Moreover, the relative expression of LINC00963 was consistently increased in sphere cells (Figure 2C), CD44+ (Figure 2D), and ALDH1+ (Figure 2E) cells derived from two types of OSCC cell lines (SAS and GNM), suggesting that LINC00963 was also elevated in CSCs and may be associated with the cancer aggressiveness. This evidence concerns the gene ALDH1A1 and cancer.
