[作者:Mathas, S; Misteli, T,期刊:Cell, 页码:1047-1049 , 文章类型: Editorial Material,,卷期:2009年139-6]
- Transcription is obviously essential, but even a good thing can be dangerous at times. In this issue, Lin et al. (2009) provide evidence that binding of the transcription machinery may predispose genome regions to breaka...
- During Transitions Proteins Make Fleeting Bonds
[作者:Boehr, DD,期刊:Cell, 页码:1049-1051 , 文章类型: Editorial Material,,卷期:2009年139-6]

[作者:Sinclair, A; Smith, C,期刊:Cell, 页码:1051-1053 , 文章类型: Editorial Material,,卷期:2009年139-6]
- Conventional wisdom holds that the ovary and testis are terminally differentiated organs in adult mammals. However, Uhlenhaut et al. (2009) now report that deletion of a single gene, Foxl2, is sufficient to induce transd...
- A Tethering Complex Recruits SNAREs and Grabs Vesicles
[作者:Schmitt, HD; Jahn, R,期刊:Cell, 页码:1053-1055 , 文章类型: Editorial Material,,卷期:2009年139-6]
- Protein tethers can bridge gaps between membranes. Ren et al. (2009) now provide evidence that the yeast Dsl1 complex tethers vesicles to the endoplasmic reticulum (ER) by binding ER SNARE proteins at its base and captur...
- Wnt Signaling and the Polarity of the Primary Body Axis
[作者:Petersen, CP; Reddien, PW,期刊:Cell, 页码:1056-1068 , 文章类型: Review,,卷期:2009年139-6]
