Tumour invasion and metastasis are promoted in mice deficient in tenascin‐X

Abstract

TNX deficiency led to an increase in the production of MMPs, and the increased activity of MMPs may result in the degradation of laminin. Consequently, the melanoma cells inoculated in TNX-/- mice might facilitate invasion and metastasis. These results imply that TNX is required for impeding the invasion and metastasis of tumour cells.
