SERPING1 and central nervous system cancer: To test the effect of KD on the pro-inflammatory transcriptional profile of glioma cells, we sorted Luc+-GL261 cells from mouse brains (Fig. S3C) and found that none of the tested genes were modulated (Fig. 3E), while others, such as Serping1, H2-T23, and CD44 were under the limit of detection.
