Insights

Circulating microRNAs (miRNAs) in blood show promise as noninvasive biomarkers for gastrointestinal cancer (GIC). Research highlights their potential for early detection and improved GIC diagnostics.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Gastrointestinal cancer (GIC) is a major global health concern, necessitating advanced diagnostic and therapeutic approaches.
  • Noncoding RNAs (ncRNAs), including microRNAs (miRNAs), play crucial roles in cellular processes and disease development.
  • miRNAs are short RNA molecules that regulate gene expression and are implicated in cancer as oncogenes or tumor suppressors.

Purpose of the Study:

  • To review the current understanding of circulating miRNAs in relation to gastrointestinal cancer.
  • To explore the potential of these circulating miRNAs as noninvasive biomarkers for GIC detection and management.

Main Methods:

  • Literature review focusing on studies investigating circulating miRNAs in GIC patients.
  • Analysis of the stability and detectability of miRNAs in blood samples.
  • Evaluation of the diagnostic and prognostic value of specific circulating miRNAs in GIC.

Main Results:

  • Circulating miRNAs are stable in blood and can be detected noninvasively.
  • Specific miRNA profiles are associated with the presence and progression of GIC.
  • Several miRNAs show potential as sensitive and specific biomarkers for GIC.

Conclusions:

  • Circulating miRNAs represent a promising avenue for the development of novel, noninvasive biomarkers for gastrointestinal cancer.
  • Further research is warranted to validate these findings and translate them into clinical practice for improved GIC diagnostics.

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...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
