Figure 14. Validation of abnormal expression of 3 modeled genes in OSCC. (A, B) Higher relative mRNA expression levels of IBSP and RDM1 detected by QRT-PCR in OSCC tissues. (C) Lower relative mRNA expression levels of RBP4 detected by QRT-PCR in OSCC tissues. (D, E) Higher relative mRNA expression levels of IBSP and RDM1 detected by QRT-PCR in cal27 and scc9. (F) Lower relative mRNA expression levels of RBP4 detected by QRT-PCR in cal27 and scc9. (G, H) IHC images reflecting the expression of RDM1 and RBP4 proteins in normal oral tissues and head and neck squamous cell carcinoma tissues. *p < 0.05; **p < 0.01; ***p < 0.001.
