Xuebiao Yao, Dasheng Li and Gang Pei recently wrote an essay to Nature Review in MCB Which is entitled “In focus: molecular and cell biology research in China”. Here is the link: http://www.nature.com/nrm/journal/v14/n9/full/nrm3638.html In this article, they discussed the past, present and future of molecular and cell biology research in China. One part which interested me is the key MCB discoveries in China. Although most of the work are nice and likely solid work, few of them are breakthroughs in their own fields. How did they select and cite these papers? Here are the examples they mentioned in the article: Signalling Gang Pei and colleagues identified a unique five-transmembrane G protein- coupled receptor (GPCR) implicated in cytokine signalling3. Using GPCRs as a model system, they revealed the spatial dynamics of β-arrestin and its role in epigenetic reprogramming4 and delineated how β-arrestin orchestrates cellular energy homeostasis5. Bacterial– and viral–host interactions Using crystal structure-aided delineation, Zihe Rao and colleagues (at the Institute of Biophysics (IBP)) and Tsinghua University) illustrated the mechanism of action underlying a key protease of the severe acute respiratory syndrome (SARS) virus and its interaction with an inhibitor6. Jijie Chai (National Institute of Biological Sciences (NIBS)) established how the bacterial effector protein AvrPto activates plant immunity7. Furthermore, Nieng Yan and Yigong Shi (both are at Tsinghua University) defined the structural basis of transcription activator-like (TAL) effector –DNA interactions; TAL effectors are secreted by phytopathogenic bacteria and recognize host DNA through a central domain of tandem repeats8. Finally, Feng Shao (NIBS) delineated the host cell response to bacterial virulence, suggesting that bacterial virulence factors rewire the host cell signalling circuitry9. Necroptosis Two independent teams led by Jiahuai Han (Xiamen University) and Xiaodong Wang and Xiaoguang Lei (NIBS) delineated the mechanism underlying necroptosis and discovered chemical inhibitors of this process10, 11. DNA hydroxylation and demethylation The paternal DNA in a zygote undergoes active demethylation before the first mitosis, and Guo-Liang Xu's group from the Institute of Biochemistry and Cell Biology at the Shanghai Institutes for Biological Sciences (IBCB–SIBS; he was also a Chinese Academy of Sciences–Max Planck Society (CAS–MPS) junior group leader at that time) revealed the mechanisms underlying this. They showed that the dioxygenase ten-eleven translocation 3 (TET3) catalyses the oxidation of 5methylcytosine in the paternal genome in mouse zygotes, which results in the generation of 5hydroxymethylcytosine12. They also discovered that the oxidized cytosine can be removed by thymine DNA glycosylase13, thus providing insights into the mechanism of DNA methylation. Acetylation in autophagy and metabolism Using Caenorhabditis elegans, Hong Zhang (who was at the NIBS) identified several unique regulators of autophagy14. Li Yu and Sheng-Cai Lin, who are at Tsinghua University and Xiamen University, respectively, independently unravelled how acetylatransferases orchestrate autophagy dynamics through the acetylation of effector proteins on Lys residues15, 16. Using a proteomics-based approach, Guoping Zhao, Shimin Zhao and their colleagues (Fudan University) identified an acetylome underlying the regulation of liver cell metabolism and illustrated the potential signalling cascades involved in liver cell homeostasis17, 18. Stem cells The groups of Jinsong Li (IBCB-SIBS) and Qi Zhou (Institute of Zoology in Beijing, CAS) generated transgenic mice using androgenetic haploid embryonic stem (AG-haES) cells21, 22. Haploid cells are versatile and are easy to genetically manipulate. Independently, both research groups established mouse AG-haES cells by transferring sperm into an enucleated oocyte. They also used AG-haES cells to produce live animals via injection into oocytes. Duanqing Pei (Guangzhou Institutes of Biomedicine and Health) showed that mesenchymal-to-epithelial transition is required for reprogramming fibroblasts into induced pluripotent stem cells19. The reprogramming factors for inducing pluripotency were primarily identified from ES cell-enriched, pluripotency-associated factors. However, recent developments from the laboratories of Hongkui Deng and Chao Tang (Peking University) show that mesendodermal lineage specification factors could cooperate with ectodermal specification factors to reprogramme mouse somatic cells to the pluripotent state in the absence of exogenous OCT4 (also known as POUF51 and OCT3) and SOX2 (Ref. 20). Structral insights The group of Jia-Wei Wu recently carried out a structure–function analyses to elucidate AMP-activated protein kinase (AMPK) activation23, and Yigong Shi's group used a structural biology-based approach to identify a membrane transporter24. Both of these groups are at Tsinghua University. In addition, structure-based studies, carried out by Mingjie Zhang (Fudan University and Hong Kong University of Science and Technology Research Consortium), showed that a lipid-induced conformational switch controls the activity of the SNARE YKT6 (Ref. 25).

made in China的?在国内问问吧。。。。上次一个朋友说买的一个中国产的汽车配件 ,收到了发现尺寸不匹配,最后只好掏钱买美国产的。

按说木头件应该都是美国本土加工的。不管了,打电话去骚扰房子原先的builder试试 看。
