After publication of the Research Article “Targeting GOLPH3L improves glioblastoma radiotherapy by regulating STING-NLRP3–mediated tumor immune microenvironment reprogramming” by S. Sun et al., the authors found two errors in the Supplementary Materials. The bioluminescent image of CT2A-bearing mice with radiotherapy (RT) (day 17) in fig. S8E mistakenly duplicated the image of Nlrp3 KD GL261-Luci–bearing mice (day 17) in fig. S22B. The bioluminescent image of GL261R-Luci–bearing mice in the RT group (day 23) in fig. S49C mistakenly duplicated the image of GL261-Luci–bearing mice in the Mock+RT group (day 23) in fig. S42B. Figures S8E and S49C have been corrected, and the quantification and interpretation of the data and the conclusions of the paper are not affected.
