Most host cell ncRNAs are less enriched in virions than 7SL RNA. (AD) Northern blotting was used to compare the levels of specific ncRNAs in virions (lane 4) with their levels in an arbitrary amount of cellular RNA (lane 2). As controls, we examined RNA from uninfected cells (lane 1) and from the culture media of these cells (lane 3). To facilitate comparisons between RNAs, the enrichment of each RNA was normalized to that of 7SL RNA. (AC) Analyses of virus produced in infected and uninfected CEM-SS cells. (D) Analyses of virus produced by transfecting HEK293T cells with pNL4-3.
