  • Transgenic animal and cell line models which are recently developed and used in toxicology fields combined with molecular biological technique, are powerful tools to study the mechanism of mutation in vivo and in vitro, respectively. Transgenic models, which have exogenous DNA incorporated into their genome, carry recoverable shuttle vector containing reporter genes to assess endogenous effects or alteration in specific genes related to disease processes. The lac I and lac Z gnee most widely used as a mutational target in transgenic systems. The assay is performed by treatment with putative mutagenic agents, isolation of genomic DNA from cells or tissues, exposure the isolated DNA to in vitro packaging extract, plating and sequencing. The results from these processes provide not only mutant frequency as quantitative evaluation but also mutational spectrum as qualitative evaluation of various agents. Therefore we introduce and review the principle, detailed procedure and application of transgenic mutagenesis assay system in toxicology fields especially in mutagenesis and carcinogenesis.

  • One of the chief characteristics of the retrovirus life cycle is the appearance of provirus caused by integration of viral genome into the host cell genome, and its delivery stably to the next generation as a part of host germ line. This stable form is called endogenous retrovirus (ERV) and expressed by exogenous or endogenous factors. HERVs and MuERVs are present in humans and mice correspondingly, and their expressions frequently cause diseases. Several diseases such as cancer, autoimmunity and neurological disorders are related with HERVs. Therefore, various strategies should be established for the development of effective therapies for the suffering patients.

  • Periodontitis is an inflammatory disease of the supportive tissues surrounding the teeth, and is characterized by irreversible destruction of the gingiva, periodontal ligament (PDL), and alveolar bone, which results in the loss of teeth. In the present study, we elucidated the correlation between periodontitis and apelin (APLN), an adipokine and a regulatory peptide, respectively, which are involved in inflammation and bone remodeling. The expression of APLN is negatively correlated with periodontitis progression in gingival tissue. In addition, treatment with TNF-α downregulated the expression of APLN in PDL cells and gingival fibroblasts, indicating the protective role played by APLN against periodontitis progression. The overexpression of APLN or treatment with exogenous APLN suppressed the TNF-α-mediated catabolic gene expression of MMP1, IL6, and PTGS2 in PDL cells. Moreover, the inhibition of the APLNA-PJ axis by ML221, an APJ inhibitor, induced catabolic gene expression in PDL cells. Thus, the results of this study provided evidence to support APLN as a regulatory factor of the inflammatory response during periodontitis.

  • Exogenous lipid pneumonia is a rare disease resulting from the aspiration or inhalation of vegetable, animal, or mineral oils. In Korea, the most frequently implicated agent is squalen, which can be obtained from shark liver oil. Lipid pneumonia by aspiration of the vegetable oil is very rare. We experienced a 77-year-old man with a history of ingestion of green perilla oil. His clinical course was favorable; after exposure to the oil was stopped, the patient's symptoms improved.

  • The rice blast disease caused by of Magnaporthe oryzae is one of the most destructive diseases of rice. By the microarray analysis, we profiled expression changes of genes during conidiation and found out many putative genes that are up-regulated. Among those, we first selected MGG_06399 encoding a dual-specificity tyrosine-regulated protein kinase (DYRK), homologous to YAK1 in yeast. To investigate functional roles of MoYAK1, We made ${\Delta}Moyak1$ mutants by homology dependent gene replacement. The deletion mutant showed a remarkable reduction in conidiation and produced abnormally shaped conidia smaller than those of wild type. The conidia form ${\Delta}Moyak1$ were able to develop a germ tube, but failed to form apppressoria on a hydrophobic coverslip. The ${\Delta}Moyak1$ formed appressria on a hydrophobic cover slip when exogenous cAMP was induced, but the appressoria shape was abnormal. The ${\Delta}Moyak1$ also formed appressoria abberent in shape on onion epidermis and rice sheaths and failed to penetrate the surface of the plants. These data indicate that MoYAK1 is associated with cAMP/PKA pathway and important for conidiation, appressorial formation and pathogenic development in Magnaporthe oryzae. Detailed characterization of MoYAK1 will be presented.

  • The results of the study about comparison of Eastern-Western medicine on the Atopic dermatitis were as follows. 1. Atopic dermatitis is chronic eczematous dermatosis which have severe itching, characteristic eruption, easily occur region and pass on chronic relapsing progress and have family history of Atopic disease and hereditary disposition. 2. Atopic dermatitis assume an remarkable clinical aspect and it's diagnosis depends on family history and clinical symptom. 3. In all cases of Western medical treatment is nothing but a symptomatic treatment because can not find out certainly the cause of Atopic dermatitis. 4. Atopic dermatitis is belong to the category of the 'Naesun(내癬)', 'Taeryumchang(胎斂瘡)', 'Samanpoong(四灣風)' etc. in Oriental medicine. 5. The etiology and pathogenesis of Atopic dermatitis in oriental medicine are congenital defect(稟賦不足), internal accumulation of damp and heat(濕熱內鬱), improper diet(飮食不節), exogenous pathogenic factors(外邪侵襲), etc.. 6. The treatments of Atopic dermatitis in oriental medicine are thought effective clear up heat and remove dampness with febrifugal arld diuretic drug(淸熱利濕), invigorate the spleen to resolve dampness(健脾燥濕), nourish Um and blood to relave dryness(滋陰養血潤燥), etc..

  • Regenerative medicine is a research field that develops methods to restore damaged cell or tissue function by regeneration, repair or replacement. Stem cells are the raw material of the body that is ultimately used from the point of view of regenerative medicine, and stem cell therapy uses cells themselves or their derivatives to promote responses to diseases and dysfunctions, the ultimate goal of regenerative medicine. Stem cell-derived extracellular vesicles (EVs) are recognized as an attractive source because they can enrich exogenous microRNAs (miRNAs) by targeting pathological recipient cells for disease therapy and can overcome the obstacles faced by current cell therapy agents. However, there are some limitations that need to be addressed before using miRNA-enriched EVs derived from stem cells for multiplexed therapeutic targeting in many diseases. Here, we review various roles on miRNA-based stem cell EVs that can induce effective and stable functional improvement of stem cell-derived EVs. In addition, we introduce and review the implications of several miRNA-enriched EV therapies improved by multiplexed targeting in diseases involving the circulatory system and nervous system. This systemic review may offer potential roles for stem cell-derived therapeutics with multiplexed targeting.
