44 Current Challenges in miRNomics.

Methods Mol Biol

January 2022

Medical Informatics and Bioinformatics, Institute for Measurement Engineering and Sensor Technology, Hochschule Ruhr West, University of Applied Sciences, Mülheim adR, Germany.

Article Synopsis
  • Mature microRNAs (miRNAs) are short RNA sequences crucial for regulating target RNAs post-transcriptionally, following a complex production process that starts in the nucleus and ends with their incorporation into RISC in the cytosol.
  • The binding of these miRNAs to target mRNAs can either degrade the mRNA or inhibit translation, which affects protein production, but in some cases, it can enhance protein synthesis instead.
  • Despite substantial research, there are still challenges in computationally predicting miRNA regulation, which is necessary for understanding the intricate miRNA-target interactions and could lead to advancements in the field.
