Abstract：To probe the effects of Trichinella spiralis muscle larval somatic proteins on small cell lung cancer H446 cells and the possible mechanism of anti-tumor,H446 cells were culture with 0.2 mg/mL, 0.4 mg/mL, 0.6 mg/mL, 0.8 mg/mL, 1.0 mg/mL, and 1.2 mg/mL somatic proteins respectively. The experimental group was set and no dosing as control group. MTT colorimetric assay was used to test the effects of T. spiralis muscle larval somatic proteins on the proliferative activity of H446 cells. We used flow cytometry (FCM) to test the influence of T. spiralis muscle larval somatic proteins induced H446 cells apoptosis.The real-time PCR and Western blot methods were used to detect the expression of Cyt-C and apoptotic protease activating factor 1(Apaf-1) mRNA and protein. The MTT colorimetric assay showed that T. spiralis muscle larval somatic proteins could inhibit the proliferation of H446 cells; the flow cytometry showed that polypide proteins acted on H446 cells after 24 h appeared an obvious effect on promoting apoptosis. Results of real-time PCR and Western blot analysis indicated that compared with the control group, Cyt-C and Apaf-1 showed up-regulated expression. T. spiralis muscle larval somatic proteins could inhibit proliferation activity and induce the apoptosis of H446 cells, and its effects may be related to up-regulated expression of Cyt-C and Apaf-1.
