Fig 5. Effect of shapes of single and multiwalled carbon nanotubes (SWCNTs, MWCNTs) upon exposure on Atm gene methylation.

Bars connect exposure groups with significant methylation difference. In panels, box plot describes the median (line across the box), inter-quartile ranges and maximum and minimum values (whiskers). Outliers are shown as colored circles outside the ends of whiskers. Asterisk sign (*) shows significance levels at p = 0.5 (dunn’s statistics). Atm: ataxia telangiectasia mutated; Trp53: tumor protein P53.
