  • An elt-3/elt-5/elt-6 GATA transcription circuit guides aging in C-elegans
    [作者:Budovskaya, YV; Wu, K; Southworth, LK; Min, J; Tedesco, P; Johnson, TE; Kim, SK,期刊:Cell, 页码:291-303 , 文章类型: Article,,卷期:2008年134-2]
  • To define the C. elegans aging process at the molecular level, we used DNA microarray experiments to identify a set of 1294 age-regulated genes and found that the GATA transcription factors ELT-3, ELT-5, and ELT-6 are re...
  • Superoxide flashes in single mitochondria
    [作者:Wang, W; Fang, HQ; Groom, L; Cheng, AW; Zhang, WR; Liu, J; Wang, XH; Li, KT; Han, PD; Zheng, M; Yin, JH; Wang, WD; Mattson, MP; Kao, JPY; Lakatta, EG; Sheu, SS; Ouyang, KF; Chen, J; Dirksen, RT; Cheng, HP,期刊:Cell, 页码:279-290 , 文章类型: Article,,卷期:2008年134-2]
  • In quiescent cells, mitochondria are the primary source of reactive oxygen species (ROS), which are generated by leakiness of the electron transport chain (ETC). High levels of ROS can trigger cell death, whereas lower l...
  • SIRT1 regulates circadian clock gene expression through PER2 deacetylation
    [作者:Asher, G; Gatfield, D; Stratmann, M; Reinke, H; Dibner, C; Kreppel, F; Mostoslavsky, R; Alt, FW; Schibler, U,期刊:Cell, 页码:317-328 , 文章类型: Article,,卷期:2008年134-2]
  • The mammalian circadian timing system is composed of a central pacemaker in the suprachiasmatic nucleus of the brain that synchronizes countless subsidiary oscillators in peripheral tissues. The rhythm-generating mechani...
  • TGF beta in cancer
    [作者:Massague, J,期刊:Cell, 页码:215-230 , 文章类型: Review,,卷期:2008年134-2]
  • The transforming growth factor beta (TGF beta) signaling pathway is a key player in metazoan biology, and its misregulation can result in tumor development. The regulatory cytokine TGF beta exerts tumor-suppressive effec...
  • Costly mistakes: Translational infidelity and protein homeostasis
    [作者:Powers, ET; Balch, WE,期刊:Cell, 页码:204-206 , 文章类型: Article,,卷期:2008年134-2]
  • Protein misfolding is increasingly being recognized as a key process in organismal health and disease. Drummond and Wilke (2008) show that misfolding caused by mistakes during the translation of RNA into proteins (mistra...
