Gardenia jasminoides protects against cerulein-induced acute pancreatitis

AIM： To investigate the effect of Garden/a fasm/noides （GJ） on cerulein-induced acute pancreatitis （AP） in mice. METHODS： C57BL/6 mice weighing 18-20 g were divided into three groups. （1） Normal salinetreated group, （2） treatment with GJ at a dose of 0.1 g/kg, （3） treatment with GJ at a dose of 1 g/kg. GJ was administered orally （n = 6 per group） for 1 wk. Three hours later, the mice were given anintraperitoneal injection of cerulein （50 μg/kg）, a stable cholecystokinin （CCK） analogue, every hour for a total of 6h as described previously. The mice were sacrificed at 6 h after completion of cerulein injections. Blood samples were obtained to determine serum amylase, lipase and cytokine levels. The pancreas was rapidly removed for morphologic examination and scoring. A portion of pancreas was stored at -70℃ and prepared for the measurement of tissue myeloperoxidase （MPO） activity, an indicator of neutrophil sequestration, and for reverse-transcriptase PCR （RT-PCR） and real-time PCR measurements. RESULTS： Treatment with G.1 decreased significantly the severity of pancreatitis and pancreatitis-associated lung injury. Treatment with G.1 attenuated the severity of AP compared with saline-treated mice, as shown by reduction in pancreatic edema, neutrophil infiltration, serum amylase and lipase levels, serum cytokine levels, and mRNA expression of multiple inflammatory mediators. CONCLUSION： These results suggest that GJ attenuated the severity of AP as well as pancreatitisassociated lung injury.

Effects of Gardenia jasminoides extracts on cognition and innate immune response in an adult Drosophila model of Alzheimer's disease

Herbal extracts have been extensively used worldwide for their application on memory improvement, especially among aged and memory-deficit populations. In the present study, the memory loss induced by human Abeta protein over-expression in fruitfly Alzheimer's disease(AD) model was rescued by multiple extracts from Gardenia jasminoides. Three extracts that rich with gardenia yellow, geniposide, and gardenoside components showed distinct rescue effect on memory loss. Further investigation on adding gardenoside into a formula of Ganoderma lucidum, Panax notoginseng and Panax ginseng(GPP) also support its therapeutic effects on memory improvement. Interestingly, the application of GPP and gardenoside did not alter the accumulation of Abeta proteins but suppressed the expression of immune-related genes in the brain. These results revealed the importance and relevancy of anti-inflammation process and the underlying mechanisms on rescuing memory deficits, suggesting the potential therapeutic use of the improved GPP formulation in improving cognition in defined population in the future.

Verticase:a Fibrinolytic Enzyme Produced by Verticillium sp,Tj33,an Endophyte of Trachelospermum jasminoides

Plant endophytes are among the most important resources of biologically active metabolites. Twenty-three endophyte strains residing in Trachelospermum jasminoides were cultivated in vitro with the cultures assayed for the fibrinolytic substance production. As a result, the culture of VerticUlium sp. Tj33 was shown to be the most active. A fibrinolytic enzyme designated as verticase was subsequently purified from the supernatant of Verticillium sp. culture broth by a combination of DEAE-52, Sephadex G-75 and hydrophobic column chromatographies. Verticase, with its molecular mass of 31 kDa and pl of 8.5, was demonstrated to be homogeneous by sodium dodecyl suIfate-polyacrylamide gel electrophoresis and isoelectric focusing electrophoresis. Verticase is an enzyme that hydrolyzes fibrin directly without activation of plaminogen. It was stable in a broad pH range from 4 through to 11 with the optimal reaction pH value and temperature shown to be around 9-10 and 50-60℃, respectively. The fibrinolytic activity of verticase was severely inhibited by phenylmethylsulfony fluoride, indicating that verticase was a serine protease.

栀子(Gardenia jasminoides)GGPPS基因小亚基的克隆及表达分析

香叶基焦磷酸(geranyl pyrophosphate,GPP)是单萜的前体物质,而单萜是栀子内重要的活性成分。香叶基香叶基焦磷酸合酶(GGPPS)在萜类化合物、类胡萝卜素类化合物生物合成中处于关键位置,GGPPS主要分为香叶基香叶基焦磷酸合成酶大亚基(GGPPSlsu)和香叶基香叶基焦磷酸合成酶小亚基(GGPPSssu)。为了研究栀子GGPPS基因在栀子萜类生物合成中的作用,本研究成功从栀子品种‘林海一号’中提取RNA反转录合成cDNA,根据转录组测序拼接结果设计引物扩增得到栀子GGPPSssu的cDNA序列,分别命名为GjGGPPSssu1和GjGGPPSssu2,ORF区分别为1053 bp和915 bp。通过构建基因进化树,栀子GGPPSssu基因和其他植物的GGPPSssu基因聚为一类,属于香叶基香叶基焦磷酸合成酶小亚基基因。通过蛋白质序列比对表明GjGGPPSssu1有一个CxxxC(x为碱性氨基酸)的保守基元和一个FARM的保守基元,没有SARM保守基元,与SSUⅡ类基因相似;GjGGPPSssu2有两个CxxxC的保守基元,没有FARM保守基元和SARM保守基元,与SSUⅠ类基因相似。荧光定量PCR试验结果表明,GjGGPPSssu1在T4和T5时期有较高的表达水平,GjGGPPSssu2在栀子各生长时期的根部和果实中有较高水平的表达。推测GjGGPPSssu1基因与栀子黄色素合成相关,GjGGPPSssu2基因与单萜合成相关。本研究初步解析了栀子GGPPS基因的功能,为提高栀子药用品质提供了理论依据。

Potential mechanism of cholagogic effect about Gardenia Jasminoides Ellis(Zhizi)-mediated increase of bile acids urinary excretion in normal rats

Objectives： Gardenia Jasminoides Ellis（Zhizi）, belonging to Rubiaceae family, has been traditionally used for treatment cholestasis and jaundice for centuries in Asian countries. In the theory of Traditional Chinese Medicines, Zhizi could dispel dampness and heat via the urine to execute its choleretic effects. However, the potential molecular mechanism has been still poorly clarified. Here, we investigated the effect of different dose of Zhizi aqueous extract powder（0.3 g/kg/d and 0.9 g/kg/d） on urinary excretion of bile acids（BAs）, and defined the potential mechanism via renal BAs efflux transporters Mrp2 and Mrp4 in normal rats.Methods： Male Wistar rats were orally administrated with 0.3 or 0.9 g/kg/d dose of Zhizi aqueous extract powder for 2 weeks, then body weight, serum aminotransferase, total BAs concentrations in liver, bile,serum, kidney and urine, 1 h bile flow, 12-h urinary volume, biliary and urinary excretion amount of total BAs as well as protein expression of major renal BAs efflux transporter Mrp2 and Mrp4, were all evaluated.Results： Zhizi especially the high dose of Zhizi aqueous extract powder could reduce hepatic total BAs concentration. Additionally, bile flow and biliary excretion had no significant difference, but the remarkable increasing urinary excretion of BAs and 2 to 3 folds up-regulated renal Mrp2 expression were observed after administrated with Zhizi as compared with the control group.Conclusion： The findings indicate that Zhizi reduces hepatic total BAs level by increasing urinary excretion rather than the biliary excretion of BAs, which, in turn ascribed to elevated protein expression of Mrp2 at apical membrane of renal tubular epithelial cells.

Anti-TMV and Insecticidal Potential of Four Iridoid Glycosides from Gardenia Jasminoides Fruit

In agriculture, pests are largely controlled by agricultural chemicals. The vast majority of these pesticides are synthetic compounds, some of which are based on natural products, and a few of which are synthetic versions of natural products. Pests have evolved resistance to many of the current pesticides, often by alterations in the molecular target site. Thus, pesticides with new molecular target sites and modes of action are needed.
