MIR301B: MIR301B is a microRNA that has been studied in relation to its expression levels [PMC8109121]. In a study, the expressions of miR-454, miR301a, MIR301B, miR130a, and miR130b were normalized to U6 using the 2-ΔΔCt method [PMC8109121]. This method is commonly used to analyze gene expression levels. The study aimed to investigate the impact of BHLHE40/41 on the expression of MIR130B and MIR301B [PMC6659797]. BHLHE40/41 is a transcription factor that has been associated with various biological processes and diseases [PMC6659797]. By studying its influence on MIR130B and MIR301B expression, researchers aimed to gain insights into the regulatory mechanisms involved in microRNA expression [PMC6659797]. The findings of this study could potentially contribute to a better understanding of the roles played by microRNAs in cellular processes and disease development [PMC6659797]. Further research may be needed to fully elucidate the specific mechanisms by which BHLHE40/41 influences MIR130B and MIR301B expression [PMC6659797].
