  • Effect of 103Pd Radioactive Stent on The Expression of Fas Gene and Its Relation with Apoptosis of Bile Duct Cancer Cells

    Objective To research the effect of γ-radiation released from 103Pd radioactive stent on the expression of Fas gene and its relation with apoptosis of bile duct cancer cells lines. Methods  The cancer cells of bile duct were dissociated into suspension in culture flasks, and the number of cells was counted by hemacytometry. The suspension was then stored in 2 ml freezing tubes in the density of 1×105/ml. They were set in two stents: general stent (general stent group) and 103Pd radioactive stent (103Pd stent group). The expression of Fas gene and apoptosis of bile duct cancer cells in general stent group and 103Pd stent group were analysed with immunohistochemistry technique and TUNEL method, respectively. Results  The expression level of Fas gene in 103Pd stent group was significantly higher than that in general stent group (P<0.05), and the number of apoptotic cancer cells in 103Pd stent group was also significantly more than that in general stent group (P<0.01). Conclusion There is a correlation between the expression of Fas gene and the apoptosis of bile duct cancer cells, which means that 103Pd radioactive stent may increase the expression of Fas gene and promote the apoptosis of cancer cells. It may be helpful for the further study of treatment for bile duct cancer using 103Pd radiative stent.
