| Title |
HepG2 |
| Sample type |
RNA |
| |
|
| Source name |
G2
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: HepG2
treatment: DMSO control
|
| Treatment protocol |
Before harvesting, HepG2 cells were incubated 6h with 10μM of NEN, 10μM of niclosamide, DMSO control. Treatment was initiated within one week after transplantation of the Patient Derived Xenograft (PDX). For each PDX model, tumor-bearing mice with similar initial bioluminescence signals were allocated into three groups (n=5 each), to be given daily: 1) NEN (200 mg/kg) mixed in autoclaved food, or 2) regular food, for six weeks. Tumor cells were harvested for the microarray experiment.
|
| Growth protocol |
HepG2 cells were seeded at 20% confluency, and grown 72h in Eagle’s MEM containing 10% FBS, penicillin and streptomycin at 37ºC and 5% CO2. To build PDX models, HCC tissues were collected from HCC patients who had undergone liver resection as part of their treatment. Single tumor cells labeled with luciferase gene were suspended in BEME medium containing 50% Matrix Matrigel, and then subcutaneously injected into 4–8 week old male NSG mice (20-25 g body weight). Tumor development was monitored daily. Once the subcutaneous xenograft reached 1 cm in diameter, it was removed and cut into 2 mm pieces and surgically implanted into the left lobe of the liver of another group of 6 weeks old NSG mice. Tumor growth was monitored once a week using the Xenogen IVIS in vivo imaging system (Caliper Life Sciences, Hopkinton, CA).
