Transformer‐based representation learning and multiple‐instance learning for cancer diagnosis exclusively from raw sequencing fragments of bisulfite‐treated plasma cell‐free DNA

Molecular Oncology, Volume 18, Issue 11, Page 2755-2769, November 2024.
This study introduces DECIDIA, a deep‐learning approach for early cancer diagnosis using bisulfite‐treated cfDNA sequencing fragments. Utilizing transformer‐based representation learning and weakly supervised multiple‐instance learning, DECIDIA accurately detects cancer and predicts cancer types, significantly simplifying data analysis.

Fragmentomics of urinary cell-free DNA in nuclease knockout mouse models

PLOS Genetics, 2022
Urinary cell-free DNA (ucfDNA) is a potential biomarker for bladder cancer detection. However, the biological characteristics of ucfDNA are not well understood. We explored the roles of deoxyribonuclease 1 (DNASE1) and deoxyribonuclease 1-like 3 (DNASE1L3) in the fragmentation of ucfDNA using mouse models.

Plasma Cell‐Free DNA Concentration and Fragmentomes Predict Neoadjuvant Chemotherapy Response in Cervical Cancer Patients

Advanced Science, Volume 11, Issue 43, November 20, 2024.
Cervical cancer patients with varying responses to neoadjuvant chemotherapy (NACT) exhibit unique patterns of variation in cell‐free DNA (cfDNA) levels and fragmentomic characteristics. The cfDNA emerges as a promising biomarker for predicting tumor response to NACT in cervical cancer, offering a novel approach for monitoring treatment response to ...

Circulating tumor DNA methylation detection as biomarker and its application in tumor liquid biopsy: advances and challenges

MedComm, Volume 5, Issue 11, November 2024.
The origin of ctDNA in the bloodstream is derived from CTC, exosomes secreted by tumor cells, apoptotic tumor cells and necrotic tumor cells (A). ctDNA methylation status plays an important role in the occurrence and development of cancer and is a biomarker for tumor liquid biopsy.

Circulating Cell-free DNA Fragmentomics Detection and Beyond

aging and disease
Circulating cell-free DNA (cfDNA) comprises DNA fragments released into bodily fluids via apoptosis, necrosis, or phagocytosis. cfDNA encapsulates both fragmentomics (structural) and non-fragmentomics (sequence/epigenetic) information from source cells, thereby representing a promising biomarker.

Analysis of cfDNA fragmentomics metrics and commercial targeted sequencing panels

Nature Communications
Abstract Fragmentomics based analysis of cell-free DNA (cfDNA) has recently emerged as a method to infer epigenetic and transcriptional data. Many of these reports analyze whole genome sequencing (WGS) which is not readily available clinically. Targeted exon panels are used for clinical cfDNA variant calling.
