Description

Homo sapiens hsa-mir-301b precursor miRNA

Summary

Caution, this is an AI generated summary based on literature. This may have errors.

MIR301B is a microRNA, a small non-coding RNA molecule, which plays a role in the regulation of gene expression [PMC8109121]. Its expression, along with other microRNAs such as miR-454, miR301a, miR130a, and miR130b, was quantified using the 2-ΔΔCt method with normalization to U6 [PMC8109121]. The study of these microRNAs led to further investigation into the influence of BHLHE40/41 on the expression levels of MIR130B and MIR301B [PMC6659797]. This suggests that BHLHE40/41 may be a regulatory factor affecting MIR301B expression [PMC6659797].
