Abstract 997: Three-dimensional high-throughput drug screening for bladder cancer

Recent progress in understanding the molecular mechanisms that underlie bladder cancer carcinogenesis offers the prospect of specifically targeting signaling pathways to achieve more effective and rational treatment. In a novel, 3-dimensional high-throughput drug screening (3D HTS) platform to identify novel agents affecting bladder cancer cells, 24 molecularly-targeted agents were screened in seven human bladder cancer cell lines (UCUM3, T24, SW780, RT4, J82, 5637 and 253J-BV). The efficacy of 24 targeted agents on the bladder cell lines varied dramatically on their genomic alterations. BEZ235 (mTOR and PI3K inhibitor) showed antitumor effect in most of cell lines except UMUC3. Another mTOR inhibitor, AZD2014 (inhibitors of mTORC1 and mTORC2) also had IC50 Note: This abstract was not presented at the meeting.
