연구실 소개

이 교수의 연구실은 간질환, 특히 간선자세와 간세포암의 발달 기전에 초점을 맞추고 있으며, 간 섬유화, 염증 반응 및 종양 미세환경의 분자 기전을 규명하는 데 주력하고 있습니다. 특히 TGF-β, PDGF 등 성장인자 신호 경로와 근막세포, 신경세포, 콜라겐 형성 세포의 역할을 중심으로 간질환의 진행 메커니즘을 분석하고 있습니다. 또한, 암의 치료 반응과 예후에 영향을 미치는 마이크로혈관 침범, 지방간, 간세포암의 면역형질 분류 등 임상적 요소와의 연관성도 깊이 연구하고 있습니다.

Effects of Statin Use on the Development and Progression of Nonalcoholic Fatty Liver Disease: A Nationwide Nested Case-Control Study
Jung Il Lee, Hyun Woong Lee, Kwan Sik Lee, Hye Sun Lee, Ju-Young Park
SJR Q1The American Journal of GastroenterologyOA

INTRODUCTION: The use of statins in nonalcoholic fatty liver disease (NAFLD) may reduce cardiovascular morbidity, although their effect on NAFLD itself is not well known. We aimed to investigate the role of statins on the development of de novo NAFLD and progression of significant liver fibrosis. METHODS: This study included 11,593,409 subjects from the National Health Information Database of the Republic of Korea entered in 2010 and followed up until 2016. NAFLD was diagnosed by calculating fat

Decreased density of interstitial cells of Cajal and neuronal cells in patients with slow‐transit constipation and acquired megacolon
Jung Il Lee, Hyojin Park, Michael A. Kamm, Ian Talbot
SJR Q1Journal of Gastroenterology and HepatologyOA

BACKGROUND: The pathophysiology of constipation is not clearly identified as yet, and the interstital cells of Cajal (ICC), known to generate the slow wave activity and to be involved in intestinal neurotransmission and the enteric nervous system (ENS), are suspected to play an important role. The aims of the present study were to assess the distribution of ICC and neuronal cells of ENS in patients with slow-transit constipation and acquired megacolon. METHODS: Sigmoid colon specimens were obtai

Primary liver cancers with biliary components tended to show poorer surgical outcome. This suggested that immuno-phenotype of liver cancers was as important as their morphological classification.

Transarterial chemoembolization versus surgery/radiofrequency ablation for recurrent hepatocellular carcinoma with or without microvascular invasion

SJR Q1Journal of Gastroenterology and Hepatology

BACKGROUND/AIMS: Microvascular invasion (MVI) is a well-known prognostic factor of postoperative recurrence and of overall survival (OS) in patients with hepatocellular carcinoma (HCC). We compared the treatment outcomes of transarterial chemoembolization (TACE) and surgery/radiofrequency ablation (RFA) according to the presence of MVI in patients with early or late recurrent HCC that presented as Barcelona Clinical Liver Cancer (BCLC) stage 0 or A after curative resection for HCC. METHODS: A co

SJR Q1American Journal of Physiology-Cell PhysiologyOA

Chronic liver injury leads to fibrosis and cirrhosis. Cirrhosis, the end stage of chronic liver disease, is a leading cause of death worldwide and increases the risk of developing hepatocellular carcinoma. Currently, there is a lack of effective antifibrotic therapies to treat fibrosis and cirrhosis. Development of antifibrotic therapies requires an in-depth understanding of the cellular and molecular mechanisms involved in inflammation and fibrosis after hepatic injury. Two growth factor signal

Non-alcoholic fatty liver disease (NAFLD) is associated with an increased hepatocellular carcinoma (HCC) risk. We established and validated a liver stiffness (LS)-based risk prediction model for HCC development in patients with NAFLD. A total of 2666 and 467 patients with NAFLD were recruited in the training and validation cohorts, respectively. NAFLD was defined as controlled attenuated parameter ≥238 dB/m by transient elastography. Over a median of 64.6 months, HCC developed in 22 (0.8%) subje

SJR Q1The OncologistOA

BACKGROUND: Unlike tamoxifen, the relationship between aromatase inhibitor use in postmenopausal patients with breast cancer and nonalcoholic fatty liver disease (NAFLD) has not been delineated. MATERIALS AND METHODS: A retrospective analysis of 253 patients with early breast cancer without baseline NAFLD and treated with nonsteroidal aromatase inhibitors was performed. Among them, 220 patients were matched for sex, age, and menstruation status with healthy patients, and the prevalence of NAFLD

Omega-3 polyunsaturated fatty acid and ursodeoxycholic acid have an additive effect in attenuating diet-induced nonalcoholic steatohepatitis in mice

SJR Q1Experimental & Molecular MedicineOA

Nonalcoholic steatohepatitis (NASH) can progress into liver cirrhosis; however, no definite treatment is available. Omega-3 polyunsaturated fatty acid (omega-3) has been reported to alleviate experimental NASH, although its beneficial effect was not evident when tested clinically. Thus, this study aimed to investigate the additive effect of omega-3 and ursodeoxycholic acid (UDCA) on diet-induced NASH in mice. C57BL/6 mice were given a high-fat diet (HFD) for 24 weeks, at which point the mice wer

Progression of diet induced nonalcoholic steatohepatitis is accompanied by increased expression of kruppel-like-factor 10 in mice

SJR Q1Journal of Translational MedicineOA

BACKGROUND: Kruppel-like-factor (KLF) 10 is identified as transforming growth factor (TGF) β inducible early gene and is reported to suppress lipogenic genes. Although previous studies report that TGFβ plays an important role in progression of nonalcoholic steatohepatitis (NASH) by regulating liver fibrosis, the association of KLF10 and NASH has never been explored. Thus we evaluated expressions and changes of KLF10 in diet induced NASH and in NASH which was alleviated by ursodeoxycholic acid (U

Selective deletion of hepatocyte platelet-derived growth factor receptor α and development of liver fibrosis in mice

SJR Q1Cell Communication and SignalingOA

BACKGROUND: Platelet-derived growth factor receptor α (PDGFRα) expression is increased in activated hepatic stellate cells (HSCs) in cirrhotic liver, while normal hepatocytes express PDGFRα at a negligible level. However, cancerous hepatocytes may show upregulation of PDGFRα, and hepatocellular carcinoma is preceded by chronic liver injury. The role of PDGFRα in non-cancerous hepatocytes and liver fibrosis is unclear. We hypothesized that upon liver injury, PDGFRα in insulted hepatocytes contrib
