Overexpression of TAZ in the immortalized prostate epithelial cells promotes EMT, cell migration, and anchorage-independent growth.
A, the representative phase-contrast images and rhodamine-conjugated phalloidin staining images of vector control RWPE1 cells, TAZS89A overexpressing RWPE1 cells, and TAZS89A-S51A overexpressing RWPE1 cells were shown. B, Transwell assay of the vector control, TAZS89A, and TAZS89A-S51A RWPE1 cells. Representative images of the Transwell migration assays were shown. Relative migration ability was normalized to the vector control group. *, p < 0.05 by the Student's t test. C, soft agar assay of the vector control, TAZS89A, and TAZS89A-S51A RWPE1 cells. Representative images of soft agar colonies were shown. Clone numbers of each well were counted. *, p < 0.05 by the Student's t test. D, Western blotting analysis of the EMT markers (FN1, N-cadherin, vimentin, β-catenin, and E-cadherin) in the vector control, TAZS89A, and TAZS89A-S51A RWPE1 cells were shown. Quantitative analysis of Western blotting was indicated. Error bars, standard deviation.
