Information from provider
| Provider | John Collard |
| Provider affiliation | Research - Animal Facility, The Netherlands Cancer Institute |
| Genetic information | Mice that are deficient for the Rac activator Tiam1. |
| Phenotypic information | Mice do not have an obvious phenotype and are fertile. However tumorigenicity is highly affected. In general tumor formation and growth is reduced but metastasis is enhanced. |
