It is presumed that PROX-1 has both tumour-suppressive and oncogenic effects. The main aim of this study is to evaluate the role of PROX-1 and FOXC2 in the invasion and progression of OSCC cases and to correlate their expression with various histopathological parameters.</p><p><strong>Materials and methods: </strong>A prospective cohort study was conducted in a total sample size of 52 OSCC tissues and histologically tumour-free margins of 20. mRNA expression and protein levels of FOXC2 and PROX-1 were evaluated using real-time PCR and sandwich enzyme-linked immunosorbent assay techniques. Chi-square analysis and correlation analysis were done.
