3. Figure 2
Expression of the HBV core mRNA in liver tissues of patients with occult HBV infection. (A) Total RNA isolated from tumor (t) and nontumor (nt) liver specimens of 3 individual cases (a, b, and c) was analyzed by reverse-transcription PCR and the use of specific primers for core mRNA expression. (B) β-actin mRNA was amplified as an internal control for the integrity of the RNA and the quantity loaded per lane. (A and B) m, DNA molecular-weight marker (sizes along left margin). (C) Southern blot analysis was performed to confirm the specificity of the results. +, positive control; −, negative control.
