Effect of Efavirenz (EFV) treatment on cellular proliferation and viability of Hep3B cells (A) Cell count over 3 days using a haemacytometer revealed a concentration-dependent inhibition of cellular proliferation. **P < 0.01, ***P < 0.001 versus vehicle. (B) Representative inverted light microscopy images (10x) of cell culture treated with EFV for 24 h. (C) MTT assay of exponentially growing cells after 24 h of culture in the presence of EFV. Data (mean ± SEM, n= 3–6) were analysed by a one-way anova multiple comparison test followed by Newman–Keuls test, significance versus vehicle *P < 0.05.
