2Effects of large dose of dexamethasone on inflammatory mediators and pancreatic cell apoptosis of rats with severe acute pancreatitis显示文摘AIM: To investigate the influence of high dose of dexamethasone on inflammatory mediators and apoptosis of rats with severe acute pancreatitis (SAP). METHODS: SAP rats were randomly assigned to the model group and treatment group while the normal rats were assigned to the sham operation group. The mortality,ascite volumes,ascites/body weight ratio and pancreas pathological changes of all rats were observed at 3,6 and 12 h after operation. Their contents of amylase and endotoxin in plasma and contents of tumor necrosis factor (TNF-α),phospholipase A2 (PLA2) and IL-6 in serum were also determined. The microarray sections of their pancreatic tissues were prepared,terminal transferase dUTP nick end labeling (TUNEL) staining was performed and apoptotic indexes were calculated. RESULTS: There was no marked difference between treatment group and model group in survival. The contents of amylase and endotoxin in plasma and contents of TNF-α,PLA2 and IL-6 in serum,ascite volumes,ascites/body weight ratio and pancreas pathological scores were all lower in treatment group than in model group to different extents at different time points P < 0.05,58.3 (26.4) ng/L vs 77.535 (42.157) ng/L in TNF-α content,8.00 (2.00) points vs 9.00 (2.00) points in pathological score of pancreas respectively; P < 0.01,0.042 (0.018) EU/mL vs 0.056 (0.0195) EU/mL in endotoxin content,7791 (1863) U/L vs 9195 (1298) U/L in plasma amylase content,1.53 (0.79) vs 2.38 (1.10) in ascites/body weight ratio,8.00 (1.00) points vs 11.00 (1.50) points in pathological score of pancreas; P < 0.001,3.36 (1.56) ng/L vs 5.65 (1.08) ng/L in IL-6 content,4.50 (2.00) vs 7.20 (2.00),4.20 (1.60) vs 6.40 (2.30),3.40 (2.70) vs 7.90 (1.70) in ascite volumes,respectively. The apoptotic indexes of pancreas head and pancreas tail were all higher in treatment group than in model group at 6 h P < 0.01,0.00 (2.00)% vs 0.00 (0.00)%,0.20 (1.80) vs 0.00 (0.00) in apoptosis indexes,respectively. CONCLUSION: The mechanism of dexamethasone treatment in acute pancreatitis is related to its inhibition of inflammatory mediator generation and induction of pancreatic acinar cell apoptosis.Xi-Ping Zhang Li Chen Qi-Fang Hu Hua Tian Ru-Jun Xu Zhi-Wei Wang Ke-Yi Wang Qi-Hui Cheng Wei Yan Yun Li Qing-Yu Li Qing He Fei Wang 2007World Journal of Gastroenterology2007,13,41:29
3Effect of clinician-patient communication on compliance with flupentixol-melitracen in functional dyspepsia patients显示文摘AIM: To explore whether clinician-patient communication affects adherence to psychoactive drugs in functional dyspepsia(FD) patients with psychological symptoms. METHODS: A total of 262 FD patients with psychological symptoms were randomly assigned to four groups. The patients in Groups 1-3 were given flupentixol-melitracen(FM) plus omeprazole treatment. Those in Group 1 received explanations of both the psychological and gastrointestinal(GI) mechanisms of the generation of FD symptoms and the effects of FM. In Group 2, only the psychological mechanisms were emphasized. The patients in Group 3 were not given an explanation for the prescription of FM. Those in Group 4 were given omeprazole alone. The primary endpoints of this study were compliance rate and compliance index to FM in Groups 1-3. Survival analyses were also conducted. The secondary end points were dyspepsia and psychological symptom improvement in Groups 1-4. The correlations between the compliance indices and the reductions in dyspepsia and psychological symptom scores were also evaluated in Groups 1-3.RESULTS: After 8 wk of treatment, the compliance rates were 67.7% in Group 1, 42.4% in Group 2 and 47.7% in Group 3(Group 1 vs Group 2, P = 0.006; Group 1 vs Group 3, P = 0.033). The compliance index(Group 1 vs Group 2, P = 0.002; Group 1 vs Group 3, P = 0.024) with the FM regimen was significantly higher in Group 1 than in Groups 2 and 3. The survival analysis revealed that the patients in Group 1 exhibited a significantlyhigher compliance rate than Groups 2 and 3(Group 1 vs Group 2, P = 0.002; Group 1 vs Group 3, P = 0.018). The improvement in dyspepsia(Group 1 vs Group 2, P < 0.05; Group 1 vs Group 3, P < 0.05; Group 1 vs Group 4, P < 0.01) and psychological symptom scores(anxiety: Group 1 vs Group 2, P < 0.01; Group 1 vs Group 3, P < 0.05; Group 1 vs Group 4, P < 0.01; depression: Group 1 vs Group 2, P < 0.01; Group 1 vs Group 3, P < 0.01; Group 1 vs Group 4, P < 0.01) in Group 1 were greater than those in Groups 2-4. The compliance indices were positively correlated with the reduction in symptom scores in Groups 1-3. CONCLUSION: Appropriate clinician-patient communication regarding the reasons for prescribing psychoactive drugs that emphasizes both the psychological and GI mechanisms might improve adherence to FM in patients with FD.Xiu-Juan Yan Wen-Ting Li Xin Chen Er-Man Wang Qing Liu Hong-Yi Qiu Zhi-Jun Cao Sheng-Liang Chen 2015World Journal of Gastroenterology2015,21,15:23
4The Reference Genome Sequence of Scutellaria baicalensis Provides Insights into the Evolution of Wogonin Biosynthesis显示文摘Scutellaria baicalensis Georgi is important in Chinese traditional medicine where preparations of dried roots,'Huang Qin,' are used for liver and lung complaints and as complementary cancer treatments. We report a high-quality reference genome sequence for S. baicalensis where 93% of the 408.14-Mb genome has been assembled into nine pseudochromosomes with a super-N50 of 33.2 Mb. Comparison of this sequence with those of closely related species in the order Lamiales, sesamum indicum and Salvia splendens,revealed that a specialized metabolic pathway for the synthesis of 4'-deoxyflavone bioactives evolved in the genus Scu-tellaria. We found that the gene encoding a specific cinnamate coenzyme A ligase likely obtained its newfunc- tion following recent mutations, and that four genes encoding enzymes in the 4'-deoxyflavone pathway are present as tandem repeats in the genome of S. baicalensis. Further analyses revealed that gene duplications, segmental duplication, gene amplification, and point mutations coupled to gene neo- and subfunctionaliza-tions were involved in the evolution of 4'-deoxyflavone synthesis in the genus Scutellaria. Our study not only provides significant insight into the evolution of specific flavone biosynthetic pathways in the mint family, Lamiaceae, but also will facilitate the development of tools for enhancing bioactive productivity by metabolic engineering in microbes or by molecular breeding in plants. The reference genome of S. baicalensis is also useful for improving the genome assemblies for other members of the mint family and offers an important foundation for decoding the synthetic pathways of bioactive compounds in medicinal plants.Qing Zhao Jun Yang Meng-Ying Cui Jie Liu Yumin Fang Mengxiao Yan Wenqing Qiu Huiwen Shang Zhicheng Xu Reheman Yidiresi Jing-Ke Weng Tomas Pluskal Marielle Vigouroux Burkhard Steuernagel Yukun Wei Lei Yang Yonghong Hu Xiao-Ya Chen Cathie Martin 2019Molecular Plant2019,12,7:23
5Porphyrin-like Fe-N4 sites with sulfur adjustment on hierarchical porous carbon for different rate-determining steps in oxygen reduction reaction显示文摘We developed a strategy based on coordination polymer to synthesize singleatom site Fe/N and S-codoped hierarchical porous carbon (Fe1/N,S-PC).The as-obtained Fe1/N,S-PC exhibited superior oxygen reduction reaction (ORR) performance with a half-wave potential (Ev2,0.904 V vs.RHE) that was better than that of commercial Pt/C (E1/2,0.86 V vs.RHE),single-atom site Fe/N-doped hierarchical porous carbon (Fe1/N-PC) without S-doped (E1/2,0.85 V vs.RHE),and many other nonprecious metal catalysts in alkaline medium.Moreover,the Fe1/N,S-PC revealed high methanol tolerance and firm stability.The excellent electrocatalytic activity of Fe1/N,S-PC is attributed to the synergistic effects from the atomically dispersed porphyrin-like Fe-N4 active sites,the heteroatom codoping (N and S),and the hierarchical porous structure in the carbon materials.The calculation based on density functional theory further indicates that the catalytic performance of Fe1/N,S-PC is better than that of Fe1/N-PC owing to the sulfur doping that yielded different rate-determining steps.Konglin Wu Xin Chen Shoujie Liu Yuan Pan Weng-Chon Cheong Wei Zhu Xing Cao Rongan Shen Wenxing Chen Jun LUO Wensheng Yan Lirong Zheng Zheng Chen Dingsheng Wang Qing Peng Chen Chen Yadong Li 2018Nano Research2018,11,12:18

METHODS: One hundred and eighty SD rats were randomly assigned to the model group, Baicalin-treated group, octreotide-treated group and sham operation group. The mortality, plasma endotoxin level, contents of blood urea nitrogen (BUN), creatinine (CREA), phospholipase A2 (PLA2), nitrogen monoxide (NO), tumor necrosis factor (TNF)-α, IL-6 and endothelin-1 (ET-1) in serum, expression levels of renal Bax and Bcl-2 protein, apoptotic indexes and pathological changes of kidney were observed at 3, 6 and 12 h after operation. RESULTS: The renal pathological changes were milder in treated group than in model group. The survival at 12 h and renal apoptotic indexes at 6 h were significantly (P < 0.05) higher in treated group than in model group [66.67% vs 100%; 0.00 (0.02)% and 0.00 (0.04)% vs 0.00 (0.00)%, respectively]. The serum CREA content was markedly lower in octreotide-treated group than in model group at 3 h and 6 h (P < 0.01, 29.200 ± 5.710 μmol/L vs 38.400 ± 11.344 μmol/L; P < 0.05, 33.533 ± 10.106 μmol/L vs 45.154 ± 17.435 μmol/L, respectively). The expression level of renal Bax protein was not significantly different between model group and treated groups at all time points. The expression level of renal Bcl-2 protein was lower in Baicalin-treated group than in model group at 6 h [P < 0.001, 0.00 (0.00) grade score vs 3.00 (3.00) grade score]. The Bcl-2 expression level was lower in octreotide-treated group than in model group at 6 h and 12 h [P < 0.05, 0.00 (0.00) grade score vs 3.00 (3.00) grade score; 0.00 (0.00) grade score vs 0.00 (1.25) grade score, respectively]. The serum NO contents were lower in treated groups than in model group at 3 h and 12 h [P < 0.05, 57.50 (22.50) and 52.50 (15.00) μmol/L vs 65.00 (7.50) μmol/L; P < 0.01, 57.50 (27.50) and 45.00 (12.50) μmol/L vs 74.10 (26.15) μmol/L, respectively]. The plasma endotoxin content and serum BUN content (at 6 h and 12 h) were lower in treated groups than in model group. The contents of IL-6, ET-1, TNF-α (at 6 h) and PLA2 (at 6 h and 12 h) were lower in treated groups than in model group [P < 0.001, 3.031 (0.870) and 2.646 (1.373) pg/mL vs 5.437 (1.025) pg/mL; 2.882 (1.392) and 3.076 (1.205) pg/mL vs 6.817 (0.810) pg/mL; 2.832 (0.597) and 2.462 (1.353) pg/mL vs 5.356 (0.747) pg/mL; 16.226 (3.174) and 14.855 (5.747) pg/mL vs 25.625 (7.973) pg/mL; 18.625 (5.780) and 15.185 (1.761) pg/mL vs 24.725 (3.759) pg/mL; 65.10 (27.51) and 47.60 (16.50) pg/mL vs 92.15 (23.12) pg/mL; 67.91 ± 20.61 and 66.86 ± 22.10 U/mL, 63.13 ± 26.31 and 53.63 ± 12.28 U/mL vs 101.46 ± 14.67 and 105.33 ± 18.10 U/mL, respectively]. CONCLUSION: Both Baicalin and octreotide can protect the kidney of rats with severe acute pancreatitis. The therapeutic mechanisms of Baicalin and octreotide might be related to their inhibition of inflammatory mediators and induction of apoptosis. Baicalin might be a promising therapeutic tool for severe acute pancreatitis.Xi-Ping Zhang Hua Tian Yue-Hong Lai Li Chen Ling Zhang Qi-Hui Cheng Wei Yan Yun Li Qing-Yu Li Qing He Fei Wang 2007World Journal of Gastroenterology2007,13,38:17

11Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability.Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang 2021Signal Transduction and Targeted Therapy2021,6,3:13
12Serum Uric Acid is Associated with the Predicted Risk of Prevalent Cardiovascular Disease in a Community-dwelling Population without Diabetes显示文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.CHENG Di DU Rui WU Xue Yan LIN Lin PENG Kui MA Li Na XU Yu XU Min CHEN Yu Hong BI Yu Fang WANG Wei Qing DAI Meng LU Jie Li 2018Biomedical and Environmental Sciences2018,31,2:13
13Coordinated Transcriptional Regulation by the UVB Photoreceptor and Multiple Transcription Factors for Plant UV-B Responses显示文摘Non-damaging ultraviolet B(UV-B)light promotes photomorphogenic development and stress acclimation through UV-B-specific signal transduction in Arabidopsis.UV-B irradiation induces monomerization and nuclear translocation of the UV-B photoreceptor UV RESISTANCE LOCUS 8(UVR8).However,it is not clear how the nuclear localization of UVR8 leads to changes in global gene expression.Here,we reveal that nuclear UVR8 governs UV-B-responsive transcriptional networks in concert with several previously known transcription factors,including ELONGATED HYPOCOTYL 5(HY5)and PHYTOCHROME INTERACTING FACTOR 4(PIF4).Based on the transcriptomic analysis,we identify MYB13 as a novel positive regulator in UV-B-induced cotyledon expansion and stress acclimation.MYB13 is UV-B inducible and is predominantly expressed in the cotyledons.Our results demonstrate that MYB13 protein functions as a transcription factor to regulate the expression of genes involved in auxin response and flavonoid biosynthesis through direct binding with their promoters.In addition,photoactivated UVR8 interacts with MYB13 in a UV-B-dependent manner and differentially modulates the affinity of MYB13 with its targets.Taken together,our results elucidate the cooperative function of the UV-B photoreceptor UVR8 with various transcription factors in the nucleus to orchestrate the expression of specific sets of downstream genes and,ultimately,mediate plant responses to UV-B light.Chongzhen Qian Zhiren Chen Qing Liu Weiwei Mao Yanling Chen Wei Tian Yan Liu Jiupan Han Xinhao Ouyang Xi Huang 2020Molecular Plant2020,13,5:13

15A bi-directional gap model for simulating the directional thermal radiance of row crops显示文摘Row crops are a kind of typical vegetation canopy between discrete canopy and continuous canopy. Kimes et al. studied the directional thermal radiation of row crops using the geometrical optical model, which simplified row structure as 'box' and neglected the gap among foliage and did not consider the emissivity effects. In this work we take account of the gaps along illumination and viewing directions and propose a bi-direction gap model on the basis of the idea of gap probability of discrete vegetation canopy introduced by 'Li-Strahler' and inter-correlation of continuous vegetation developed by Kuusk. It can be used to explain 'hot spot' effects in thermal infrared region.

17Efficacy of mosapride plus proton pump inhibitors for treatment of gastroesophageal reflux disease: A systematic review显示文摘AIM:To assess the potential benefits of mosapride plus proton pump inhibitors(PPIs)in the treatment of gastroesophageal reflux disease.METHODS:A literature search was performed through MEDLINE,EMBASE,and the ISI Web of Knowledge.The clinical trials that compared the benefit of mosapride plus PPI treatment with that of PPI monotherapy were analyzed.The rate of responders was evaluated by the pooled relative risk(PRR)and improvement in symptom scores was assessed by single effect size of a standardized mean,while Hedges’g was used as the effect size.Pooled effect sizes with 95%CIs were calculated using a fixed-effects model.Between-study heterogeneity was assessed using Q test and I2analyses.In addition,studies that assessed the additional efficacy of mosapride in PPI-resistant patients were also reviewed.RESULTS:This systematic review included information on a total of 587 patients based on 7 trials.Four trials compared the efficacy of combination therapy of mosapride plus a PPI with that of PPI monotherapy.The statistical analysis for the effect of additional mosapride showed equivocal results(PRR=1.132;95%CI:0.934-1.372;P=0.205;Hedges’g=0.24;95%CI:0.03-0.46;P=0.023).No heterogeneity and publication bias were found among the studies.Three openlabeled trials assessed the additional efficacy of mosapride in PPI-resistant patients.However,since these trials did not set the control group,the results may be considerably biased.CONCLUSION:Mosapride combined therapy is not more effective than PPI alone as first-line therapy.Whether it is effective in PPI-resistant patients needs to be determined.Qing Liu Chen-Chen Feng Er-Man Wang Xiu-Juan Yan Sheng-Liang Chen 2013World Journal of Gastroenterology2013,19,47:12
18Allergy-related Evidences in Relation to Serum IgE:Data from the China State Key Laboratory of Respiratory Disease,2008-2013显示文摘Objective To investigate the serum total IgE(tlgE) and specific IgE(slgE) to common allergens among allergic patients in Guangzhou,China.Methods 7 085 patients were examined for tlgE and slgE to 15 allergens,based on the protocols of reversed enzyme allergosorbent test and the sandwich enzyme-linked immunosorbent assay.Results 3 758(53.04%) patients tested positive for tlgE,and 4 640(65.49%) for slgE.Der pteronyssinus,Der farinae,eggs,and cow's milk were the most common allergens leading to higher positive rates of slgE responses.Several peaks of sensitization were:Der pteronyssinus,Der farinae,and Blomia tropicalis at age 10-12;cow's milk at age below 3;eggs at age 4-6.The mean level and positive rate of tlgE tended to increase in subjects sensitized to more allergens.Sensitization to Der pteronyssinus(OR,1.6;P<0.05),Der farinae(OR,1.5;P<0.05),Blomia tropicalis(OR,1.4;P<0.05),Blattella germanica(OR,1.5;P<0.05),cow's milk(OR,1.3;P<0.05),and soy beans(OR,2.0;P<0.05) were independently correlated with allergy-related conditions in preliminary diagnosis.Conclusion The major allergens in Guangzhou include Der pteronyssinus,Der farinae,cow's milk,and eggs.Sensitization to these allergens appears to be predictors of allergy-related disorder.SUN Bao Qing CHEN De Hui ZHENG Pei Yan HUANG Hui Min LUO Wen Ting ZENG Guang Qiao ZHANG Xiao Wen 2014Biomedical and Environmental Sciences2014,27,7:11
19Investigation on Work-Related Musculoskeletal Disorders--China, 2018−2019显示文摘What is already known about this topic?Work-related musculoskeletal disorders(WMSDs)have a high prevalence and seriously harmful,which has attracted extensive attention in various countries in the world.Currently,the occurrence and rules of WMSDs in key industries are not known in China.What is added by this report?The prevalence of WMSDs is relatively high among professional populations in key industries in China,with the most commonly affected body parts concentrated in neck,shoulders,and low back and increasing with age and working years.What are the implications for public health practice?This study determined the prevalence and distribution characteristics of WMSDs in key industries in China and provided scientific evidence to recommend for inclusion of WMSDs in the new revision of the list of occupational diseases in China.Ning Jia Huadong Zhang Ruijie Ling Yimin Liu Gang Li Zaoliang Ren Yan Yin Hua Shao Hengdong Zhang Bing Qiu Meibian Zhang Dayu Wang Qiang Zeng Rugang Wang Jianchao Chen Danying Zhang Liangying Mei Yongquan Liu Jixiang Liu Chengyun Zhang Tianlai Li Qing Xu Ying Qu Xueyan Zhang Xin Sun Zhongxu Wang 2020China CDC weekly2020,2,18:11
20Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11
