Smad4 and pancreatic cancer

WebbResults: Today, the concept that progression of epithelial precursor lesions leads to invasive PDAC as a result of accumulating mutation in K-ras, p16INK4A, p53 and Smad4 is widely accepted. Multiple signaling pathways that PDAC utilizes to acquire its tumorigenic features have been identified.
