Antiangiogenic and Antitumor Therapy for Retinoblastoma with Hypoxia-Inducible Factor-1α siRNA and Celastrol Co-Delivery Nanomicelles

Retinoblastoma (RB) makes up about 3% of all childhood malignancies. Chemotherapy is commonly applied for RB treatment, while the clinical effectiveness varies significantly due to the cancer therapeutic resistances. Hypoxic tumor microenvironment, a hallmark of all tumors, is strongly associated with malignant progress and therapeutic resistances. The hypoxia mainly promotes the angiogenesis by upregulating pro-angiogenetic pathways. In this...
