Insights

Secretory microRNAs (miRNAs) in body fluids show promise as non-invasive cancer biomarkers. Their levels correlate with cancer progression and survival, aiding early diagnosis and treatment prediction.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
  • miRNA dysregulation is implicated in various stages of cancer development and progression.
  • Secretory miRNAs in biofluids are emerging as significant indicators of cancer status.

Purpose of the Study:

  • To review the role of secretory miRNAs in different cancer types.
  • To analyze mechanisms of miRNA secretion and detection methods.
  • To evaluate secretory miRNAs as biomarkers for cancer diagnosis and therapeutic response.

Main Methods:

  • Literature review and synthesis of current research on secretory miRNAs in oncology.
  • Analysis of studies investigating miRNA secretion mechanisms.
  • Evaluation of diagnostic and prognostic potential of secretory miRNAs.

Main Results:

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 (lncRNA)...

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 ends...
