| 1 | Hydrogen Sulfide Promotes Root Organogenesis in Ipomoea batatas, Salix matsudana and Glycine max显示文摘In this report, we demonstrate that sodium hydrosulfide (NaHS), a hydrogen sulfide (H2S) donor, promoted adventitious root formation mediated by auxin and nitric oxide (NO). Application of the H2S donor to seedling cuttings of sweet potato (Ipomoea batatas L.) promoted the number and length of adventitious roots in a dose-dependent manner. It was also verified that H2S or HS- rather than other sulfur-containing components derived from NaHS could be attributed to the stimulation of adventitious root formation. A rapid increase in endogenous H2S, indole acetic acid (IAA) and NO were sequentially observed in shoot tips of sweet potato seedlings treated with HaHS. Further investigation showed that H2S-mediated root formation was alleviated by N-1-naphthylphthalamic acid (NPA), an IAA transport inhibitor, and 2-(4-carboxyphenyl)- 4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), an NO scavenger. Similar phenomena in H2S donor-dependent root organogenesis were observed in both excised willow (Salix matsudana var. tortuosa Vilm) shoots and soybean (Glycine max L.) seedlings. These results indicated that the process of H2S-induced adventitious root formation was likely mediated by IAA and NO, and that H2S acts upstream of IAA and NO signal transduction pathways. | Hua Zhang Jun Tang Xiao-Ping Liu Yun Wang Wei Yu Wei-Yan Peng Fang Fang Dai-Fu Ma Zhao-Jun Wei Lan-Ying Hu | 2009 | Journal of Integrative Plant Biology2009,51,12: | 58 |

| 4 | RLINl,encoding a putative coproporphyrinogen Ⅲ oxidase,is involved in lesion initiation in rice显示文摘Lesion mimic is necrotic lesions on plant leaf or stem in the absence of pathogenic infection,and its exact biological mechanism is varied.By a large-scale screening of our T-DNA mutant population,we identified a mutant rice lesion initiation 1(rlin1),which was controlled by a single nuclear recessive gene.Map-based cloning revealed that RLIN1 encoded a putative coproporphyrinogen Ⅲ oxidase in tetrapyrrole biosynthesis pathway.Sequencing results showed that a G to T substitution occurred in the second exon of RLIN1 and led to a missense mutation from Asp to Tyr.Ectopic expression of RLIN1 could rescue rlin1 lesion mimic phenotype.Histochemical analysis demonstrated that lesion formation in rlin1 was light-dependent accompanied by reactive oxygen species accumulated.These results suggest that tetrapyrrole participates in lesion formation in rice. | Changhui Sun Linchuan Liu Jiuyou Tang Aihong Lin Fantao Zhang Jun Fang Genfa Zhang Chengcai Chu | 2011 | Journal of Genetics and Genomics2011,38,1: | 31 |

| 6 | Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment. | Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu | 2020 | Acta Pharmacologica Sinica2020,41,9: | 32 |
| 7 | Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios. | Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang | 2022 | Science China(Life Sciences)2022,65,5: | 32 |

| 12 | Global leaf nitrogen and phosphorus stoichiometry and their scaling exponent显示文摘Leaf nitrogen(N) and phosphorus(P) concentrations constrain photosynthetic and metabolic processes,growth and the productivity of plants. Their stoichiometry and scaling relationships regulate the allocation of N and P from subcellular to organism, and even ecosystem levels, and are crucial to the modelling of plant growth and nutrient cycles in terrestrial ecosystems. Prior work has revealed a general biogeographic pattern of leaf N and P stoichiometric relationships and shown that leaf N scales roughly as two-thirds the power of P. However, determining whether and how leaf N and P stoichiometries, especially their scaling exponents, change with functional groups and environmental conditions requires further verification. In this study, we compiled a global data set and documented the global leaf N and P concentrations and the N:P ratios by functional group, climate zone and continent. The global overall mean leaf N and P concentrations were 18.9 mg g^(-1) and 1.2 mg g^(-1), respectively, with significantly higher concentrations in herbaceous than woody plants(21.72 mg g^(-1) vs. 18.22 mg g^(-1) for N; and 1.64 mg g^(-1) vs. 1.10 mg g^(-1) for P). Both leaf N and P showed higher concentrations at high latitudes than low latitudes. Among six continents, Europe had the highest N and P concentrations(20.79 and 1.54 mg g^(-1)) and Oceania had the smallest values(10.01 and 0.46 mg g^(-1)). These numerical values may be used as a basis for the comparison of other individual studies. Further, we found that the scaling exponent varied significantly across different functional groups,latitudinal zones, ecoregions and sites. The exponents of herbaceous and woody plants were 0.659 and0.705, respectively, with significant latitudinal patterns decreasing from tropical to temperate to boreal zones. At sites with a sample size ≥10, the values fluctuated from 0.366 to 1.928, with an average of 0.841.Several factors including the intrinsic attributes of different life forms, P-related growth rates and relative nutrient availability of soils likely account for the inconstant exponents of leaf N vs. P scaling relationships. | Di Tian Zhengbing Yan Karl J.Niklas Wenxuan Han Jens Kattge Peter B.Reich Yongkai Luo Yahan Chen Zhiyao Tang Huifeng Hu Ian J.Wright Bernhard Schmid Jingyun Fang | 2018 | National Science Review2018,5,5: | 24 |

| 14 | Left posterior fascicular block: a new endpoint of ablation for verapamil-sensitive idiopathic ventricular tachycardia显示文摘Background Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is known to be due to re-entry mechanism but the exact nature of reentrant circuit in ILVT is not fully elucidated. Radiofrequency (RF) ablation was applied during ventricular tachycardia (VT) and termination of the VT or abolishing the inducibility of the tachycardia was used as an endpoint for successful RF. In this study, the left posterior fascicular block in surface electrocardiogram (ECG) was used as a new endpoint of ablation to cure ILVT. Methods Electrophysiological studies and radiofrequency ablation were performed in 39 consecutive patients [30 men, 9 women; age ranging from 10 to 64 years, mean (29±16) years] with verapamil-sensitive ILVT and structurally normal hearts. VT could be terminated by the intravenous administration of verapamil in all patients. The target site was the midseptum of LV where the earliest Purkinje potentials were recorded during VT. RF current was applied to the target site with or without late diastolic potential (LDP) during sinus rhythm in 37 patients and during VT in 2 patients to meet the ablation endpoint: the left posterior fascicular block in the surface ECG. Results Thirty-seven patients with ILVT had been treated by RF ablation during sinus rhythm and two had been treated during VT. All of them met the endpoint of the left posterior fascicular block. Thirty-eight cases were symptom-free without medications during the follow-up period (range from 3 to 95 months, median 17 months). One patient developed a clinical recurrence and the left posterior fascicular block in surface ECG disappeared. The patient received another treatment. The endpoint was met and the procedure was successful. Conclusions The left posterior fascicular block in surface ECG used as an endpoint of RF ablation to treat ILVT is effective. It is important especially in those patients whose VT can not be induced or the inducible condition is unstable. The effective endpoint implied that the left posterior fascicle might be a critical part of the re-entrant circuit. | MA Fu-sheng MA Jian TANG Kai HAN Hao JIAYu-he FANG Pi-hua CHU Jian-min PU Jie-lin ZHANG Shu | 2006 | Chinese Medical Journal2006,,5: | 21 |
| 15 | Microbubble-enhanced ultrasound exposure improves gene transfer in vascular endothelial cells显示文摘AIM: To explore the effects of ultrasound exposure combined with microbubble contrast agent (SonoVue) on the permeability of the cellular membrane and on the expression of plasmid DNA encoding enhanced green fluorescent protein (pEGFP) transfer into human umbilical vein endothelial cells (HUVECs). METHODS: HUVECs with fluorescein isothiocyanate- dextran (FD500) and HUVECs with pEGFP were exposed to continuous wave (1.9 MHz, 80.0 mW/cm2) for 5 min, with or without a SonoVue. The percentage of FD500 taken by the HUVECs and the transient expression rate of pEGFP in the HUVECs were examined by fluorescence microscopy and flow cytometry, respectively. RESULTS: The percentage of FD500-positive HUVECs in the group of ultrasound exposure combined with SonoVue was significantly higher than that of the group of ultrasound exposure alone (24.0% ± 5.5% vs 66.6% ± 4.1%, P < 0.001). Compared with the group of ultrasound exposure alone, the transfection expression rate of pEGFP in HUVECs was markedly increased with the addition of SonoVue (16.1% ± 1.9% vs 1.5% ± 0.2%, P < 0.001). No statistical significant difference was observed in the HUVECs survival rates between the ultrasound group with and without the addition of SonoVue (94.1% ± 2.3% vs 91.1% ± 4.1%).CONCLUSION: The cell membrane permeability of HUVECs and the transfection efficiency of pEGFP into HUVECs exposed to ultrasound are significantly increased after addition of an ultrasound contrast agent withoutobvious damage to the survival of HUVECs. This non- invasive gene transfer method may be a useful tool for clinical gene therapy of hepatic tumors. | Fang Nie Hui-Xiong Xu Qing Tang Ming-De Lu | 2006 | World Journal of Gastroenterology2006,12,46: | 21 |
| 16 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019,6,4: | 21 |
| 17 | BMAL1 knockout macaque monkeys display reduced sleep and psychiatric disorders显示文摘Circadian disruption is a risk factor for metabolic, psychiatric and age-related disorders, and non-human primate models could help to develop therapeutic treatments. Here, we report the generation of BMAL1 knockout cynomolgus monkeys for circadian-related disorders by CRISPR/Cas9 editing of monkey embryos. These monkeys showed higher nocturnal locomotion and reduced sleep, which was further exacerbated by a constant light regimen. Physiological circadian disruption was reflected by the markedly dampened and arrhythmic blood hormonal levels. Furthermore, BMAL1-deficient monkeys exhibited anxiety and depression, consistent with their stably elevated blood cortisol, and defective sensory processing in auditory oddball tests found in schizophrenia patients. Ablation of BMAL1 up-regulated transcriptional programs toward inflammatory and stress responses, with transcription networks associated with human sleep deprivation, major depressive disorders, and aging. Thus, BMAL1 knockout monkeys are potentially useful for studying the physiological consequences of circadian disturbance, and for developing therapies for circadian and psychiatric disorders. | Peiyuan Qiu Jian Jiang Zhen Liu Yijun Cai Tao Huang Yan Wang Qiming Liu Yanhong Nie Fang Liu Jiumu Cheng Qing Li Yun-Chi Tang Mu-ming Poo Qiang Sun Hung-Chun Chang | 2019 | National Science Review2019,6,1: | 21 |
| 18 | Changed clinical aspects of primary liver cancer in China during the past 30 years显示文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis. | Bing-Hui Yang, Jing-Lin Xia, Li-Wen Huang, Zhao-You Tang, Ming-Shan Chen, Jin-Qing Li, An-Min Liang, Qin-Guo Mo, Hui-Shan Lu, Chao-Liu Dai, Lu-Nan Yan, Zhi-Jian Yu, Rong-Sheng Rao, Le-Qun Li, Zhi-Xiong Su, Zhuang-Wei Fang Shanghai, China Liver Cancer Institute & Zhongshan Hospital, Fudan University, Shanghai 200032, China Tumor Hospital, Zhongshan University, Guangzhou 510000, China Tumor Hospital, Guangxi Medical Universi- ty, Nanning 530000, China Xiehe Hospital, Fujian Medical University, Fuzhou 350000, China Second Hos- pital, Chinese Medical University, Shenyang 110000, China Huaxi Hospital, Sichuan University, Chengdu 610041, China Hospital Affiliated to Nantong Medical University, Nantong 226000 , China Second Hospital, Jiangxi Medical University, Nanchang 330000 , China First Hospital Affiliated to Guangxi Medical University, Nanning 530000 , China People’s Hospital of Hainan Province, Haikou 570000, China | 2004 | Hepatobiliary & Pancreatic Diseases International2004,3,2: | 20 |
| 19 | Remimazolam benzenesulfonate anesthesia effectiveness in cardiac surgery patients under general anesthesia显示文摘BACKGROUND Sedation with propofol injections is associated with a risk of addiction,but remimazolam benzenesulfonate is a comparable anesthetic with a short elimination half-life and independence from cell P450 enzyme metabolism.Compared to remimazolam,remimazolam benzenesulfonate has a faster effect,is more quickly metabolized,produces inactive metabolites and has weak drug interactions.Thus,remimazolam benzenesulfonate has good effectiveness and safety for diagnostic and operational sedation.AIM To investigate the clinical value of remimazolam benzenesulfonate in cardiac surgery patients under general anesthesia.METHODS A total of 80 patients who underwent surgery in the Department of Cardiothoracic Surgery from August 2020 to April 2021 were included in the study.Using a random number table,patients were divided into two anesthesia induction groups of 40 patients each:remimazolam(0.3 mg/kg remimazolam benzenesulfonate)and propofol(1.5 mg/kg propofol).Hemodynamic parameters,inflammatory stress response indices,respiratory function indices,perioperative indices and adverse reactions in the two groups were monitored over time for comparison.RESULTS At pre-anesthesia induction,the remimazolam and propofol groups did not differ regarding heart rate,mean arterial pressure,cardiac index or volume per wave index.After endotracheal intubation and when the sternum was cut off,mean arterial pressure and volume per wave index were significantly higher in the remimazolam group than in the propofol group(P<0.05).After endotracheal intubation,the oxygenation index and the respiratory index did not differ between the groups.After endotracheal intubation and when the sternum was cut off,the oxygenation index values were significantly higher in the remimazolam group than in the propofol group(P<0.05).Serum interleukin-6 and tumor necrosis factor-αlevels 12 h after surgery were significantly higher than before surgery in both groups(P<0.05).The observation indices were re-examined 2 h after surgery,and the epinephrine,cortisol and blood glucose levels were significantly higher in the remimazolam group than in the propofol group(P<0.05).The recovery and extubation times were significantly lower in the remimazolam group than in the propofol group(P<0.05);there were significantly fewer adverse reactions in the remimazolam group(10.00%)than in the propofol group(30.00%;P<0.05).CONCLUSION Compared with propofol,remimazolam benzenesulfonate benefited cardiac surgery patients under general anesthesia by reducing hemodynamic fluctuations.Remimazolam benzenesulfonate influenced the surgical stress response and respiratory function,thereby reducing anesthesia-related adverse reactions. | Fang Tang Jian-Min Yi Hong-Yan Gong Zi-Yun Lu Jie Chen Bei Fang Chen Chen Zhi-Yi Liu | 2021 | World Journal of Clinical Cases2021,9,34: | 19 |
| 20 | Effects of ginsenoside Rh2 on growth and migration of pancreatic cancer cells显示文摘AIM:To investigate the effects of ginsenoside Rh2 on the human pancreatic cancer cell line Bxpc-3.METHODS:The human pancreatic cancer cell line Bxpc-3 was cultured in vitro and treated with or without ginsenoside Rh2.Growth rates for Bxpc-3 cells were assessed by methyl thiazolyl tetrazolium(MTT) and colony formation assays.Cell cycle changes were analyzed by flow cytometry.Apoptosis was measured by flow cytometry and Hoechst 33258 fluorescence staining.A scratch assay and a Matrigel invasion assay were used to detect cell migration and invasion.Expression of Bax,Bcl-2,survivin,cyclin D1,matrix metalloproteinase(MMP)-2,MMP-9,cleaved caspase-3,caspase-8,and caspase-9 mRNA were determined by reverse transcriptase-polymerase chain reaction(RT-PCR).Bax,Bcl-2,survivin,cyclin D1,cleaved caspase-3,caspase-8 and caspase-9 protein levels were examined by western blotting.Expression of MMP-2 and MMP-9 proteins in culture supernatants were determined by enzymelinked immunosorbent assay(ELISA).RESULTS:Rh2 significantly inhibited Bxpc-3 cell proliferation in a dose-and time-dependent manner,as evaluated by the MTT(P < 0.05) and colony formation assays(P < 0.05).Compared to the control group,Rh2 significantly increased the percentage of Bxpc-3 cells in the G 0 /G 1 phase from 43.32% ± 2.17% to 71.32% ± 1.16%,which was accompanied by a decrease in S phase(from 50.86% ± 1.29% to 28.48% ± 1.18%) and G 2 /M phase(from 5.81% ± 1.19% to 0.20% ± 0.05%) in a dose-dependent manner(P < 0.05),suggesting that Rh2 arrested cell cycle progression at the G 0 /G 1 phase,as measured by flow cytometry.Compared to the control group,cells treated with Rh2 showed significantly higher apoptosis ratios in a dosedependent manner(percentage of early apoptotic cells:from 5.29% ± 2.28% to 38.90% ± 3.42%(F = 56.20,P < 0.05);percentage of late apoptotic cells:from 4.58% ± 1.42% to 36.32% ± 2.73%(F = 86.70,P < 0.05).Rh2 inhibited Bxpc-3 cell migration and invasion,as detected by scratch wound healing assay and Matrigel invasion assay [percentages of scratch wound healing for 12 h,24 h and 48 h(control vs experimental group):37.3% ± 4.8%vs 18.30% ± 1.65%,58.7% ± 3.5% vs 38.00% ± 4.09% and 93.83% ± 4.65% vs 65.50% ± 4.09%,respectively;t = 6.489,t = 6.656 and t = 7.926,respectively,P < 0.05;the number of cells invading at various concentrations(0 μmol/L,35 μmol/L,45 μmol/L and 55 μmol/L):81.10 ± 9.55,46.40 ± 6.95,24.70 ± 6.88 and 8.70 ± 3.34,respectively(F = 502.713,P < 0.05)].RT-PCR,western blotting or ELISA showed that mRNA and protein expression of Bax,cleaved caspase-3 and caspase-9 were upregulated(P < 0.05),while mRNA and protein expression of Bcl-2,survivin,cyclin D1,MMP-2 and MMP-9 were downregulated(P < 0.05).CONCLUSION:Ginsenoside Rh2 inhibits proliferation,migration and invasion and induces apoptosis of the human pancreatic cancer cell line Bxpc-3. | Xi-Ping Tang Guo-Du Tang Chun-Yun Fang Zhi-Hai Liang Lu-Yi Zhang | 2013 | World Journal of Gastroenterology2013,19,10: | 19 |
