KC1 = is electrophilic, KC2 = is genotoxic, KC3 = alters DNA repair or
causes genomic instability, KC4 = induces epigenetic alterations, KC5 = induces
oxidative stress, KC6 = induces chronic inflammation, KC7 = is
immunosuppressive, KC8 = modulates receptor-mediated effects, KC9 = causes
immortalization, KC10 = alters cell proliferation, cell death, or nutrient
supply. Supporting information for the different arrows can be found in the text
or are considered by the working group to be biologically plausible. KCs are
color coded according to the association between KCs and 86 chemicals
carcinogenic to humans (International Agency for Research on Cancer Group 1
Agents) as determined by Krewski et al. [49].
