Description

Etoposide (VP-16-213) is a chemotherapeutic topoisomerase II inhibitor that stabilizes the enzyme-DNA complex, blocking DNA replication (IC50=60.3 µM). It is widely used in cancer research to study mechanisms of apoptosis and autophagy in both cellular and animal models of various malignancies.

In Vivo	METHODS: To detect anti-tumor activity in vivo, Etoposide (10 mg/kg) and Cisplatin (5-7.5 mg/kg) were intraperitoneally injected every two days for two weeks into KSN nude mice harboring human endometrial adenocarcinoma tumors Ishikawa. RESULTS: Etoposide, as a single agent, had little or no inhibitory effect on tumor growth, while the combination of Etoposide and Cisplatin significantly inhibited tumor growth. METHODS: To detect anti-tumor activity in vivo, Etoposide (80 mg/kg in 0.5% methylcellulose) was administered by gavage to immunodeficient mice harboring human glioblastoma tumor U87 once a day for 40 days. RESULTS: 80 mg/kg Etoposide inhibited U87 tumor growth by 95%. Read more...
In Vitro	METHODS: Human cervical cancer cells HeLa were treated with Etoposide (25-400 μM) for 24-48 h, and cell viability was measured by MTT. RESULTS: Etoposide inhibited the proliferation of Hela cells with IC50s of 167.3 μM and 52.7 μM for 24 h and 48 h, respectively. The IC50 of Etoposide was 167.3 μM and 52.7 μM at 24 h and 48 h, respectively. METHODS: Human lung adenocarcinoma cells A549 were treated with Etoposide (0.75-3 μM) for 4 h. The cell cycle was detected by Flow Cytometry. RESULTS: Etoposide caused a significant decrease in the percentage of A549 cells in G0/G1 and S phases. Meanwhile, the percentage of A549 cells in G2/M phase was significantly increased. METHODS: Mouse embryonic fibroblast MEFs were treated with Etoposide (1.5-150 μM) for 3-18 h, and the expression levels of target proteins were detected by Western Blot. RESULTS: 150 μM Etoposide induced a strong cleavage of caspase-3 within 6 h, while 1.5 or 15 μM activated caspase-3 only after 18 h. Read more...
Cell Research	After the Etoposide treatment, cells are removed from the dish with phosphate-buffered saline (PBS) containing 0.03% trypsin and 0.27 mM ethylenediaminetetraacetic acid (EDTA) and are diluted into culture dishes in appropriate numbers to yield between 20 and 200 colonies. After 12 days, cultures are fixed with methanol-acetic acid, stained with crystal violet, and scored for colonies containing more than 50 cells . Read more...
Animal Research	The in vivo model for nude mice HB (NMHB) has been established. Only HB cells with embryonal components are grafted and reproduced successfully in this model. Each NMHB subsequently is transplanted into 50 mice for treatment groups. Treatment is initiated when the majority of the tumors reach a volume of 50-100 mm3. The mice are stratified according to their tumor volume and randomly assigned to groups of ten animals each. The animals injected with tumor are given ifosfamide, cisplatin, doxorubicin, etoposide (10 mg/kg/day, i.v.), and carboplatin as single agents in two blocks. One group of ten animals for each original xenograft served as a control group. After initiation of treatment, the tumor growth is recorded at 5-day intervals for 25-30 days and the relative tumor volumes are calculated. Twenty-four hours before the animals are sacrificed, bromodeoxyuridine (BrdU) is injected intraperitoneally for the semiquantitative determination of proliferation activity of the tumor cells (50 μg of BrdU/g body weight) .
