Additional file 1. Fig. S1. Schematic diagram of glioblastoma treatments. a Glioblastoma cells were treated with IR and UTMD in vitro. b Glioblastoma-bearing mice were treated with IR and UTMD in vivo. IR ionizing radiation, UTMD ultrasound-triggered microbubble destruction, 3-MA 3-methyladenine, BafA1 bafilomycin A1, PGRMC1 progesterone receptor membrane component 1, CTSB cathepsin B, CTSD cathepsin D, RAPA rapamycin, MBs microbubbles, GFP green fluorescent protein, RFP red fluorescent protein, CCK-8 cell counting kit-8, PI propidium iodide, LTG LysoTracker green fluorescent dye, US ultrasound. Fig. S2. Colony formation of glioblastoma cells was measured by clonogenic assay. GL261 and U251 cells were treated with 3-MA (5 mmol/L), BafA1 (10 nmol/L), AG-205 (10 ��mol/L), or RAPA (20 nmol/L) for 1 h followed by IR (2 Gy) or IR plus UTMD treatment for another 24 h. Moreover, GL261 and U251 cells were transfected with lentiviral vectors encoding AGT5 or PGRMC1. Then, cells were treated with UTMD followed by IR (2 Gy) exposure for another 24 h. The conlony formation of glioblastoma cells was measured by clonogenic assay. Values are expressed as mean �� SD (n = 3). *P
