Further, we used the UALCAN (http://UALCAN.path.uab.edu/) database to assess the protein expression of CD300A in a number of solid cancers, such as breast cancer (BRCA), GBM, LUAD, KIRC, and ovarian cancer (OV) (except for CD300LF in GBM, other CD300 members were not identified in these proteomic datasets). This evidence concerns the gene CD300A and ovarian cancer.
