- Effect of Flavopiridol on Radiation-induced Apoptosis of Human Laryngeal and Lung Cancer Cells
- Suzy Kim, Eun Kyung Kwon, Seung Hee Lee, Hye Jin Park, Hong Gyun Wu
-
Radiat Oncol J. 2007;25(4):227-232.
-
|
PURPOSE: To investigate the flavopiridol effect on radiation-induced apoptosis and expression of apoptosis- related genes of human laryngeal and lung cancer cells.
MATERIALS AND METHODS: A human laryngeal cancer cell line, AMC-HN3 and a human lung cancer cell line, NCI-H460, were used in the study. The cells were divided into four groups according to the type of treatment: 1) control groups;... |

-
Radiat Oncol J. 2007;25(4):233-241.
-
|
PURPOSE: We examined the effect of the dual EGFR/HER2 tyrosine kinase inhibitor, GW572016, on EGFR/HER2 receptor phosphorylation, inhibition of downstream signaling and radiosensitization in either an EGFR or HER2 overexpressing human breast cancer xenograft.
MATERIALS AND METHODS: We established SCID mice xenografts from 4 human breast cancer cell line that overexpressed EGFR or HER 2 (SUM 102, SUM 149, SUM 185,... |

Radiat Oncol J. 2007;25(4):242-248.
-
|
PURPOSE: To study the effect of recombinant human epidermal growth factor (rhEGF) on oral mucositis induced by cisplatin and radiotherapy in a mouse model.
MATERIALS AND METHODS: Twenty-four ICR mice were divided into three groups? the normal control group, the no rhEGF group (treatment with cisplatin and radiation) and the rhEGF group (treatment with cisplatin, radiation and rhEGF). A model of... |

Radiat Oncol J. 2007;25(4):278-282.
-
|
Diffuse pigmented villonodular synovitis (PVNS) is an uncommon aggressive synovial proliferative disorder of unknown etiology affecting the joint linings. Though a histologically benign inflammatory process, because of its aggressive growth with bone destruction or recurrence, it is frequently suggested to occur as a low malignant neoplasm.
Optimal treatment is surgery, but the local recurrence rate after radical synovectomy for diffuse PVNS... |
