Top: Steady-state levels of IL-1β mRNA induced by E. coli serotype O55:B5 LPS were reduced by brief hypoxia. Total cellular RNA was loaded and run on agarose gels, blotted, and hybridized with murine 32P-labeled specific cDNA probes at the designated time points shown. +, presence; −, absence. Bottom: A mean densitometry of IL-1β signals was obtained from triplicate samples and then normalized to a similar mean densitometry value for glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
