Background: Genetic alterations have been identified in melanomas according to different levels of sun exposure. Whereas the conventional morphology-based classification provides a clue for tumor growth and prognosis, the new classification by genetic alterations offers a basis for targeted therapy. Objective: The purpose of this study is to demonstrate the biological behavior of melanoma subtypes and compare the two classifications in the Korean population. Methods: A retrospective chart review was performed on patients found to have malignant melanoma in Severance Hospital from 2005 to 2012. Age, sex, location of the tumor, histologic subtype, tumor depth, ulceration, lymph node invasion, visceral organ metastasis, and overall survival were evaluated. Results: Of the 206 cases, the most common type was acral melanoma (n=94, 45.6%), followed by nonchronic sun damage-induced melanoma (n=43, 20.9%), and mucosal melanoma (n=40, 19.4%). Twenty-one patients (10.2%) had the chronic sun-damaged type, whereas eight patients (3.9%) had tumors of unknown primary origin. Lentigo maligna melanoma was newly classified as the chronic sun-damaged type, and acral lentiginous melanoma as the acral type. More than half of the superficial spreading melanomas were newly grouped as nonchronic sun-damaged melanomas, whereas nodular melanoma was rather evenly distributed. Conclusion: The distribution of melanomas was largely similar in both the morphology-based and sun exposure-based classifications, and in both classifications, mucosal melanoma had the worst 5-year survival owing to its tumor thickness and advanced stage at the time of diagnosis.

The purpose of this study is to understand interrelationships among young entrepreneurs` growth factors, entrepreneurial capability and entrepreneurial intentions, targeting the students who major in culinary and foodservice. Based on total 327 samples obtained from the empirical research, this study reviewed reliability and fitness of the research model and verified total 2 hypotheses with the Amos program. The proposed model provided an adequate fit for the data, x2=495.217 (p<.001), df=231, CMIN/DF 2.144, GFI .902, AGFI .878, NFI .911, CFI .954, RMSEA .067. The SEM results showed that the young entrepreneurs` growth factors such as policy support(β =.457, p<.001), skills & knowledge(β=.244, p<.01), role model(β= .242, p<.05) in order had significantly positive effects on entrepreneurial capability, and entrepreneurial capability(β= .787, p<.001) had positive(+) effects on entrepreneurial intentions, verifying organic causal relationships among the growth factors, entrepreneurial capability, and entrepreneurial capability. These study results showed that there should be more systematic supports to encourage young entrepreneurs. Limitations and further research directions are also discussed.

Background: Melanomas at different levels of sun exposure are found to have genetic alterations such as BRAF, NRAS, KIT, and GNAQ/11 mutations. Objectives: We designed this study to analyze the mutation status of primary tumors in Korean melanoma patients and to investigate the discordance rate between the primary tumors and the paired metastatic samples. Methods: Patients diagnosed with malignant melanoma from 2005 to 2012, 188 in number, at Yonsei University Health System, were enrolled for this study. Results: The most common type was acral type (n=89, 47.3%) followed by non-chronic sun damage induced type (Non-CSD type) (n=32, 17%) and mucosal type (n=31, 16.5%). The overall incidence of somatic mutation was 17.6% in the BRAF gene, 12.6% in NRAS, and KIT amplification was 28.6%. GNAQ/11 mutation in the uveal type was 66.6%. Of the non-CSD type, 41.9% had the BRAF mutation while 35.8% of the acral type had KIT amplification. Among the 43 patients who had both primary tumor and metastatic tissues, 22 patients (51.2%) showed heterogeneity, regardless of age, gender, subtype and stage. In our study, heterogeneity of the paired tumors did not affect the overall survival. Conclusion: In conclusion, the characteristics of the mutation between Korean and Caucasian melanomas are similar, but the proportion of the subtypes is distinguishable. About half of the Korean melanoma patients showed significant genetic heterogeneity which did not affect the overall survival in our study.

<P>Members of the inhibitors of differentiation (Id) family of helix-loop-helix (HLH) proteins are known to play important roles in the proliferation and differentiation of many cell types. Thyroid-stimulating hormone (TSH) regulates proliferation and differentiation by activating TSH receptor (TSHR) in thyrocytes. In this study, we found that Id2, one of the Id family proteins, is a major target for regulation by TSH in FRTL-5 thyroid cells. TSH rapidly increases the Id2 mRNA level in FRTL-5 thyroid cells but the Id2 protein showed biphasic regulatory patterns, being transiently reduced and subsequently induced by TSH treatment. Transient reduction of Id2 protein was noted within 2 hr of TSH treatment and was mediated by proteasomal degradation. Moreover, reduced Id2 expression correlated with the activity of the phosphatidylinositol 3 kinase pathway, which is activated by TSH. Although TSH increases the activity of the Id2 promoter, TSH-induced activation of this promoter was independent of c-Myc. Id2 did not alter TTF-1- and Pax-8-mediated effects on the regulation of the Tg promoter. Thus, in summary, we found that TSH regulates Id2 expression, but that Id2 does not alter the expression of thyroid-specific genes, such as Tg, in FRTL-5 thyroid cells.</P>

N/A Objectives: The cat fur allergen used in skin prick test was known to be contaminated with housedust mites. So we intended to evaluate the clinical importance of cat fur as a causative allergen in patients with allergic diseases. Methods: We performed skin prick tests with cat allergen of Torii company(Japan), Bencard company (England) and home made extracts in 387 patients, We detected specific IgE by 3M FAST-plus and ELISA method using home made cat fur allergen, developed at this class. To characterize the allergenic components, cat fur extracts were fractionated by 12 % sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE) and then transferred onto nitrocellulose membrane and probed with sera of cat fur sensitive patients Results: 1) Out of 387 patients, 77(19.9%) showed more than 1+results on skin prick test. There were no significant differences in the rates of positive results ac- cording to the allergic diseases, but the age groups were correlated with the positive results(younger than 30: 34.5%, between 30 and 50: 14.4%, older than 50: 6.8%). 2) Cat ELISA showed specific inhibition to cat fur allergen and Cat ELISA inhibition test revealed the linear dose response curve on the added amounts of cat allergn into pooled sera. 67.7% out of Torii cat fur sensitive patients(A/H ratio≥1) showed positive results in Cat ELISA for specific IgE antibody. 3) Cat fur extracts showed 15 protein bands by SDS-PAGE, then they were transferred onto nitrocellulose membrane and probed with sera of 16 cat-fur sensitive patients, one sera pool of patients with RAST class 3, and three negative controls and with biotin-conjugated anti IgE-avidin peroxidase. Six IgE binding protein bands were detected at 94, 73, 56, 44, 28 and 21 kilodalton of molecular weight. Out of six IgE binding bands, MW 21KD concerned as major cat allergen, Fel d 1, were noted in five sera(31.3% ). Conclusion: It is suggested that cat fur can be regarded as an important allergenic fur and that we need further studies to st.andardize cat antigens for in vivo and in vitro tests.

BET inhibitor, as an epigenetic regulator inhibitor, reduces the expression of oncogenes such as Myc and Bcl-2, which affects cancer growth and development. However, it has modest activity because of the narrow therapeutic index. Therefore, combination therapy is necessary to increase the anti-tumor effect. Paclitaxel, an anti-mitotic inhibitor, is used as second-line therapy for gastric cancer (GC) as a monotherapy or combination. In this study, we performed RNA sequencing of GC cells treated with iBET-151 and/or paclitaxel to identify the differentially expressed genes associated with possible mechanisms of synergistic effect. We also performed Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses to determine the most enriched terms and pathways of upregulated and downregulated genes. We found 460 genes in which iBET-151 and paclitaxel combination treatment changed more than single-treatment or no-treatment. Thus, additional functional studies are needed, but our results provide the first evidence of the synergistic effect between iBET-151 and paclitaxel in regulating the transcriptome of GC cells.

This study was performed to investigate the effects of pine pollen and horseradish. which were known as antimicrobial materials, on the fermentation of Kimchi. The physicochemical and microbial changes of Kimchi were investigated during period 30-days at 10t. Even though Kimchi added pine pollen or horseradish powder were sustained the higher pH and lower acidity after 10 days, it delayed only I- 2 more days to reach optimal value of Kimchi fermentation in experimental groups than control. The horseradish powder showed the antimicrobial effect of Kimchi at initial stage, but thereafter that effect of pine pollen or horseradish were not significant. Therefore the addition of pine pollen or horseradish powder to Kimchi is not sufficiently effective for extension of shelf-life of Kimchi.
