Delay siege The growth of prostate tumors, reduces the production of PSA and zinc Gert the progression of CRPC in the LNCaP xenograft model. This activity Makes t trilogy fight against cancer in vivo, clinical admission and no side effects carbidopa an interesting tool for use in combination with a drug already on the treatment of prostate cancer, including normal bicalutamide. Bicalutamide is currently a Man Ver standard second-line hormonal prostate cancer after the failure of castration. However, the answer to which, after the failure of castration bicalutamide, even at high doses is not sustainable and Behandlungsm opportunities Descr are at this stage Nkt. This obstacle k Nnte by the addition of new agents, such as abiraterone, MDV3100 or carbidopa be bypassed. Another advantage is the required dose of bicalutamide to achieve a therapeutic effect by combination with carbidopa are reduced. The objectives of this study was whether carbidopa in synergy with bicalutamide in inhibiting Lebensf Ability of the cells and AR transcriptional activity t in the cells of the APC test. In this context, we investigated whether pharmacological orientation of the AR-axis by the combined treatment of bicalutamide and carbidopa significantly improved antitumor activity t in vivo CRPC LNCaP xenograft compared with the one-way for each drug. The translational approach of this study, the efficacy t is set by the use of carbidopa and Bicalutamide for future treatment of patients with CRPC. METHODS Prostate Cancer Cell Lines andrea gents The human prostate cancer cell lines LNCaP and C4-2 were used in this study kindly fgfr provided by Dr. Leland WK Chung
available and tested and certified by the whole genome and transcriptome sequences Age on all Illumina Genome Analyzer IIx platform in July 2009. After the resurrection, the two cell lines were placed within the last 3 months. LNCaP and C4 2 cells were grown in RPMI 1640, erg complements Held with 5% activated carbon removes serum or 5% serum f Cultured fetal bovine serum atmosphere re and without antibiotics at 378C in 5% CO second Anti-PSA antibody Body was from Santa Cruz Biotechnology, and the fight against vinculin Antique Body from Sigma Aldrich. For Ki-67 detection, we used the RM 9106 Antique Rpers from Lab Vision. The treatment of prostate LNCaP and C4 Cancer Cells With carbidopa andBicalutamide 2 cells were plated at a density of 2.5 and 1.25 104/cm2 and 104/cm2, and treated a day later Ter with carbidopa, bicalutamide, or the combination of both. Carbidopa was purchased from Sigma Aldrich and bicalutamide was purchased kindly provided by Astra Zeneca available. For use in vitro, carbidopa was dissolved in dimethyl sulfoxide St and at 208C, w During bicalutamide in DMSO gel St and 4 weeks of storage at room temperature. Based on previous results from our group has used carbidopa at a fixed concentration of 50 mM in vitro, au It for testing synergy. For the in vivo studiescarbidopa dissolved in pure DMSO St and every day before treatment to 10% DMSO in PBS and injected with 50 mg / kg Body weight, w During bicalutamide diluted with H2O and used 50 mg / kg K body weight. The ability Lebensf Of the cells was determined using the test CellViabilityAssays crystal violet, as described above. The cells were plated in 12-well plates and with carbidopa, bicalutamide, or a combination of both, as described above in media erg Complements CSS 0.1 nM R1881 described. Kristallviolettf Staining was Carri.
