We further explored the biological roles of linc01184 in CRC cell lines in vitro and confirmed its oncogenic mechanism that linc01184 may function as a ceRNA to sponge miR-331, subsequently upregulating the expression of its target HER2 and triggering off the activation of p-Akt/p-ERK1/2 signaling pathways at the posttranscriptional levels. The gene discussed is AKT1; the disease is colorectal carcinoma.
