Non-proliferating WM266.4 Cells Exhibit the Gene Expression Signature of DNMT1 Inhibition
(A) Fragments per kilobase of exon per million reads mapped (FPKM) of MKI67 in the 61 single cell-derived cDNA libraries, separated into Non-proliferating (23 cells, FPKM <1) and Proliferating (38 cells, FPKM >1) group.
(B and C) FPKM of cell proliferation-related genes (TK1, MCM7, TOP2A and PCNA) in Non-proliferating (NP) and Proliferating (P) group in the single cell-derived cDNA libraries.
(D) GSEA results with the indicated gene sets between Non-proliferating (NP) and Proliferating (P) groups.
(E) Representative images of WM266.4 brain metastasis, stained for DNMT1. Green: WM266.4 cells, Blue: DAPI, Red: DNMT1. Scale bar, 100 μm.
(F) Size of lesions (number of cells) and DNMT1-positive ratio in SC, MC, MM, and EM at day 30. Av., average of DNMT1-positive ratio (n = 37 [SC], 32 [MC], 39 [MM], and 21 [EM]). Data are mean (B and C).
