This miRNA sequence was predicted based on homology to a verified miRNA from mouse [1]. Michael et al. subsequently verified expression of miR-145 in human, and demonstrated significantly reduced levels of the miRNA in precancerous and neoplastic colorectal tissue [2]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
