|Squamous cell carcinoma (SCC) makes up more than 90% of cancer affecting the oral cavity including the oral tongue, buccal mucosa, floor of mouth, retromolar trigone, hard palate, alveolus and the lip. Treatment of oral cavity SCC (OCSCC) typically involves surgical resection, often followed by radiotherapy, and sometimes biologic agents. Despite this radical treatment, the 5-year survival rate for SCC affecting most oral cavity subsites has remained at 50% for the past 4 decades. Cancer stem cells (CSCs) have been identified in many types of cancers including OCSCC. Our recent data demonstrates the presence of 3 different putative CSC subpopulations within SCC of the oral tongue, buccal mucosa and lip. We have also demonstrated these CSC subpopulations express components of the renin-angiotensin system (RAS). We ahve also shown that the CSCs in one of these cancers studied (oral tongue SCC) also express the protease cathepsins B, D and G (CathG), suggesting the existence of potential bypass loops for the RAS. Our work suggests CSCs as a novel therapeutic target by modulation of the RAS using existing medications.|
