title: Direct tubulin polymerization perturbation contributes significantly to the induction of micronuclei in vivo.
abstract: The computational analysis data presented indicate a significant mechanistic association between the ability of a chemical to cause tubulin polymerization perturbation (TPP), via direct interaction with the protein, and the in vivo induction of micronuclei (MN). Since it is known that TPP is not a genotoxic event, the analyses suggest that the induction of MN by a non-genotoxic mechanism is a significant alternate pathway.
