COVID-19 Research Reveals Novel Perspective on Virus-Mediated Oncogenesis

Strategic Insights -

New research conducted by researchers from Qingdao University has provided insights into the relationship between viruses, specifically hepatitis B and C, and liver cancer. The study, published in the Journal of Microbiology, analyzed the synonymous codon usage (RSCU) of three hepatitis viruses, SARS-CoV-2, and 30 human tissues, including hepatocellular carcinoma (HCC). The research revealed a strong association between hepatitis B and C viruses and HCC, as well as the adaptability of these viruses to the tRNA pool in HCC cells.

Key Takeaways:

  • Researchers from Qingdao University found that hepatitis B and C viruses show a high correlation with hepatocellular carcinoma (HCC), while SARS-CoV-2 has a strong association with lungs.
  • The study calculated the relative synonymous codon usage (RSCU) of hepatitis viruses, SARS-CoV-2, and human tissues, revealing a novel perspective on virus-mediated oncogenesis.
  • The research found that hepatitis B and C viruses preferentially adapt to the tRNA pool in HCC, facilitating rapid viral RNA translation and replication, which can change normal liver cells into HCC cells.
  • The journal Journal of Microbiology reported the research, with the title "Hepatitis B Virus (Hbv) Codon Adapts Well To the Gene Expression Profile of Liver Cancer: an Evolutionary Explanation for Hbv's Oncogenic Role."
  • Researchers Song Wang, Chunpeng Yu, Jian Li, Qun Li, Shuai Chang, Lingling Xie, Yufeng Cao, Hui Jiang, and Gang Fan contributed to the study.
  • The study was peer-reviewed and published in the Journal of Microbiology in 2022.

Statistics:

  • 30 human tissues, including hepatocellular carcinoma (HCC), were analyzed in the study.
  • The synonymous codon usage (RSCU) was calculated for three hepatitis viruses, SARS-CoV-2, and the 30 human tissues.
  • The study found a strong association between hepatitis B and C viruses and HCC.
  • 16,639 synonymous codons were analyzed in the study.
  • The codon adaptation index (CAI) was calculated for viral and human genes.
