Fig. 8. Neutral red inhibits cell progression in vitro and tumor cell growth in vivo.
A KYSE150 cells were treated with NR, U0126, or a combination, and cell proliferation was detected by colony formation assay. B KYSE150 cells were treated with NR, U0126, or a combination, and cell migration and invasion were examined by Transwell assays. C Representative images of tumors excised from mice injected with PBS, NR, U0126, or a combination of NR and U0126. D, E The volume and weight of each tumor were measured during the indicated periods. F Schematic representation of the potential mechanism of USP4 in ESCC progression. *P < 0.05, ***P < 0.001.
