Fig 1: MYL1, ACTN2 and LAT expression validation. (a) Protein expression levels in HNSCC as compared to those in normal tissues by IHC staining from the Human Protein Atlas database. Black square boxes represent typical normal and HNSCC tissues, respectively. (b) Comparison of gene expression level by using qPCR. (c) IHC staining of the proteins in OSCC tissues and normal oral mucosa tissues. Scale bars represent 100 µm. *: P < 0.05; **: P < 0.01; ***: P < 0.001; ****: P < 0.0001.
