Identifying key factors that regulate the transition from primary to metastatic cancer is a fundamental challenge. Walsh et al. took a systems biology approach integrating computational, in vitro, and in vivo experiments to identify TRIM25 (tripartite motif containing 25) as a key factor that regulates metastatic gene signatures both at the transcriptional and post-transcriptional level in breast cancer. Targeting TRIM25 therapeutically is attractive because it governs a broad set of coordinated transcriptional modules that dictate metastatic progression.
Keywords: TRIM25; breast cancer; metastasis; network inference; transcription.
