RPS6KA1 and glioblastoma: In fact, the RSK1 signature that we used to infer RSK1 protein in datasets of GBM and LGG combines genes associated with immune infiltrate, such as CD68, with genes associated with mesenchymal subtype, such as LAPTM5. Nevertheless, only 10/33 genes in our signature were shared with the signatures used to predict immune cell types and GBM subtypes.
