Paclitaxel har vist sig at være genotoksisk in vivo (micronucleustest på mus); men det inducerede ikke mutagenicitet i Ames- testen eller Chinese hamster ovary/ hydoxantine- guanine phosphoribosyl transferase (CHO/ HGPRT) genmutations- testen.
Paclitaxel has been shown to be genotoxic in vivo (micronucleus test in mice), but it did not induce mutagenicity in the Ames test or the Chinese hamster ovary/ hypoxanthine-guanine phosphoribosyl transferase (CHO/ HGPRT) gene mutation assay.
