Figure 1. Exaggerated SLC20A1 expression levels in HNSCC. (A, B) SLC20A1 mRNA expression between the HNSCC specimens and nearby sound tissues from TCGA database and qRT-PCR analysis. (C) SLC20A1 protein expression in the HNSCC specimens and nearby sound ones from Western blotting analysis. (D) DNA methylation modification associated with SLC20A1 expression in HNSCC. *, P<0.05.
