26609153 In patients with Alzheimer's disease, QR2 is overexpressed in the insular cotex.
24631540 NQO2-L47 is less stable towards proteolytic digestion and thermal denaturation than NQO2-F47.
23471972 This first structure of a reduced quinone reductase shows that reduction of the FAD cofactor and binding of a specific inhibitor lead to global changes in NQO2 structure and is consistent with a functional role for NQO2 as a flavin redox switch.
23054000 Diplotypes of NQO1 (exon 4 and 6), C-T (OR = 1.56, Pc = 0.007) and T-T (OR = 0.011, Pc = 3.86) was associated with an increased risk for prostate cancer (PCa). NQO2 and MTHFR did not show any risk with PCa.
22770696 NQO1 609C>T and NQO2 -3423G>A polymorphisms do not seem to play any significant role in susceptibility or prognosis of EC in north Indian population.
22266466 results indicate a role of NQO2 in the control of AKT/GSK-3beta/cyclin D1 and highlight the involvement of NQO2 in degradation of cyclin D1, as part of mechanism of chemoprevention by resveratrol
21946896 both NQO1 and NQO2 modulate the efficacy of AC therapy and that NQO2 is associated with tamoxifen toxicity.
21803122 results suggest that the increase in hippocampal QR2 might be a cause of AD or might promote the progression of AD by causing an increase in the toxic quinone levels and consequent loss of cognitive function.
21718050 Selective inhibition of NQO2 over NQO1 can be attributed to the bulky aminoalkylamino substituent at the 5-position, which blocks entrance of the indolequinones into the NQO1 active site.
21555518 NQO2 is a target gene of the BACH1 transcription factor according to ChIP-seq analysis in HEK 293 cells.
