Based on this point, we have sequentially identified tumor suppressive miRNAs and miRNA-mediated molecular targets contributing to cancer cell invasion and metastasis, such as miR-1 regulates TAGLN2, miR-145-FSCN1/LASP1, miR-133a-MSN and miR-138-VIM [9, 20, 31-33]. The gene discussed is MSN; the disease is cancer.
