Figure 6. CDDP (cisplatin) treatment reduced the expression of TP53 and FIR in ESCC cells.
(A) Esophageal cancer cell lines (TE2) were exposed to CDDP. The expression of TP53, and FIR was decreased, whereas that of Notch1 was increased. (B) Cyclin E was increased by CDDP treatment (arrows). (C) γH2AX was an indicator of DNA damage as well as T.Tn cells that has pathogenic TP53 mutation (arrows). (D) 5FUtreatment increased cyclin E expression in esophageal cancer cells (TE1 and TE2 cells).
