For instance, by integrative analysis of the Gene Expression Omnibus (GEO) database and TCGA database, Zhang et al. elaborated that UCA1, HOTTIP, and HMGA1P4 lncRNAs were upregulated in GC tissues and firstly identified that HMGA1P4, a target of miR-301b/miR-508, took part in the process of cell cycle and senescence by modulating CCNA2 in GC. The gene discussed is HOTTIP; the disease is gastric cancer.
