연구실 소개
박철기 교수의 연구실은 신경과학과 신경외과학 분야에서 뇌신경세포의 기능과 기전을 규명하고, 뇌종양, 척추신경질환, 뇌신경통 등 신경계 질환의 분자 기전과 치료 전략을 탐구하고 있습니다. 특히 레이저, 전기생리학적 기법, 면역형광염색 등을 활용한 신경세포 기반의 분자표적 연구와, 뇌종양 내 줄기세포 특성 및 MGMT 프로모터 메틸화와 같은 생물학적 지표를 통한 예후 평가 및 치료 결정 지원 체계 개발에 주력하고 있습니다. 또한, 진단의 난관으로 여겨지는 가짜 진행(판정)의 분별을 위한 분자진단 기법 개발도 핵심 과제로 삼고 있습니다.

15Although eugenol is widely used in dentistry, little is known about the molecular mechanisms responsible for its anesthetic properties. In addition to calcium channels, recently demonstrated by our group, there could be another molecular target for eugenol. Using a whole-cell patch-clamp technique, we investigated the effect of eugenol on voltage-gated sodium channel currents (I(Na)) in rat dental primary afferent neurons identified by retrograde labeling with a fluorescent dye in maxillary mola
Short-term postoperative visual outcome was a strong indicator of permanent visual outcome after surgery for tuberculum sellae and diaphragm sellae meningiomas.
Intratumoral microhemorrhage is a possible mechanism of pathogenesis in cystic VS.
Sox2 is a key transcription factor that maintains the proliferation of neuroglial stem cells and inhibits neuronal fate commitment. Moreover, it was recently found that brain tumors contain stem cells that resemble normal neuroglial stem cells in many respects. This study was undertaken to describe Sox2 expression in various brain tumors, and to determine whether Sox2 expression is a universal feature of brain tumors, or whether its expression is limited to a specific lineage of brain tumors. So
We developed a practical scale to facilitate deciding whether to proceed with surgical management in patients with recurrent glioblastoma. This scale was useful for the diagnosis of prognostic groups and can be used to develop guidelines for patient treatment.
Pseudoprogression is a major diagnostic dilemma in current treatment protocols for malignant gliomas that involve concurrent chemoradiotherapy. We hypothesized that methylation-specific multiplex ligation probe amplification (MS-MLPA), an assay that permits semiquantitative evaluation of promoter methylation, may be used to diagnose pseudoprogression based on the quantification of the methylation status of the O(6)-methylguanine DNA methyltransferase (MGMT) promoter. We examined the methylation
We investigated the role of somatic mutations and a common single nucleotide polymorphism (SNP) in the hTERT promoter region on hTERT expression and clinical outcomes. The hTERT promoter region was sequenced from 48 glioblastomas. hTERT expression was analyzed by quantitative real time-PCR. The association between hTERT promoter genetic changes and other genomic events and clinical variables common in gliomas were examined. C228T and C250T somatic mutations were found in 60.4% of glioblastomas,
1. Distinct genomic profiles of 19 adult cerebellar GBMs were characterized. 2. MEK inhibitor was highly sensitive to cerebellar GBM compared with supratentorial GBM. 3. Master regulator analysis revealed NR4A1 as a potential therapeutic target in cerebellar GBM.
Purpose: This study was done to examine the effects of using standardized patients in psychiatric nursing practical training for nursing college students. Methods: This research design was a quasi-experimental pre-and-post-test control and experimental group methodological comparison study. Forty-four (Exp.=23, Cont.=21) nursing college students in G city participated in the study. The experimental group received psychiatric nursing practical training using standardized patients, and the control
The long-term clinical outcomes of CN after multimodal treatment seem to be excellent. Our study suggests that treatment strategies for CN should focus on the patient's quality of life, as well as on tumor control, because of the benign nature of CN.
