| 1 | Mitochondrial H2O2 generated from electron transport chain complex I stimulates muscle differentiation显示文摘Mitochondrial 反应的氧种类(mROS ) 被认为有害到房间。然而,他们的生理的角色一直不作为表明调停人是彻底地探索了。这里,我们调查了 mROS 是否从 mitochondrial 电子运输链(mETC ) 产生了复杂我刺激了肌肉区别。我们的结果证明 mROS 的数量被增加并且锰 superoxide dismutase (MnSOD ) 在肌肉区别期间经由 NF-B 激活被导致。指向线粒体的抗氧化剂(MitoQ 和 MitoTEMPOL ) 和指向线粒体的过氧化氢酶减少了没有影响 ATP 的数量的 mROS 数量和压制的肌肉区别。Mitochondrial 改变包括在线粒体的数字和尺寸的 mitochondrial 抄写因素 A 和增加的正式就职,并且功能的激活在肌肉区别期间被观察。特别地,增加了 mETC 建筑群的表示层次我子单元和建筑群的一项更高的活动我比另外的建筑群被观察。毒鱼藤素, mETC 建筑群的一个禁止者我,减少 mitochondrial NADH/NAD+ 比率和 mROS 层次在肌肉区别期间。mROS 铺平的我用小介入 RNA 和毒鱼藤素减少了的建筑群的抑制,压制的肌肉区别,和有伴随物的弄空的 ATP 层次在 glycolysis 增加。从这些结果,我们结束那复杂我导出 | Seonmin Lee Eunyoung Tak Jisun Lee MA Rashid Michael P Murphy Joohun Ha Sung Soo Kim | 2011 | Cell Research2011，21，5： | 4 |
| 2 | Proto-oncogenic H-Ras, K-Ras, and N-Ras are involved in muscle differentiation via phosphatidylinositol 3-kinase显示文摘Oncogenic H 地岬 G12V 和它的变体被显示了禁止肌肉区别。然而,在肌肉区别的 proto-oncogenic 地岬(c 地岬) 的角色仍然保持不清楚。地岬的活跃 GTP 固定的形式包括 Raf, phosphatidylinositol 3-kinase (PI3K ) , Ral-GDS,和播送下游的信号的另外的分子与多样的受动器为伙伴所知。我们假设那 c 地岬可以由有选择地激活 PI3K 刺激肌肉区别,为肌肉区别的一个重要调停人。在我们的实验,由 farnesyltransferase 禁止者和 H 地岬(地岬 S17N ) 的一种主导的否定形式的 c 地岬的抑制压制了肌肉区别。一致地,由 siRNAs 的 H 地岬, K 地岬,和 N 地岬击倒的个人都堵住了肌肉区别。有趣地,我们发现 c 地岬优先地与 PI3K 而非它的主要有约束力的搭挡 c-Raf 交往,在 myogenic 区别期间,与全部的 c 地岬活动仍然保持未改变。PI3K 和它的下游的 myogenic 小径, Nox2/NF-魏 B /inducible 氮的氧化物 synthase (iNOS ) 小径,被发现被 c 地岬活动的抑制在区别期间压制。而且, PI3K 的一种组成地活跃的形式的表示完全救了区别块并且在 c-Ras-inhibited 房间重新激活 Nox2/NF-魏 B /iNOS 小径。根据我们的结果,我们断定与 oncogenic 地岬相反, proto-oncogenic H 地岬, K 地岬,和 N 地岬直接经由 PI3K 和它的下游的发信号小径涉及肌肉区别的提升。另外, PI3K 小径激活与不同主要激活的 Raf/Mek/Erk 小径的并发的抑制被联系。 | Jisun Lee Kyu Jin Choi Min Jin Lim Feng Hong Tae Gyu Choi Eunyoung Tak Seonmin Lee Young-Joo Kim Sung Goo Chang Jin Man Cho Joohun Ha Sung Soo Kim | 2010 | Cell Research2010，20，8： | 2 |

| 4 | Biomimetic cell-actuated artificial muscle with nanofibrous bundles显示文摘Biohybrid artificial muscle produced by integrating living muscle cells and their scaffolds with free movement in vivo is promising for advanced biomedical applications,including cell-based microrobotic systems and therapeutic drug delivery systems.Herein,we provide a biohybrid artificial muscle constructed by integrating living muscle cells and their scaffolds,inspired by bundled myofilaments in skeletal muscle.First,a bundled biohybrid artificial muscle was fabricated by the integration of skeletal muscle cells and hydrophilic polyurethane(HPU)/carbon nanotube(CNT)nanofibers into a fiber shape similar to that of natural skeletal muscle.The HPU/CNT nanofibers provided a stretchable basic backbone of the 3-dimensional fiber structure,which is similar to aain-myosin scaffolds.The incorporated skeletal muscle fibers contribute to the actuation of biohybrid artificial muscle.In fact,electrical field stimulation reversibly leads to the contraction of biohybrid artificial muscle.Therefore,the current development of cell-actuated artificial muscle provides great potential for energy delivery systems as actuators for implantable medibot movement and drug delivery systems.Moreover,the innervation of the biohybrid artificial muscle with motor neurons is of great interest for human-machine interfaces. | Yongwoo Jang Sung Min Kim Eunyoung Kim Dong Yeop Lee Tong Mook Kang Seon Jeong Kim | 2021 | Microsystems & Nanoengineering2021，7，5： | 0 |
| 5 | Long-term outcomes of endoscopic submucosal dissection and surgery for undifferentiated intramucosal gastric cancer regardless of size显示文摘BACKGROUND The clinical outcomes of endoscopic submucosal dissection(ESD)for undifferentiated(UD)intramucosal early gastric cancer(EGC)compared with those of surgery,regardless of lesion size,are not well known.Furthermore,there is a concern regarding the treatment plan before and after ESD in cases of UD intramucosal EGC within expanded indications.AIM To evaluate clinical outcomes of ESD compared with those of surgery in UD intramucosal EGC patients regardless of tumor size.METHODS We enrolled patients with UD intramucosal EGC after ESD with complete resection or surgery from January 2005 to August 2020 who met the within or beyond expanded indications with lesion size>2 cm(the only non-curative factor).Overall,123 and 562 patients underwent ESD and surgery,respectively.After propensity-score matching,clinical and long-term outcomes,i.e.,recurrencefree survival(RFS)and overall survival(OS),were analyzed.The multivariable Cox proportional hazard model with treatment modality and ESD indication was used to evaluate the recurrence risk.RESULTS After matching,119 patients each were finally enrolled in the ESD and surgery groups.The median length of hospital stay was shorter in the ESD group than surgery group(4.0 vs 9.0 days,P<0.001).Four cases of recurrence after ESD were local recurrences,all of which occurred within 1 year.Total recurrence was seven(5.9%)and two(1.7%)in the ESD and surgery groups,respectively.No difference was observed between the two groups with respect to OS(P=0.948).However,the ESD group had inferior RFS compared with the surgery group(P=0.031).ESD was associated with the risk of recurrence after initial treatment in all enrolled patients(hazard ratio,5.2;95%confidence interval:1.0-25.8,P=0.045).CONCLUSION Although OS was similar between the two groups,surveillance endoscopy was important for the ESD than for the surgery group because RFS was inferior and local recurrence was an issue. | Gil Ho Lee Eunyoung Lee Bumhee Park Jin Roh Sun Gyo Lim Sung Jae Shin Kee Myung Lee Choong-Kyun Noh | 2022 | World Journal of Gastroenterology2022，28，8： | 0 |
