[Ab] Abstract:The development and utilization of biomass resources could contribute to explore novel materials for long-term sustainable energy storage and environmental applications, reduce environmental impacts, and meet the urgent need for green and sustainable development strategies. Herein, a bimetallic metal-phenolic networks (MPN) was applied to incorporate different metallic element species into cattle skin and fabricate collagen fiber-derived complex oxide nanofibers using natural polyphenols (Myrica tannins). Direct thermal transition of these biomass-MPN composites generates hierarchically porous nanofibers possessing micro- and mesoporous architectures along with a well-preserved macroscopic structure. The pore system and complex oxide composition provide excellent photocatalytic performance. This low-cost, simple and readily scalable MPN-based approach provides a straightforward route to synthesize nanostructured materials directly from biomass, which could play important roles in a wide range of potential applications.

[Ab] Abstract:OBJECTIVE: Currently, the cosmetic and medical industries are paying considerable attention to solve or prevent skin damage or diseases, such as hyperpigmentation and oxidation and free radical damage. In this study, the effective compounds in Myrica rubra fruit were extracted and studied the biological effects of these M. rubra fruit extracts. METHODS: In this study, we extracted M. rubra fruit using solutions with various ratios of water to ethanol (100:0, 50:50, 5:95) and studied the anti-melanogenesis, anti-oxidation and radical scavenging effects of these M. rubra fruit extracts on two melanoma cell lines: mouse melanoma (B16-F0) and human melanoma (A2058). The cytotoxicity, melanin synthesis, mushroom and cellular tyrosinase activities, enzyme kinetics, melanogenesis-related gene expression, melanogenesis-related protein secretion, radical DPPH scavenging activity and ROS inhibition after treatment with M. rubra fruit extracts were determined. RESULTS: The results showed that the water extract of M. rubra fruit was less cytotoxic to the melanoma cell lines, effectively inhibited melanin synthesis and tyrosinase activity and down-regulated the gene expression and protein secretion of MITF and TRP-1. In addition, the M. rubra fruit extracts also showed the abilities to scavenge DPPH free radicals and suppress ROS production. Finally, the effective compounds in the water extract were Myricetin-O-deoxyhexoside, Quercetin-O-deoxyhexoside, and Kaempferol-O-hexoside determined by LC/MS/MS assay. CONCLUSION: Overall, the water extract of M. rubra fruit is a safe and effective melanin inhibitor and anti-oxidant and can be applied widely in the fields of cosmetics and medicine.

[Ti] Title:Host-Tree Selection by the Invasive Argentine Ant (Hymenoptera: Formicidae) in Relation to Honeydew-Producing Insects.

[Ab] Abstract:The Argentine ant, Linepithema humile (Mayr; Hymenoptera: Formicidae), is one of the world's most hazardous invasive species, and thus its eradication from Japan is important. Physical and chemical controls can be expensive and cause strong adverse effects on local terrestrial ecosystems regardless of their high efficacy. Here, presence/absence of host-tree selection by Argentine ants was investigated to understand the ant-honeydew-producing insects interactions in order to develop new cultural controls compatible with biodiversity conservation. Abundance of Argentine ants and their tree utilization ratio was measured among dominant roadside trees (Cinnamomum camphora, Myrica rubra, Nerium indicum, Rhaphiolepis indica var. umbellata, Juniperus chinensis var. kaizuka) in two areas around Kobe, Japan. Almost all ants collected were Argentine ants suggesting that native ants would have been competitively excluded. Tree utilization of Argentine ants clearly differed among host trees. Abundance of both Argentine ants and honeydew-producing insects and tree utilization rate of the ants were significantly lower in especially C. camphora and J. chinensis. Few Argentine ants were observed trailing on C. camphora, J. Chinensis, and N. indicum, most probably due to low abundance of honeydew-producing insects on these trees with the toxic and repellent chemical components. On the other hand, high abundance of both Argentine ants and homopterans were found in M. rubra and especially R. indica. We suggest that reductions of R. indica and M. rubra would lead to a decrease in abundance of honeydew-producing insects, and thus effectively control populations of Argentine ants. At the same time, planting of C. camphora, J. Chinensis, and N. indicum may also play a role in restraint efficacy against invasion of the invasive ants.

[Ab] Abstract:Cancer stem cells (CSCs) represent a small population of cancer cells characterized by self-renewal ability, tumorigenesis and drug resistance. Ovarian cancer is one of the leading causes of death related to the female reproductive system in Western countries and has been evaluated as a type of CSC-related cancer in recent years. Natural products have attracted great attention in cancer treatment in recent years due to drug resistance and a high relapse rate of ovarian cancer. Chinese bayberry leaf proanthocyanidins (BLPs) contain epigallocatechin-3-O-gallate as their terminal and major extension units, which is quite unusual in the plant kingdom. BLPs showed strong antioxidant and antiproliferative abilities in previous studies. In the present study, chemotherapy-resistant OVCAR-3 spheroid (SP) cells were obtained by sphere culturing and exhibited CSC-like properties by showing a higher ALDH population and higher expression of stemness-related proteins. BLPs exhibited inhibitory effects on the growth and CSC characteristics of OVCAR-3 SP cells by showing decreased cell viability, sphere and colony formation ability, ALDH population and expression of stemness-related proteins. BLPs also targeted the Wnt/ß-catenin pathway by reducing the expression of ß-catenin, cyclin D1 and c-Myc and thus inhibited the self-renewal ability of OVCAR-3 SP cells. Furthermore, BLPs also induced G1 cell cycle arrest in OVCAR-3 SP cells. Taken together, these findings suggested that BLPs may be an important agent in the development of therapeutics for ovarian cancer patients.

[Ab] Abstract:Myricetin is a flavonoids compound extracted from edible myrica rubra. We aimed to evaluate the efficacy of Myricetin on colonic chronic inflammation and inflammation-driven tumorigenesis in mice. Myricetin was administrated by gavage for 4 consecutive weeks. Mice were sacrificed and the number of colonic polyps was counted. Myricetin significantly inhibited AOM/DSS-induced colitis and colorectal tumorigenesis. Myricetin prevented the incidence of colorectal tumorigenesis and reduced the size of colorectal polyps. Histopathologic analysis showed that Myricetin could attenuate the degree of colonic inflammation and colorectal tumorigenesis. Further analysis showed that Myricetin strongly reduced the levels of inflammatory factors TNF-α, IL-1ß, IL-6, NF-κB, p-NF-κB, cyclooxygenase-2 (COX-2), PCNA and Cyclin D1 in the colonic tissues as analyzed by the assays of immunohistochemical staining, Western blotting and Q-RT-PCR. Our results demonstrated that Myricetin possesses the biological activities of chemoprevention colonic chronic inflammation and inflammation-driven tumorigenesis. We suggest that Myricetin could be developed as a promising chemopreventive drug for reducing the risk of colorectal cancer.

[Ab] Abstract:Increased expression of adhesion molecules is thought to serve an important role in the pathogenesis of atherosclerosis. Myricitrin, a bioactive compound of Myrica cerifera, has been demonstrated to exhibit anti­atherogenic effects. However, the effect of myricitrin on the expression of adhesion molecules in vascular smooth muscle cells (VSMCs) remains unknown. Therefore, the aim of the present study was to evaluate the inhibitory effects of myricitrin on tumor necrosis factor­α (TNF­α)­induced expression of adhesion molecules in VSMCs in vitro. The results revealed that myricitrin inhibited the adhesion of human THP­1 monocyte cells to TNF­α­stimulated mouse MOVAS­1 VSMC cells, and reduced the expression of adhesion molecules in TNF­α­stimulated MOVAS­1 cells. In addition, myricitrin significantly inhibited the TNF­α­induced expression of nuclear factor (NF)­κB p65, and prevented the TNF­α­induced degradation of nuclear factor of κ light chain enhancer in B­cells inhibitor α. Furthermore, myricitrin inhibited the production of intracellular reactive oxygen species in TNF­α­stimulated MOVAS­1 cells. In conclusion, the results of the present study indicated that myricitrin inhibits the expression of vascular cell adhesion protein­1 and intercellular adhesion molecule­1 in TNF­α­stimulated MOVAS­1 cells potentially via the NF­κB signaling pathway. Therefore, myricitrin may be an effective pharmacological agent for the prevention or treatment of atherosclerosis.

[Ab] Abstract:The anti-obesity effects of different proanthocyanidin extracts (PE) from Chinese bayberry (Myrica rubra Sieb.et Zucc.) leaves were evaluated in a high-fat (HF) diet-induced obese rat model. The leaves of Chinese bayberry (LCB), a non-desaccharified proanthocyanidin extract (NDPE), and a desaccharified proanthocyanidin extract (DPE) were compared with orlistat, a conventional anti-obesity drug used as a positive control. The rats from all of the PE-treated groups showed obvious weight loss, with the greatest weight loss in the DPE group (P < 0.05). Compared to the HF group, almost all of the PE-treated groups showed significantly reduced levels of serum TC, TG, AST, ALT, ALP, LDL-C, ADP and a LEP/ADP ratio, and increased levels of HDL-C and LEP. Furthermore, the expression levels of SIRT1, PPAR-γ, C/EBP-α, BMP4 and UCP1 were investigated in the liver, kidney, epididymis and abdominal adipose tissue. Compared to the HF group, PPAR-γ and C/EBP-α levels were significantly reduced and SIRT1, BMP4 and UCP1 levels were significantly upregulated in the DPE-treated group. Our results suggested that PE exerted its anti-obesity effects by upregulating the expression of SIRT1, thus inducing the deacetylation of PPAR-γ and downregulating the expression of C/EBP-α, and also upregulating the expression of BMP4 to boost the levels of brown fat.

[Ab] Abstract:The chemical profile of (a native species in China) leaf extract was investigated by UPLC-PDA-HRMS, and the neuroprotective activity of two characteristic constituents, myricanol and myricetrin, was evaluated with N2a cells using H2O2-inducedoxidative challenge through a series of methods, e.g., MTT assay, ROS assay and [Ca ]i assay. Among the 188 constituents detected in the extract of leaf, 116 were identified definitely or tentatively by the comprehensive utilization of precise molecular weight and abundant multistage fragmentation information obtained by quadrupole orbitrap mass spectrometry. In addition, 14 potential new compounds were reported for the first time. This work established an example for the research of microconstituents in a complex analyte and revealed that suppression of H2O2-induced cytotoxicity in N2a cells was achieved by the pretreatment with myricanol. The evidence suggested myricanol may potentially serve as a remedy for prevention and therapy of neurodegenerative diseases induced by oxidative stress.

[Ab] Abstract:ß-caryophyllene oxide (CAO), α-humulene (HUM), trans-nerolidol (NER) and valencene (VAL) are constituents of the essential oil of (MEO), which has significant antiproliferative effect in various cancer cell lines. In the present study, we compared the antiproliferative effect of these sesquiterpenes alone and in combination with the cytostatic drug doxorubicin (DOX) in cancer cell lines with different sensitivity to DOX. Two ovarian cancer cell lines (sensitive A2780 and partly resistant SKOV3) and two lymphoblast cancer cell lines (sensitive CCRF/CEM and completely resistant CEM/ADR) were used. The observed effects varied among sesquiterpenes and also differed in individual cell lines, with only VAL being effective in all the cell lines. A strong synergism of DOX with NER was found in the A2780 cells, while DOX acted synergistically with HUM and CAO in the SKOV3 cells. In the CCRF/CEM cells, a synergism of DOX with CAO and NER was observed. In resistant CEM/ADR cells, sesquiterpenes did not increase DOX efficacy, although they significantly increased accumulation of DOX (up to 10-times) and rhodamine-123 (substrate of efflux transporter ABCB1) within cancer cells. In conclusion, the tested sesquiterpenes were able to improve DOX efficacy in the sensitive and partly resistant cancer cells, but not in cells completely resistant to DOX.

[Ti] Title:Prodelphinidins isolated from Chinese bayberry leaves induces apoptosis via the p53-dependent signaling pathways in OVCAR-3 human ovarian cancer cells.

[Ab] Abstract:Chinese bayberry leaves are rich in prodelphinidins. Since the isolation and purification of prodelphinidins is difficult, the association between the degree of prodelphinidin polymerization and their anti-carcinogenic activity remains ambiguous. The cytotoxic and apoptotic activities of prodelphinidin Chinese bayberry leaf extracts (PCBLs), oligomeric proanthocyanidins (OPAs) and polymeric proanthocyanidins (PPAs), isolated by normal-phase preparative high-performance liquid chromatography were investigated in OVCAR-3 human ovarian cancer cells. The PCBLs, OPAs and PPAs inhibited cancer cell growth and induced apoptosis via the caspase-dependent pathway. Apoptosis was triggered through the intrinsic pathway by upregulating the expression of several B-cell lymphoma-2 (Bcl-2) family proapoptotic proteins, including p53-upregulated modulator of apoptosis (PUMA), Bcl-2-associated X protein and Bcl-2-associated agonist of cell death, and by downregulating the antiapoptotic protein Bcl-extra large. Apoptosis was also triggered through the extrinsic pathway via the upregulation of death receptor 5 (DR5) and Fas expression. In addition, OPAs and PPAs induced caspase-dependent apoptosis at least partially through the inhibition of the protein kinase B signaling pathway. The knockdown of p53 by specific small interfering RNA resulted in the depletion of p53, and inhibited the OPA and PPA treatment-induced increases in p53, which led to a decrease in the expression of p21, DR5, Fas, PUMA and phosphatase and tensin homolog proteins. These observations demonstrate that p53 is a mediator of OPA and PPA-induced apoptosis in OVCAR-3 cells. The PPAs exhibited stronger anti-proliferative and pro-apoptotic activities compared with OPAs and PCBLs. These results suggest that PCBLs, OPAs and PPAs may be useful for the treatment of ovarian cancer.
