About the Lab

Professor Jeongil Son's research lab focuses on the interplay between metabolic disorders, liver disease, and gastrointestinal malignancies, with a particular emphasis on non-alcoholic fatty liver disease (NAFLD), insulin resistance, and their systemic implications. The lab investigates the roles of obesity, sarcopenia, systemic inflammation, and metabolic syndrome in the development of colorectal neoplasms and liver dysfunction. Using large-scale population-based cross-sectional studies and clinical imaging, the lab aims to identify independent risk factors and pathophysiological mechanisms linking metabolic health to gastrointestinal and hepatic diseases. The research also explores the clinical significance of incidental adrenal masses and their association with systemic conditions such as paroxysmal hypertension and hormonal excess.

SJR Q1Journal of Gastroenterology and Hepatology

BACKGROUND AND AIM: Differences in the prevalence of non-alcoholic fatty liver disease (NAFLD) between Eastern and Western populations are primarily attributable to differences in definitions and biased population selection. Thus, the aim of the present study was to accurately determine the actual prevalence of NAFLD by sonography and to characterize the risk factors for NAFLD. METHODS: The present cross-sectional study was performed with data obtained from 6,648 subjects, all of whom were older

Insulin resistance and C‐reactive protein as independent risk factors for non‐alcoholic fatty liver disease in non‐obese Asian men

SJR Q1Journal of Gastroenterology and HepatologyOA

BACKGROUND AND AIM: Although insulin resistance is often considered the link between obesity and non-alcoholic fatty liver disease (NAFLD), the role of insulin resistance, independent of obesity, as a NAFLD risk factor in non-obese men has been less well established. Systemic inflammation may be accompanied by insulin resistance in healthy subjects. The goal of the present study was to examine if insulin resistance and systemic inflammatory markers are independent predictors of NAFLD in non-obes

SJR Q1Journal of Gastroenterology and HepatologyOA

BACKGROUND AND AIMS: Metabolic syndrome and insulin resistance are associated with a higher risk of colon cancer. Non-alcoholic fatty liver disease (NAFLD) is regarded as a manifestation of metabolic syndrome in the liver. This investigation was initiated to determine whether NAFLD has a relationship to colorectal adenomatous polyps. METHODS: We examined the 2917 participants who underwent a routine colonoscopy at Kangbuk Samsung Hospital in 2007. We divided the 2917 subjects into the adenomatou

SJR Q2Journal of Clinical Gastroenterology

GOALS: We aimed to ascertain whether low relative muscle mass is associated with colorectal neoplasm (CRN) risk. BACKGROUND: CRN and sarcopenia have common pathophysiological mechanisms such as insulin resistance, chronic inflammation, and physical inactivity. However, the direct relationship between the 2 diseases has not been investigated. STUDY: A cross-sectional study was performed on 81,885 examinees who underwent colonoscopy as part of a health check-up. The skeletal muscle mass index (SMI

A 40-year-old woman was admitted because of abdominal pain and diarrhea. She sometimes experienced paroxysmal hypertension, sweating, headache, and palpitation. Sigmoidoscopic findings showed well-demarcated diffuse mucosal edema, hyperemia, and easy touch bleeding from distal descending colon up to the splenic flexure area. Barium x-ray showed loss of haustral marking, thumb printing appearance, and diffuse luminal stenosis in the transverse, descending, and sigmoid colon. On the abdominal comp

Adenosine Receptor Agonists Modulate Visceral Hyperalgesia in the Rat

SJR Q1Gut and LiverOA

Adenosine receptor agonists are antihyperalgesic, but also produce motor weakness at high doses. However, activation of the spinal A1 receptor significantly attenuates the VMR to CRD without producing motor weakness.

Sex Differences in the Relation between Waist Circumference within the Normal Range and Development of Reflux Esophagitis

SJR Q1Journal of Clinical MedicineOA

We examined the association of abdominal obesity and waist circumference within normal range with the incidence of reflux esophagitis, separately in men and women. This cohort study involved 142,679 Korean adults without reflux esophagitis, who underwent upper endoscopy at baseline and during follow-up. Waist circumference was categorized into the following quartiles: <80, 80.1–85, 85.1–90, and ≥90.1 cm in men; and <69.3, 69.3–74, 74.1–79.5, and ≥79.6 cm in women. During the 551,877.8 pers
