Popis: Effect of STAT3 decoy oligodeoxynucleotides (ODN) transduced by ultrasound microbubbles combined with ultrasound on the growth of esophageal squamous cell carcinoma and its mechanism were analyzed. EC9706 cells were cultured in vitro and divided into four groups: group E (ultrasound microbubble + ultrasound irradiation), group P (liposome + ultrasound irradiation), group C (ultrasound), and group CC (ultrasound microbubbles). Mutant ODNs were used in groups E and P and the control group was group EC and PC, respectively. Immunofluorescence assay and flow cytometry were used to detect the transfection efficiency of each group. MTT colorimetric assay was performed to analyze the inhibition rate in each group. The effect of STAT3 decoy ODN on the proliferation of esophageal squamous carcinoma cells was calculated. Revese transcription-quantitative PCR (RT-qPCR) and western blotting were performed to detect the expression of the STAT signaling pathway downstream of gene expression levels. The model of subcutaneous transplantation of nude mice was used to show the effect of different transfections and STAT3 decoy ODN on the weight and volume of the transplanted tumor in mice. The cell inhibition rate was higher in group E than in groups P (F=8.382, P
