A recent study by Zhao et al. [100] identified 14 differentially expressed MRPs (MRPS17, MRPS21, MRPS23, MRPL9, DAP3, MRPL13, MRPL14, MRPL15, MRPL16, MRPL17, MRPL21, MRPL24, MRPL47, and MRPL55) in HCC from TCGA, all of which exhibited a good diagnostic performance. The gene discussed is MRPL21; the disease is hepatocellular carcinoma.
