Fig. 4From: RBM5-AS1 promotes radioresistance in medulloblastoma through stabilization of SIRT6 proteinDepletion of RBM5-AS1 suppresses tumor growth and increases radiosensitivity in vivo. A, B DAOY xenograft tumors were exposed to irradiation (IR), and tumor growth was determined. A Macroscopic view of xenograft tumors. C Immunohistochemical staining for Ki-67 in xenograft tumor sections. Scale bar = 100 μm. (D) TUNEL staining in xenograft tumor sections. Scale bar = 100 μm. *P < 0.05Back to article page
