Figure 1: Expression of KIF5A and KIF18A at 4, 8, and 24 hour time points, following the addition of 10 μg/cm2 crocidolite asbestos (solid line), chrysotile asbestos (dotted line), silicon dioxide (dashed-dotted line), or Hanks Balanced Salt Solution (dashed line). A Bonferroni adjusted p-value of p ≤ 0.01 was considered significant, within each time point. Levels of significance are denoted by the following; (*): crocidolite and SiO2 induced greater kinesin expression than HBSS or chrysotile, (+): crocidolite induced greater kinesin expression than HBSS, (#): crocidolite induced greater kinesin expression than HBSS, chrysotile and SiO2, (~): crocidolite and SiO2 induced greater kinesin expression than HBSS or chrysotile and SiO2 induces greater expression than crocidolite, (^) crocidolite induced greater kinesin expression than HBSS or chrysotile, while only SiO2 induced higher expression than HBSS.
