Circulating nucleic acids in plasma show promise for non-invasive diagnostics in cancer and pregnancy. Further research into their origins and standardization is crucial for advancing molecular diagnostics.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Clinical Diagnostics

Background:

  • Circulating nucleic acids (CNAs) in plasma, discovered in 1948, have evolved into significant diagnostic tools.
  • CNAs include circulating tumor DNA (ctDNA) for cancer diagnostics and fetal DNA for non-invasive prenatal testing (NIPT).
  • Emerging research highlights the importance of circulating tumor RNA (ctRNA) and fetal RNA, mirroring the utility of their DNA counterparts.

Purpose of the Study:

  • To review the diagnostic and prognostic applications of circulating nucleic acids.
  • To highlight advancements in fetal-derived DNA and RNA detection for prenatal diagnosis and monitoring.
  • To discuss the potential of CNAs in other clinical areas like traumatology and transplant monitoring.

Main Methods:

  • Literature review of studies on circulating DNA and RNA in various medical conditions.
  • Analysis of established and emerging applications of CNAs in diagnostics.
  • Discussion of ongoing research into CNA origins and release mechanisms.

    • Main Results:

    • Demonstrated diagnostic and prognostic value of ctDNA across multiple cancer types.
    • Successful implementation of non-invasive fetal Rhesus blood group genotyping.
    • Reported successful prenatal diagnosis of Down's syndrome using fetal RNA analysis.
    • Identified potential applications of CNAs in traumatology and transplant monitoring.

    Conclusions:

    • Circulating nucleic acids offer a wide range of promising applications in molecular diagnostics.
    • Further understanding of CNA origins and release mechanisms is needed.
    • Standardization of pre-analytical methods is essential for reliable data comparison across laboratories.
    • CNAs are poised to drive significant advancements in diagnostics in the coming years.
