The objective of the project for the reporting period was to generate a number prostate cancer cell lines that that are either myosin IC isoform A deficient or that constitutively express GFP-myosin IC isoform A. We used shRNA to generate isoform Anegative PC-3 cells and we generated a stable LNCaP cell line that expresses constitutively myosin IC isoform A-GFP. We are now in the process of analyzing the effect of these expression changes on secretion in these cell lines to determine the consequences of isoform A expression changes for the metastatic ability of prostate cancer cells. Using serial cloning of the 5 prime UTR of the human myosin IC gene we have identified a region that is involved in regulatory expression of myosin IC isoform A. We are now in the process of using ChIP assays to identifying the transcriptional elements that bind to this region and induce expression of myosin IC isoform A in prostate cancer cells.
