Abstract: Primer extension experiments carried out in the absence of one deoxyribonucleoside-triphosphate suggested that mutations did not affect the accuracy of the RT, except for V75A, V75F, V75I, and to a lesser extent V75T.
Abstract: Specific DNA polymerase activities of mutant RTs bearing amino acid substitutions at position 75 (i.e., V75A, V75F, V75I, V75L, V75M, V75S and V75T) were relatively high.
Abstract: Steady- and pre-steady-state kinetics demonstrated that the increased fidelity of
2'-deoxy-4'-C-ethynyl-2-halo-adenosines active against drug-resistant human immunodeficiency virus type 1 variants.

Abstract: The V75I mutation is part of the multidrug resistance pathway that enhances viral resistance to many of the best RT inhibitors approved for the treatment of HIV.
Abstract: The target of acyclovir in HIV-infected cells is validated as HIV reverse transcriptase (RT) by the emergence of the RT variant V75I under the selective pressure of acyclovir.
Sequential emergence and clinical implications of viral mutants with K70E and K65R mutation in reverse transcriptase during prolonged tenofovir monotherapy in rhesus macaques with chronic RT-SHIV infection.
Result: V75I/L, E194K, G196R, L214F) were already present in some viruses obtained prior to tenofovir therapy, and most have previously been described in RT-SHIV isolates obtained from untreated macaques.

Abstract: One case (1.1%) had the reverse-transcriptase mutation, V75I.
HIV-1 subtype B protease and reverse transcriptase amino acid covariation.
Abstract: Different patterns of covariation were frequently observed for different mutations at the same position including the RT mutations T69D versus T69N, L74V versus L74I, V75I versus V75M, T215F versus T215Y, and K219Q/E versus K219N/R, and the protease mutations M46I versus M46L, I54V versus I54M/L, and N88D versus N88S.

Abstract: The original isolate carried the MNR mutations S68G, V75I, F77L, F116Y and Q151M, the lamivudine mutation M184V, the NNRTI mutation K103N and the yet unreported K70S.

Abstract: Reverse transcriptase inhibitor-associated primary resistance mutations were found in 5 (9.8%) samples: Y188C in 2 cases, and L100I, M184V, and V75I in 1 case each, although all of these mutations were found as minor populations.
Clonal analyses of HIV quasispecies in patients harbouring plasma genotype with K65R mutation associated with thymidine analogue mutations or L74V substitution.
Abstract: At the enzyme level, the addition of the A62V mutation to V75I/F77L/F116Y/Q151M moderately (3.4-fold) reversed the resistance to DXG-TP.
Abstract: In this study, we evaluated the antiviral activity of (-)-beta-D-1',3'-dioxolan guanine (DXG) towards mutant HIV-1 containing V75I/F77L/F116Y/Q151M (V75Icomplex) and A62V/V75I/F77L/F116Y/Q151M (A62Vcomplex) in MT-2 cells.
