Next, IHC was further adopted to confirm the expression of Sox11 (yellow‐brown granules) in clinical tissue samples, revealing more pronounced Sox11 staining intensity in OLP‐associated OSCC tissue samples (OLP tissue develops into OSCC tissue, and OLP tissue is a precancerous lesion of OSCC tissue) relative to OLP tissue samples (Figures 1D and S1–S3). Here, SOX11 is linked to oral lichen planus.
