Figure Lengend Snippet: TMZ elevates reactive oxygen species (ROS) levels, including H 2 O 2 . In resistant GBM cells, moderate H 2 O 2 activates AKT, driving SH3GLB1 expression and sustaining drug resistance, whereas excessive H 2 O 2 (e.g., following HNE co-treatment) suppresses SH3GLB1 and impairs resistance. Furthermore, HgCl 2 downregulates mitochondrial aquaporin-9 (AQP9), reducing H 2 O 2 flux and SH3GLB1 expression. This schematic illustrates how H 2 O 2 levels, AKT activation, and AQP9 modulation collectively shape SH3GLB1-driven resistance
