A PIK3CA transgenic mouse model with chemical carcinogen exposure mimics human oral tongue tumorigenesis

Summary Oral cancer causes significant global mortality and has a five‐year survival rate of around 64%. Poor prognosis results from late‐stage diagnosis, highlighting an important need to develop better approaches to detect oral premalignant lesions (OPLs) and identify which OPLs are at highest risk of progression to oral squamous cell carcinoma (OSCC). An appropriate animal model that reflects the genetic, histologic, immunologic, molecular...
