"Collagen prolyl 4-hydroxylase alpha 1 subunit (P4HA1) protein expression is induced in triple-negative breast cancer (TNBC) and HER2 positive breast cancer. Inhibition of P4HA1 sensitizes TNBC to the chemotherapeutic agent docetaxel and doxorubicin in xenografts and patient-derived models. Increased P4HA1 expression correlates with short relapse-free survival in TNBC patients who received chemotherapy."xsd:string
