AB  - Molecular targeted cancer therapy is a promising treatment strategy. Considering the central role of the epidermal growth factor receptor in cell proliferation and survival, there are indications that targeted agents like tyrosine kinase inhibitors, i. e., erlotinib, may enhance the antitumor treatment by radiation. The aim of this study is to analyze the inactivation effects of gamma-rays and to test the radiosensitizing potential of erlotinib on human lung adenocarcinoma cells in vitro. Irradiations were performed with doses ranging from 1 Gy to 8 Gy. In order to increase the radiosensitivity of CRL-5876 lung adenocarcinoma cells, the cells were treated with a clinically relevant concentration of 2 mu M erlotinib. The effects of single and combined treatments were monitored using clonogenic survival, cell viability and proliferation assays at different time points. For the detection and visualization of the phosphorylated histone H2AX (gamma-H2AX), an important biological marker of DNA double-strand break formation, fluorescence inununocytochemistry, was performed. The response to the treatment was monitored at four time points: 30 min, 2, 6, and 24 h. Irradiations with gamma-rays resulted in significant cell inactivation regarding all analyzed biological endpoints. Combined treatments revealed consistent cell inactivation. Moreover, compared to gamma-rays alone, elevated levels of gamma-H2AX foci were observed after pretreatment with erlotinib, indicating radiosensitization through impaired DNA repair.

AB  - The effects of combined treatments with fotemustine and proton radiation on cell proliferation and induction of apoptosis have been analyzed in this study. HTB140 human melanoma cells were treated with fotemustine (100, 250 M) 24 h prior to irradiation (12, 16 Gy). The cells were irradiated in the middle of a therapeutic 62 MeV proton spread-out Bragg peak. An efficiency of applied treatments was observed throughout the evaluation of the cell proliferation 7 days after proton irradiation. The combined treatments with fotemustine and protons resulted in a greater antiproliferative response than each treatment alone. The number of apoptotic cells was estimated after 6 or 48 h using flow cytometry. The highest percentage of apoptotic cells was obtained 48 h after treatment with 250 M fotemustine and protons. Western blot analysis showed that induction of apoptosis was associated with p53 and Bax up regulation, and Bcl-2 down regulation. The induction of a caspase-3 activity and cleavage of PARP were clearly observed. These data indicate that a combined application of FM and proton irradiation is more effective in reducing melanoma cell proliferation and the induction of apoptosis, suggesting that FM can increase the radio-sensitivity of HTB140 melanoma cells.

AB  - Background: Considering that HTB140 melanoma cells have shown a poor response to either protons or alkylating agents, the effects of a combined use of these agents have been analysed. Methods: Cells were irradiated in the middle of the therapeutic 62 MeV proton spread out Bragg peak (SOBP). Irradiation doses were 12 or 16 Gy and are those frequently used in proton therapy. Four days after irradiation cells were treated with fotemustine (FM) or dacarbazine (DTIC). Drug concentrations were 100 and 250 mu M, values close to those that produce 50% of growth inhibition. Cell viability, proliferation, survival and cell cycle distribution were assessed 7 days after irradiation that corresponds to more than six doubling times of HTB140 cells. In this way incubation periods providing the best single effects of drugs (3 days) and protons (7 days) coincided at the same time. Results: Single proton irradiations have reduced the number of cells to similar to 50%. FM caused stronger cell inactivation due to its high toxicity, while the effectiveness of DTIC, that was important at short term, almost vanished with the incubation of 7 days. Cellular mechanisms triggered by proton irradiation differently influenced the final effects of combined treatments. Combination of protons and FM did not improve cell inactivation level achieved by single treatments. A low efficiency of the single DTIC treatment was overcome when DTIC was introduced following proton irradiation, giving better inhibitory effects with respect to the single treatments. Most of the analysed cells were in G1/S phase, viable, active and able to replicate DNA. Conclusion: The obtained results are the consequence of a high resistance of HTB140 melanoma cells to protons and/or drugs. The inactivation level of the HTB140 human melanoma cells after protons, FM or DTIC treatments was not enhanced by their combined application.

AB  - The correlation between time dependent viabilities, after applying two radiation qualities and two alkylating agents on HTB140 melanoma cells, has been studied. Irradiations were performed with gamma-rays and 62 MeV protons, close to the Bragg peak maximum, delivering doses of 8-24 Gy. Treatments with fotemustine (FM) and dacarbazine (DTIC) were carried out with concentrations of 0.05-2 mM. High radio-resistance of HTB140 cells revealed by a clonogenic assay was confirmed by microtetrasolium and sulforhodamine B, through the surviving fraction at 2 Gy (SF2), being 0.961-0.956 for gamma-rays and 0.931-0.887 for protons. A better efficiency of protons was illustrated by relative biological effectiveness at 2 Gy (RBE), ranging from 1.69 to 1.89. A kinetic study of concentration dependent cytotoxicity indicated that the best effect of the drugs, estimated as the concentration that produces 50% of growth inhibition (IC(50)), was obtained at 48 h, having values of 76 mu M for DTIC and 145 mu M for FM. The cytostatic ability of the drugs pointed out that the presence of DTIC at 24 h, compared to FM, was insufficient to produce an effect. Protons and FM demonstrated their pro apoptotic capacity. Cross-resistance between treatments applied to the HTB140 cells was observed, protons being the most efficient, while DTIC, FM and gamma-rays demonstrated a lower level of cell inactivation.

AB  - Viability of human HTB140 melanoma cells after being exposed to fotemustine (FM) and dacarbazine (DTIC) as well as to proton irradiation was studied. Effects of 100 and 250 mu M drugs were assessed after incubation of 6, 24, 48, 72, and 96 h. Irradiations were performed with 62 MeV therapeutic protons, delivering to the cell monolayer single doses of 2, 4, 8, 12, and 16 Gy. Viability was evaluated 7 days after irradiation. Inactivation level was estimated using microtetrasolium (MTT) and sulforhodamine B (SRB) assays. Combined effects of each drug and protons, were carried out using the same drug concentrations. Proton doses applied were those used in therapy, that is, 12 and 16 Gy. With the increase of drug concentration or irradiation dose, level of cell inactivation reached approximately 60%, 48 h after drug treatment or 7 days after irradiation at 16 Gy. Considering the rate of drug concentrations used, as well as the level of doses applied, it appears that HTB140 cells are more resistant to proton irradiation than to alkylating agents tested. The combined treatment with FM or DTIC and protons did not show significant changes of cell viability as compared to the effects of single agents. Since the time point for measuring cumulative effects of drug and irradiation was 48 h post irradiation, it seems that the obtained level of viability could be attributed primarily to the effects of drugs.

AB  - Malignant melanoma is a highly aggressive cancer with a poor prognosis due to resistance to radiotherapy and chemotherapy regimens. The mainstay of treatment remains DNA-alkylatingagent dacarbazine (DTIC). Fotemustine (FM), chloroethylnitrosourea agent, also has demonstrated significant antitumoral effects in malignantmelanoma. However, the resistance of melanoma cells limits their clinical application. In order to enhance the inhibition of melanoma cell growth, in this study, combined treatment of FM and DTIC with proton irradiation, was investigated. We analyzed the effects of combined treatment on HTB140 melanoma cell viability and proliferation. Significant inhibition of cell growth, especially cell proliferation, was obtained after treatment with protons and FM compare to single irradiation or drug treatment. Treatment with protons and DTIC has shown improved growth inhibition compare to appropriate single drug treatment, but not compare to irradiation as a single treatment.
