HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.
