Result: In comparison, mutations such as K65R, K70E, L74V, Q151M, and M184V increase the selectivity of RT for incorporation of natural deoxynucleoside triphosphate substrate versus the NRTI-triphosphate.

Abstract: The major mutations, which were mainly K103N and Q151M, were less frequent in China than those in other countries.

Abstract: Three clinically relevant mutant HIV variants, including one containing the Q151M mutation conferring multinucleoside resistance, were equally as sensitive to BLM as the wild-type HXB2 strain.

Abstract: Insertions at amino acid position 69 and Q151M mutations (with or without M184V) reduced SPD754 susceptibility 5.2-fold and 14- to 16-fold, respectively (these changes gave values comparable to or less than the corresponding values for zidovudine, lamivudine, abacavir, and didanosine).
Chemical system biology based molecular interactions to identify inhibitors against Q151M mutant of HIV-1 reverse transcriptase.
Abstract: In this study, we measured the antiviral activity of FTC and 3TC against HIV-1 containing K65R, Q151M, and K65R/Q151M mutations.
Abstract: Overall, this study demonstrated that K65R and K65R/Q151M related drug resistance to FTC and 3TC was mainly due to a significant decrease in the rate of incorporation.
Abstract: The Q151M mutation confers reduced susceptibility to many of the approved anti-HIV nucleoside analogues with the exception of 3TC and teno
Abstract: The double mutation K65R/Q151M has been shown to be more resistant to many NRTIs than either of the single mutations alone.

Abstract: An increased genetic barrier was calculated for I82A (subtypes C and G), V108I (subtype G), V118I (subtype G), Q151M (subtypes D and F), L210W (subtypes C, F, G, and CRF02_AG), and P225H (subtype A) (P < 0.001 compared with subtype B).
Clinical and genotypic correlates of mutation K65R in HIV-infected patients failing regimens not including tenofovir.
Abstract: Among genotypic correlates, the presence of M184V and NAMs seems to be protective for the emergence of K65R, while a strong positive correlation was found with the Q151M complex mutation.
Abstract: However, exposure to abacavir and/or efavirenz, presence of Q151M and/or L100I, and prior AIDS may favor the selection of this mutation.
The K65R mutation in human immunodeficiency virus type 1 reverse transcriptase exhibits bidirectional phenotypic antagonism with thymidine analog mutations.
Abstract: Among samples with K65R, a strong negative association was evident with the TAMs M41L, D67N, L210W, T215Y/F, and K219Q/E (P<0.005) but not with other NRTI mutations, including the Q151M complex.
