    Description: Insulin-like growth factor 1 (IGF-1) induces skeletal muscle maturation and enlargement (hypertrophy). These responses require protein synthesis and myofibril formation (myofibrillogenesis). However, the signaling mechanisms of myofibrillogenesis remain obscure. We found that IGF-1-induced phosphatidylinositol 3-kinase-Akt signaling formed a complex of nebulin and N-WASP at the Z bands of myofibrils by interfering with glycogen synthase kinase-3beta in mice. Although N-WASP is known to be an activator of the Arp2/3 complex to form branched actin filaments, the nebulin-N-WASP complex caused actin nucleation for unbranched actin filament formation from the Z bands without the Arp2/3 complex. Furthermore, N-WASP was required for IGF-1-induced muscle hypertrophy. These findings present the mechanisms of IGF-1-induced actin filament formation in myofibrillogenesis required for muscle maturation and hypertrophy and a mechanism of actin nucleation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takano, Kazunori -- Watanabe-Takano, Haruko -- Suetsugu, Shiro -- Kurita, Souichi -- Tsujita, Kazuya -- Kimura, Sumiko -- Karatsu, Takashi -- Takenawa, Tadaomi -- Endo, Takeshi -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1536-40. doi: 10.1126/science.1197767.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Graduate School of Science, Chiba University, 1-33 Yayoicho, Inageku, Chiba 263-8522, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148390" target="_blank"〉PubMed〈/a〉

    Description: A hallmark of mitosis is the appearance of high levels of histone phosphorylation, yet the roles of these modifications remain largely unknown. Here, we demonstrate that histone H3 phosphorylated at threonine 3 is directly recognized by an evolutionarily conserved binding pocket in the BIR domain of Survivin, which is a member of the chromosomal passenger complex (CPC). This binding mediates recruitment of the CPC to chromosomes and the resulting activation of its kinase subunit Aurora B. Consistently, modulation of the kinase activity of Haspin, which phosphorylates H3T3, leads to defects in the Aurora B-dependent processes of spindle assembly and inhibition of nuclear reformation. These findings establish a direct cellular role for mitotic histone H3T3 phosphorylation, which is read and translated by the CPC to ensure accurate cell division.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, Alexander E -- Ghenoiu, Cristina -- Xue, John Z -- Zierhut, Christian -- Kimura, Hiroshi -- Funabiki, Hironori -- GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249-01/GM/NIGMS NIH HHS/ -- R01 GM075249-02/GM/NIGMS NIH HHS/ -- R01 GM075249-03/GM/NIGMS NIH HHS/ -- R01 GM075249-04/GM/NIGMS NIH HHS/ -- R01 GM075249-05/GM/NIGMS NIH HHS/ -- R01 GM075249-05S1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):235-9. doi: 10.1126/science.1189505.

    Description: We identified a strong temporal correlation between three distinct types of slow earthquakes distributed over 100 kilometers along the dip of the subducting oceanic plate at the western margin of the Nankai megathrust rupture zone, southwest Japan. In 2003 and 2010, shallow very-low-frequency earthquakes near the Nankai trough as well as nonvolcanic tremor at depths of 30 to 40 kilometers were triggered by the acceleration of a long-term slow slip event in between. This correlation suggests that the slow slip might extend along-dip between the source areas of deeper and shallower slow earthquakes and thus could modulate the stress buildup on the adjacent megathrust rupture zone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirose, Hitoshi -- Asano, Youichi -- Obara, Kazushige -- Kimura, Takeshi -- Matsuzawa, Takanori -- Tanaka, Sachiko -- Maeda, Takuto -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1502. doi: 10.1126/science.1197102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Research Institute for Earth Science and Disaster Prevention, 3-1 Tennodai, Tsukuba, Ibaraki 305-0006, Japan. hirose@bosai.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148384" target="_blank"〉PubMed〈/a〉

    Description: Determining the structure of subduction zones is important for understanding mechanisms for the generation of interplate phenomena such as megathrust earthquakes. The peeling off of the uppermost part of a subducting slab and accretion to the bottom of an overlying plate (underplating) at deep regions has been inferred from exhumed metamorphic rocks and deep seismic imaging, but direct seismic evidence of this process is lacking. By comparing seismic reflection profiles with microearthquake distributions in central Japan, we show that repeating microearthquakes occur along the bottom interface of the layer peeling off from the subducting Philippine Sea plate. This region coincides with the location of slow-slip events that may serve as signals for monitoring active underplating.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, Hisanori -- Takeda, Tetsuya -- Obara, Kazushige -- Kasahara, Keiji -- New York, N.Y. -- Science. 2010 Jul 9;329(5988):210-2. doi: 10.1126/science.1187115.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Research Institute for Earth Science and Disaster Prevention (NIED), 3-1 Tennodai, Tsukuba, Ibaraki 305-0006, Japan. kimura@bosai.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20616277" target="_blank"〉PubMed〈/a〉
