Deletion of the enhancer inhibits tumorigenesis in vitro and in vivo. (A) KEGG analysis showing tumor cell growth after enhancer deletion. X axe: Gene ratio (number of counts/total genes); Y axe: Altered signaling pathways, tumorigenesis related pathways were shown in the data. The size of dot represents gene counts and the color represent P value. (B) Plate clone formation assay demonstrated that tumor formation ability was significantly reduced in enhancer-deleted OCM1 cells. (C) Suppressive effects on tumor volume in enhancer-deleted OCM1 cells in a subcutaneous xenograft model. Data are presented as the mean ± SD and the differences between two groups were calculated by unpaired two-tailed Student's t-test. * P < 0.05, ** P < 0.01. (D, E) Animal imaging system demonstrated the suppressive effects on tumor bioluminescent signals in enhancer-deleted OCM1 cells in orthotopic xenografts. (F) Suppressive effects on weight in enhancer-deleted OCM1 cells in orthotopic xenografts. Data are presented as the mean ± SD and the differences between two groups were calculated by unpaired two-tailed Student's t-test. * P < 0.05, ** P < 0.01. (G) Prolonged survival time in enhancer-deleted OCM1 cells in orthotopic xenografts. (H) Fewer metastatic spots in enhancer-deleted OCM1 cells in the metastatic model.
