Article Synopsis
  • Hepatocellular carcinoma (HCC) is a major global health concern and researchers are investigating copper isotope variations in serum as a potential biomarker for liver function and HCC prognosis.
  • The study involved analyzing serum samples from 293 patients with liver issues and 105 controls, discovering that low copper isotope values correlate with severe liver damage and HCC positivity.
  • The findings reveal a distinct bimodal distribution of copper isotopes that suggests a transition in liver tissue response to oxidative stress, highlighting existing challenges in identifying reliable biomarkers for early detection of HCC.

Hepatocellular carcinoma (HCC) is the second most common cause of cancer death worldwide, but is still lacking sensitive and specific biomarkers for early diagnosis and prognosis. In this study, we applied targeted massively parallel semiconductor sequencing to assess methylation on a panel of genes (FBLN1, HINT2, LAMC1, LTBP1, LTBP2, PSMA2, PSMA7, PXDN, TGFB1, UBE2L3, VIM and YWHAZ) in plasma circulating cell-free DNA (cfDNA) and to evaluate the potential of these genes as HCC biomarkers in two different series, one from France (42 HCC cases and 42 controls) and one from Thailand (42 HCC cases, 26 chronic liver disease cases and 42 controls). We also analyzed a set of HCC and adjacent tissues and liver cell lines to further compare with 'The Cancer Genome Atlas' (TCGA) data.

Chronic Hepatitis B (HB) is the main risk factor for chronic liver disease (CLD) and hepatocellular carcinoma (HCC) in many low-resource countries, where diagnosis is constrained by lack of clinical, histopathological and biomarker resources. We have used proteomics to detect plasma biomarkers that outperform α-Fetoprotein (AFP), the most widely used biomarker for HCC diagnosis in low-resource contexts. Deep-plasma proteome analysis was performed in HCC patients, patients with CLD and in HB-carrier controls from Thailand (South-East Asia) and The Gambia (West-Africa).
