Popis: | Purpose: To evaluate the efficiency of anti ErbB4 targeted therapy combined with irradiation (XRT) over each modality alone in prostate cancer. Methods: Clones with low and high expression of ErbB4 isolated by a limited dilution technique from an androgen independent Cl-1 cell line were used. The cells from these clones were exposed to XRT (single dose of 2-6 Gy) and to anti-ErbB4 monoclonal antibody (mAb). The XTT test was used to measure cell survival. In addition, tumor bearing nude mice were treated either by XRT, mAb or by a combined treatment. Tumor sizes were recorded at given time points. Results: Clones with high ErbB4 expression grew faster than those with low ErbB4 expression. XRT inhibited the growth of both expressive and non-expressive ErbB4 cells, while mAb inhibited only high ErbB4 expressing cells. The combination of XRT and mAb resulted in a 30% reduction of the survival of high ErbB4 expressing cells over XRT alone (p=0.013). In tumor bearing mice the tumor size in the combined arm was ... |
