Cell-Free DNA Fragmentomics in Liquid Biopsy

Diagnostics, 2022
Cell-free DNA (cfDNA) in bodily fluids has rapidly transformed the development of noninvasive prenatal testing, cancer liquid biopsy, and transplantation monitoring. Plasma cfDNA consists of a mixture of molecules originating from various bodily tissues.

Emerging frontiers of cell-free DNA fragmentomics

Extracellular Vesicles and Circulating Nucleic Acids, 2022
Analysis of cell-free DNA (cfDNA) in the blood has shown promise for monitoring a variety of biological processes. Plasma cfDNA is a mixture comprising DNA molecules released from various bodily tissues, mediated by characteristic DNA fragmentations occurring during cell death.

At the dawn: cell-free DNA fragmentomics and gene regulation [PDF]

British Journal of Cancer, 2021
AbstractEpigenetic mechanisms play instrumental roles in gene regulation during embryonic development and disease progression. However, it is challenging to non-invasively monitor the dynamics of epigenomes and related gene regulation at inaccessible human tissues, such as tumours, fetuses and transplanted organs.

Cell-Free DNA Fragmentomics: The Novel Promising Biomarker

International Journal of Molecular Sciences, 2023
Cell-free DNA molecules are released into the plasma via apoptotic or necrotic events and active release mechanisms, which carry the genetic and epigenetic information of its origin tissues. However, cfDNA is the mixture of various cell fragments, and the efficient enrichment of cfDNA fragments with diagnostic value remains a great challenge for ...

Polyadenylation ligation‐mediated sequencing (PALM‐Seq) characterizes cell‐free coding and non‐coding RNAs in human biofluids

Clinical and Translational Medicine, Volume 12, Issue 7, July 2022., 2022
PALM‐Seq simultaneously characterizes the abundance and molecular signature of cell‐free coding and non‐coding RNAs. The profiles and end motifs of cf‐mRNA and cf‐lncRNA can distinguish biofluids. Seminal plasma tends to retain longer fragments than other biofluids.

Circulating DNA fragmentomics and cancer screening

Cell Genomics, 2023
The high fragmentation of nuclear circulating DNA (cirDNA) relies on chromatin organization and protection or packaging within mononucleosomes, the smallest and the most stabilized structure in the bloodstream. The detection of differing size patterns, termed fragmentomics, exploits information about the nucleosomal packing of DNA.

Epigenetic analysis of cell-free DNA by fragmentomic profiling

Proceedings of the National Academy of Sciences, 2022
Cell-free DNA (cfDNA) fragmentation patterns contain important molecular information linked to tissues of origin. We explored the possibility of using fragmentation patterns to predict cytosine-phosphate-guanine (CpG) methylation of cfDNA, obviating the use of bisulfite treatment and associated risks of DNA degradation.

Combining cell-free DNA fragmentomes and total tumour volume improves prognostication and tumour response evaluation in patients with colorectal cancer liver metastases. [PDF]

EBioMedicine
Background: Treatment decisions in patients with unresectable colorectal liver metastases (CRLM) are largely guided by radiological response to induction systemic therapy.

The Peptide MS/MS-Fragmentome: A Set of Predictable Fragment Ions with Highly Redundant Sequence Information [PDF]

, 2006
Upon low energy collision induced dissociation (CID), multiply protonated peptides generate a set of interdependent fragment ions detectable by MS/MS, the '[peptide]n+-fragmentome'.

Fragmentomic cfDNA Patterns in Noninvasive Prenatal Testing and Beyond

Journal of Biomedicine and Translational Research, 2021
The release of fetoplacental cell-free DNA (cfDNA) into the maternal bloodstream opened up new avenues towards noninvasive prenatal testing (NIPT) for aneuploidies, hereditary DNA mutations and other pregnancy-related developmental disorders. Increasingly, cfDNA catches interest for its noninvasive screening value in other areas as well, including ...
