| Title |
Expression data for T24 bladder cancer cell line - scrambled, SOX4-KD and SOX4 overexpression |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by array
|
| Summary |
We knocked down SOX4 in T24 cell and created 3 cell lines: T24-scrambled, T24-SOX4-knockdown and T24-SOX4-rescue and compared gene expression changes
SOX4 is a developmental transcription factor that is overexpressed in as many as 23% of bladder cancer patients, but the role of SOX4 in bladder cancer tumorigenesis is not well understood. Given SOX4’s many roles in embryonic development and context-dependent regulation of gene expression, we sought to understand SOX4’s contribution to bladder cancer and to elucidate SOX4 regulated genes that might contribute to tumorigenesis. We employed a CRISPR interference (CRISPRi) method to transcriptionally repress SOX4 expression in T24 bladder cancer cell lines, rescued these cell lines with lentivirally expressed SOX4, and performed whole genome expression profiling. SOX4 knockdown cells exhibited decreased invasive capabilities but no changes in migration or proliferation, while rescue with SOX4 lentiviral vector restored the invasive phenotype. Gene expression profiling revealed 173 high confidence SOX4 regulated genes

| Overall design |
We created scrambled sgRNAk SOX4-sgRNA and transduced T24 bladder cell lines stably expressing Krab-dCas9-mCherry. We then stably re-expressed SOX4 into the T24-SOX4-sgRNA cells using a YFP-HA-SOX4 lentiviral vector
