이 교수의 연구실은 주로 혈액세포종양, 특히 골수성 백혈병 및 림프종과 같은 혈액계 질환의 분자 기전과 치료 전략을 연구하고 있습니다. 특히 APL(급성 Promyelocytic Leukemia)의 새로운 유전자 융합형질과 duodenal-type follicular lymphoma와 같은 희귀 림프종의 임상적 특성에 초점을 맞추고 있으며, 생물정보학적 분석과 임상 데이터를 융합한 정밀의료 기반의 치료 전략 개발을 추구하고 있습니다.

We present an acute promyelocytic leukemia (APL) patient with two subtypes of IRF2BP2-RARA, in which the IRF2BP2 gene showed completely new breakpoints. Bone marrow examination revealed morphologic features indicative of APL. However, promyelocytic leukemia-RARA fusion was not detected. A paired-end mRNA sequencing followed by RT-PCR and direct sequencing revealed two types of fusion transcripts between exon 1B of IRF2BP2 and exon 3 of RARA. The patient received all-trans retinoic acid and conve
Iron–sulfur (FeS) proteins are ubiquitously distributed in organisms, playing essential roles in various biological processes as electron carriers, enzymes, and sensors of oxygen and iron.1-3 These functions depend on the chemical versatility of their cofactors, FeS clusters, which consist of several iron and sulfur atoms. Recent genetic and biochemical analyses have revealed that several enzymatic systems are involved in vivo in the synthesis of FeS clusters and in their incorporation into a
The crystal structures of the zeta-crystalline-like soluble quinone oxidoreductase from Thermus thermophilus HB8 (QOR(Tt)) and of its complex with NADPH have been determined at 2.3- and 2.8-A resolutions, respectively. QOR(Tt) is composed of two domains, and its overall fold is similar to the folds of Escherichia coli quinone oxidoreductase (QOR(Ec)) and horse liver alcohol dehydrogenase. QOR(Tt) forms a homodimer in the crystal by interaction of the betaF-strands in domain II, forming a large b
Duodenal-type follicular lymphoma (FL) is a rare and newly recognized disease. Few data are available on the outcomes and treatment strategies for patients with duodenal-type FL. We aimed to investigate the clinical features and outcomes of duodenal-type FL. We defined duodenal-type FL as involvement of the duodenum, without nodal or extranodal lesions other than intestinal lesions, pathologically diagnosed as FL. We reviewed 26 patients with duodenal-type FL between January 2011 and December 20
Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of diseases with variable outcomes. Although several prognostic markers have been developed, specific biomarkers for stratifying treatment strategies have not been fully investigated. This study aimed to analyze the clinical impact of the expression of cluster of differentiation (CD) 38, which is associated with cellular proliferation and disease progression, in patients with de-novo DLBCL. Using flow cytometry analysis, 137 cases wi
Though second allogenic haematopoietic stem cell transplantation (HSCT) is considered a curative treatment option after myelodysplastic syndrome (MDS) relapse, scant epidemiological data are available. We investigated the outcomes and prognostic factors of second allogenic HSCT in 99 patients with MDS who relapsed after the first HSCT. The median age was 53 years (interquartile; 45-59) and 57 patients (57·6%) were male. Five-year overall survival was 25·3%. Early relapse (adjusted hazard ratio:
In clinical trials, mRNA vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have shown remarkable efficacy and safety in healthy participants.1, 2 However, patients receiving anti-CD20 antibodies, such as rituximab or obinutuzumab (R/Obi), have been shown to have a poor humoral response to mRNA vaccines, although the response improves gradually if more time has elapsed.3, 4 R/Obi exerts an immunosuppressive effect through B-cell depletion, which could explain the impai
