It has been established that P. gymnospora ameliorates amyloid-β-induced neuropathology and has an anticoagulation effect, but this study was designed to estimate its skin-whitening effect and identify its active component. The ingredients of P. gymnospora were extracted with ethanol and its activity was compared with arbutin. First, the P. gymnospora extract was observed to inhibit tyrosinase activity in a dose-dependent manner, tyrosinase being the rate-limiting enzyme of melanin synthesis. Notably, where 200 μM of arbutin inhibited tyrosinase activity by 58.1%, P. gymnospora extract (0.5%) achieved 76.7%. The P. gymnospora extract also significantly reduced α-melanocyte-stimulating hormone-induced TRP-1 and TRP-2 mRNA expression. In addition, it significantly inhibited melanin synthesis in B16F10 melanoma cells. We identified the 0.66% fucosterol content that inhibited melanin synthesis as comparable to that of arbutin. Additionally, we tested the potential cytotoxicity of P. gymnospora by MTT and LDH release assay and found that the extract significantly reduced LDH release in CCD-986sk cells. These results indicate that P. gymnospora extract could be a potential active ingredient of cosmetics with a skinwhitening effect.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":"14 1","pages":"598-605"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87511779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental animals were divided two groups as follows; water administered group (CON) and Allium cepa administered group (ACE). The ACE group showed a slightly increases in the number of erythrocytes (RBC), hemoglobin (HGB), hematocrit (Hct) levels compared to the control group (p< 0.05). Hemoglobin, monocyte, lymphocyte and neutrophil had no significant change (p>0.05) in ACE group and control group. The analysis of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels showed a significant decrease in ACE group compared to the control group (p<0.05). The blood glucose, total protein, HDL-cholesterol were slightly high in ACE group, while triglyceride, total cholesterol levels were lower in ACE group compared to the control group (p<0.05). The levels of cytokines (interluekin-1α (IL-1α), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon-γ (INF-γ), interleukin-18 (IL-18), interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF)) involved in immunity and inflammation in liver tissue and blood have all been confirmed to be within normal range.

In this study, SNP primers developed from five pollination-constant astringent (PCA) persimmons native to Korea were applied to discriminate between cultivars and verify their usability. The polymerase chain reactions of 19 SNP primers developed by Jung et al. were checked, with 11 primers finally selected. The other eight were very difficult to analyze in the agarose gel electrophoresis and QIAxcel Advanced System used in this experiment and were therefore excluded. The 11 SNP primers were applied through first and second verification to 76 cultivars and collection lines including 20 pollination-variant non-astringent (PVNA), 30 pollination-constant non-astringent (PCNA), 20 PCA, and six pollination-variant astringent (PVA). Of these, 38 were indistinguishable (eight PVNA, 18 PCNA, nine PCA, and three PVA). However, the results of applying the 11 SNP primers to new sweet persimmon cultivars, namely Gamnuri, Dannuri, Hongchoo, Jamisi, and Migamjosaeng, showed that they have the potential to be used as a unique marker for simultaneously determining between them.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":"16 2 1","pages":"614-624"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83872457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this, stem-cell therapies are emerging as a promising strategy for cardiovascular regeneration. Endothelial progenitor cells (EPCs) have high potential to proliferate and differentiate into endothelial cells for vascularization and tissue regeneration, and several clinical trials have explored EPC function in tissue repair in relation to clinical safety and improving cardiac function. Consequently, EPC has been suggested as a feasible stem-cell therapy. However, autologous EPC transplantation in cardiovascular disease patients is restricted by risk factors such as age, smoking status, and hypertension that lead to reduced bioactivity in the EPCs. New approaches for improving EPC function and stem-cell efficacy have therefore been suggested, including cell priming, organoid culture systems, and enhancing transplantation efficiency through 3D bioprinting methods. In this review, we provide a comprehensive understanding of EPC characteristics, therapeutic approaches, and the current state of clinical research into EPCs as stem-cell therapy for cardiovascular disease.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":"39 1","pages":"651-659"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80717577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BCNU 106. Among the 100 up-expressed products, 50 complementary DNA fragments were confirmed to express repeatedly; these were cloned and then sequenced. Blast analysis revealed that toluene stimulated an adaptive increase in the gene expression level in association with transcriptions such as LysR family of transcriptional regulators and RNA polymerase factor sigma-32. The expression of catalase and Mn2+/Fe2+ transporter genes functionally associated with inorganic ion transport and metabolism increased, and the increased expression of type IV pilus assembly PilZ and multi-sensor signal transduction histidine kinase genes, functionally categorized into signal transduction and mechanisms, was also demonstrated under toluene stress. The gene expression level of beta-hexosaminidase in association with carbohydrate transport and metabolism increased, and those of DNA polymerase III subunit epsilon, DNA-3-methyladenine glycosylase II, DEAD/DEAH box helicase domain-containing protein, and ABC transporter also increased after exposure to toluene in DNA replication, recombination, and repair, and even in defense mechanism. In particular, the RNAs corresponding to the ABC transporter, Mn2+/Fe2+ transporter, and the β-hexosaminidase gene were confirmed to be markedly induced in the presence of 10% toluene. Thus, defense mechanism, cellular ion homeostasis, and biofilm formation were shown as essential for toluene tolerance in Pseudomonas sp.
