Single cell data analysis and protein level of pFRGs. A Stacked violin plots illustrating expression levels of pFRGs in different cell clusters. B UMAP projections of the expression patterns of 6 highly expressed pFRGs between cell types. C Immunohistochemistry images showing the expression of optimal pFRGs in tumor and normal specimens. The protein expression levels are classified as high, low, and ND.
