Embodiment

[0016] To detect the effect of arsenic trioxide on the proliferation, cycle and apoptosis of gastrointestinal stromal tumor cells. Divided into: arsenic trioxide group, negative control group. CCK-8 method was used to detect the effect of medication on cell proliferation in each group, arsenic trioxide group (μg / mL): 0, 0.1, 1, 2, 4, 8, and it was found that the inhibition rate of arsenic trioxide was close to 50% at a concentration of 2ug / mL. The effect of drugs on cell cycle and apoptosis was detected by flow cytometry AnnexinV-FITC / PI double staining technique, arsenic trioxide group: 2ug / mL. The protein extracted from the two groups of cells after drug treatment was detected by Western blot method to detect the expression changes of cell proliferation transcription-related proteins in Imatinib-resistant GIST cells before and after drug treatment. Nude mice of BALB / C / nu / nu strain, aged 3 to 4 weeks, with a body weight of 19.0 ± 2.0 g. Gastrointestinal stromal tumor dru...

Abstract

The invention discloses an application of arsenic trioxide to treatment of gastrointestinal stromal tumor. The arsenic trioxide is used for preparing an arsenic trioxide-containing drug for treating imatinib-resistant gastrointestinal stromal tumor, and can improve the sensitivity of gastrointestinal stromal tumor to imatinib and promote cancer cell apoptosis by inhibiting cell proliferation related PI3K / AKT / mTOR pathways. The arsenic trioxide can overcome the drug resistance of the gastrointestinal stromal tumor to the imatinib, and has good hygienic and economic effects.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a new application of a classic drug, arsenic trioxide, which is an application to the unsolved problem of drug resistance of gastrointestinal stromal tumors, and greatly relieves the economic burden of patients. Background technique [0002] Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract. The initial curative effect of imatinib targeted therapy is remarkable. However, after an average of 24 months of treatment, drug resistance will develop, which will greatly affect the prognosis of patients. Therefore, Secondary resistance to imatinib is a major clinical difficulty. Arsenic trioxide, or arsenic, is a classic of using poison as medicine. It has achieved outstanding curative effect in the treatment of acute promyelocytic leukemia, and can induce cell apoptosis. At present, there is no relevant research on the use of arsenic trioxide in...
