To further screen out the desired lncRNAs, we utilized RT-qPCR assay to identify the top 5 lncRNAs (PCAT7, FAM83C-AS1, LINC00144, HMGB3P1 and AC016735.1) that were remarkably upregulated in CRC tissues as compared to corresponding non-tumor tissues (Figure 1A). The gene discussed is HMGB3P1; the disease is neoplasm.
