MicroRNAs (miRNAs) are small noncoding RNAs that could regulate gene expressions transcriptionally or post-transcriptionally through binding to 3' untranslated region (3'UTR) of target messenger RNAs (mRNAs), which were identified to be associated with tumorigenesis in various neoplasms. Among them, miR-101, encoded by two precursor transcripts (miR-101-1 and miR-101-2), was recognized to serve as a tumor suppressor via targeting critical oncogenes or anti-oncogenes. Additionally, studies have shown that miR-101 was participated in multiple cancer-related biological processes, including proliferation, apoptosis, angiogenesis, drug resistance, invasion and metastasis. In this review, we aim to summarize the function of miR-101 in different biological processes by figuring out the underlying target gene networks and explore its potential role as a biomarker in diverse neoplasms, which will provide a brand-new insight in molecular targeting cancer treatment.
