Colchicine （0.0025 mmol/L, 0.0050 mmol/L, 0.0075 mmol/L） was used as a positive control.RESULTS： THH could significantly inhibit the assembly of isolated porcine brain tubulin at all tested concentrations.CONCLUSION： THH is capable of inducing aneuploidy in mammals via tubulin polymerization inhibition pathway and may pose a genetic risk to human beings.展开更多
