1Endothelial cells-targeted soluble human Delta-like 4 suppresses both physiological and pathological ocular angiogenesis显示文摘Due to its essential roles in angiogenesis, Notch pathway has emerged as an attractive target for the treatment of pathologic angiogenesis. Although both activation and blockage of Notch signal can impede angiogenesis, activation of Notch signal may be more promising because it was shown that long-term Notch signal blockage resulted in vessel neoplasm. However, an in vivo deliverable Notch ligand with highly efficient Notch-activating capacity has not been developed. Among all the Notch ligands, Delta-like4(Dll4) is specifically involved in angiogenesis. In this study, we generated a novel soluble Notch ligand h D4 R, which consists of the Delta-Serrate-Lag-2 fragment of human Dll4 and an arginine-glycine-aspartate(RGD) motif targeting endothelial cells(ECs). We demonstrated that h D4 R could bind to ECs through its RGD motif and effectively triggered Notch signaling in ECs. Further, we confirmed that h D4 R could suppress angiogenesis in vitro as manifested by network formation assay and sprouting assay. More importantly, h D4 R efficiently repressed neonatal retinal angiogenesis and laser-induced choroidal neovascularization(CNV) as well in vivo. In conclusion, we have developed an in vivo deliverable Notch ligand h D4 R, which suppresses angiogenesis both in vitro and in vivo, thus providing a new approach to tackle excessive angiogenesis relevant disease such as CNV.YAN XianChun YANG ZiYan CHEN Yan LI Na WANG Li DOU GuoRui LIU Yuan DUAN JuanLi FENG Lei DENG SanMing HAN Hua ZHANG Ping 2015Science China(Life Sciences)2015,58,5:5
2Fabrication and electrical characteristics of flash-sintered SiO_(2)-doped ZnO-Bi_(2)O_(3)-MnO_(2) varistors显示文摘The dense ZnO-Bi_(2)O_(3)-MnO_(2)(ZBMS)varistors for x=0,1,2,3 wt% were fabricated by flash sintering method under the low temperature of 850℃ within 2 min.The sample temperature was estimated by a black body radiation model in the flash sintering process.The crystalline phase assemblage,density,microstructure,and electrical characteristics of the flash-sintered ZBMS varistors with different SiO_(2)-doped content were investigated.According to the XRD analysis,many secondary phases were detected due to the SiO_(2) doping.Meanwhile,the average grain size decrease with increasing SiO_(2)-doped content.The improved nonlinear characteristics were obtained in SiO_(2)-doped samples,which can be attributed to the ion migration and oxygen absorption induced by the doped SiO_(2).The flash-sintered ZBMS varistor ceramics for x=2 wt% exhibited excellent comprehensive electrical properties,with the nonlinear coefficient of 24.5,the threshold voltage and leakage current of 385 V·mm^(-1 )and 11.8μA,respectively.Pai PENG Yujun DENG Jingpeng NIU Liyi SHI Yunzhu MEI Sanming DU Juan LIU Dong XU 2020Journal of Advanced Ceramics2020,9,6:3
3A hybrid genipin-crosslinked dual-sensitive hydrogel/nanostructured lipid carrier ocular drug delivery platform显示文摘The objective of this study was to develop a novel hybrid genipin-crosslinked dual-sensitive hydrogel/nanostructured lipid carrier(NLC) drug delivery platform. An ophthalmic antiinflammatory drug, baicalin(BN) was chosen as the model drug. BN –NLC was prepared using melt-emulsification combined with ultra-sonication technique. Additionally, a dual pH-and thermo-sensitive hydrogel composed of carboxymethyl chitosan(CMCS) and poloxamer 407(F127) was fabricated by a cross-linking reaction with a nontoxic crosslinker genipin(GP). GP-CMCS/F127 hydrogel was characterized by FTIR, NMR, XRD and SEM. The swelling studies showed GP-CMCS/F127 hydrogel was both pH-and thermo-sensitive. The results of in vitro release suggested BN –NLC gel can prolong the release of baicalin comparing with BN eye drops and BN –NLC. Ex vivo cornea permeation study was evaluated using Franz diffusion cells. The apparent permeability coefficient(Papp) of BN –NLC gel was much higher(4.46-fold) than that of BN eye drops. Through the determination of corneal hydration levels, BN –NLC gel was confirmed that had no significant irritation to cornea. Ex vivo precorneal retention experiments were carried out by a flow-through approach. The results indicated that the NLC-based hydrogel can prolong precorneal residence time. In conclusion, the hybrid NLCbased hydrogel has a promising potential for application in ocular drug delivery.Yibin Yu Ruoxi Feng Jinyu Li Yuanyuan Wang Yiming Song Guoxin Tan Dandan Liu Wei Liu Xinggang Yang Hao Pan Sanming Li 2019Asian Journal of Pharmaceutical Sciences2019,14,4:3
4Influence of hydroxypropyl methylcellulose,methylcellulose, gelatin, poloxamer 407 and poloxamer 188 on the formation and stability of soybean oil-in-water emulsions显示文摘Macromolecules of polysaccharides, proteins and poloxamers have a hydrophobic portion and a hydrophilic one that can be used as emulsifiers. Parts of these emulsifiers are safe pharmaceutical excipients, which can replace the irritant low molecular weight surfactants to formulate emulsions for the pharmaceutical field. This project focused on preparing O/W emulsions stabilized with polymers for pharmaceuticals such as polysaccharides, proteins and poloxamers, including hydroxypropyl methylcellulose (HPMC), methylcellulose (MC),gelatin, poloxamer 407 (F127) and poloxamer 188 (F68). Emulsion physical stability was assessed by centrifugation, autoclaving sterilization and droplet size measurements. The stabilization mechanisms of emulsions were determined by interfacial tension and rheological measurements. Results stated that the efficacy of these polymers for pharmaceuticals stabilized emulsions was sorted in the order: F127 > F68 > HPMC > MC > Gelatin.Miao Zhang Baixue Yang Wei Liu Sanming Li 2017Asian Journal of Pharmaceutical Sciences2017,12,6:2
5Current sustained delivery strategies for the design of local neurotrophic factors in treatment of neurological disorders显示文摘Although therapeutic potential of neurotrophic factors(NTFs)has been well recognized for over two decades,attempts to translate that potential to the clinic have been disappointing,largely due to significant obstacles in delivery,including inadequate protein dose/kinetics released at target sites.Considerable efforts have been made to improve the therapeutic performance of NTFs.This articles reviews recent developments in localized delivery systems of NTFs for the neurological disorders treatments with a main focus on sustained delivery strategies.Different non-covalent binding approaches have been employed to immobilize proteins in hydrogels,microspheres,electrospun nanofibers,and their combined systems,which serve as depots for sustained local release of NTFs.The challenges associated with current NTFs delivery systems and how these systems can be applied to neurological diseases and disorders have been discussed in the review.In conclusion,optimal delivery systems for NTFs will be needed for reliable and meaningful clinical benefits;ideally,delivering a time and dose-controlled release of bioactive multiNTFs at different individual optimal kinetics to achieve multi-functions in target tissues is significant preferred.Hongzhuo Liu Yanyan Zhou Shichao Chen Meng Bu Jiayu Xin Sanming Li 2013Asian Journal of Pharmaceutical Sciences2013,8,5:2
6SbMYB3 transcription factor promotes root-specific f lavone biosynthesis in Scutellaria baicalensis显示文摘Scutellaria baicalensis Georgi produces abundant root-specific f lavones(RSFs),which provide various benefits to human health.We have elucidated the complete biosynthetic pathways of baicalein and wogonin.However,the transcriptional regulation of f lavone biosynthesis in S.baicalensis remains unclear.We show that the SbMYB3 transcription factor functions as a transcriptional activator involved in the biosynthesis of RSFs in S.baicalensis.Yeast one-hybrid and transcriptional activation assays showed that SbMYB3 binds to the promoter of flavone synthase II-2(SbFNSII-2)and enhances its transcription.In S.baicalensis hairy roots,RNAi of SbMYB3 reduced the accumulation of baicalin and wogonoside,and SbMYB3 knockout decreased the biosynthesis of baicalein,baicalin,wogonin,and wogonoside,whereas SbMYB3 overexpression enhanced the contents of baicalein,baicalin,wogonin,and wogonoside.Transcript profiling by qRT–PCR demonstrated that SbMYB3 activates SbFNSII-2 expression directly,thus leading to more abundant accumulation of RSFs.This study provides a potential target for metabolic engineering of RSFs.Yumin Fang Jie Liu Minmin Zheng Sanming Zhu Tianlin Pei Mengying Cui Lijing Chang Hanwen Xiao Jun Yang Cathie Martin Qing Zhao 2023Horticulture Research2023,10,2:2

12Gap-free genome assembly and CYP450 gene family analysis reveal the biosynthesis of anthocyanins in Scutellaria baicalensis显示文摘Scutellaria baicalensis Georgi,a member of the Lamiaceae family,is a widely utilized medicinal plant.The flavones extracted from S.baicalensis contribute to numerous health benefits,including anti-inflammatory,antiviral,and anti-tumor activities.However,the incomplete genome assembly hinders biological studies on S.baicalensis.This study presents the first telomere-to-telomere(T2T)gap-free genome assembly of S.baicalensis through the integration of Pacbio HiFi,Nanopore ultra-long and Hi-C technologies.A total of 384.59 Mb of genome size with a contig N50 of 42.44 Mb was obtained,and all sequences were anchored into nine pseudochromosomes without any gap or mismatch.In addition,we analysed the major cyanidin-and delphinidin-based anthocyanins involved in the determination of blue-purple flower using a widely-targeted metabolome approach.Based on the genome-wide identification of Cytochrome P450(CYP450)gene family,three genes(SbFBH1,2,and 5)encoding flavonoid 3′-hydroxylases(F3′Hs)and one gene(SbFBH7)encoding flavonoid 3′5′-hydroxylase(F3′5′H)were found to hydroxylate the B-ring of flavonoids.Our studies enrich the genomic information available for the Lamiaceae family and provide a toolkit for discovering CYP450 genes involved in the flavonoid decoration.Tianlin Pei Sanming Zhu Weizhi Liao Yumin Fang Jie Liu Yu Kong Mengxiao Yan Mengying Cui Qing Zhao 2023Horticulture Research2023,10,12:0
