Steatosis is not linked with endogenous retrovirus reactivation. (a) Northern blot analysis of endogenous MLVenv expression in liver. Hybridization with a Gapdh probe was used to show equal loading of the lanes. (b) Quantification of the intensity of the band from the northern blot. The histogram indicates the relative difference (after normalization for Gapdh expression) in the abundance of MLVenv transcripts with respect to levels observed in wild-type mice, which were set at 1. The error bars represent SEM.
