Na Han 교수의 연구실은 간경변과 문맥 혈전증, 간암 등 간질환의 병태생리학적 기전과 진단, 치료 전략을 중심으로 한 간질환 연구를 주도하고 있습니다. 특히 간선막 혈전증의 개인화된 치료 전략, 간암에서의 전사 인자 DACH1의 종양억제 기전, 그리고 간에서의 혈전생성 및 신호전달 분자(예: PAR 수용체, 프로테아제)의 역할에 대한 기초 및 임상 연구를 병행하고 있습니다. 또한, 간에서의 약물 대사 및 영상 진단을 통한 종양과 유사 병변(예: CIFH)의 구별 방법 개발에도 기여하고 있습니다.

In patients with cirrhosis with PVT, the individualized treatment algorithm achieves a high-probability recanalization, with low rates of portal hypertensive complications and adverse events.
POHL development is associated with increased number of OBC sessions, and POHL severity was correlated with various biomarkers of SOS.
The traditional view of the role of proteases in tumor growth, progression and metastasis has significantly changed. Apart from their contribution to cancer progression, it is evident that a subclass of proteases, such as thrombin, serves as signal molecules controlling cell functions through the protease-activated receptors (PARs). Among the four types of PAR (PAR1-4; cloned and named in order of their discovery), PAR1, PAR3 and PAR4 are activated by thrombin, unlike PAR2, which is activated by
CIFH should be considered a mimicker of metastasis in patients with gastrointestinal malignancy during chemotherapy. CIFH can be differentiated from metastasis on the basis of gadoxetic acid-enhanced MR and DW imaging findings; an ill-defined margin on HBP images was especially characteristic.
Whole-genome and transcriptome sequencing of non-small cell lung cancer (NSCLC) identified that DACH1, is a human homolog of drosophila gene dac, is involved in NSCLC. Here we showed that expression of DACH1 was significantly decreased in human NSCLC tissues and DACH1 abundance was inversely correlated with tumor stages and grades. Restoration of DACH1 expression in NSCLC cells significantly reduced cellular proliferation, clone formation, migration and invasion in vitro, as well as tumor growth
Benzophenanthridine alkaloids belong to the benzyl isoquinoline family of alkaloids, which are mainly found in Papaveraceae and Rutaceae. To date, over.100 compounds have been isolated from natural herbal medicines which display a variety of pharmacological functions. In this paper, we have summarized the work since 1980 and our own research on benzophenanthridine alkaloids in terms of their chemical structures and distribution, biosynthesis, biotransformation and metabolism, spectral characteri
Growing teratoma syndrome can be manifested as intraperitoneal masses with an increased fatty or cystic component. Radiologists should consider GTS when there are such masses on follow-up imaging studies in patients with malignant ovarian GCT.
<b>Background:</b> Alzheimer's disease (AD) is a serious neurodegenerative disease associated with the memory and cognitive impairment. The occurrence of AD is due to the accumulation of amyloid <i>β</i>-protein (Aβ) plaques and neurofibrillary tangles (NFTs) in the brain tissue as well as the hyperphosphorylation of Tau protein in neurons, doing harm to the human health and even leading people to death. The development of neuroprotective drugs with small side effects and good efficacy is focuse
Two novel flavanone glycosides, homoeriodictyol 7-O-β-D-[6-(3-hydroxybutanoyl)glucopyranoside] (viscumneoside IX; 1) and homoeriodictyol 7-O-β-D-[6-(3-hydroxybutanoyl)glucopyranosyl](1→2)-β-D-glucopyranoside (viscumneoside X; 2), together with four known flavanoids, 2-homoeriodictyol 7-O-β-D-glucopyranoside (3), viscumneoside I (4), viscumneoside III (5), and 4',5-dihydroxy-3'-methoxy-7-(2-O-α-L-rhamnopyranosyl-β-D-glucopyranosyloxy)flavanone (6) were isolated from stems and leaves of Viscum col
Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease. However, the early diagnosis of NAFLD is challenging. Thus, the purpose of this study was to identify diagnostic biomarkers of NAFLD using machine learning algorithms. Differentially expressed genes between NAFLD and normal samples were identified separately from the GEO database. The key DEGs were selected through a protein‒protein interaction network, and their biological functions were analysed. Next, t
Recognition of PFS on the CT scan may warrant further evaluation of BOO and appropriate management to prevent renal impairment.
