Methods: Patients with advanced bladder cancer who accepted bladder infusion chemotherapy in Wuhan Red Cross Hospital between March 2015 and August 2016 were selected and randomly divided into the IFN-α+GEM group and the GEM group who acceptedα-interferon + gemcitabine combined with infusion chemotherapy and single gemcitabine infusion chemotherapy respectively. The contents of bladder cancer markers, cancer cell apoptosis molecules and angiogenesis molecules in urine were detected before treatment and 3 months after treatment. Results: 3 months after treatment, NMP-22, BLCA-4, Apo-A1, HA, CYFRA21-1, ANG, NAC-1, VEGF and bFGF levels in urine of both groups of patients were significantly lower than those before treatment while PTEN, TRAIL, Bim, HSG and p16 levels were significantly higher than those before treatment, and NMP-22, BLCA-4, Apo-A1, HA, CYFRA21-1, ANG, NAC-1, VEGF and bFGF levels in urine of IFN-α+GEM group were significantly lower than those of GEM group while PTEN, TRAIL, Bim, HSG and p16 levels were significantly higher than those of GEM group. Conclusion: α-interferon + gemcitabine combined with infusion chemotherapy can be more effective than single gemcitabine infusion chemotherapy in killing cancer cells and inhibiting the proliferation and infiltrative growth of the cancer cells.展开更多

Methods The expressions of Caspase 8 mRNA and protein were detected with RT-PCR and Western blot analysis. The effects of IFNγ, TRAIL, IFNγ ＋ TRAIL, IFNγ ＋ Caspase 8 inhibitor ＋ TRAIL, IFNγ ＋ cisplatin ＋ TRAIL, and IFNγ ＋ etoposide ＋ TRAIL on the growth and apoptosis of SH-SY5Y cells were detected with the methods of MTT and flow cytometry. The relative Caspase 8 activity was measured with colorimetric assay. Results Caspase 8 was undetectable in SH-SY5Y cells but an increased expression of Caspase 8 mRNA and protein was found after treatment with IFNγ. SH-SY5Y ceils themselves were not sensitive to TRAIL, but those expressing Caspase 8 after treatment with IFNγ were. The killing effect of TRAIL on SH-SY5Y cells expressing Caspase 8 was depressed by Caspase 8 inhibitor. Cisplatin and etoposide could enhance the sensitivity of TRAIL on SH-SY5Y cells. The relative Caspase 8 activity of SH-SY5Y cells in IFNγ ＋ TRAIL group was significantly higher than those of control group, IFNγ group, TRAIL group, and inhibitor group （ P 〈 0. 01 ）. There was no significant difference among IFNγ ＋ TRAIL group, IFNγ ＋ cisplatin ＋ TRAIL group, and IFNγ ＋ etoposide ＋ TRAIL group. Conclusions IFNγ could sensitize SH-SY5Y cells to TRAIL-induced apoptosis and this may be realized by the up-regulation of Caspase 8. Cisplatin and etoposide could enhance the killing effect of TRAIL on SH-SY5Y cells.展开更多
