1Pokemon reduces Bcl-2 expression through NF-κ Bp65:a possible mechanism of hepatocellular carcinoma显示文摘Objective:To investigate the relationship among Pokemon,NF-κB p65 and Bcl-2 in hepatoma cells.Methods:HCC cell HepG2,SMMC7721 and human fetal liver cell line L02 cells were used,and expression of Pokemon,NF-κB p65 and Bcl-2 in three cells were detected by realtime PCR and western blot.Then siRNA of Pokemon was applied to inhibit the expression of Pokemon and NF-κB p65 and apoptotic rate was determined by flow cytometric analysis. Results:Expressions of Pokemon,NF-κB p65 and Bcl-2 in human hepatoma cell HepG2, SMMC7721 expression were significantly higher than those in human embryonic stem cells L02. siRNA of Pokemon inhibited the expression of Pokemon,NF-κB p65 and Bcl-2 in liver cancer cells,and significantly increased apoptosis of liver cells.While siRNA of NF-κB n65 inhibited the expression of NF-κB p65 and Bcl-2,but Pokemon expression in hepatoma cells had no significant change.Conclusions:The proto-oncogene Pokemon can inhibit PI4ARF by specific transcription regulation of cell cycle and can induce tumors.In addition,Pokemon can regulate NF-κB p65 through the expression of apoptosis repressor,and promote the development of liver cancer.It suggests signal network in the liver include the regulation of new non-classical NF-κB regulatory pathway.Xinkai Zhao Qiaoming Ning Xiaoning Sun De'an Tian 2011Asian Pacific Journal of Tropical Medicine2011,4,6:11

3Streptozotocin-induced expression of Ngn3 and Pax4 in neonatal rat pancreatic α-cells显示文摘AIM:To investigate the mechanism behind β-cell regeneration in neonatal rat pancreas treated with streptozotocin (STZ).METHODS:Neonatal Sprague Dawley rats were intraperitoneally injected with 70mg/kg STZ.Body weight,pancreas weight and blood glucose were recorded every two days after the treatment.To identify the expression and location of transcription factors in the rat pancreas,double immunofluorescent staining was performed using antibodies to specific cell markers and transcription factors.RESULTS:Expression of Neurogenin 3 (Ngn3),a marker for endocrine precursor cells,was observed by immunofluorescence in a few β-cells and many α-cells.The expression reached a peak 12 d after treatment.Pax4,a transcription factor that lies downstream of Ngn3 and plays an important role in β-cell differentiation,was also expressed in the α-cells of STZ-treated rats.We did not observe significant changes in Nkx6.1,which is essential for β-cell maturation in the treated rats.CONCLUSION:α-cells dedifferentiated into endocrine precursor cells and acquired the ability to dedifferentiate in the neonatal rat pancreas after STZ treatment.Xiao-Di Liang Yuan-Yuan Guo Ming Sun Ying Ding Ning Wang Li Yuan Wei De 2011World Journal of Gastroenterology2011,17,23:5
4Engineering osteoarthritic cartilage model through differentiating senescent human mesenchymal stem cells for testing disease-modifying drugs显示文摘Significant cellular senescence has been observed in cartilage harvested from patients with osteoarthritis(OA).In this study,we aim to develop a senescence-relevant OA-like cartilage model for developing disease-modifying OA drugs(DMOADs).Spe-cifically,human bone marrow-derived mesenchymal stromal cells(MSCs)were expanded in vitro up to passage 10(P10-MSCs).Following their senescent phenotype formation,P10-MSCs were subjected to pellet culture in chondrogenic medium.Results from qRT-PCR,histology,and immunostaining indicated that cartilage generated from P10-MSCs displayed both senescent and OA-like phenotypes without using other OA-inducing agents,when compared to that from normal passage 4(P4)-MSCs.Interestingly,the same gene expression differences observed between P4-MSCs and P10-MSC-derived cartilage tissues were also observed between the preserved and damaged OA cartilage regions taken from human samples,as demonstrated by RNA sequencing data and other analysis methods.Lastly,the utility of this senescence-initiated OA-like cartilage model in drug development was assessed by testing several potential DMOADs and senolytics.The results suggest that pre-existing cellular senescence can induce the generation of OA-like changes in cartilage.The P4-and P10-MSCs derived cartilage models also represent a novel platform for predicting the efficacy and toxicity of potential DMOADs on both preserved and damaged cartilage in humans.Ning Wang Yuchen He Silvia Liu Meagan J.Makarcyzk Guanghua Lei Alexander Chang Peter G Alexander Tingjun Hao Anne-Marie Padget Nuria de Pedro Tsapekos Menelaos Hang Lin 2022Science China(Life Sciences)2022,65,2:5
5Multielement Analysis of Deep-Sea Sediments by Inductively Coupled Plasma Mass Spectrometry显示文摘Marine sediments were dissolved by HNO3-HF-HClO4 in a sealed container at low pressure; HF was evaporated in an open container and salts were dissolved in HCl by heating, then transferred to 2% HNO3 solution. A total of 45 elements, including Li, Be, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Nb, Mo, Cd, In, Sb, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Tl, Pb, Bi, Th and U, were measured by inductively coupled plasma mass spectrometry (ICP-MS). Condi- tions and sample experiments showed that this procedure defines a good experimental method which has the advantages of clear interference, easy operation and reliable results. The concentrations of the 45 elements could be used for resource exploration, envi- ronmental assessment and academic research.XIA Ning WU Zhaohui GUO Dongfa YAO De 2008Journal of Ocean University of China2008,7,2:4

12Potentiometric detection of polyions based on functionalized magnetic nanopaiticles显示文摘A novel potentiometric detection strategy based on functionalized magnetic nanoparticles has been developed for rapid and sensitive sensing of polyions.Highly dispersed magnetic nanoparticles coated with ion exchanger and plasticizer could promote an in situ cooperative ion-pairing interaction between the ion exchanger and the polyion analyte in sample solution by dramatically reducing the mass-transfer distance.With applying a magnetic field,the nanoparticles can be attached to the surface of ion exchanger free polymeric membrane.The observed potential signals are related to the polyion concentrations.The proposed polymeric membrane electrode exhibits a linear relationship between the greatest potential response slope(dE/dt) and the logarithm of protamine concentration in the range of 0.05-5μg/mL with a lower detection limit of 0.033μg/mL.De An Song Rong Ning Liang Rui Ming Zhang Jia Wang Ding Jun Zhang Wei Qin 2010Chinese Chemical Letters2010,21,11:2

14Multifractal analysis of resting state fMRI series in default mode network: age and gender effects显示文摘Age-related changes of resting state in default mode network(DMN)may provide new clues to the developing mechanism of normal brain as well as early diagnosis and therapy of some neuropsychiatric disorders.The application of multifractal theory to functional magnetic resonance imaging(fMRI)signals has recently raised increasing attention.We aim to explore the multifractal characteristics underlying the resting state functional magnetic resonance imaging(rs-fMRI)series extracted from DMN,and two issues are mainly discussed:(1)whether there exist multifractals in rs-fMRI series;(2)whether it is possible to distinguish between the different ages or genders by means of multifractal characteristics.Results demonstrated the existence of multifractals in rs-fMRI series in DMN.In addition,slight differences between young subjects and middle-aged or elderly subjects can be successfully detected by Dasa,a modified measure we proposed.Furthermore,it is revealed that the rs-fMRI series from young subjects possess smaller averaged scale index and weaker long range correlation,while those from middle-aged or elderly people present increasing averaged scale index andstronger long range correlation.Whereas no significant statistical differences has been found between male and female group.Our results,therefore,highlight the potential usefulness of multifractal analysis in fMRI series of a certain brain region,and provide important insights into healthy aging in DMN.Huangjing Ni Xiaolin Huang Xinbao Ning Chengyu Huo Tiebing Liu De Ben 2014Chinese Science Bulletin2014,59,25:2
