| 1 | Protective effects of resveratrol on postmenopausal osteoporosis: regulation of SIRT1-NF-κB signaling pathway显示文摘绝经后的骨质疏松症严重地使受危险人的健康。没有副作用,寻找治疗学的药必要性大。我们的学习被设计调查是否 resveratrol, SIRT1 的收缩筋,能在骨质疏松症上并且到有有利效果探索内在的机制。老鼠骨质疏松症模型(卵巢切除术组, OVX ) 被双边的卵巢切除术建立。resveratrol 的三不同剂量被使用:5 mg/kg/d (低剂量,物件 LD ), 25 mg/kg/d (开媒介,物件 MD ), 和 45 mg/kg/d (开高度,物件 HD ) 。结果显示出那物件 LD 没在 OVX 改变上显示出任何重要效果,当时物件 MD 和物件 HD 显著地提高了骨质疏松症导致的减少的骨头矿物质密度(物件 MD 0.205 吗? | Jing Feng Shuai Liu Sai Ma Jian Zhao Wei Zhang Wei Qi Pengchong Cao Zheng Wang Wei Lei | 2014 | Acta Biochimica et Biophysica Sinica2014，46，12： | 70 |
| 2 | LncRNA NKILA suppresses airway hyper reactivity via interfering the facilitation of MUC5AC and MUC5B mediated by GALNT2显示文摘Glycosylation of mucins mediated by N-acetylgalactosaminyltransferases(GALNTs)is closely related to respiratory diseases such as asthma and chronic obstructive pulmonary disease(COPD).In addition,long non-coding RNAs(LncRNAs)participate in physiological and pathological processes through various epigenetic mechanisms.In this study,we found that a novel LncRNA named NKILA combined with multiple mucins and GALNTs potentially by several bioinformatics methods,and we used quantitative real-time PCR(RT-qPCR)to detect the expressions of NKILA,MUC5AC,MUC5B,and GALNT2 mRNA in 50 cases of asthma samples and 19 cases of normal samples,whose results showed that the expression of NKILA was significantly decreased in asthmatic samples,negatively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B,while GALNT2 was significantly increased in asthmatic tissues,and positively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B.In vitro,we used transient transfection technology to overexpress or interfere with NKILA and GALNT2 and then detected the expressions of MUC5AC and MUC5B via RT-qPCR and Western blot,which demonstrated GALNT2 can promote the expressions of MUC5AC and MUC5B protein,while NKILA could inhibit this effect.Furthermore,co-immunoprecipitation results showed that GALNT2 could bind to MUC5AC and MUC5B protein.RNA immunoprecipitation and RNA pull-down experiments showed that NKILA could bind to GALNT2.These evidences suggested that there are correlations among the expression of NKILA,GALNT2,MUC5AC,and MUC5B proteins in asthmatic patients.Mechanically,we concluded that NKILA can suppress the O-linked glycosylation of MUC5AC and MUC5B proteins by binding to GALNT2 and inhibit the expression of MUC5AC and MUC5B proteins.Our researches provided a potential therapeutic target for AHR. | YONGLI ZHANG YIZHAN CAO BO ZHU YANNI JIANG PENGCHONG LIANG | 2021 | BIOCELL2021，45，1： | 1 |
| 3 | Scaffold-like 3D networks fabricated via the organogelation of β-diketone-boron for fluorescent sensing organic amine vapors显示文摘A new compoud based on carbazole functionalized β-diketone-boron difluoride(1) was synthesized.It is found that compoud 1 can gel toluene,ethylbenzene and some mixed solvents,and 3D networks consisting lots of nanofibers were observed using SEM and fluorescence microscopy.The molecular packing model in xerogel 1 was proposed according to the results of XRD,UV/Vis absorption and semiempirical calculations.The obtained nanofibers prepared through organogelation can emit strong orange light under irradiation.It is interesting that the fluorescence of the nanofiber-based film can be quenched quickly and significantly upon exposed to the vapors of n-butylamine,dibutylamine,triethylamine,triethylamine,cyclohexylamine,aniline and pyridine instead of other common reagents.Notably,the response time of the nanofiber-based film to aniline vapor reached ca.0.59 s,and the detection limit for aniline was as low as ca.0.83 mL/m 3. | QIAN Chong CAO KaiYu LIU XingLiang ZHANG XiaoFei XU DeFang XUE PengChong LU Ran | 2012 | Chinese Science Bulletin2012，57，33： | 0 |
