A minimum signal but greater than genotoxicity threshold (sirtuininhibitor1.three GFP fold induction) was obtained at lower concentrations. Outdoors the optimal linear concentration variety, GFP signals had been still detected but no longer within a linear proportional relation of signal intensity to investigated concentrations. The signal tended to reduce when exposed to levels above the highest concentrations with the linear range as the result of cell death. In comparison from the 3 coexpressing systems, the CYP3A4 + RAD54 technique was considerably more sensitive and particular for identifying AFB1 and BaP than the CYP2B6 + RAD54 program, but nonspecific for NDMA. Whereas the CYP2B6 + RAD54 program was shown to be much more precise for detecting NDMA but less particular for AFB1 than the CYP3A4 + RAD54 method, and nonspecific for BaP. The CYP2D6 + RAD54 was neither sensitive nor particular for each of the three procarcinogens. In respect to genotoxic carcinogen (MMS, a positive control), both coexpressing systems (CYP3A4/CYP2B6/CYP2D6 + RAD54) and single expressing program (RAD54) exhibit a higher sensitivity and specificity in determination of MMS, though the method carrying handle vectors (NCs) shows.
