1Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192
2Early Oligocene anatexis in the Yardoi gneiss dome,southern Tibet and geological implications显示文摘The Yardoi gneiss dome is located to the easternmost of the North Himalayan Gneiss Dome (NHGD),southern Tibet. It consists of metapelite,garnet amphibolite,granite and leucogranite,and is a key subject to constrain the formation and tectonic evolution of NHGD. SHRIMP zircon U/Pb data on the leucogranite yield an age of 35.3±1.1 Ma,which is substantially older than that of the similar leu-cogranites to the west. Sr and Nd isotope systematics indicate that this leucogranite was derived from partial melting of the mixed garnet amphibolite and metapelite. Our data suggest that (1) during the early stage of Himalayan magmatism,amphibolite dehydration melting overwhelmed that of the metapelite; and (2) such a melting at middle-lower crust might be a major factor that initiated the movement along the Southern Tibetan Detachment System (STDS).ZENG LingSen LIU Jing GAO LiE XIE KeJia WEN Li 2009Chinese Science Bulletin2009,54,1:61
3A meta-analysis of lamivudine for interruption of mother-to-child transmission of hepatitis B virus显示文摘AIM:To determine the therapeutic effect of lamivudine in late pregnancy for the interruption of motherto-child transmission(MTCT) of hepatitis B virus(HBV).METHODS:Studies were identified by searching available databases up to January 2011.Inclusive criteria were HBV-carrier mothers who had been involved in randomized controlled clinical trials(RCTs) with lamivudine treatment in late pregnancy,and newborns or infants whose serum hepatitis B surface antigen(HBsAg),hepatitis B e antigen(HBeAg) or HBV DNA had been documented.The relative risks(RRs) for interruption of MTCT as indicated by HBsAg,HBV DNA or HBeAg of newborns or infants were calculated with 95% confidence interval(CI) to estimate the efficacy of lamivudine treatment.RESULTS:Fifteen RCTs including 1693 HBV-carrier mothers were included in this meta-analysis.The overall RR was 0.43(95% CI,0.25-0.76;8 RCTs;Pheterogeneity = 0.04) and 0.33(95% CI,0.23-0.47;6 RCTs;Pheterogeneity = 0.93) indicated by newborn HBsAg or HBV DNA.The RR was 0.33(95% CI,0.21-0.50;6 RCTs;Pheterogeneity = 0.46) and 0.32(95% CI,0.20-0.50;4 RCTs;Pheterogeneity = 0.33) indicated by serum HBsAg or HBV DNA of infants 6-12 mo after birth.The RR(lamivudine vs hepatitis B immunoglobulin) was 0.27(95% CI,0.16-0.46;5 RCTs;Pheterogeneity = 0.94) and 0.24(95% CI,0.07-0.79;3 RCTs;P heterogeneity = 0.60) indicated by newborn HBsAg or HBV DNA,respectively.In the mothers with viral load < 106 copies/mL after lamivudine treatment,the efficacy(RR,95% CI) was 0.33,0.21-0.53(5 RCTs;Pheterogeneity = 0.82) for the interruption of MTCT,however,this value was not significant if maternal viral load was > 106 copies/mL after lamivudine treatment(P = 0.45,2 RCTs),as indicated by newborn serum HBsAg.The RR(lamivudine initiated from 28 wk of gestation vs control) was 0.34(95% CI,0.22-0.52;7 RCTs;Pheterogeneity = 0.92) and 0.33(95% CI,0.22-0.50;5 RCTs;Pheterogeneity = 0.86) indicated by newborn HBsAg or HBV DNA.The incidence of adverse effects of lamivudine was not higher in the mothers than in controls(P = 0.97).Only one study reported side effects of lamivudine in newborns.CONCLUSION:Lamivudine treatment in HBV carriermothers from 28 wk of gestation may interrupt MTCT of HBV efficiently.Lamivudine is safe and more efficient than hepatitis B immunoglobulin in interrupting MTCT.HBV MTCT might be interrupted efficiently if maternal viral load is reduced to < 106 copies/mL by lamivudine treatment.Lei Han Hong-Wei Zhang Jia-Xin Xie Qi Zhang Hong-Yang Wang Guang- Wen Cao 2011World Journal of Gastroenterology2011,17,38:61
4Immune mechanisms of Concanavalin A model of autoimmune hepatitis显示文摘As a chronic inflammatory disease of the liver,the pathogenic mechanisms of autoimmune hepatitis (AIH) have not yet been elucidated,with prognosis and diagnosis remaining unsatisfied.Currently the only viable treatments of AIH are immunosuppressant application and liver transplantation.It is considered that lack of good animal AIH models is the main reason for the shortage of a simple and efficient cure.The Concanavalin A (Con A) model is a typical and well established model for investigating T-cell and macrophage dependent liver injury in mice,which closely mimics the pathogenesis mechanisms and pathological changes of patients,and is regarded as the best experimental model for AIH research so far.In this paper we eluci-dated the pathogenic mechanisms of AIH and the evolution of relative animal models.We go on to further focus on Con A-induced liver injury from the point of immunological mechanisms and the change of cytokine levels.Finally,we manifested the clinical significance of the AIH animal models and the challenges they would meet during their future development.Hai-Xia Wang Man Liu Shun-Yan Weng Jing-Jing Li Chao Xie Hong-Lin He Wen Guan Yun-Sheng Yuan Jin Gao 2012World Journal of Gastroenterology2012,18,2:52
5A preliminary study of rare-metal mineralization in the Himalayan leucogranite belts, South Tibet显示文摘The Himalayan leucogranite occurs as two extensive(>1000 km) E-W trending belts on the Tibetan Plateau with the unique features. The leucogranite comprised biotite granite, two-mica/muscovite granite, tourmaline granite and garnet granite, which have been identified in previous studies, as well as albite granite and granitic pegmatite that were identified in this investigation. Fifteen leucogranite plutons were studied and 12 were found to contain rare-metal bearing minerals such as beryl(the representative of Be mineralization), columbite-group minerals, tapiolite, pyrochlore-microlite, fergusonite, Nb-Ta rutile(the representative of Nb-Ta mineralization), and cassiterite(the representative of Sn mineralization) mainly based on the field trip,microscope observation and microprobe analysis. The preliminary result shows that the Himalayan leucogranite is commonly related to the rare-metal mineralization and warrants future investigation. Further exploration and intensive research work is important in determining the rare-metal resource potential of this area.WANG RuCheng WU FuYuan XIE Lei LIU XiaoChi WANG JiaMin YANG Lei LAI Wen LIU Chen 2017Science China Earth Sciences2017,60,9:45

8MicroRNA-125b Induces Cancer Cell Apoptosis Through Suppression of Bcl-2 Expression显示文摘MicroRNAs(miRNAs) are small,noncoding RNAs which can often act as an oncogene or a tumor suppressor.Several miRNAs are associated with the development of hepatocellular carcinoma(HCC).We demonstrated that miR-125b significantly suppresses HCC cell proliferation and promotes apoptosis by inhibiting the gene expression of the anti-apoptotic protein,Bcl-2.Bioinformatic analysis indicated that the 3'UTR of Bcl-2 has binding sites for miR-125b.Luciferase reporter assay confirmed the ability of miR-125b to dramatically suppress Bcl-2 transcription,suggesting that Bcl-2 is a target gene for miR-125b.We concluded that miR-125b acts as a tumor suppressor in hepatic tumor development by targeting Bcl-2 and inducing cancer cell apoptosis.Aihua Zhao Quan Zeng Xiaoyan Xie Junnian Zhou Wen Yue Yali Li Xuetao Pei 2012Journal of Genetics and Genomics2012,39,1:30

10Development of Intensified Technologies of Vanadium-Bearing Titanomagnetite Smelting显示文摘It was very difficult for the smelting of vanadium-bearing titanomagnetite by blast furnace because the content of TiO2 of blast furnace slag could amount to 20%-25%.After long term development and continuous improvement,special intensified smelting technologies for vanadium-bearing titanomagnetite by blast furnace were obtained and improved gradually.With the improvement of beneficiated material level and equipment level,smelting intensity has been increased gradually and the highest comprehensive smelting intensity reached 1.45 t/(m3·d).Technical-economic indexes of blast furnace have also been increased remarkably.The highest utilization coefficient exceeded 2.7 t/(m3·d)on the condition that the burden grade was only about 50%.FU Wei-guo WEN Yong-cai XIE Hong-en 2011Journal of Iron and Steel Research(International)2011,18,4:26
11Average slip-rate and recent large earthquake ruptures along the Garzê-Yushu fault显示文摘Our field investigation obtains new evidence of the later Quaternary activity and recent large earthquake ruptures of the Garzê-Yushu fault. The average left-lateral slip-rate along the fault is determined to be (12 ± 2) mm/a for the last 50000 years from both offset landforms and ages of the correlative sediments. This result is very close to the estimated average left-lateral slip-rate for the Xianshuihe fault, suggesting that the horizontal movement along the northern boundary of the Sichuan-Yunnan active tectonic block and the northeastern boundary of the Qiangtang active tectonic block has been basically harmonious during the later Quaternary period. Remains of ground ruptures of recent large earthquakes have been discovered along all 3 segments of the fault, of which, the 1896 rupture on the northwestern segment is at least 70 km long, and its corresponding earthquake could be of moment magnitude 7.3. The latest rupture on the middle segment of the fault has a length of about 180 km, and was produced by an unknown-age large earthquake that could have a moment magnitude of about 7.7. Along the southeastern segment of the fault, the latest unknown-age rupture is about 65 km long and has a maximum left-lateral coseismic displacement of 5.3 m, and its corresponding earthquake is estimated to be as large as about 7.3 of moment magnitude. Based on relevant investigation, an inference has been drawn that the later two large earthquakes probably occurred in 1854 and 1866, respectively. These demonstrate that the individual segments of the studied Garzê-Yushu fault are all able to produce large earthquakes.WEN Xueze (闻学泽) XU Xiwei (徐锡伟) ZHENG Rongzhang (郑荣章) XIE Yingqing (谢英情) WAN Chuang (万 创) 2003Science China Earth Sciences2003,46,z2:24
12Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15(8.3%), 16(8.9%), 15(8.3%) and 17(9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise. The symptoms were relieved without special treatment in all of the patients.CONCLUSION: Both 7- and 10-d quadruple furazolidone-based therapies achieve satisfactory H. pylori eradication rates.Yong Xie Yin Zhu Hong Zhou Zhi-Fa Lu Zhen Yang Xu Shu Xiao-Bai Guo Hui-Zhen Fan Jian-Hua Tang Xue-Ping Zeng Jian-Bo Wen Xiao-Qing Li Xing-Xing He Jiu-Hong Ma Dong-Sheng Liu Cai-Bin Huang Ning-Jian Xu Nong-Rong Wang Nong-Hua Lu 2014World Journal of Gastroenterology2014,20,32:24

14Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment.Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao 2021Acta Pharmaceutica Sinica B2021,11,12:23
15Daclatasvir plus asunaprevir in treatment-na?ve patients with hepatitis C virus genotype 1b infection显示文摘AIM To assess daclatasvir plus asunaprevir(d UAL) in treatment-na?ve patients from China's Mainland, Russia and South Korea with hepatitis C virus(HCV) genotype 1 b infection. METHODS Patients were randomly assigned(3:1) to receive 24 wk of treatment with d UAL(daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period(immediate treatment arm) or following 12 wk of matching placebo(placebodeferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12(SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin(70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in d UAL-treated patients compared with placebo patients during the first 12 wk(doubleblind phase), and during 24 wk of d UAL in both arms combined.RESULTS In total, 207 patients were randomly assigned to immediate(n = 155) or placebo-deferred(n = 52) treatment. Most patients were Asian(86%), female(59%) and aged < 65 years(90%). Among them, 13% had cirrhosis, 32% had IL28 B non-CC genotypes and 53% had baseline HCV RNA levels of ≥ 6 million IU/m L. Among patients in the immediate treatment arm, SVR12 was achieved by 92%(95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate(70%). SVR12 was largely unaffected by cirrhosis(89%), age ≥ 65 years(92%), male sex(90%), baseline HCV RNA ≥ 6 million(89%) or IL28 B non-CC genotypes(96%), although SVR12 was higher among patients without(96%) than among those with(53%) baseline NS5 A resistanceassociated polymorphisms(at L31 or Y93 H). during the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving d UAL. during 24 wk of d UAL therapy(combined arms), the most common adverse events(≥ 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities(alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued d UAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths.CONCLUSION d UAL was well-tolerated during this phase 3 study, and SVR12 with d UAL treatment(92%) exceeded thehistorical SVR rate for peg-interferon plus ribavirin of 70%.Lai Wei Fu-Sheng Wang Ming-Xiang Zhang Ji-Dong Jia Alexey A Yakovlev Wen Xie Eduard Burnevich Jun-Qi Niu Yong Jin Jung Xiang-Jun Jiang Min Xu Xin-Yue Chen Qing Xie Jun Li Jin-Lin Hou Hong Tang Xiao-guang Dou Yash Gandhi Wen-Hua Hu Fiona McPhee Stephanie Noviello Michelle Treitel Ling Mo Jun Deng 2018World Journal of Gastroenterology2018,24,12:17
16H_2S Protecting against Lung Injury following Limb Ischemia-reperfusion by Alleviating Inflammation and Water Transport Abnormality in Rats显示文摘Objective To investigate the effect of H2 S on lower limb ischemia-reperfusion(LIR) induced lung injury and explore the underlying mechanism. Methods Wistar rats were randomly divided into control group, IR group, IR+ Sodium Hydrosulphide(NaHS) group and IR+ DL-propargylglycine(PPG) group. IR group as lung injury model induced by LIR were given 4 h reperfusion following 4 h ischemia of bilateral hindlimbs with rubber bands. NaHS(0.78 mg/kg) as exogenous H2 S donor and PPG(60 mg/kg) which can suppress endogenous H2 S production were administrated before LIR, respectively. The lungs were removed for histologic analysis, the determination of wet-to-dry weight ratios and the measurement of mRNA and protein levels of aquaporin-1(AQP1), aquaporin-5(AQP5) as indexes of water transport abnormality, and mRNA and protein levels of Toll-like receptor 4(TLR4), myeloid differentiation primary-response gene 88(MyD88) and p-NF-κB as indexes of inflammation. Results LIR induced lung injury was accompanied with upregulation of TLR4-Myd88-NF-κB pathway and downregulation of AQP1/AQP5. NaHS pre-treatment reduced lung injury with increasing AQP1/AQP5 expression and inhibition of TLR4-Myd88-NF-κB pathway, but PPG adjusted AQP1/AQP5 and TLR4 pathway to the opposite side and exacerbated lung injury. Conclusion Endogenous H2 S, TLR4-Myd88-NF-κB pathway and AQP1/AQP5 were involved in LIR induced lung injury. Increased H2 S would alleviate lung injury and the effect is at least partially depend on the adjustment of TLR4-Myd88-NF-κB pathway and AQP1/AQP5 expression to reduce inflammatory reaction and lessen pulmonary edema.QI Ying Chun CHEN Wen LI Xiao Ling WANG Yu Wei XIE Xiao Hua 2014Biomedical and Environmental Sciences2014,27,6:17
17Minimally invasive surgery alone compared with intensity-modulated radiotherapy for primary stage I nasopharyngeal carcinoma显示文摘Background:The National Comprehensive Cancer Network guidelines recommend intensity-modulated radiotherapy(IMRT)as the primary curative treatment for newly diagnosed nasopharyngeal carcinoma(NPC),but the radiation-related complications and relatively high medical costs remain a consequential burden for the patients.Endoscopic nasopharyngectomy(ENPG)was successfully applied in recurrent NPC with radiation free and relatively low medical costs.In this study,we examined whether ENPG could be an effective treatment for localized stage I NPC.Methods:Ten newly diagnosed localized stage I NPC patients voluntarily received ENPG alone from June 2007 to September 2017 in Sun Yat-sen University Cancer Center.Simultaneously,the data of 329 stage I NPC patients treated with IMRT were collected and used as a reference cohort.The survival outcomes,quality of life(QOL),and medical costs between two groups were compared.Results:After a median follow-up of 59.0 months(95%CI 53.4-64.6),no death,locoregional recurrence,or distant metastasis was observed in the 10 patients treated with ENPG.The 5-year overall survival,local relapse-free survival,regional relapse-free survival,and distant metastasis-free survival among the ENPG-treated patients was similar to that among the IMRT-treated patients(100%vs.99.1%,100%vs.97.7%,100%vs.99.0%,100%vs.97.4%,respectively,P>0.05).In addition,compared with IMRT,ENPG was associated with decreased total medical costs($4090.42±1502.65 vs.$12620.88±4242.65,P<0.001)and improved QOL scores including dry mouth(3.3±10.5 vs.34.4±25.8,P<0.001)and sticky saliva(3.3±10.5 vs.32.6±23.3,P<0.001).Conclusions:ENPG alone was associated with promising long-term survival outcomes,low medical costs,and satisfactory QOL and might therefore be an alternative strategy for treating newly diagnosed localized stage I NPC patients who refused radiotherapy.However,the application of ENPG should be prudent,and prospective clinical tri-als were needed to further verify the results.You-Ping Liu Xing Lv Xiong Zou Yi-Jun Hua Rui You Qi Yang Le Xia Shao-Yan Guo Wen Hu Meng-Xia Zhang Si-Yuan Chen Mei Lin Yu-Long Xie Li-Zhi Liu Rui Sun Pei-Yu Huang Wei Fan Xiang Guo Ming-Huang Hong Ming-Yuan Chen 2019Cancer Communications2019,39,1:17

19Transcription Factor WRKY70 Displays Important but No Indispensable Roles in Jasmonate and Salicylic Acid Signaling显示文摘The transcription factor WRKY70 was previously reported to be a common component in salicylic acid(SA) and jasmonate(JA) mediated signal pathways in Arabidopsis.Here,we present that the inactivation of the WRKY70 gene in wrky70-1 mutant does not alter the responses of both JA and SA,and that wrky70 mutation is unable to restore the coi1 mutant in JA responses.However,overexpression of WRKY70 reduces JA responses such as expression of JA-induced genes and JA-inhibitory root growth,and activates expression of SA-inducible PR1.These data indicate that the WRKY70 is important but not indispensable for JA and SA signaling,and that other regulators may display the redundant role with WRKY70 in modulation of JA and SA responses in Arabidopsis.Furthermore,we showed that JA inhibits expression of WRKY70 and PR1 by both COI1-dependent and COI1-independent pathways.Chun-Mei Ren Qi Zhu Bi-Da Gao Shao-Ying Ke Wan-Cong Yu Dao-Xin Xie Wen Peng 2008Journal of Integrative Plant Biology2008,50,5:15
