Genetic variant linked to development of liver cancer in hepatitis C virus carriers

04.07.2011
A genome-wide study by researchers at the RIKEN Center for Genomic Medicine, Hiroshima University Hospital and Sapporo-Kosei General Hospital has identified a genetic variant associated with the development of liver cancer in chronic hepatitis C virus carriers. The findings are based on a study of 3,312 Japanese individuals and appear in the journal Nature Genetics.

Hepatocellular carcinoma (HCC), the most common type of liver cancer, is the third leading cancer-related cause of death and the seventh most common form of cancer worldwide. The hepatitis C virus (HVC) is the main risk factor for HCC in many western countries and in Japan, where of the more than 30,000 deaths each year from HCC, 70% involve HVC.

To identify risk factors connecting HVC and HCC, the research group conducted a genome-wide study on a group of 3,312 Japanese individuals carrying the hepatitis C virus. Analyzing a total of 467,538 genetic markers (called single nucleotide polymorphisms or SNPs) in a group of 212 HCV carriers with HCC and 765 HCV carriers without HCC, the group uncovered one SNP associated with HCC risk, located on a gene called DEPDC5. The association was confirmed in an independent replication study on a population of 2335 HVC carriers, 710 with HCC and 1625 without HCC.

The significance of the findings was further highlighted when the researchers adjusted their results for gender, age and platelet count, revealing that among Japanese individuals with chronic HVC infection, the DEPDC5 SNP roughly doubles the odds of developing HCC.

While deepening our understanding of the mechanisms triggering HCC, the discovery of the DEPDC5 SNP locus also provides a valuable target for new therapy techniques, promising progress in the ongoing battle to overcome one of the world's most deadly cancers.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
