研究室紹介
Professor Dong-geun Seol's research lab specializes in toxicology and molecular pathology, focusing on the biological effects of environmental pollutants and nanomaterials. The lab employs advanced proteomic technologies to investigate protein expression changes in response to exposure to formaldehyde, phthalates, polycyclic aromatic hydrocarbons, and copper oxide nanoparticles. Research directions include oxidative stress, cytotoxicity, genotoxicity, and inflammatory responses, with translational applications in disease mechanisms and biomarker discovery. The lab also explores host-pathogen interactions, as demonstrated by proteomic profiling in viral infections such as H1N1 influenza.

15Formaldehyde (FA) is known as a low molecule weight organic compound and one of major components that causes sick building syndrome (SBS), and it has been reported that FA has cytotoxic, hemotoxic, immunotoxic, and genotoxic properties. The International Agency for Research on Cancer (IARC) has characterized FA as a carcinogen. In this study, we investigated the effects of FA on rat plasma proteins by using proteomic approach. Rats were exposed to three different concentrations of FA (0, 5, 10 p
Intradiscal CFA injection led to chronic disk degeneration with allodynia, which was suggested by pain behavior and expression of pain-related mediators. The increment of CGRP, PGE, and iNOS also suggest pain-related signal processing between the IVD and the neural pathway in this animal model. This animal model may be useful for future research related to the pathophysiology and development of novel treatment for spine-related pain.
The effects of di(2-ethylhexyl) phthalate (DEHP) on proteins secreted by HepG2 cells were studied using a proteomic approach. HepG2 cells were exposed to various concentrations of DEHP (0, 2.5, 5, 10, 25, 50, 100, and 250 microM) for 24 or 48 h. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and comet assays were then conducted to determine the cytotoxicity and genotoxicity of DEHP, respectively. The MTT assay showed that 10 microM DEHP was the maximum concentration that did
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants of air, water and soil, and are produced by the incomplete combustion of organic materials. The International Agency for Research on Cancer has characterized PAHs as carcinogens. In this study, we investigated the effects of benzo(a)pyrene (B(a)P), which is the most carcinogenic member of the PAHs, on Jurkat cell protein by proteomic analysis. Jurkat cells were treated with various concentrations of B(a)P (0, 2.5, 5,
