The rate of high ELOVL6 expression was 45.5% in the OSCC II/III group and 16.7%, 5.4%, and 18.4% in the normal, dysplasia, and OSCC I groups, respectively, and the rate of high ELOVL6 expression in the OSCC II/III group was significantly higher than that in the other three groups (Table 3; Figure 7). Here, ELOVL6 is linked to dysplasia.
