<b><i>Background:</i></b> MicroRNAs (miRNAs) represent a group of non-coding RNAs measuring 19–23 nucleotides in length and are recognized as powerful molecules that regulate gene expression in eukaryotic cells. miRNAs stimulate the post-transcriptional regulation of gene expression via direct or indirect mechanisms. <b><i>Summary:</i></b> miR-210 is highly upregulated in cells under hypoxia, thereby revealing its significance to cell endurance. Induction of this mRNA expression is an important feature of the cellular low-oxygen response and the most consistent and vigorous target of HIF. <b><i>Key Message:</i></b> miR-210 is involved in many cellular functions under the effect of HIF-1α, including the cell cycle, DNA repair, immunity and inflammation, angiogenesis, metabolism, and macrophage regulation. It also plays an important regulatory role in T-cell differentiation and stimulation.
