Abstract
As one of the dominant bacteria in the ocean, Vibrio play important roles in maintaining the aquatic ecosystem. In this study, we studied the phylogenetic relationships of 32 Vibrio based on the 16S rRNA genes sequences and utilized substrate immersing zymography method to detect the trend of protease production and components of multiprotease system of Vibrio extracellular proteases. The result showed that different extracellular proteolytic profiles among various Vibrio strains demonstrated a large interspecific variation, and for strains from the same environments, the closer the evolutionary relationship of them, the more similar their zymograms were. In addition, these proteases displayed very different hydrolysis abilities to casein and gelatin. Moreover, the results of the inhibitor-substrate immersing zymography indicated that the proteases secreted by marine Vibrio mostly belonged to serine proteases or metalloproteases. These results implied that combined taxonomic information of the Vibrios with their extracellular protease zymograms maybe contributed to the study of the classification, phylogeny and pathogenic mechanism of Vibrio, and can serve as a theoretical basis for controlling the pathogenic Vibrio disease as well as exploiting proteases. More importantly, we can also eliminate many similar strains by this way, thus can greatly reduce the workload of the experiments for us.

The Lipid Mediator Resolvin D1 Reduces the Skin Inflammation and Oxidative Stress Induced by UV Irradiation in Hairless Mice. Front Pharmacol 2018; 9:1242.

Abstract
UV irradiation-induced oxidative stress and inflammation contribute to the development of skin diseases. Therefore, targeting oxidative stress and inflammation might contribute to reduce skin diseases. Resolvin D1 (RvD1) is a bioactive metabolite generated during inflammation to actively orchestrate the resolution of inflammation. However, the therapeutic potential of RvD1 in UVB skin inflammation remains undetermined, which was, therefore, the aim of the present study. The intraperitoneal treatment with RvD1 (3-100 ng/mouse) reduced UVB irradiation-induced skin edema, myeloperoxidase activity, matrix metalloproteinase 9 activity, and reduced glutathione depletion with consistent effects observed with the dose of 30 ng/mouse, which was selected to the following experiments. RvD1 inhibited UVB reduction of catalase activity, and hydroperoxide formation, superoxide anion production, and gp91phox mRNA expression. RvD1 also increased the Nrf2 and its downstream targets NQO1 and HO-1 mRNA expression. Regarding cytokines, RvD1 inhibited UVB-induced production of IL-1β, IL-6, IL-33, TNF-α, TGF-β, and IL-10. These immuno-biochemical alterations by RvD1 treatment had as consequence the reduction of UVB-induced epidermal thickness, sunburn and mast cell counts, and collagen degradation. Therefore, RvD1 inhibited UVB-induced skin oxidative stress and inflammation, rendering this resolving lipid mediator as a promising therapeutic agent.

Abstract
Zymography is a widely used technique for the study of proteolytic activities on the basis of protein substrate degradation. In this study, substrate immersing zymography was used in analyzing proteolysis of extracellular proteases. Instead of being added directly into a sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) gel, the substrates were added into the immersing solution after electrophoresis. Substrate immersing zymography could accurately determine the molecular weight of trypsin, and band intensities were linearly related to the amount of protease. The diversity of extracellular proteases produced by different marine bacteria was analyzed by substrate immersing zymography, and large variations of proteolysis were evidenced. The proteolytic activity of Pseudoalteromonas strains was more complicated than that of other strains. Five Pseudoalteromonas strains and five Vibrio strains were further analyzed by substrate immersing zymography with different substrates (casein and gelatin), and multiple caseinolytic and gelatinolytic profiles were detected. The extracellular proteolytic profiles of Pseudoalteromonas strains exhibited a large intraspecific variation. Molecular weight (Mw) of the main protease secreted by Vibrio was 35 kDa. Additionally, the time-related change trends of the activities of extracellular proteases produced by Pseudoalteromonas sp. SJN2 were analyzed by substrate immersing zymography. These results implied the potential application of substrate immersing zymography for the analysis of the diversity of bacterial extracellular proteases.

Efficacy of topical formulations containing Pimenta pseudocaryophyllus extract against UVB-induced oxidative stress and inflammation in hairless mice. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2013; 127:153-60. [PMID: 24041853 DOI: 10.1016/j.jphotobiol.2013.08.007] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2013] [Revised: 07/27/2013] [Accepted: 08/19/2013] [Indexed: 11/23/2022]
Abstract
Plants rich in antioxidant substances may be a promising strategy for preventing UV-induced oxidative and inflammatory damage of the skin. Pimenta pseudocaryophyllus is native to Brazil and presents flavonoids and other polyphenolic compounds in high concentration. Thus, the present study evaluated the possible effects of topical formulations containing P. pseudocaryophyllus ethanolic extract (PPE) at inhibiting UV-B irradiation-induced oxidative stress and inflammation. PPE was administered on the dorsal skin of hairless mice using two formulations: F1 (non-ionic emulsion with high lipid content) and F2 (anionic emulsion with low lipid content) before and after UV-B irradiation. The following parameters were evaluated in skin samples: edema, myeloperoxidase activity, cytokines levels, matrix metalloprotease-9 (MMP-9) secretion/activity, reduced glutathione (GSH), superoxide anion and lipid peroxidation levels, and mRNA expression for glutathione reductase and gp91phox. The UV-B irradiation increased all parameters, except for IL-10 levels and glutathione reductase mRNA expression, which were not altered, and GSH levels, which were reduced by exposure to UV-B light. Treatments with F1 and F2 containing PPE inhibited UV-B-induced edema formation (89% and 86%), myeloperoxidase activity (85% and 81%), IL-1β production (62% and 82%), MMP-9 activity (71% and 74%), GSH depletion (73% and 85%), superoxide anion (83% and 66%) and TBARS (100% and 100%) levels, increased glutathione reductase (2.54 and 2.55-fold) and reduced gp91phox (67% and 100%) mRNA expression, respectively. F2 containing PPE also increased IL-10 levels. Therefore, this study demonstrates the effectiveness of topical formulations containing PPE in inhibiting UV-B irradiation-induced inflammation and oxidative stress of the skin.

A large-scale epidemiological study to identify bacteria pathogenic to Pacific oyster Crassostrea gigas and correlation between virulence and metalloprotease-like activity. MICROBIAL ECOLOGY 2010; 59:787-798.

Abstract
A 4-year bacteriological survey (2003-2007) of four molluscs cultivated in France and faced with mortality episodes was performed by the French shellfish pathology network. The more abundant bacteria isolated during 92 mortality episodes, occurring mainly in Pacific oyster Crassostrea gigas, were identified by genotyping methods. It allowed us both to confirm the representativeness of Vibrio splendidus and Vibrio aestuarianus bacterial strains and to identify both a large number of Vibrio harveyi-related strains mainly detected during 2007 oyster mortality outbreaks and to a lesser extent bacterial strains identified as Shewanella colwelliana. Because metalloprotease has been reported to constitute a virulence factor in a few Vibrio strains pathogenic for C. gigas, several bacterial strains isolated in this study were screened to evaluate their pathogenicity in C. gigas spat by experimental infection and their ability to produce metalloprotease-like activity in the culture supernatant fluids. A high level (84%) of concordant results between azocaseinase activities and virulence of strains was obtained in this study. Because bacterial metalloprotease activities appeared as a common feature of pathogenic bacteria strains associated with mortality events of C. gigas reared in France, this phenotypic test could be useful for the evaluation of virulence in bacterial strains associated with such mortality episodes.

Abstract
Vibrio vulnificus has been known to secrete one form of metalloprotease VvpE (45 kDa) that is cleaved to 34 kDa-VvpE and 11 kDa-C-terminal propeptide via extracellular autoproteolysis. However, we found that extracellular secretion of both the 34 and 45 kDa forms of VvpE began in the early growth phase; moreover, 34 kDa-VvpE existed as the major form in V. vulnificus cell lysates and culture supernatants. In addition, extracellular secretion of both 34 and 45 kDa-VvpE was blocked by mutation of the pilD gene, which encodes for the type IV leader peptidase/N-methyltransferase of the type II general secretion system, and the blocked VvpE secretion was recovered by in trans-complementation of the wild-type pilD gene. These results indicate that 34 kDa-VvpE is the major form secreted along with 45 kDa-VvpE from the early growth phase via the PilD-mediated type II general secretion system.
