Result: One participant in the boosted PI group, who was on a regimen of ritonavir-boosted darunavir plus abacavir/lamivudine, developed virological failure with a treatment-emergent L74V resistance substitution in RT at week 4.

Result: The most frequent mutation of resistance to NRTI worldwide is M184V/I, followed by K65R/N, L74V/I, Y115F, and Q151M, and the most prevalent for FSU_A is M184V, followed by K65R/N.

Introduction: As expected, patients failing AZT-based therapy did not develop mutations K65R, K70E, L74V, or Y115F, and only rarely were DRMs from the Q151M complex seen.
HIV-1 with HBV-associated Q151M substitution in RT becomes highly susceptible to entecavir: structural insights into HBV-RT inhibition by entecavir.
Method: Antiviral assays (p24 assay) using wild-type HIV-1 (HIV-1WT) and replicable HIV-1 variants (HIV-1Q151M, HIV-1Q151M/Y115F/F116Y, and HIV-1Q151M/I63V/L74V) were also conducted as previously described.
Result: HIV-1Q151M, HIV-1Q151M/Y115F/F116Y, and HIV-1Q151M/I63V/L74V propagated slower than did HIV-1WT, but HIV-1Q151M/Y115F/F116Y reached similar or slightly greater supernatant p24 levels on day 9 than did HIV-1WT.
Result: I63V/L74V thus weaken the stabilization of bound ETV-TP at the N-site, which might drastically decrease ETV-MP incorporation into primer DNA.
Result: In contrast to
Chemical system biology based molecular interactions to identify inhibitors against Q151M mutant of HIV-1 reverse transcriptase.
Result: We created 5 HBV RT-mimicking HIV-1 RT mutants in this study: RTQ151M, RTQ151M/F160L, RTQ151M/G112S/D113A, RTQ151M/Y115F/F116Y, and RTQ151M/I63V/L74V (Table 1).
Discussion: Among the total of 8 amino-acid substitutions introduced in this study (Table 1), Q151M, Y115F, F116Y, and
