1 Here we identified STAT5a as a chemoresistance inducer that regulates the expression of ABCB1 in breast cancer and can be targeted by pimozide, an FDA-approved psychotropic drug. Pimozide signal transducer and activator of transcription 5A Homo sapiens
2 First, we found that STAT5a and ABCB1 were expressed at higher levels in doxorubicin-resistant cell lines and chemoresistant patients, and their expression was positively correlated. Doxorubicin signal transducer and activator of transcription 5A Homo sapiens
3 Subsequently, the efficacy of pimozide in inhibiting STAT5a and sensitizing doxorubicin-resistant breast cancer cells was tested. Pimozide signal transducer and activator of transcription 5A Homo sapiens
4 Targeting STAT5a might be a promising strategy for treating doxorubicin-resistant breast cancer. Doxorubicin signal transducer and activator of transcription 5A Homo sapiens
