Molecular Biology Reagents To overexpress the exogenous PITX2, MCF7 cells were transfected with pPM-His-PITX2 or pPM-His vector (GenScript, Nanjing, China) using Lipofectamine 3000 (Thermo Fisher Scientific), followed by Neomycin selection (200 μg/mL, Invitrogen, Carlsbad, CA) according to the manufacturer’s instructions.  Get A Quote

摘要

Although the interferon α (IFNα) signaling and the paired-like homeodomain transcription factor 2 (PITX2) have both been implicated in the progression of breast cancer (BCa), it remains obscure whether these two pathways act in a coordinated manner. We therefore aimed to elucidate the expression and function of PITX2 during the pathogenesis of endocrine resistance in BCa.
