  • Neural stem cells (NSCs) in the adult hippocampus divide infrequently; the endogenous molecules modulating adult hippocampal neurogenesis (AHN) remain largely unknown. Here, we show that ErbB3 binding protein 1 (Ebp1), which plays important roles in embryonic neurodevelopment, acts as an essential modulator of adult neurogenic factors. In vivo analysis of Ebp1 neuron depletion mice showed impaired AHN with a low number of hippocampal NSCs and neuroblasts. Ebp1 leads to transcriptional repression of Bmp4 and suppression of Ascl1 promoter methylation in the dentate gyrus of the adult hippocampus reflecting an unusually high level of Bmp4 and low Ascl1 level in neurons of Ebp1-deficient mice. Therefore, our findings suggests that Ebp1 could act as an endogenous modulator of the interplay between Bmp4 and Ascl1/Notch signaling, contributing to AHN.

  • Human sterol ${\Delta}8-{\Delta}7$ isomerase, commonly known as emopamil binding protein (EBP), is an essential protein in the cholesterol-synthetic pathway, and mutations of this protein are critically associated with human diseases such as Conradi-Hunermann-Happle or male EBP disorder with neurological defects syndrome. Due to such a clinical importance, EBP has been intensively investigated and some important features have been reported. EBP is a tetra-spanning membrane protein, of which $2^{nd}$, $3^{rd}$, and $4^{th}$ membrane-spanning ${\alpha}$ helices play an important role in its enzymatic function. However, detailed structural feature at atomic resolution has not yet been elucidated, due to characteristic difficulties in dealing with membrane protein. Here, we over-expressed EBP using Escherichia coli and performed detergent screening to find suitable membrane mimetics for structural studies of the protein by NMR. As results, DPC and LMPG could be evaluated as the most favorable detergents to acquire promising NMR spectra for structural study of EBP.

  • Purpose: The purpose of this study was to identify community health practitioners' (CHP) perception of barriers to research utilization, current status and competence in evidence-based practice (EBP). Methods: From all over the country, 126 CHP completed an e-mail survey. Results: The items with the highest barrier scores were that it is difficult to understand articles written in English and physicians will not cooperate with implementation. There were statistically significant differences in the scores for attitude toward EBP and knowledge in EBP by education level and nursing academic society membership status. When faced with a problem, the nurses usually use related regulations or asked a colleague for advice. Conclusion: Results indicate an awareness of the necessity of applying EBP, need to improve readiness to use EBP voluntarily and actively, and need to search for various factors that are barriers to research utilization. There is a need to develop and apply EBP training/education programs to find new evidence that might actually support previous practice for which nurses lack confidence. Guidelines that consider CHP task characteristics and barrier factors to research utilization should be developed.

  • Purpose: The purpose of this study was to explore how knowledge management of hospital and nurses' beliefs and competences on evidence-based practice can affect evidence-based decision making. Methods: In this descriptive study, a total of 184 nurses who were working in the five general hospitals participated. The data were collected through a self-administered questionnaire in September, 2014. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and step-wise multiple regression with SPSS/WIN Statistics 21.0 program. Results: Evidence-based decision making was correlated with EBP beliefs (r=.55, p<.001), EBP competence (r=.57, p<.001), and knowledge management (r=.50, p<.001). Hierarchical regression analysis showed that EBP beliefs (${\beta}=.18$, p=.005), EBP competence (${\beta}=.37$, p<.001), organizational knowledge management (${\beta}=.27$, p<.001) explained 48.6% of evidence based decision making (p<.001). Conclusion: The study results indicated that evidence-based practice competences, organizational knowledge management, and evidence-based practice beliefs were important factors on evidence-based decision making. In order to improve evidence-based practice among nurses through organizational knowledge management, EBP beliefs and competence at individual level need to be considered and incorporated into any systemic training of EBP.

  • CCAAT/enhancer binding protein ${\alpha}$($C/EBP{\alpha}$) plays an important role in lipid deposition and adipocyte differentiation. In order to find genetic markers to improve the meat quality of Korean cattle, the bovine $C/EBP{\alpha}$ gene was chosen as a candidate gene to investigate its association with carcass and meat quality traits in Korean cattle. A single nucleotide polymorphism (SNP) was identified at position 271 (A/C substitution) of coding region in the $C/EBP{\alpha}$ gene. A PCR-RFLP procedure with restriction enzyme SmaI was developed for determining the marker genotypes. The frequencies of alleles C and A and were 0.374 and 0.626, respectively. The genotype frequencies for CC, AC and AA were 12.9, 49.0 and 38.1%, respectively, in Korean cattle population. The frequencies of genotype were in agreement with Hardy-Weinberg equilibrium. Association analysis indicated that the gene-specific SNP marker of $C/EBP{\alpha}$ showed a significant association with marbling score (p<0.05). The animals with AA genotype had higher marbling score than those with the AC or CC genotype. Although further studies are needed to validate our results, the $C/EBP{\alpha}$ gene could be useful as a genetic marker for carcass and meat quality traits in Korean cattle.

  • To explore the effects of deregulated expression of the EBNA1 binding protein 2 (EBP2) on cell growth, we generated human HEK293 stable clones constitutively expressing an EBP2-EGFP fusion protein. We found both RNA and protein levels of cyclin E1, a dominant oncoprotein, were elevated in the EBP2- EGFP stable clones. These findings were confirmed by flow cytometry bivariate analysis of cyclin expression versus DNA content. Moreover, the increase in p21 expression and the specific phosphorylation at Ser1981 of ATM and Ser15 of p53 were also observed in these stable clones, and these observations may explain the failure to observe an increase in Cdk2 kinase activity. In addition, after one year of passage culture, the EBP2-EGFP stable clones tended to lose 4 to 5 chromosomes per cell when compared to that of control cells. All of these findings provide a possible link between deregulated expression of EBP2 and tumor development.

  • 본 연구는 고지방식이를 섭취한 정소절제수술을 한 수컷 마우스에서 백색지방증가의 개선에 대한 testosterone의 영향과 그것에 대한 분자생물학적 조절기전을 규명하였다. Testosterone이 처리된 정소절제수술 마우스(CAST+T)는 정소절제수술 마우스 (CAST)에 비해 지방조직무게, 지방세포크기 및 $C/EBP{\alpha}$와 지방세포 표지유전자의 mRNA 발현이 감소되었다. 본 연구결과는 testosterone이 $C/EBP{\alpha}$$C/EBP{\alpha}$에 의해 조절되는 지방세포 표지 유전자들의 발현을 억제시킴으로써 지방세포 조절기전이 억제되고 지방조직의 무게가 감소된다는 것을 시사하고 있다. 따라서 본 연구는 성선기능저하증 남성의 비만조절에 대한 testosterone therapy의 유익한 분자생물학적 정보를 제공할 것이다.
