Analysis of cellular mRNAs in transiently and chronically infected woodchucks by RNase protection. The histograms summarize the results obtained from RNase protection experiments with woodchucks in cohorts I and II as well as two uninfected (U) woodchucks (2598 and 2732) and four chronically infected animals (4705, 4707, 4714, and 4723) (the probes used are indicated in the upper right corner of each histogram). Quantitation of the RNase protection analysis was performed with a phosphorimager. The values were expressed in arbitrary units (PSL).
