On the other hand, 44 genes with higher correlation coefficient in CE-low tumors (differential correlation score < −0.4) were classified as CE-low associated genes including RASIP1, CRIP1, ARHGAP29, FERMT2, ERG, FOXF2, ABCG2, TJP1, and COL1A2 (Figure 2B, blue triangles; Table S3). Here, ERG is linked to cholesteryl ester measurement.
