| MicroRNAs (miRNAs) are proposed as a family of short noncoding molecules able to
manage and control the expression of the gene targets at the posttranscriptional
level. They contribute in several fundamental physiological mechanisms as well as a
verity of human and animal diseases such as cancer progression. Among these tiny
RNAs, miR‐451 placed on chromosome 17 at 17q11.2 presents an essential role in
many biological processes in health condition and also in pathogenesis of different
diseases. Besides, it has been recently considered as a valuable biomarker for cancer
detection, prognosis and treatment. Therefore, this review will provide the critical
functions of miR‐451 on biological mechanisms including cell cycle and proliferation,
cell survival and apoptosis, differentiation and development as well as disease
initiation and progression such as tumor formation, migration, invasion, and
metastasis. |
