Gene expression of Prox1 and FOXC2 by qRT-PCR.

<p>The mRNA expression levels of Prox1 (P<0.01) and FOXC2 (P<0.01) in OSCCs were higher than normal oral mucosa. Prox1 expression was upregulated in nodal metastasis positive OSCCs than in those with negative OSCCs (P<0.01). GAPDH was used for internal control. Error bar, standard deviation (S.D.).
