| 1 | The Simultaneous Repression Of CCR and CAD, Two Enzymes of the Lignin Biosynthetic Pathway, Results in Sterility and Dwarfism in Arabidopsis thaliana显示文摘Cinnamoyl CoA reductase (CCR ) 和 cinnamyl 白酒脱氢酶(CAD ) 催化 monolignol 生合成的最后步骤。在 Arabidopsis,一 CCR 基因(CCR1, At1g15950 ) 并且二 CAD 基因(CAD C At3g19450 和 CAD D At4g34230 ) 涉及这条小径。三倍的恶棍 c 恶棍 d ccr1 变异的、命名 ccc,被获得。这异种显示严格的矮子显型和男绝育。在 ccc 的木质素内容成熟的茎被归结为 50% 野类型的水平。另外,茎木质素结构严重地被影响,在抵抗内部单位的契约和加入由戏剧的丰富出现进象 coniferaldehyde 那样的 monolignol 先锋的聚合物 sinapaldehyde,和 ferulic 酸。男绝育由于在花药内层的木质化的缺乏,它引起花药裂开并且花粉版本的失败。ccc hypolignified 茎积累黄酮醇 glycosides, sinapoyl malate 和 feruloyl malate 的更高的数量,它建议酉分的小径的重定向。因此, CAD 和 CCR 的缺席, monolignol 小径的关键酶,比他们中的每的单个缺席在显型上有更严重的后果。另一 CCR 感应(CCR2, At1g80820 ) 并且另一 CAD (CAD1, At4g39330 ) 不补偿主要 CCR 和 CAD 活动的缺席。CCR 和 CAD 活动的这缺乏不仅影响木质化,而且严重地影响植物的发展。当试着减少植物的木质素内容以便便于 lignocellulose-to-bioethanol 变换过程时,这些后果必须小心地被考虑。 | Johanne Thevenin Brigitte Pollet Bruno Letarnec Luc Saulnier Lionel Gissot Alessandra Maia-Grondard Catherine Lapierre Lise Jouanin | 2011 | Molecular Plant2011，4，1： | 18 |
| 2 | Altered Lignin Biosynthesis Improves Cellulosic Bioethanol Production in Transgenic Maize Plants Down-Regulated for Cinnamyl Alcohol Dehydrogenase显示文摘Cinnamyl 白酒脱氢酶(CAD ) 是涉及 monolignol 生合成的最后步的关键酶。木质素生产上的 CAD 下面规定的效果在玉米通过一条转基因的途径被调查。转基因的 CAD-RNAi 植物显示出在房间墙作文取决于分析织物和表演改变的酶的减小的不同的度。没有影响全部的木质素内容, CAD-RNAi 茎的细胞墙在 S-to-G 比率与细微减小包含木质素聚合物。另外,这些房间墙积累纤维素和 arabinoxylans 的高水平。相反, CAD-RNAi 中肋的房间墙在全部的木质素内容并且房间墙多糖介绍减小。,在 vitro degradability,试金显示出那到不同程度, CAD 活动的压抑导致的变化生产了中肋和比野类型的植物更可能减解的茎。在这块地里种的 CAD-RNAi 植物介绍了野类型的显型并且生产了干燥生物资源的更高的数量。有纤维质的 bioethanol 试金表明 CAD-RNAi 生物资源生产了乙醇的高水平与相比野类型,使 CAD 成为一个好目标两个都改进玉米 lignocellulosic 生物资源的营养、精力充沛的值。 | Silvia Fornale Montserrat Capellades Antonio Encina Kan Wang Sami Irara Catherine Lapierre Katia Ruel Jean-Paul Joseleaue Jordi Berenguer Pere Puigdomenech Joan Rigau David Caparros-Ruiz | 2012 | Molecular Plant2012，5，4： | 14 |

| 8 | RIP140 regulates POLK gene expression and the response to alkylating drugs in colon cancer cells显示文摘Aim:The transcription factor RIP140(receptor interacting protein of 140 kDa)is involved in intestinal tumorigenesis.It plays a role in the control of microsatellite instability(MSI),through the regulation of MSH2 and MSH6 gene expression.The aim of this study was to explore its effect on the expression of POLK,the gene encoding the specialized translesion synthesis(TLS)DNA polymeraseκknown to perform accurate DNA synthesis at microsatellites.Methods:Different mouse models and engineered human colorectal cancer(CRC)cell lines were used to analyze by RT-qPCR,while Western blotting and luciferase assays were used to elucidate the role of RIP140 on POLK gene expression.Published DNA microarray datasets were reanalyzed.The in vitro sensitivity of CRC cells to methyl methane sulfonate and cisplatin was determined.Results:RIP140 positively regulates,at the transcriptional level,the expression of the POLK gene,and this effect involves,at least partly,the p53 tumor suppressor.In different cohorts of CRC biopsies(with or without MSI),a strong positive correlation was observed between RIP140 and POLK gene expression.In connection with its effect on POLK levels and the TLS function of this polymerase,the cellular response to methyl methane sulfonate was increased in cells lacking the Rip140 gene.Finally,the association of RIP140 expression with better overall survival of CRC patients was observed only when the corresponding tumors exhibited low levels of POLK,thus strengthening the functional link between the two genes in human CRC.Conclusion:The regulation of POLK gene expression by RIP140 could thus contribute to the maintenance of microsatellite stability,and more generally to the control of genome integrity. | Pascale Palassin Marion Lapierre Sandrine Bonnet Marie-Jeanne Pillaire Balázs Győrffy Catherine Teyssier Stéphan Jalaguier Jean-Sébastien Hoffmann Vincent Cavaillès Audrey Castet-Nicolas | 2022 | Cancer Drug Resistance2022，5，2： | 0 |
