FCGR3A and neoplasm: Furthermore, to identify tumor cell types that predominantly express FCGR3A, we analyzed FCGR3A gene expression levels in pan-cancer single cell lines using the GDSC database (Supplementary Figure S1A) and the CancerSCEM website (Supplementary Figure S1B), and the results showed that FCGR3A was highly expressed in most tumor cell lines.
