Calcium transients drive cells to discharge prostaglandin E2 (PGE2). We visualized PGE2-induced protein kinase A (PKA) activation and quantitated PGE2 secreted from a single cell by combining fluorescence microscopy and a simulation model. ...
Rab32 and Rab38 maintain bone homeostasis by regulating intracellular traffic in osteoclasts [0.03%]
Rab32和Rab38通过调节破骨细胞内的细胞运输来维持骨稳态
Kanako Tokuda,Shiou-Ling Lu,Zidi Zhang et al.
Kanako Tokuda et al.
Osteoclasts play a crucial role in bone homeostasis by forming resorption pits on bone surfaces, resulting in bone resorption. The osteoclast expression of Rab38 protein is highly induced during differentiation from macrophages. Here we gen...
Signal sequence-triage is activated by translocon obstruction sensed by an ER stress sensor IRE1α [0.03%]
内质网压力感应器IRE1α感应到转位孔通道阻塞激活信号肽序列分类装置
Ashuei Sogawa,Ryota Komori,Kota Yanagitani et al.
Ashuei Sogawa et al.
Secretory pathway proteins are cotranslationally translocated into the endoplasmic reticulum (ER) of metazoan cells through the protein channel, translocon. Given that there are far fewer translocons than ribosomes in a cell, it is essentia...
VAMP5 and distinct sets of cognate Q-SNAREs mediate exosome release [0.03%]
VAMP5和一组相应的Q-SNARE介导外体释放
Takahide Matsui,Yuriko Sakamaki,Shu Hiragi et al.
Takahide Matsui et al.
Small extracellular vesicles (sEVs) are largely classified into two types, plasma-membrane derived sEVs and endomembrane-derived sEVs. The latter type (referred to as exosomes herein) is originated from late endosomes or multivesicular bodi...
IC2 participates in the cooperative activation of outer arm dynein densely attached to microtubules [0.03%]
IC2参与外周臂动力臂的协同活化并密集附着在微管上
Yusuke Kondo,Tomoka Ogawa,Emiri Kanno et al.
Yusuke Kondo et al.
Ciliary outer-arm dynein (OAD) consists of heavy chains (HCs), intermediate chains (ICs), and light chains (LCs), of which HCs are the motor proteins that produce force. Studies using the green alga Chlamydomonas have revealed that ICs and ...
FilGAP, a GAP for Rac1, down-regulates invadopodia formation in breast cancer cells [0.03%]
filgap蛋白通过下调侵袭小体的形成抑制乳腺癌细胞侵袭力的研究
Koji Saito,Sakino Ozawa,Yosuke Chiba et al.
Koji Saito et al.
Invadopodia are protrusive structures that mediate the extracellular matrix (ECM) degradation required for tumor invasion and metastasis. Rho small GTPases regulate invadopodia formation, but the molecular mechanisms of how Rho small GTPase...
Sphingomyelin metabolism underlies Ras excitability for efficient cell migration and chemotaxis [0.03%]
鞘氨醇代谢作用确保Ras的兴奋性以实现高效的细胞迁移和趋化性
Da Young Shin,Hiroaki Takagi,Michio Hiroshima et al.
Da Young Shin et al.
In eukaryotic motile cells, the active Ras (Ras-GTP)-enriched domain is generated in an asymmetric manner on the cell membrane through the excitable dynamics of an intracellular signaling network. This asymmetric Ras signaling regulates pse...
Two coral fluorescent proteins of distinct colors for sharp visualization of cell-cycle progression [0.03%]
两种不同颜色的珊瑚荧光蛋白可清晰地观察细胞周期进程
Ryoko Ando,Asako Sakaue-Sawano,Keiko Shoda et al.
Ryoko Ando et al.
We cloned and characterized two new coral fluorescent proteins: h2-3 and 1-41. h2-3 formed an obligate dimeric complex and exhibited bright green fluorescence. On the other hand, 1-41 formed a highly multimeric complex and exhibited dim red...
Proteomic analysis of fatty liver induced by starvation of medaka fish larvae [0.03%]
斑马鱼饥饿诱导脂肪肝的蛋白质组分析
Tomoyo Ikeda,Tokiro Ishikawa,Satoshi Ninagawa et al.
Tomoyo Ikeda et al.
When medaka fish (Oryzias latipes) larvae are grown in the absence of exogenous nutrition, the liver becomes dark and positive to Oil Red O staining from 7 days post-hatch (dph). We determined the mechanism of this starvation-induced develo...
Zebrafish imaging reveals hidden oncogenic-normal cell communication during primary tumorigenesis [0.03%]
斑马鱼成像揭示原发肿瘤发生过程中隐藏的致癌细胞与正常细胞之间的通讯现象
Yukinari Haraoka,Mai Miyake,Tohru Ishitani
Yukinari Haraoka
Oncogenic mutations drive tumorigenesis, and single cells with oncogenic mutations act as the tumor seeds that gradually evolve into fully transformed tumors. However, oncogenic cell behavior and communication with neighboring cells during ...
