| 1 | Destabilization of linker histone H1.2 is essential for ATM activation and DNA damage repair显示文摘连接器 histone H1 在 DNA 损坏反应是更高的顺序染色质结构,而是它的参与的一个主人管理者,修理是不清楚的。这里,我们报导连接器 histone H1.2 是混乱毛细管扩张的一个必要管理者变异(ATM ) 激活。我们证明 H1.2 通过和 ATM 热重复领域和 MRE11-RAD50-NBS1 (MRN ) 的抑制的直接相互作用保护染色质免受异常 ATM 激活的伤害复杂依赖者的 ATM 招募。在 DNA 损坏之上, H1.2 通过它的 C 终点和进一步的 proteasomal 降级的 poly-ADP-ribosylation (PARylation ) 经历快速的 PARP1 依赖的染色质分离。由 PARylation 死了的变化妥协 ATM 激活和 DNA 损坏修理的 PARP1 弄空或 H1.2 的 H1.2 排水量的抑制,因此导致损害了房间幸存。一起拿,我们的调查结果建议连接器 histone H1.2 作为一个生理的障碍工作因为指向染色质的 ATM,和调停 PARylation 的活跃 H1.2 周转为柔韧的 ATM 激活和 DNA 损坏修理被要求。 | Zhiming Li Yinglu Li Ming Tang Bin Peng Xiaopeng Lu Qiaoyan Yang Qian Zhu Tianyun Hou Meiting Li Chaohua Liu Lina Wang Xingzhi Xu Ying Zhao Haiying Wang Yang Yang Wei-Guo Zhu | 2018 | Cell Research2018，28，7： | 3 |
| 2 | MiR-430 Can Affect the Mesoderm Formation and Metamorphosis of Paralichthys olivaceus by Targeting lefty Gene显示文摘MiR-430 is a non-coding small RNA that participates in early embryonic development by acting on the Nodal signaling pathway.Its functions in Paralichthys olivaceus(P.olivaceus),however,remain unclear.In this study,through biological information technology,we hypothesized lefty was the target gene of miR-430.Lefty is a divergent member of the transforming growth factor-β(TGF-β)superfamily,and is involved in regulating left-right patterning as an antagonist of the Nodal signaling pathway.To study the relationship between miR-430 and lefty gene,miR-430 and fluorescent expression vector were transfected into embryo cells.Our results showed that miR-430 has important effects on early embryonic development.It can inhibit the expressions of lefty and other genes related to Nodal signaling pathway.Additionally,the expression of miR-430 was involved in the metamorphosis of P.olivaceus.This study clarifies the function of miR-430 in P.olivaceus,which will be helpful for further research on the interactions between miR-430 and the Nodal signaling pathway. | LI Rui WANG Zhenwei SUN Minmin PENG Meiting QI Jie WANG Zhigang | 2020 | Journal of Ocean University of China2020，19，2： | 0 |
| 3 | A novel two-dimensional nanoheterojunction via facilitating electron–hole pairs separation for synergistic tumor phototherapy and immunotherapy显示文摘Nanomaterial-mediated phototherapy in tumor treatment has been developed rapidly in the past few years due to its noninvasive character.However,the low energy conversion efficiency and high recombination rate of the photo-triggered electron–hole pairs of single nano-agent limit the phototherapy efficiency.Herein,we constructed a novel two-dimensional nanoheterojunction MoS_(2)-Ti_(3)C_(2)(MT),which allowed a high photothermal conversion efficiency(59.1%)as well as an effective separation of photo-triggered electron–hole pairs for reactive oxygen species(ROS)generation under single 808 nm laser irradiation.Upon the modification of the mitochondrial targeted molecule(3-proxycarboxylic)triphenyl phosphine bromide(TPP)and 4T1 cell membrane,m@MoS_(2)-Ti_(3)C_(2)/TPP(m@MTT)could effectively target to the tumor cell and further locate to the mitochondria to amplify tumor-specific oxidative stress,which not merely effectively inhibits the local tumor growth but also induces tumor immunogenic cell death(ICD)for activating antitumor immune response.Additionally,cytosine guanine dinucleotide(CPG),as a Toll-like receptor 9(TLR9)agonist,was further introduced to the system to boost adaptive immune responses,resulting in improved level of cytotoxic T cells as well as a decrease in the number of regulatory T cells.In vivo antitumor mechanism studies demonstrated that not only the primary and distant tumors in 4T1 bearing-tumor mice model were significantly inhibited,but also the lung metastasis of tumor was effectively suppressed.Therefore,this work revealed the ROS generation mechanism of MT nanoheterojunction and provided a novel strategy to fabricate a biomedically applicable MT nanoheterojunction for tumor treatment. | Xiaoge Zhang Xiaomei Chen Peng Zhang Meiting Li Miao Feng Yaqian Zhang Lili Cheng Junjie Tang Langtao Xu Yadong Liu Zhuoyin Liu Zhong Cao Jie Liu | 2023 | Nano Research2023，16，5： | 0 |
