Insights

MicroRNAs (miRNAs) are crucial gene regulators and cancer players. Despite their potential as cancer biomarkers due to stability and detectability, challenges remain for clinical application.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biomarker Discovery

Background:

  • MicroRNAs (miRNAs) are key gene regulators discovered in 1993.
  • miRNAs are implicated in biological processes and human diseases, notably cancer.
  • Specific deregulation of miRNAs is observed in pathogenic cancer development.

Purpose of the Study:

  • To review the potential of miRNAs as cancer biomarkers.
  • To discuss the challenges hindering the clinical use of miRNAs in cancer diagnostics.
  • To identify pathways for establishing miRNAs as reliable cancer biomarkers.

Main Methods:

  • Literature review of miRNA research in cancer.
  • Analysis of miRNA properties relevant to biomarker applications.
  • Discussion of current limitations and future directions.

Main Results:

  • miRNAs exhibit chemical stability and sensitive detection methods.
  • miRNAs can be extracted from various clinical samples (tissues, fluids).
  • No miRNA has yet achieved practical clinical relevance as a cancer biomarker.

Conclusions:

  • miRNAs possess desirable characteristics for cancer biomarker development.
  • Overcoming current shortfalls is essential for clinical translation.
  • Further research is needed to establish miRNAs as reliable cancer biomarkers.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
