PTGDR and hepatocellular carcinoma: They also identified several miRNA-SNHG1 subnetworks (such as hsa-miR-195-5p-SNHG1, hsa-miR-497-5p-SNHG1, and hsa-miR-101-3p-SNHG1) and several mRNA-SNHG1 pairs (such as MYLK-AS1-SNHG1, CHEK1-SNHG1, and KIF2C-SNHG1) in the ceRNA regulatory network of HCC [33, 34].
