연구실 소개

최지현 교수의 연구실은 장내 미생물 유래 외소체, 식물성 플라보노이드, 항산화제 등이 유도하는 내분비망역 스트레스와 세포 사멸 경로를 중심으로 염증 및 대사질환, 신경퇴행성질환의 분자 기전을 규명하고 있습니다. 특히, 유산균 유래 외소체와 천연물질이 염증 반응과 세포 손상을 조절하는 메커니즘을 밝혀내며, 장기적인 건강 유지와 질병 예방 전략 개발에 기여하고 있습니다. 최근에는 스마트 사회에서의 청자 호감도를 유도하는 음성 특성에 대한 다학제적 연구도 진행 중입니다.

SJR Q1Experimental & Molecular MedicineOA

Lactobacillus paracasei is a major probiotic and is well known for its anti-inflammatory properties. Thus, we investigated the effects of L. paracasei-derived extracellular vesicles (LpEVs) on LPS-induced inflammation in HT29 human colorectal cancer cells and dextran sulfate sodium (DSS)-induced colitis in C57BL/6 mice. ER stress inhibitors (salubrinal or 4-PBA) or CHOP siRNA were utilized to investigate the relationship between LpEV-induced endoplasmic reticulum (ER) stress and the inhibitory e

Baicalein protects HT22 murine hippocampal neuronal cells against endoplasmic reticulum stress-induced apoptosis through inhibition of reactive oxygen species production and CHOP induction
Ji Hyun Choi, A Young Choi, Hana Yoon, Wonchae Choe, Kyung‐Sik Yoon, Joohun Ha, Eui‐Ju Yeo, Insug Kang
SJR Q1Experimental & Molecular MedicineOA

Baicalein is one of the major flavonoids in Scutellaria baicalensis Georgi and possesses various effects, including cytoprotection and anti-inflammation. Because endoplasmic reticulum (ER) stress has been implicated in neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and cerebral ischemia, we investigated the effects of baicalein on apoptotic death of HT22 mouse hippocampal neuronal cells induced by thapsigargin (TG) and brefeldin A (BFA), two representative ER stres

α-Lipoic Acid Inhibits Expression of IL-8 by Suppressing Activation of MAPK, Jak/Stat, and NF-κB in H. pylori-Infected Gastric Epithelial AGS Cells
Ji Hyun Choi, Soon Ok Cho, Hyeyoung Kim
SJR Q2Yonsei Medical JournalOA

The epithelial cytokine response, associated with reactive oxygen species (ROS), is important in Helicobacter pylori (H. pylori)-induced inflammation. H. pylori induces the production of ROS, which may be involved in the activation of mitogen-activated protein kinases (MAPK), janus kinase/signal transducers and activators of transcription (Jak/Stat), and oxidant-sensitive transcription factor, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and thus, expression of interle

Sicyos angulatus Prevents High-Fat Diet-Induced Obesity and Insulin Resistance in Mice
Ji Hyun Choi, Jung‐Ran Noh, Yong‐Hoon Kim, Jae-Hoon Kim, Eunjung Kang, Dong‐Hee Choi, Jung Hyeon Choi, Jin‐Pyo An, Won Keun Oh, Chulho Lee
SJR Q2International Journal of Medical SciencesOA

Obesity is a medical condition in which excess body fat has accumulated to a serious extent. It is a chronic disease that can lead to dyslipidemia, insulin resistance, and type 2 diabetes. In the present study, we investigated the anti-obesity effects of <i>Sicyos angulatus</i> (SA) extract on a high-fat diet (HFD)-induced C57BL/6J obese mice. The mice were divided into vehicle and three SA groups (25, 50, and 100 mg/kg body weight). The mice were fed a HFD with or without SA for 12 weeks. The o

Hemoperitoneum Caused by Spontaneous Rupture of Uterine Leiomyoma in a Perimenopausal Woman
Ji Hyun Choi, Hyun Ju Liu, Soo Min Heo, Soo Ah Kim
Journal of Menopausal MedicineOA

Uterine fibroid, or leiomyoma, is a common benign neoplasm in women, but serious complications are rarely reported. We present the case of a 48-year-old woman with acute onset of abdominal pain. She was hemodynamically unstable, and computed tomography revealed abundant fluid collection in the peritoneal cavity, suggesting hemoperitoneum. During emergency exploratory laparotomy, the subserosal vein overlying a uterine fibroid was identified as the source of bleeding. Hemostasis was accomplished

현재와 같은 스마트 사회는 ICT 기술 및 통신 인프라 등의 발달로 말미암아 청자들이 느끼는 호감 있는 목소리가 과거와 달리 변하고 있다. 즉, 과거에는 크고, 강하고, 빠른 목소리를 호감 있는 목소리로 여겼다면 지금은 ICT 기술과 더불어 새로운 사회 문화가 이를 변화시키고 있다. 그러면 이제는 '현재와 같은 스마트 사회에서 어떤 목소리가 호감을 느끼는 목소리일까?'를 규명해 내는 것이 중요한 일 중 하나가 된다. 이를 위해 본 논문에서는 ICT 기술을 적용하여 청자들이 호감을 느끼는 목소리는 과연 어떤 목소리인지를 규명하였다. 연구는 크게 두 가지로 나누어 진행하였다. 첫째, 언어에 있어 소통과 관련된 요소들, 특히 정서적 기반의 말들이 실제 청자들의 호감도에 미치는 영향에 대한 실증 분석 작업을 정량화된 수치로 추출하였다. 이를 위해 일반인을 대상으로 한 실험을 행하였다. 둘째, 청자들이 호감을 느끼는 음성은 어떤 음성인지를 규명해 내는 작업을 수행하였다. 이를 위해 실제 사회

Influence of oxygen on characteristics of Zn(O,S) thin films deposited by RF magnetron sputtering

SJR Q2Journal of Vacuum Science & Technology A Vacuum Surfaces and Films

Zn(O,S) thin films were successfully deposited by reactive sputtering using Ar and O2 gas mixtures at 473 K. X-ray diffraction patterns revealed that the well crystallized Zn(O,S) films were deposited with increasing oxygen concentration in O2/Ar, resulting in a shift of the Zn peak of 28.5° to a higher angle, closer to the ZnO peak of 34.4°. Zn(O,S) films were composed of grains agglomerated from small particles, which grew gradually with increasing oxygen concentration. The depth profiles and

Abstract Mouse models expressing human ACE2 for coronavirus disease 2019 have been frequently used to understand its pathogenesis and develop therapeutic strategies against SARS-CoV-2. Given that human TMPRSS2 supports viral entry, replication, and pathogenesis, we established a double-transgenic mouse model expressing both human ACE2 and TMPRSS2 for SARS-CoV-2 infection. Co-overexpression of both genes increased viral infectivity in vitro and in vivo. Notably, double-transgenic mice showed sign
