Abstract: In vitro, HIV-1 mutants resistant to 3'-azido-3'-deoxythymidine (M41L/D67N/K70R/T215Y/K219Q) and (-)beta-L-2',3'-dideoxy-3'-thiacytidine (3TC) (M184V) remain sensitive to DXG.
The Y181C substitution in 3'-azido-3'-deoxythymidine-resistant human immunodeficiency virus, type 1, reverse transcriptase suppresses the ATP-mediated repair of the 3'-azido-3'-deoxythymidine 5'-monophosphate-terminated primer.

Abstract: Resistance to zidovudine (3'-azido-3'-deoxythymidine, AZT) by the human immunodeficiency virus, type 1, requires multiple amino acid substitutions such as D67N/K70R/T215F/K219Q in the viral reverse transcriptase (RT).
Non-nucleoside inhibitors of HIV-1 reverse transcriptase inhibit phosphorolysis and resensitize the 3'-azido-3'-deoxythymidine (AZT)-resistant polymerase to AZT-5'-triphosphate.

Abstract: Here we compared wild type and AZT-resistant (D67N/K70R/T215Y/K219Q) RTs for their ability to unblock the AZTMP-terminated primer by phosphorolysis in the presence of physiological concentrations of pyrophosphate or ATP.

Abstract: The frequencies of T215S/Y/F, M41L, D67N, L210W K70R, K219Q mutations, detectable in plasma samples, conferring resistance to zidovudine were 61.2, 56.2, 36.2, 31.5, 27.5 and 17.5%, respectively.
In vitro study of resistance-associated genotypic mutations to nucleoside analogs.
Abstract: In the remaining six patients, the following patterns of mutations associated with viral resistance were found: one mutation (K70R), which was observed in one patient during the 1st TI and persisted during follow-up; two mutations (L90M, M184V), which were observed in four patients during the 1st TI and were intermittently present or lost following extended TI, treatment reinitiation and/or during subsequent TI; and evolution of two mutations (M184V, K219E) observed in two patients.

Abstract: ELMA is a combination of hybridization and a 1-base extension reaction, and we designed the assay to detect five mutations conferring nucleoside analogue resistance (M41L, D67N, K70R, T215Y, and M184V) and six mutations conferring protease inhibitor resistance (D30N, M46I, G48V, V82A, I84V, and L90M).

Abstract: Nucleoside analog mutations (NAMs) (M41L, D67N, K70R, L210W, T215Y/F and K219Q/E) are associated with reduced susceptibility to most nucleoside analogs and the nucleotide tenofovir.

Abstract: There are several major genetic mutational patterns of resistance and cross-resistance that evolve with the NRTIs including the thymidine analog mutations M41L, D67N, K70R, L210W, T215Y, and K219Q/E/W, the non-thymidine mutations M184V, L74V, and K65R, and the multidrug resistant Q151M complex, as well as others.
