Abstract

The invention belongs to the field of biotechnology, and particularly relates to a research method of application of wedelolactone to preparation of lung cancer treating products. The invention researches influence of the wedelelactone on the activity, the cycles and the apoptosis of non-small cell lung cancer A549 cells as well as intervention to p-Caspase3, p53, p-STAT1 and STAT1 gene expressionof the cells, explores the anti-tumor effect of the wedelolactone on the A549 cells and the mechanism thereof, provides the research method of the application of the wedelolactone to the preparationof the lung cancer treating products, and provides a theoretical basis for future research on the non-small cell lung cancer treating mechanism of the traditional Chinese medicine. The research methodcomprise the following steps: performing cell culture, detecting the cell proliferation inhibiting rate by a CCK-8 method, detecting the cycles and the apoptosis of the cells through propidium iodideand Annexin-PI staining and detecting gene transcription and translation of the cells through RT-PCR and Western blot.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a research method for the application of wedelia lactone in the preparation of products for treating lung cancer. Background technique [0002] Non-small cell lung cancer is the most common type of lung cancer, and currently ranks first in the mortality rate of malignant tumors in my country. Therefore, it is imminent to take active and effective measures to prevent and treat non-small cell lung cancer. In recent years, Western medicine is mainly used to treat non-small cell lung cancer clinically, and most western medicines are prone to strong dependence and serious side effects after long-term use. Therefore, the importance of research on the treatment of non-small cell lung cancer with traditional Chinese medicine has become increasingly prominent. [0003] Since wedelia lactone was first isolated and purified from Wedelia calendula in 1956, it has been regarded as a ...
