Through the core laboratories he built and directed at Mayo Clinic, Dr. Sreekumar Raghavakaimal enabled researchers to apply cutting-edge genomic and proteomic tools to the study of liver disease — producing findings with direct clinical implications for hepatitis C treatment and liver transplantation outcomes.
Decoding Liver Disease at the Molecular Level
Liver disease — including hepatitis C (HCV), cirrhosis, and the complex immunological challenges of liver transplantation — presents some of medicine's most difficult diagnostic and therapeutic problems. Understanding why some patients respond to treatment while others do not requires insight at the level of gene expression and protein function.
The Genomics, Proteomics and Metabolic Core Laboratory directed by Dr. Raghavakaimal at Mayo Clinic provided exactly this capability — enabling liver disease researchers to profile thousands of genes simultaneously using microarray analysis, measure protein synthesis and turnover with stable isotope labeling, and build bioinformatics pipelines to interpret the resulting datasets.
This infrastructure directly supported multiple NIH-funded studies on liver disease, contributing to publications in Hepatology and Liver Transplantation — two of the highest-impact journals in the field. Dr. Raghavakaimal's technical expertise in mass spectrometry and microarray analysis was essential to studies examining protein kinetics in the liver, viral gene expression in HCV infection, and genomic biomarkers of transplant rejection.
Research Contributions
Hepatitis C
Genomic profiling of HCV-infected liver tissue to identify host gene expression patterns associated with viral response, fibrosis progression, and treatment outcomes.
Liver Transplantation
Proteomic and genomic analysis of transplanted liver tissue, supporting research into rejection mechanisms, immune tolerance, and post-transplant outcomes.
Protein Metabolism
Stable isotope studies of hepatic protein synthesis and turnover — providing a quantitative framework for understanding how liver disease alters protein metabolism.
Liver Research in Leading Journals
Dr. Raghavakaimal's contributions to liver disease research are reflected in publications in Hepatology and Liver Transplantation, both flagship journals of the American Association for the Study of Liver Diseases (AASLD). His work supported some of the earliest applications of microarray genomics and tandem mass spectrometry to liver disease research at a major academic medical center.

Why This Research Matters
Liver disease affects hundreds of millions of people worldwide. Hepatitis C alone was once the leading indication for liver transplantation in the United States. Understanding the genomic and proteomic basis of disease progression and treatment response is essential to developing better therapies.
The core laboratory capabilities that Dr. Raghavakaimal established at Mayo Clinic — and the research they enabled — contributed directly to the scientific foundation on which modern precision medicine approaches to liver disease are built.
