The absorbance of each well was found with an enzyme linked immunosorbent assay microplate reader at a wavelength of 570 nm, and then a growth inhibition rate was calculated. All experiments were repeated 3 times beneath the same conditions. 1. 7 Detection of cell apoptosis by flow cytometry Cells were treated with drugs as described in 1 and inoculated into a 25 mL flask. 5 order Cathepsin Inhibitor 1 when they covered 80% of the flask. . After being treated for 48 h, cells were collected by centrifuge, digested by trypsin, resuspended in a EP tube with PBS, and fixed in hands down the polymerisatum.. Before getting used in the test, the cells were washed three times in PBS, included Annexin V/PI saved in 4 C, stood at room temperature without light for 3 min, and were filtered in 300 mesh filter traps. Flow cytometry was used to Endosymbiotic theory analyze cell apoptosis. . 1. 8 Reverse transcribed quantitative PCR detection of IGF 1R, PDGFA, NGF, NF W, and JNK2 mRNA expression in primary breast cancer cells and breast cancer cell line MDA MB 231 Cells were inoculated in to four 75 mL flasks and cultured for 48 h in RPMI 1640 culture medium plus 10 % fetal bovine serum. After removing the first medium, cells were treated for 48 h with medications as described in 1. 5. Total RNA in most experimental groups was isolated with RNAiso Plus following instructions. The focus and purity of isolated total RNA was measured by ultraviolet spectrophotometry. As inner consults the cDNA was then reverse transcribed according to the instructions inside the reagent kit and amplified via PCR with w actin and glyceraldehyde 3 phosphate dehydrogenase. Primer style Decitabine price application Primer 5. . 0 from Shanghai Biotechnology was used to design the primer. A total of internal increased solution and 5 uL test factor were separately subjected to agarose gel electrophoresis and analyzed via the Gel Doc XR quantitative research system. As the ratio of increased integral gene absorption to central gene absorption cell term was represented. Detection of protein expression in IGF 1R and PDGFA via western blotting Cell protein products in each experimental group were collected by western cell lysate. The optical band concentration was analyzed and recorded using the Gel Analysis System. Detection of relative protein strength was displayed within the rate of the optical protein band concentration towards the central gene t actin. Recognition of protein expression in xenografted cyst tissue in nude mice by immunohistochemistry Xenografted tumors from sacrificed nude mice were obtained for immunohistochemical analysis. The look of brown granules within the cytoplasm was considered positive for protein. Stable proliferation was shown by the cultured breast carcinoma cells after two weeks by staying with the wall in long shuttle forms, although some interstitial cells showed in polygon stretching progress, sometimes the cell parts and dross covered there.
