PIMREG and head and neck squamous cell carcinoma: Our results showed that FAM64A was consistently overexpressed in HNSCC tissues compared to paired adjacent normal tissues (ANTs) (TCGA HNSCC, GSE127165, and GSE37991) (Fig. S1a–c) or normal control tissues (GSE55550, GSE23036, and GSE30784) (Fig. S1d–f).
