  • Spatial and temporal expression of pathogenesis-related (PR) gene and proteins has been recognized as inducible defense response in pepper plants. Gene expression and/or protein accumulation of PR-1, $\beta-1,3-glucanase$ and chitinase was predominantly found in pepper plants during the inoculations by Xanthomonas campestris pv. vesicatoria, Phytophthora capsici and Colletotrichum coccodes. PR-1 and chitinase genes were also induced in pepper plants in response to environmental stresses, such as high salinity and drought. PR-1 and chitinase gene expressions by biotic and abiotic stresses were regulated by their own promoter regions containing several stress-related cis-acting elements. Overexpression of pepper PR-1 or chitinase genes in heterogeneous transgenic plants showed enhanced disease resistance as well as environmental stress tolerances. In this review, we focused on the putative function of pepper PR-1, $\beta-1,3-glucanase$ and chitinase proteins and/or genes at the biochemical, molecular and cytological aspects.

  • The mammalian unfolded protein response (UPR) protects the cell. against the stress of unfolded or misfolded proteins in the endoplasmic reticulum (ER). It has recently demonstrated that IRE1, PERK, ATF6, and X-box protein 1 (XBP-l) directly or indirectly participate in this process. Upon accumulation of unfolded/misfolded proteins in the ER lumen, release of BiP from Ire1p permits dimerization and autophosphorylation to activate its kinase and endoribonulease activities to initiate XBP-1 mRNA splicing. Spliced XBP-1 mRNA removed middle part of 23 bp and encodes a potent transcription factor, XBP-l protein that binds to the unfolded protein response element (UPRE) or endoplasmic reticulum stress element (ERSE) sequence of many UPR target genes and produces several kind of ER chaperones. In this study, we described both the result and the detailed experimental procedures of XBP-1 mRNA splicing induced by ER stress, this result might help to elucidate the roles of the UPR and early diagnosis in a number of human diseases involving endoplasmic reticulum storage disease (ERSD).

  • Purpose: Despite well-known benefits of walking on cardiovascular health, no structured walking exercise program has been formally tested on elderly Korean immigrants (EKIs). This pilot randomized controlled trial study assessed the effect of a walking program on walking behavior (pedometer steps count), stress (cortisol), depressive symptoms (CESD-10), and cardiovascular disease biomarkers (hs-CRP and fibrinogen) via venipuncture in EKIs. Methods: Seventy EKIs recruited from a Korean community were randomly assigned to a 12-week walking group or control group in a 3:2 ratio. The working program included a pedometer, buddy, monthly coffee card, weekly call for goal setting, and physical activity consultation. Walking group EKIs maintained the Centers for Disease Control and Prevention recommended exercise guidelines and good mental health status over 12 weeks. Results: There was no significant difference in the outcomes between control and walking groups. Conclusion: Social networking with Koreans in the senior center and church from a well-established Korean community might have positive effects on mental health.

  • Lysine-specific demethylase 1 (LSD1) is an epigenetic regulator that modulates the chromatin status, contributing to gene activation or repression. The post-translational modification of LSD1 is critical for the regulation of many of its biological processes. Phosphorylation of serine 112 of LSD1 by protein kinase C alpha (PKCα) is crucial for regulating inflammation, but its physiological significance is not fully understood. This study aimed to investigate the role of Lsd1-S112A, a phosphorylation defective mutant, in the cigarette smoke extract/LPS-induced chronic obstructive pulmonary disease (COPD) model using Lsd1SA/SA mice and to explore the potential mechanism underpinning the development of COPD. We found that Lsd1SA/SA mice exhibited increased susceptibility to CSE/LPS-induced COPD, including high inflammatory cell influx into the bronchoalveolar lavage fluid and airspace enlargement. Additionally, the high gene expression associated with the inflammatory response and oxidative stress was observed in cells and mice containing Lsd1-S112A. Similar results were obtained from the mouse embryonic fibroblasts exposed to a PKCα inhibitor, Go6976. Thus, the lack of LSD1 phosphorylation exacerbates CSE/LPS-induced COPD by elevating inflammation and oxidative stress.

  • The endoplasmic reticulum (ER) is crucial for protein synthesis, transport, and folding, as well as calcium storage, lipid and steroid synthesis, and carbohydrate metabolism. Endoplasmic reticulum stress (ERS) occurs when misfolded or unfolded proteins accumulate in the ER lumen due to increased protein secretion or impaired folding. While the role of ERS in disease pathogenesis has been widely studied, most research has focused on extraoral diseases, leaving the role of ERS in intraoral diseases unclear. This review examines the role of ERS in oral diseases and oral fibrosis pathogenesis. A systematic search of literature through July 2023 was conducted in the MEDLINE database (via PubMed) using specific terms related to ERS, oral diseases, and fibrosis. The findings were summarized in both table and narrative form. Emerging evidence indicates that ERS significantly contributes to the pathogenesis of oral diseases and fibrosis. ERS-induced dysregulation of protein folding and the unfolded protein response can lead to cellular dysfunction and inflammation in oral tissues. Understanding the relationship between ERS and oral disease pathogenesis could offer new therapeutic targets for managing oral health and fibrosis-related complications.

  • Although there has been a considerable research in psychoneuroendocrinology, particularly in relation to the biology of mood disorders, there has been a paucity of research regarding the effects of psychological factors on endocrine diseases. Of the existing literature, the most research is focused on diabetes mellitus, graves' disease. Especially diabetes appears to be the only endocrine disease that has been the focus of recent research studies. Most of the studies had retrospective designs or several methodological flaw. There has been no consistent results demonstrating that psychological factors affect the onset of diabetes mellitus. Several studies have suggested that psychological factors affect the course of diabetes. A small number of studies showed some evidence that psychological stress was associated with changes in glucose regulation in a subset of diabetic patients. There was also evidence to suggest that some temperament and coping skill influence glycemic control in child, adolescent diabetics. Studies of behavioral or psychosocial intervention on diabetic control have been small and have produced mixed results. There was a few controlled study suggested that stressful life events might be a causal role in Cushing's disease and Graves'disease, but there is no presently sufficient evidence to suggest that psychological factors affect the onset and the course of Cushing's disease and Graves' disease. In future, there is need for a well-designed biopsychosocial research with prospective designs, well defined patient population and control groups to study the relationship between psychological factors and endocrine diseases.

  • Objectives: The objective of the study was to investigate the related factors of preventive behavior experience toward dental caries and periodontal disease in Korean adolescents. Methods: The study subjects were 72,060 adolescents in 800 schools who completed 2014 Korean Youth Risk Behavior Web-based survey. Dependent variables included general characteristics of the subjects, oral health behavior, and oral disease experience. The experience rate of sealant and scaling showed the prevention behavior of dental caries and periodontal disease. Data were analyzed by IBM SPSS statistics 20.0. Results: The experience rate of sealant accounted for 26.9%. The experience of sealant was related with gender, school, maternal education level, economic status, vigorous physical activity, smoking, usual stress, fruit consumption, milk consumption, soda consumption, snack consumption, tooth brushing, oral health education experience, periodontal bleeding and pain, mucosal disorders, and bad breath. The experience rate of scaling was 22.6%. The experience of scaling was related with gender, school, city division, learning achievement, maternal education level, economic status, residential type, vigorous physical activity, usual stress, fruit consumption, milk consumption, tooth brushing, oral health education experience, periodontal bleeding and pain, mucosal disorders, and bad breath. Conclusions: To expand preventive oral health behavior in the adolescents, it is necessary to support the systematic policy making and monetary establishment in the future.

  • Maesil (Prunus mume Siebold & Zucc.), a member of the genus Rosaceae, has been reported to have antioxidative effects, as well as anticancer influence in many cancer lines. Thus, this present study was designed to investigate the inhibitory effect of fermented Maesil with probiotics against 7,12-dimethylbenz[a]anthracene (DMBA), 12-O-tetradecanoyl phorbol 13-acetate (TPA)-induced mouse skin carcinogenesis via its antioxidative potential. Mice were fed a diet containing fermented Maesil, containing either 1% (1% FM fed group) or 2% (2% FM fed group) along with probiotics following DMBA and TPA exposure. Continuous ingestion of the experimental feed markedly inhibited skin carcinogenesis, as evidenced by a marked decrease in papilloma numbers and epidermal hyperplasia as well as cellular proliferation and the percentage of proliferating-cell nuclear antigen positive cells. Also, the FM fed group showed an increase of total antioxidant capacity as well as an increased level of phase II detoxifying enzymes such as superoxide dismutase, concurrent with a decreased lipid peroxidation activity level. Taken together, these results suggest that fermented Maesil has the ability to suppress the development of DMBA-TPA induced skin carcinogenesis, via the reduction of lipid peroxidation, enhancing total antioxidant capacity and phase II detoxifying enzyme.
