In this thesis, the permanent reduction of the protein expression of uPAR combined with uPA or with IGF-1R respectively lead to a reduced tumour behaviour in vitro and could represent an approach for an improved treatment of TNBC. IGF-1R was confirmed as a direct interaction partner of uPAR. In addition Cyr61, YB-1 und Caprin-1 were identified as new interaction partners of uPAR and as new potential therapeutic targets. The expression of Cyr61 and YB-1 significantly correlated with the expression of tumour-relevant proteins and the tumour grade in a TNBC cohort.
