Figure 4From: Human herpesvirus 6A induces apoptosis of primary human fetal astrocytes via both caspase-dependent and -independent pathwaysHHV-6A activates PARP cleavage and up-regulates Bax/Bcl-2 ratio. a. PARP in mock-infected and HHV-6A-infected cells was analyzed by Western blotting. b. Expressions of Bcl-2 and Bax were detected by Western blots using anti-Bcl-2 and anti-Bax antibodies, respectively. β-actin was used as a loading control. Quantitative values of Bcl-2 and Bax are the mean ± SD from three independent experiments (**P < 0.01, ***P < 0.001).Back to article page
