Vasive), and MDA-MB-231 (TNBC, very metastatic) have been cultured in DMEM medium with ten fetal bovine serum and 1 antibiotics. Rat normal intestinal epithelial cells (RIEs) have been also cultured in the similar condition as above. GBL-60 cells (kindly provided by Dr. Sun Ha Paek at Seoul National University Hospital, Seoul, Republic of Korea) isolated from the brain of a patient who suffered from brain-metastasized breast cancer had been also cultured in DMEM, which was authorized by an Institutional Review Board at the Seoul National University Hospital [31]. 2.2. Cell Viability Assay and Flow Cytometry. Cells have been seeded on 96-well plates and treated with unique herbal extracts for 24 hours to 72 hours. Cell viability was measured by MTT assays. Absorbance was read at 570 nm on the ELISA reader (Molecular Devices, Palo Alto, CA, USA). Cells have been seeded in 6-well plates and treated with each extract for 24 hours. Cells had been then harvested and stained with propidium iodide (PI, 50 gmL) at space temperature within the dark. PI-positive cells were detected applying FACSCalibur (BD Biosciences, San Jose, CA, USA). two.three. Cell Migration, Invasion Assay, and Anchorage-Independent Assay. Cell migration was measured by scratching assays. Cells were seeded in 6-well plates after which scratched. 24 hours just after therapies with herbal extracts, migrated cell numbers were counted. For invasion assays, cells have been cultured inside the upper chambers precoated with matrigels and treated with each extract for 24 hours. Just after swapping the upper chamber meticulously, invaded cell numbers in 4 fields randomly chosen have been counted. For anchorage-independent assays, cells had been cultured on soft agar plates and treated with extracts each and every second day. At day 15, cells were stained with 0.five crystal violet to be visualized and colonies were counted with photomicroscope.Mediators of InflammationHerbal compositionAstragalus membranaceus Angelica gigas Trichosanthes Kirilowii MaximowiczAmount made use of (g) 333 333 333(a)Total amounts0.80 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 0.00 1.00 2.00 3.0.90 0.80 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 0.00 two.00 four.Formononetin4.5.6.7.eight.9.(AU)SH003 (min)6.00 eight.00 10.00 SH003 (min)Decursin(AU)12.14.0.50 0.45 0.40 0.35 0.30 0.25 0.20 0.15 0.ten 0.05 0.00 0.(AU)10.Nodakenin 20.(b)30.SH003 (min)40.50.Figure 1: HPLC profile of SH003.

ELISAs had been performed with human IL-6 ELISA kit (BD Biosciences,San Jose CA, USA) in line with the manufacturer’s instructions. 2.7. In Vivo Research. Animal research have been approved by Kyung Hee University Institutional Animal Care and Use Committee (KHU-IACUC). Six-week-old nude (NuNu) mice have been purchased from Oriental Science and injected s.c. with 1 106 MDA-MB-231 cells. When tumor volume reached 50 mm3 , mice have been randomly grouped and extracts were p.o. added everyday. Physique weights and tumor volumes have been measured 3 occasions a week. At the end of experiments, mice were sacrificed and all organs including tumors have been fixed with 4 formaldehyde. Blood was also taken in the heart and subjected to the blood test. Lung metastasis was measured by counting metastatic colony numbers on lungs. Fixed organs have been EP web embedded in paraffin and stainedwith hematoxylin and eosin f.
