Although our analysis compared OSCC to BC samples, 19 significant genes overlapped with Farah and Fox’s 47 differentially expressed genes (DEGs), including the upregulation of ODC1 and LCN2 and the downregulation of COL1A1, COL11A1, and STAC2 in dysplastic leukoplakia samples (Supplemental File S1) [29]. Here, COL1A1 is linked to breast cancer.
