Additionally, the levels of six of the eight CCT subunits (CCT1, CCT2, CCT3, CCT5, CCT6A and CCT7) were found to be significantly increased in glioblastoma cell‐derived extracellular vesicles, and CCT6A in glioblastoma tissue showed a potential link with EGFR and was identified as a potential prognostic biomarker.146. The gene discussed is CCT5; the disease is glioblastoma.
