Professor Sangkyu Lee's research lab specializes in molecular toxicology and systems biology, focusing on the mechanisms of drug-induced and environmental toxicities, particularly in the liver and nervous system. The lab employs multi-omics approaches—integrating transcriptomics, proteomics, and metabolomics—to dissect the pathophysiological mechanisms of diseases such as tuberculosis-related liver injury, perfluorooctanesulfonic acid (PFOS) neurotoxicity, and castration-resistant prostate cancer. A key focus is on post-translational modifications, including novel histone modifications like lysine acetoacetylation, and the role of metabolic enzymes such as SIRT5 in cancer progression. The lab also investigates drug metabolism and pharmacokinetics across species to support translational drug development.

Tuberculosis is one of the top causes of death among curable infectious diseases; it is an airborne infectious disease that killed 1.1 million people worldwide in 2010. Anti-tuberculosis drug-induced liver injury is the primary cause of drug-induced liver injury (DILI). Rifampicin is one of the most common anti-tuberculosis therapies and has well-known hepatotoxicity. To understand the mechanism of rifampicin-induced liver injury, we performed a global proteomic analysis of liver proteins by LC-
Limited studies on multi-omics have been conducted to comprehensively investigate the molecular mechanism underlying the developmental neurotoxicity of perfluorooctanesulfonic acid (PFOS). In this study, the locomotor behavior of zebrafish larvae was assessed under the exposure to 0.1-20 μM PFOS based on its reported neurobehavioral effect. After the number of zebrafish larvae was optimized for proteomics and metabolomics studies, three kinds of omics (i.e., transcriptomics, proteomics, and meta
Prostate cancer (PCa) is the most commonly diagnosed genital cancer in men worldwide. Around 80% of the patients who developed advanced PCa suffered from bone metastasis, with a sharp drop in the survival rate. Despite great efforts, the detailed mechanisms underlying castration-resistant PCa (CRPC) remain unclear. Sirtuin 5 (SIRT5), an NAD<sup>+</sup>-dependent desuccinylase, is hypothesized to be a key regulator of various cancers. However, compared to other SIRTs, the role of SIRT5 in cancer
Ketone bodies have long been known as a group of lipid-derived alternative energy sources during glucose shortages. Nevertheless, the molecular mechanisms underlying their non-metabolic functions remain largely elusive. This study identified acetoacetate as the precursor for lysine acetoacetylation (Kacac), a previously uncharacterized and evolutionarily conserved histone post-translational modification. This protein modification is comprehensively validated using chemical and biochemical approa
DWP16001 is currently in a phase 2 clinical trial as a novel anti-diabetes drug for the treatment of type 2 diabetes by selective inhibition of sodium-glucose cotransporter 2. This in vitro study was performed to compare the metabolism of DWP16001 in human, dog, monkey, mouse, and rat hepatocytes, and the drug-metabolizing enzymes responsible for the metabolism of DWP16001 were characterized using recombinant human cytochrome 450 (CYP) and UDP-glucuronosyltransferase (UGT) enzymes expressed from
