Infection in the presence of nocodazole had also prevented ICP0 expression (S5B Fig), and there was less nuclear ICP0 in MEF-Impα1-/- (S5Ci Fig) and in MEF-Impα3-/- (S5Di Fig), but not in MEF-Impα4-/- (S5Ei Fig) when compared to MEFwt (S5Ai Fig). The gene discussed is IMPA1; the disease is infection.
