DJ-1 mRNA expression after exposure to HTT2800, Sumi black, and cup-stacked carbon nanotubes. MES O-1 cells were exposed to diverse carbon nanomaterials for 4 days; mRNA levels of DJ-1 were determined by quantitative real-time polymerase chain reaction and normalized to G glyceraldehyde 3-phosphate dehydrogenase.
Notes: n = 3, mean ± standard error of the mean, *P < 0.01.
Abbreviations: DM, dispersant medium containing 0.001% gelatin; SB, Sumi black; CSCNT, cup-stacked carbon nanotubes.
