description | Although the treatment of liver cancer has made great progress, the mechanism of its occurrence is not completely clear. miR-155 plays an important regulatory role in tumorigenesis and development, including survival, proliferation, migration and invasion. However, the role and regulatory mechanism of miR-155 in liver cancer has rarely been reported. We analyzed miR-155 expression in liver cancer tissue samples and cell lines by qRT-PCR. The expression of miR-155 was measured by qRT-PCR before and after miR-155-mimic and sh-miR-155 transfection. CCK-8 and clonogenic assays were used to detect the proliferation of liver cancer cells. Cell scratch and invasion assays were used to detect migration and invasion. RNA-seq was used to detect the difference in RNA expression in liver cancer cells. SRPK1 expression was detected in liver cancer cells before and after transfection by qRT-PCR and western blotting. We observed that miR-155 was downregulated in liver cancer tissues compared with normal tissues. Furthermore, we demonstrated that liver cancer cell proliferation, migration and invasion are markedly suppressed by miR-155. Importantly, we also demonstrated that SRPK1 is directly regulated by miR-155 during the process of liver cancer cell proliferation and metastasis. Finally, the overexpression of miR-155 inhibits malignant biological behavior of human liver cancer cells. We report the abnormal expression of the miR-155 cluster in liver cancer cells, which inhibits cancer cell proliferation and metastasis. In addition, we identified SRPK1 as a target gene of miR-155 during the process of liver cancer cell proliferation and metastasis. |
