 This study examined the expression of musin-4 and head and neck squamous cell carcinomas, HNSCCs. It was observed that musin-4 expression was significantly higher in tumor tissues compared to normal epithelial tissues. Additionally, there was a significant correlation between tumor grade and intensity of musin-4 expression. This suggests that musin may forth be involved in the progression of HNSCCs.
