| 1 | The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body. | Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid | 2019 | Genes & Diseases2019，6，3： | 15 |
| 2 | Current protective strategies in liver surgery显示文摘During liver resection surgery for cancer or liver transplantation,the liver is subject to ischaemia (reduction in blood flow) followed by reperfusion (restoration of blood flow),which results in liver injury [ischemiareperfusion (IR) or IR injury]. Modulation of IR injury can be achieved in various ways. These include hypothermia,ischaemic preconditioning (IPC) (brief cycles of ischaemia followed by reperfusion of the organ before the prolonged period of ischaemia i.e. a conditioning response),ischaemic postconditioning (conditioning after the prolonged period of ischaemia but before the reperfusion),pharmacological agents to decrease IR injury,genetic modulation of IR injury,and machine perfusion (pulsatile perfusion). Hypothermia decreases the metabolic functions and the oxygen consumption of organs. Static cold storage in University of Wisconsin solution reduces IR injury and has prolonged organ storage and improved the function of transplanted grafts. There is currently no evidence for any clinical advantage in the use of alternate solutions for static cold storage. Although experimental data from animal models suggest that IPC,ischaemic postconditioning,various pharma-cological agents,gene therapy,and machine perfusion decrease IR injury,none of these interventions can be recommended in clinical practice. This is because of the lack of randomized controlled trials assessing the safety and efficacy of ischaemic postconditioning,gene therapy,and machine perfusion. Randomized controlled trials and systematic reviews of randomized controlled trials assessing the safety and efficacy of IPC and various pharmacological agents have demonstrated biochemical or histological improvements but this has not translated to clinical benefit. Further well designed randomized controlled trials are necessary to assess the various new protective strategies in liver resection. | Kurinchi S Gurusamy Hector D Gonzalez Brian R Davidson | 2010 | World Journal of Gastroenterology2010，16，48： | 7 |
| 3 | Secreted protein acidic and rich in cysteine(SPARC)induces epithelial-mesenchymal transition,enhancing migration and invasion,and is associated with high Gleason score in prostate cancer显示文摘Secreted protein acidic and rich in cysteine(SPARC)is a matricellular protein highly expressed in bone tissue that acts as achemoattractant factor promoting the arrival of prostate cancer(PCa)cells to the bone marrow.However,the contribution of SPARCduring the early stages of tumor progression remains unclear.In this study,we show that SPARC is highly expressed in PCa tissueswith a higher Gleason score.Through stable knockdown and overexpression of SPARC in PC3 and LNCaP cells,respectively,here wedem on strate that en doge nous SPARC induces the epithelial-mesenchymal tran sition(EMT),decreasing E-cadheri n and cytokeratin18 and increasing N-cadheri n and vime ntin.Moreover,SPARC in duces the expression of EMT regulatory tran scription factors Snailfamily transcriptional repressor 1(Snail),Snail family transcriptional repressor 2(Slug),and zinc finger E-box binding homeobox 1(Zeb1).In addition,SPARC knockdown in PC3 cells decreases migration and invasion in vitro,without modifying cell proliferation.Our results indicate that SPARC might facilitate tumor progression by modifying the cellular phenotype in cancer cells. | Fernanda Lopez-Moncada Maria Jose Torres Enrique A Castellon Hector R Contreras | 2019 | Asian Journal of Andrology2019，21，6： | 5 |
| 4 | The transcription factor ZEB1 promotes chemoresistance in prostate cancer cell lines显示文摘One of the factors promoting tumoral progress is the abnormal activation of the epithelial-mesenchymal transition(EMT)program which has been associated with chemoresistance in tumoral cells.The transcription factor zinc finger E-box-binding homeobox 1(ZEB1),a key EMT activator,has recently been related to docetaxel resistance,the main chemotherapeutic used in advanced prostate cancer treatment.The mechanisms involved in this protective effect are still unclear.In a previous work,we demonstrated that ZEB1 expression induced an EMT-like phenotype in prostate cancer cell lines.In this work,we used prostate cancer cell lines 22Rvl and DU145 to study the effect of ZEB1 modulation on docetaxel resistance and its possible mechanisms.The results showed that ZEB1 overexpression conferred to 22Rvl cell resistance to docetaxel while its silencing made DU145 cells more sensitive to it.Analysis of resistance markers showed no presenee of ATP-binding cassette subfamily B member 1(MDR1)and no changes in breast cancer resistance protein(BCRP)or ATP-binding cassette subfamily C member 10(MRP7).However,a correlation between ZEB1,multidrug resistance-associated protein 1(MRP1),and ATP-binding cassette subfamily C member 4(MRP4)expression was observed.MRP4 inhibition,using MK571,resensitized cells with ZEB1 overexpression to docetaxel treatment.In addition,modulation of ZEB1 and subsequent change in MRP4 expression correlated with a lower apoptotic response to docetaxel,characterized by lower B-cell lymphoma 2(Bcl2),high BCL2-associated X protein(Bax),and high active caspase 3 expression.The response to docetaxel in our model seems to be mediated mainly by activation of the apoptotic death program.Our results showed that modulation of MRP4 could be a mediator of ZEBl-related resistance to docetaxel in prostate cancer,making it a possible marker for chemotherapy response in patients who do not express MDR1. | Octavio Orellana-Serradell Daniela Herrera Enrique A Castellon Hector R Contreras | 2019 | Asian Journal of Andrology2019，21，5： | 5 |

| 6 | syndecan-1和-2表达形式的变化可以预测前列腺癌生化复发显示文摘前列腺癌的临床特点不能准确确定患者是否会发生生化复发,因而不适合作为预后和复发的指标。需要新的分子标记物对患者进行适当的术前风险分层。本研究旨在评估syndecan-1和-2的表达改变是否可以预测临床局限性前列腺癌患者行前列腺根治术后的生化复发。取60份局限性前列腺癌患者的石蜡包埋组织标本,采用免疫组化染色检测syndecan-1和-2的表达。取10份良性前列腺增生患者的样本作为非恶性对照。利用半定量分析,对其进行染色评估。为探讨预后效果,用Kaplan—Meier生存曲线进行分析,并进行log—rank检验。在良性前列腺样本中,syndecan-1在基底层上皮细胞中有表达,在上皮分泌细胞的基侧膜上也有表达;syndecan-2则主要但挞底层上皮细胞中表达。前列腺癌样本中,两种syndecan的表达模式都转变成定位在颗粒状细胞质上。生存分析显示,在游离前列腺特异性抗原(fPSA)复发存活曲线中,正常和改变的syndecan-1和-2的表达存在显著差异(P〈0.05)。这些数据表明,syndecan—1和-2可以作为临床局灶性前列腺癌患者预后的标记物,从而改进前列腺特异性抗原(PSA)评估复发风险,增加风险分层。 | Rodrigo Ledezma Federico Cifuentes Ivan Gallegos Juan Fulla Enrique Ossandon Enrique A Castellon Hector R Contreras | 2011 | Asian Journal of Andrology2011，13，3： | 2 |
