DGCR5 and hepatocellular carcinoma: In the study conducted by Dr. Sun and colleagues 44, using one RNA-sequencing dataset from TCGA and three datasets from GEO, they built a 9-lncRNA risk score system, and the expression level of DGCR9 was negatively associated with the 9-lncRNA risk score and positively correlated with OS of HBV-positive HCC patients.
