ABSTRACT
This study aimed to observe the differential expression of Annexin-A1 in esophageal squamous cell carcinoma (ESCC) and explored the effect of small interfering ribonucleic acid (RNAi)-Annexin-A1 on the biological behavior of CE81T-0 cells. An immunohistochemical approach was used to detect the expression of Annexin-A1 in 86 pairs of ESCC samples. Quantitative reverse transcription polymerase chain reaction was used to detect the expression of Annexin-A1 in CE81T-0 and CE81T-4 cells, and the expression of Annexin-A1 in CE81T-0 cells was knocked out by RNAi. A methyl-thiazolyl-tetrazolium assay was used to observe the effect of Annexin-A1 on cell proliferation, and flow cytometry was conducted to analyze its effect on cell cycles and apoptosis. A scratch assay and a Transwell chamber were used to detect changes in cell migration and invasion. From the results, compared with the Annexin-A1 expression rate of 59.3% in para-carcinoma tissues, the expression of Annexin-A1 in cancer was reduced to only 32.6% in ESCC cells. Annexin-A1 was strongly expressed in highly differentiated ESCC cells without lymphatic metastasis and highly expressed in the CE81T-0 cell group with low metastasis. Annexin-A1 gene silencing promoted cell proliferation and inhibited apoptosis, blocked cells in the S-phase, and increased cell migration, leading to an increase in the number of invaded cells. Above all, Annexin-A1 could reflect the differentiation degree and lymph node metastasis of ESCC cells to some extent and was involved in the invasion, metastasis, proliferation, and other biological behaviors of ESCC cells, indicating an experimental basis for Annexin-A1 as a molecular marker in the early diagnosis of ESCC and the prediction of cell metastasis, invasion, and differentiation degree.
