FASN and cancer: Of note, GBM cancer cells were also observed to display a high expression of the above-mentioned fatty acid synthesis and desaturation genes (FASN, SCD and FADS2) relative to most other cell types in our scRNA-seq data set (Supplementary Figure S2C), with the exception of oligodendrocytes and myeloid cells, for which SCD was also highly expressed, in agreement with prior reports (33).
