Importantly, small-molecule screening identified T7117 as an inhibitor that disrupts the TRIM25-HIF-1α interaction, suppresses tumor growth, and enhances temozolomide efficacy. Together, our findings uncover a previously unrecognized ubiquitin mechanism that stabilizes hydroxylated HIF-1α under normoxia, revealing the TRIM25-HIF-1α axis as a driver of GBM pseudohypoxia and a potential therapeutic target.
Our study identifies key immune contributors correlated with response to neoadjuvant therapies and a panel of TAAs in non-responders. These findings support the development of TAA-targeted therapeutic vaccines and combination strategies incorporating ICB to overcome resistance in non-responders.
p53-R248W confers selective doxorubicin resistance to multiple cancer cells through TOP2A suppression and CYP1A1/A2 overexpression. These findings highlight the mutation specific mechanism of doxorubicin resistance that might result in poor response and needs to be considered during treatment plan.
