Similarly, the screened 8 hub miRNAs and 24 of the 32 hub lncRNAs in the ceRNA network, including PCBP1-AS1, ITCH-IT1, GAS5, and MALAT1 have been confirmed to be involved in post-transcriptional regulation of breast cancer, liver cancer, colon cancer, bladder cancer, lung cancer, and other tumors. This evidence concerns the gene GAS5 and breast cancer.
