In Vivo SILAC-Based Proteomics Reveals Phosphoproteome Changes during Mouse Skin Carcinogenesis
Abstract
SILAC technology in combination with high-resolution mass spectrometry (MS) can be successfully used to measure phosphoproteomes in vivo. Here, Zanivan, Mann, and colleagues have applied SILAC-based MS to investigate phosphoproteomic changes during skin carcinogenesis, using the DMBA/TPA two-stage mouse model. Using this approach, the authors have revealed the phosphoproteomic dynamics that accompany skin cancer progression and predict specific kinase activities associated with tumor malignancy.
