(A) Differentiated podocytes were infected with NL4-3 ΔEnv virions pseudotyped with HXB2 or VSV-G envelopes. At indicated times, cellular RNA was isolated, reverse transcribed and analyzed by real-time RT-PCR. Expression of Nef2 mRNA was normalized to GAPDH and the level of Nef2 mRNA at 3 h post-infection with HXB2 pseudotyped HIV-1 was set to 100%. (B) Relative expression of genomic unspliced (usRNA) RNA, multiply spliced RNA (msRNA) and Nef2 mRNA in AD8 virions were quantitated and normalized against 7SL RNA (Onafuwa-Nuga, Telesnitsky, and King, 2006). Expression of virion usRNA was set to 100%.
