Prolonged hypoxia induced differential protein signatures in BRCA1 +/- triple negative breast cancer cell lines
This project of the Baltic-German University Liaison Office is supported by the German Academic Exchange Service (DAAD) with funds from the Foreign Office of the Federal Republic Germany.
Breast cancer is the most common cancer in Europe (age standardized incidence 109 cases per 100 000 population, accordingly, in 2012), and results in substantial socioeconomic burden on the society. Triple-negative breast cancer (TNBC) is associated with a poor prognosis and defines a subgroup of patients who do not benefit from endocrine or anti-HER2 therapy. Although TNBC has relative chemo-sensitivity it is still characterized by aggressive clinical behaviour. In our previous studies we have proved that relapse rates and breast cancer-specific survival (BCS) outcomes for BRCA1 positive (+) TNBC is significantly better compared to BRCA1 negative (-) TNBC. This finding is in the line with proposed involvement of altered DNA double strand break (DSB) repair system in therapy response.
