Harnessing viral footprints in circulating free DNA (cfDNA) for early cancer detection: A focus on liquid‐biopsy‐based screening

International Journal of Cancer, Volume 158, Issue 3, Page 511-526, 1 February 2026.
Abstract Viral infections play a significant role in cancer development, making detecting viral signatures a promising approach for early cancer diagnosis. Circulating free DNA (cfDNA), released into the bloodstream by tumors and other cells, has emerged as a powerful biomarker for non‐invasive cancer screening.

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Seroprevalence of HTLV-1 and HTLV-2 amongst mothers and children in Malawi within the context of a systematic review and meta-analysis of HTLV seroprevalence in Africa [PDF]

, 2016
OBJECTIVES: Human T‐lymphotropic virus (HTLV)‐1 causes T‐cell leukaemia and myelopathy. Together with HTLV‐2, it is endemic in some African nations. Seroprevalence data from Malawi are scarce, with no reports on associated disease incidence.

Enzyme Immunoassay with Synthetic Peptides to Detect Anti-HTLV-I Antibodies

Clinical Chemistry, 1992
Abstract We developed an enzyme immunoassay (EIA) system to detect antibodies to human T-lymphotropic virus type I (HTLV-I). This system uses chemically synthesized oligopeptides to capture anti-HTLV-I antibodies in serum. The two epitopes of HTLV-I proteins exhibiting the most specific antigen-antibody reaction reside within amino acids
