Cancer refers to a group of cells that are caused by continuous division and proliferation of abnormal cells by destroying the balance of cell division and death by various causes, and are sometimes referred to as tumors. It usually occurs in more than 100 different parts of the body, including lungs, lymph nodes, bones, and white blood cells, and has a high mortality rate due to metastasis to the surrounding tissues.

[Example]
1. Materials and Methods
1-1. reagent
Sinensetin was purchased from MedChem Express (MCE, USA) and stocked with DMSO at 10 mM. Dulbecco's Modified Eagles medium (DMEM) used for cell culture was purchased from Hyclone (Logan, UT), and Bronchial Epithelial Cell Growth Medium (BEGM ™ ) Bulletkit ™ was purchased from Lonza (Switzerland). Penicillin / streptomycin and fetal bovine serum (FBS) added to the medium were purchased from Gibco (Grand Island, NY). MTT (3- [4,5-dimethylthiazol-2-yl] -2,5-diphenyltetrazolium bromide) used for the measurement of apoptosis was purchased from Sigma-Aldrich (St. Louis, Mo.).
1-2. Cell culture and sample treatment
HepG2 cells, which are human liver-derived hepatic cancer cells, were cultured in DMEM medium. AGS cells derived from human cells were cultured in RPMI medium supplemented with 10% FBS and 1% penicillin / streptomycin. And cultured in a CO 2 incubator (5% CO 2 , 95% air) at 37 ° C. When the cells were over 80% in the culture dish, the cells were washed with phosphate buffered saline (PBS, pH 7.4) and subcultured with 0.25% trypsin-2.65 mM EDTA. Cynecetin was added to 10 mM of DMSO and treated with 50 μM and 100 μM of HepG2 cells. AGS cells were treated with 40 μM and 50 μM of cinnenecetin with 0.1 μM and 0.2 μM of cisplatin, and the same amount of DMSO was added to the control.
1-3. Measurement of cytotoxicity (MTT assay)
HepG2 and AGS cells were plated in 48-well plates at 5 × 10 4 and incubated for 16 h at 37 ° C in a 5% CO 2 incubator. After the medium was removed, each of the following samples was treated according to the concentration, and the control group was treated with dimethyl sulfoxide (DMSO). Each sample was treated with 50 μl of MTT (0.05 g / 10 ml; 0.5%) solution (final 0.05% MTT) for 48 hours for HepG2 and for 24 hours for AGS. The cells were reacted for 3 hours in a 5% CO 2 incubator at 37 ° C to reduce MTT. All wells were removed and 500 ul of DMSO was added to each well. The absorbance was measured at 560 nm using an ELISA reader.
1-4. Migration assay
HepG2 and AGS cells were plated at 2 × 10 5 in a 12-well plate for cell culture and cultured for 16 hours. The cells were scrunched using a plastic 200ul tip and washed with PBS. After that, the drug was treated at each concentration, and the cells were reacted in CO 2 incubator for each hour. The cell mobility was photographed and the area was measured using the Image J program.
1-5. Cell death (Annexin V measurement)
HepG2 and AGS cells were plated at 5 × 10 5 in a 6-well plate and treated with each concentration 16 hours later. After the reaction time of the drug has elapsed, cells were washed once with PBS and cells were collected using typsin-EDTA. Cells were stained with FITC Annexin V Apoptosis Detection Kit I (BD Biosciences, San Jose, Calif.) By flow cytometry using FACS Calibur (BD Biosciences).
1-6. Cell cycle analysis (PI staining)
HepG2 and AGS cells were plated in 6 well plates and flow cytometry was used. HepG2 and AGS cells were collected after each reaction time, and cells were fixed at -20 ℃ for 1 hour with 70% ethanol. The cells were washed with PBS and reacted with 1 U / ml of RNase A (DNase free) and PBS at 37 ° C for 1 hour, then 5 ug / ml of propidium iodide (PI) And then reacted. 10,000 cells per sample were measured using a FACS Calibur (BD Biosciences, San Jose, Calif.).
1-7. Protein expression experiments (Western blot analysis)
HepG2 cells treated with cinnenecetin were washed with PBS and incubated with RIPA lysis buffer (50 mM Tris-HCl pH 7.4, 1% NP-40, 0.25% Na-deoxycholate , 150 mM NaCl, 1 mM EDTA) was added to extract whole proteins of the cells. Bicinchoninate (BCA) assay was used to quantitate the protein concentration, electrophoresed on SDS-polyacrylamide gel, and then transferred to the PVDF membrane. To prevent the binding of nonspecific antibodies to membranes, the cells were incubated in 5% skim milk for 1 hour. After incubation at 4 ° C with primary antibody, horse radish peroxidase (HRP) conjugated secondary antibody was reacted. The antibodies were reacted with ECL kit (Promega, USA) and then measured using Chemidoc instrument (Bio Rad, California, USA).
1-8. Statistical processing
All experimental results were repeated at least 3 times and the results were expressed as mean ± standard deviation. The statistical significance of each test result was determined by Student's t-test as compared to the control group without sample and statistically significant when the P value was less than 0.05.
2. Results
2-1. Induction of HepG2 cell death of cinnenecetin
One of the flavonoids, cinnexetin, was treated with time and concentration to determine the death of HepG2, a human liver cancer cell, and MTT assay was performed. HepG2, a human liver cancer cell, showed apoptosis in a time - and concentration - dependent manner in groups treated with 24 hours and 48 hours of cinnenecetine. When compared with the control group, the cancer cell killing activity was confirmed to be about 50% at 50 μM and 65% at 100 μM in the group treated with cinnensetin for 48 hours. In addition, in order to confirm whether it affects extrahepatic extra-cellular cells, the human normal hepatocyte, Thle2 cells, was also treated with cinnenecetin. As a result, it was confirmed that cinnenecetin had a greater effect on liver cancer cells than hepatic normal cells in the group treated for 24 hours and 48 hours (see FIG. 1).
2-2. Effect of Cynenecetin on Cell Death in Gastric Cancer Cells
To determine whether AGS cells die in human gastric cancer cells, various concentrations of cinnenecetin were treated for 24 hours and then assayed by MTT assay. Cynenecetin showed AGS cell killing activity in a concentration dependent manner. When compared to the control group treated with DMSO, the cytotoxic effect was about 25% at 60 μM of cynesecetin and 35% at 80 μM (see FIG. 2). In addition, the cytotoxic effect of cisplatin, which is known as an anticancer drug, was examined in AGS cells, and showed a killing effect of about 50% at 0.3 μM of cisplatin (see FIG. 3).
2-3. Increased cell killing effect by combination of cinnenecetin and cisplatin
AGS cells were treated with 40 μM and 50 μM of cinnenecetine and treated with 0.1 μM and 0.2 μM each cisplatin. When treated with 0.1 μM of cisplatin alone, cell viability was reduced to about 30% in the group treated with 50 μM of cinnenecetin, although the cell viability was about 90% (see FIG. 4). In addition, about 75% cell viability was observed in the group treated with 0.2 μM of cisplatin alone, but about 50% cell viability was shown when treated with 40 μM of cinnenecetin (see FIG. 4). Thus, when cisplatin and cinnenecetin are treated together, cisplatin exhibits a higher apoptotic action in AGS cells, which are human gastric cancer cells.
2-4. Identification of HepG2 and AGS cell migration effect of cinnenecetin
Cell migration assay (wound healing assay) was performed to investigate the effect of cinnenecetin on HepG2 cell mobility. When HepG2 was treated with 50 μM and 100 μM of Sinensetin for 48 h, the cell migration area was 50% at 50 μM and 30% at 100 μM, compared with the control. As a result, it was confirmed that the mobility of the cells was inhibited by cinnenecetin in a concentration-dependent manner of HepG2 cells (see FIG. 5). In the case of AGS cells, cinnenecetin and cisplatin inhibited cell mobility compared to the control, respectively, but the combination of cinnenecetin and cisplatin showed greater mobility inhibition (see FIG. 6).
