연구실 소개

구자현 교수의 연구실은 비만, 암 및 신장질환을 비롯한 만성질환의 생물학적 기전과 예후 예측 지표를 규명하는 데 초점을 맞추고 있습니다. 특히 림프절 밀도, 알부민 수치, 백혈구 및 혈소판 지표 등 간단하고 정량화 가능한 생물학적 마커를 활용해 암 환자의 예후를 정밀하게 평가하는 데 기여하고 있으며, 진단 및 치료 전략 수립에 기여할 수 있는 임상적 유용성을 강조합니다. 또한, 단백질 공학을 활용한 항체 모방 단백질 개발을 통해 새로운 진단 및 치료 도구 개발에도 기여하고 있습니다.

Voiding diary for the evaluation of urinary incontinence and lower urinary tract symptoms: Prospective assessment of patient compliance and burden
Ja Hyeon Ku, In Gab Jeong, Dae Jung Lim, Seok‐Soo Byun, Jae‐Seung Paick, Seung‐June Oh
SJR Q1FWCI 1.2Neurourology and Urodynamics

Our results suggest that keeping a diary for 7 days may increase patient burden and thus, we recommend that the 7-day diary should be reduced to cover fewer days.

Lymph node density as a prognostic variable in node-positive bladder cancer: a meta-analysis
Ja Hyeon Ku, Minyong Kang, Hyung Suk Kim, Chang Wook Jeong, Cheol Kwak, Hyeon Hoe Kim
SJR Q2FWCI 4.7BMC CancerOA

The data from this meta-analysis indicate that LN density is an independent predictor of clinical outcome in LN-positive patients. LN density may be useful in future staging systems, thus allowing better prognostic classification of LN-positive bladder cancer.

Alternate protein frameworks for molecular recognition.
Ja Hyeon Ku, Peter G. Schultz
SJR Q1FWCI 8.9Proceedings of the National Academy of SciencesOA

In an effort to determine whether proteins with structures other than the immunoglobulin fold can be used to mimic the ligand binding properties of antibodies, we generated a library from the four-helix bundle protein cytochrome b562 in which the two loops were randomized. Panning of this library against the bovine serum albumin (BSA) conjugate of N-methyl-p-nitrobenzylamine derivative 1 by phage display methods yielded cytochromes in which residues Trp-20, Arg-21, and Ser-22 in loop A and Arg-8

Health-Related Quality of Life in Patients with Spinal Cord Injury: Review of the Short Form 36-Health Questionnaire Survey
Ja Hyeon Ku
SJR Q2FWCI 2.5Yonsei Medical JournalOA

Advances in medical and rehabilitative care have increased interest in studying how different factors may affect the health-related quality of life (HRQOL) of individuals with spinal cord injury (SCI). There has been a large increase in the number of studies assessing HRQOL among persons with SCI. However, despite these advances, numerous issues remain unanswered because these studies have used a variety of methodologic approaches and assessment tools to examine how different factors have a role
