In EOLP group, only cytoplasmic cdk4 expression is significantly increased; compared to NOLP and normal mucosa (green invisible has a value of zero), similarly as in Figure 2.
EOLP = erosive oral lichen planus; NOLP = non-erosive oral lichen planus; OSCC = oral squamous cell carcinoma; cyt. = cytoplasmic; nuc. = nuclear.
