Furthermore, comparison with the Human Protein Atlas (www.proteinatlas.org) [27] revealed that high expression of genes such as ribosomal protein S2 (Rps2), Jupiter microtubule-associated homolog 2 (Jpt2), purine nucleoside phosphorylase (Pnp), and WD repeat domain 55 (Wdr55) was considered unfavorable for liver cancer prognosis, while high expression of glycine N-methyltransferase (Gnmt) was considered favorable. This evidence concerns the gene WDR55 and liver cancer.
