APOBEC3F and APOBEC3G (hA3F and hA3G) are part of an innate mechanism of antiretroviral defense. The human immunodeficiency virus type 1 (HIV-1) accessory protein Vif targets both proteins for proteasomal degradation. Using mRNA from peripheral blood mononuclear cells of 92 HIV-infected subjects not taking antiretroviral therapy and 19 HIV-uninfected controls, we found that hA3F (P < 0.001) and hA3G (P = 0.016) mRNA levels were lower in HIV-infected subjects and were positively correlated with one another (P = 0.003). However, we found no correlation in the abundance of either hA3F or hA3G mRNA with either viral load or CD4 counts in HIV-infected subjects.
