolated from 5 × 106 rat alveolar macrophages treated with increasing concentrations of LPS for 4 hr (A) or treated with 100 ng/ml LPS for various durations (B) and subject to Northern analysis (15–20 µg/lane). RNA blots were probed with 32P-labeled cDNAs specific for cathepsin S.Back to article page
