Potential use of transgenic domestic pigs expressing recombinant human erythropoietin in diabetes translation research

백선영,정학재,김경운,조규호,최인철,이훈택 한국통합생물학회 2019 Animal cells and systems Vol.23 No.1

Recently, diabetes mellitus (DM) has shown rapid global increases with about five million deaths annually. Animal models are imperative to understand disease mechanisms and develop diagnostic, preventive, and therapeutic interventions in translational research. Rodent and minipig models have been established and widely used for DM research. However, domestic pig models are limited in spite of advantages such as pharmacokinetic and physiopathological availability. This study examines the potential use of domestic pigs expressing recombinant human erythropoietin (rhEPO) as disease and therapeutic response models for DM. We previously generated transgenic pigs (n = 16, EPO Tg) in which rhEPO was expressed and circulated in all organs. Thirty-two pigs, including 16 controls, were fed high fat (HF) diets for 42 weeks. Subsequently, blood samples for chemical and metabolic analysis were collected after fasting for 24 h and glucose loading for oral glucose tolerance tests (OGTTs). We found increased activation of the PI3 K/Akt signaling pathway under hypoxic conditions after rhEPO treatment, and HF diet-inducible-obesity in the EPO Tg and control pigs. OGTTs showed lower fasting glucose levels in the EPO Tg pigs than in controls before and after the HF diet, suggesting that rhEPO may affect glucose concentrations. Insulin and C-peptide concentrations responded slowly to glucose administration and returned to initial levels after 2 h. The blood test results suggest that EPO might affect metabolic and chemical components such as glucose, high-density lipoprotein, glucagon, triglyceride, and free fatty acid. Our findings support the use of rhEPO transgenic domestic pigs as model animals for translational DM research.

The purpose of this study was to discover the experiences and changes of the violin student’s in the ‘El Sistema Korea’ orchestra program. Participating observations, classroom observations, activity journals, group interviews and in-depth interviews with participants in the study, and recordings were taken in order to collect data for this research. The conclusions of this study are as follows. First, ‘El Sistema Korea’ orchestra education has allowed students to experience a variety of activities that they have never experienced in a more practical way before, which has contributed to expanding there artistic experience. Second, the ‘El Sistema Korea’ orchestra education has improved the students’ self-confidence and self-esteem, and these personal changes have produced positive improvements in their social skills. Finally, the students’ interest to enjoy music in life, to major in music, and to enjoy art in life improved consistently through the ‘El Sistema Korea’ orchestra education. However, despite these positive factors, the opportunity costs to study was a decisive factor in forcing them to abandon their orchestra education.

Recently, as concern about the residual antibiotics in milk increase, the detection methods of residual antibiotics used extensevely at the present time were investigated and compared to their properties and the detection limits of variable antibiotics. At first, comparative tests of the detectable sensitivity of 4 teat organisms, B.cereus, B.subtilis, M.luteus, B. stearothermophilus C-953, were performed by disc assay. As a result, B.stearotleermoph.ilus was the most sensitive strain of all other strains and showed the detect limit of 5-50 ppb for penicillins (PCs). And also, B.subtilis was showed the more effective detection limit, 200-400 ppb, for aminoglycosides (AGs) and M.luteus was showed predominant sensitivity , 50-500 ppb for macrolides(MLs) and B.cereus was the most sensitive strain for tetracyclines (TCs) and showed the detection limit of 100-400 ppb. Therefore, each test strains were showed a different sensitivity in the detection of the different antibiotic families. When the detection limit of disc assay and other methods were compared, TTCmethod was less sensitive than other methods showing 5-50 ppb detectable lebel for PCs. Also, for the detection of other antibiotic families TTC method was showed the worst sensitivity and Delvo and Charm Farm tests were similar to the detectable properties of AGs and MLs. Although disc assay was showed the similar detection limit for PCs with Delvo and Charm Farm, it was more widely effective for the detection of kanamycin, erythromycin, chlortetracycline, doxycycline, verginiamycin and so on than Delvo or Charm Farm. CharmII test was showed the best sensitivity for the most of antibiotics except neomycin and gentamycin. But it was necessary that different tests must be performed to each antibiotic family and so it was regarded that the effectiveness of that method was low.

자외선 조사와 NTG를 처리하여 Brevibacterium flavum 10AHR(arg his Rif^r)과 Corynebacterium glutamicum 11TS(trp Sm^r)의 돌연변이주를 분리하였다. B. flavum 10AHR과 C. glutamicum 11TS를 300㎍/㎖의 lysozyme으로 18시간 처리하여 원형질체를 형성하고, 융합시 30%의 PEG 6,000으로 처리하였을 때 가장 높은 3.7×10 exp(-6)의 융합빈도를 나타내었다. 재조합주의 유전적 분석결과 재조합주들은 FMM(Rif^r Sm^r), FA(Rif^r Sm^r arg), FH(Rif^r Sm^r his), FT(Rif^r Sm^r trp), FAH(Rif^r Sm^r arg his), FAT(Rif^r Sm^r arg trp), FAHT(Rif^r Sm^r arg his trp)으로 분류되었다. FAH에 속하는 균주들은 대부분 모균주에 비해 glutamate와 glutamine의 생산성이 월등히 증가하였으며, FAH1의 경우 glutamate 생성에 있어 모균주인 B. flavum 10AHR에 비해 12배, glutamine은 모균주인 C. glutamicum 11TS에 비해 2.6배 정도 생성이 현저히 증가하였다. 재조합주들의 효소활성을 측정해본 결과 glutamate와 glutamine의 생성량은 GDH와 GS의 활성도와 각각 관련이 있음을 알 수 있었다. For interspecific portoplast fusion, Brevibacterium flavum 10AHR(Rif^r arg his) and Corynebacterium glutamicum 11TS(Sm^r trp) were induced by UV and NTG treatment. The protoplast fusion frequency between B. flavum 10AHR and C. glutamicum 11TS was 3.7×10 exp(-6) with the lysozyme treatment(300㎍/㎖) for 18 hrs. Genotypes of recombinants were analized as FMM(Rif^r Sm^r), FA (Rif^r Sm^r arg), FH(Rif^r Sm^r his), FT(Rif^r Sm^r trp), FAH(Rif^r Sm^r arg trp), FAT(Rif^r Sm^r arg trp), and FAHT(Rif^r Sm^r arg his trp). FAH 1 produced 12 fold of glutamate production compared to parental type, B. flavum 10AHR. In glutamine productivity, it produced 2.6 fold to parental type, C. glutamicum 11TS. Production of glutamate or glutamine by recombinants was involved in the specific activities of glutamate dehydrogenase(GDH) and glutamine synthetase(GS), respectively.

This stydy investigates H-shaped houses in 1930s and examines the characters and meanigs of Kim, Jong-Ryang's H-shaped houses as a new trial to urban Hanok of those days. He, who was concerned about the housing problem of Seoul, made an attempt to make various types of dwellings. Among them, this study focuses on Japanese-Korean Style H-shaped houses in Samcheong-dong. As the alternative housing type against other urban Hanok of Seoul in 1930s, the H-shaped houses of Kim, Jong Ryang had characters as follows : 1) H-shaped houses has two special characters. First, the whole space of a single house can be divided into a left region and a right region. Second, it can be divided to a front region and a rear region. In his H-shaped houses, the left/right division was expressed as folding of space-layers in parallel with urban streets. The front/rear division was used as classification of main-living space and sub-living space. 2) KJR's H-shaped Japanese-Korean Style houses were proved to be designed as urban housing against the extreme housing shortage of Seoul in 1930s. 3) His houses however were not accepted broadly as a urban house type because the construction cost of those was higher than an average and the element of Japanese style house was not adapted to Korea. Kim, Jong-Ryang's trial is valuable because it was the rare case of realization of many discourses as defects of existing house type. With more rigorous investigations on KJR's experiment in modern house type, we could understand the housing condition of Seoul in 1930s and modern urban houses more than before.

After the onset of the COVID-19 pandemic, there has been an explosive increase in restaurant meal delivery or takeout. The purpose of this study was to analyze the consumer perception of food safety and its influence on the purchase of delivery or takeout food from restaurants. This study, the 2020 Consumer Behavior Survey for Food (CBSF), was conducted from June 10 to August 21 2020. A total of 6,355 responses were used for the analysis. The results were as follows: First, the differences in consumer perception about food safety were analyzed according to whether they used delivery or takeout. Concern about food safety, satisfaction with dietary habits, and the ability to maintain safe dietary habits were higher in the non-user group. Except for food at home, the perception about food safety at other locations was higher in the user group. Food hazards such as antibiotics were perceived to be safer in the user group. Second, the perception of food safety affecting use of delivery or takeout was analyzed. It was found that the usage of delivery or takeout increased when the perception of the safety of home meal replacement (HMR), delivery or takeout food, and the ability to be informed about the harmful factors of agricultural products increased. The findings of this study may offer the basis for the food and food service industry to consider safety issues seriously and develop strategies to lead to feasible practices. Further, this study also supports the direction of the government toward strengthening the safety of new segments which have shown explosive growth in the COVID-19 era.
