3Sorafenib inhibits growth and metastasis of hepatocellular carcinoma by blocking STAT3显示文摘AIM: To investigate the inhibitory role and the underlying mechanisms of sorafenib on signal transducer and activator of transcription 3 (STAT3) activity in hepatocellular carcinoma (HCC).METHODS: Human and rat HCC cell lines were treated with sorafenib. Proliferation and STAT3 dephosphorylation were assessed. Potential molecular mechanisms of STAT3 pathway inhibition by sorafenib were evaluated. In vivo antitumor action and STAT3 inhibition were investigated in an immunocompetent orthotopic rat HCC model.RESULTS: Sorafenib decreased STAT3 phosphorylationat the tyrosine and serine residues (Y705 and S727), but did not affect Janus kinase 2 (JAK2) and phosphatase shatterproof 2 (SHP2), which is associated with growth inhibition in HCC cells. Dephosphorylation of S727 was associated with attenuated extracellular signal-regulated kinase (ERK) phosphorylation, similar to the effects of a mitogen-activated protein kinase (MEK) inhibitor U0126, suggesting that sorafenib induced S727 dephosphorylation by inhibiting MEK/ERK signaling. Meanwhile, sorafenib could also inhibit Akt phosphorylation, and both the phosphatidylinositol-3-kinase (PI3K) inhibitor LY294002 and Akt knockdown resulted in Y705 dephosphorylation, indicating that Y705 dephosphorylation by sorafenib was mediated by inhibiting the PI3K/Akt pathway. Finally, in the rat HCC model, sorafenib signifi cantly inhibited STAT3 activity, reducing tumor growth and metastasis.CONCLUSION: Sorafenib inhibits growth and metastasis of HCC in part by blocking the MEK/ERK/STAT3 and PI3K/Akt/STAT3 signaling pathways, but independent of JAK2 and SHP2 activation.Fang-Ming Gu, Quan-Lin Li, Qiang Gao, Jia-Hao Jiang, Xiao-Yong Huang, Jin-Feng Pan, Jia Fan, Jian ZhouFang-Ming Gu, Quan-Lin Li, Qiang Gao, Jia-Hao Jiang, Xiao-Yong Huang, Jin-Feng Pan, Jia Fan, Jian Zhou, Liver Cancer Institute, Zhongshan Hospital and Shanghai Medical School, Fudan University, Shanghai 200032, China Author contributions: Gu FM, Li QL and Gao Q contributed equally to this work Gu FM and Li QL performed the experi- ments and interpretation of the data and statistical analysis Zhou J and Gao Q contributed to the conception and design of the study Gu FM, Gao Q, Li QL and Zhou J wrote the manuscript Jiang JH, Huang XY, Pan JF and Fan J made substantial contri- bution to the design and conception of the study and interpreta- tion of data all authors read and approved the f inal manuscript. 2011World Journal of Gastroenterology2011,17,34:18

5Visualizing the microtubule-associated protein tau in the nucleus显示文摘Although tau is mainly known as an axonal microtubule-associated protein,many studies indicate that it is not restricted to this subcellular compartment.Assessing tau’s subcellular distribution,however,is not trivial as is evident from transgenic mouse studies.When human tau is over-expressed,it can be immunohistochemically localized to axons and the somatodendritic domain,modeling what is found in neurodegenerative diseases such as Alzheimer’s disease.Yet,in wild-type mice,despite its abundance,tau is difficult to visualize even in the axon.It is even more challenging to detect this protein in the nucleus,where tau has been proposed to protect DNA from damage.To establish a framework for future studies into tau’s nuclear functions,we compared several methods to visualize endogenous nuclear tau in cell lines and mouse brain.While depending on the fixation and permeabilization protocol,we were able to detect nuclear tau in SH-SY5Y human neuroblastoma cells,we failed to do so in N2a murine neuroblastoma cells.As a second method we used subcellular fractionation of mouse tissue and found that in the nucleus tau is mainly present in a hypophosphorylated form.When either full-length or truncated human tau was expressed,both accumulated in the cytoplasm,but were also found in the nuclear fraction.Because subcellular fractionation methods have their limitations,we finally isolated nuclei to probe for nuclear tau and found that the nuclei were free of cytoplasmic contamination.Together our analysis identifies several protocols for detecting tau in the nucleus where it is found in a less phosphorylated form.LU Jing LI Ting HE RongQiao BARTLETT Perry F GTZ Jürgen 2014Science China(Life Sciences)2014,57,4:11

10Solving surface plasmon resonances and near field in metallic nanostructures:Green’s matrix method and its applications显示文摘With the development of nanotechnology,many new optical phenomena in nanoscale have been demonstrated.Through the coupling of optical waves and collective oscillations of free electrons in metallic nanostructures,surface plasmon polaritons can be excited accompanying a strong near field enhancement that decays in a subwavelength scale,which have potential applications in the surface-enhanced Raman scattering,biosensor,optical communication,solar cells,and nonlinear optical frequency mixing.In the present article,we review the Green's matrix method for solving the surface plasmon resonances and near field in arbitrarily shaped nanostructures and in binary metallic nanostructures.Using this method,we design the plasmonic nanostructures whose resonances are tunable from the visible to near-infrared,study the interplay of plasmon resonances,and propose a new way to control plasmonic resonances in binary metallic nanostructures.GU Ying LI Jia MARTIN Olivier J F GONG QiHuang 2010Chinese Science Bulletin2010,55,24:3
