Research Progress on the Role of miRNA-448 in Tumor

MicroRNA (miRNA) is a class of endogenous non-coding and regulatory single stranded small RNA molecules, about 18 - 24 nucleotides in length. More than 800 miRNA coding genes have been identified in the human genome, and about 113 target genes are predicted to be regulated, which distinguishes it from most oligonucleotides and functional RNA degraded fragments. It is involved in the regulation of cell proliferation, differentiation, apoptosis and other cell activities. At the same time, it is abnormal in liver cancer, breast cancer, glioma and other tumors, becoming a new biomarker, and participating in cancer differentiation, invasion and metastasis through the interaction with multiple target genes, such as SATB1, NF-KB and 5-HT2B. Mir-448 is abnormally expressed in a variety of tumor cells, such as liver cancer and non-small cell lung cancer. mirNA-448 may play a very important role in tumors. In order to deepen the understanding of the role of mirNA-448 in tumors, this paper reviews the research progress of the role of mirNA-448 in tumors.
