Stable transfection of esophageal cancer cells with RUNX3 slightly inhibited cell proliferation in vitro, enhanced the antiproliferative and apoptotic effects of TGF-beta and increased radiosensitivity in conjunction with Bim induction.
The expression of RUNX3 mRNA was quantified by real-time reverse transcription polymerase chain reaction using Taq Man PCR in 15 esophageal cancer cell lines (TE1-15) and 70 esophageal squamous cell carcinoma (ESCC) specimens and their paired normal esophageal mucosa.
Here we conducted a systematic review and meta-analysis to quantitatively evaluate the effects of RUNX3 promoter methylation on the incidence of esophageal cancer.
CpG methylation of O<sup>6</sup>-methylguanine-DNA methyltransferase promoter had a positive association in the development of esophageal cancer (p < 0.05), whereas runt-related transcription factor 3 promoter methylation showed no significant association (p = 1.0) to develop esophageal cancer.
