1主要人参皂甙的分布和比例及人参产品的质量控制显示文摘采用反相高效液相色谱法,对150多种西洋参、人参及三七的根、叶及其产品进行了分析。以8种主要的人参皂甙Rg,Re,Rf,Rb1,Rc,Rb2,Rg2和Rd作为对照品,来评价人参及其产品的质量,这8种人参皂甙的分布及其比例在对人参及其商品的定性、定量分析方面具有显著的意义。本文首次提出了单体皂甙的含量比率这一有价值的数据在人参品种及不同用药部位鉴定方面的有效性。Ma Yuanchun Luo Mai Lynn Malley Monique Doucet(Celex Laboratories Inc., Atholville Industrial Park, 77 Comeau St.,P.

2The hypoxia-inducible factor-1α activates ectopic production of fibroblast growth factor 23 in tumor-induced osteomalacia显示文摘Tumor-induced osteomalacia(TIO) is a rare paraneoplastic syndrome in which ectopic production of fibroblast growth factor 23(FGF23) by non-malignant mesenchymal tumors causes phosphate wasting and bone fractures. Recent studies have implicated the hypoxia-inducible factor-1α(HIF-1α) in other phosphate wasting disorders caused by elevated FGF23, including X-linked hypophosphatemic rickets and autosomal dominant hypophosphatemia. Here we provide evidence that HIF-1α mediates aberrant FGF23 in TIO by transcriptionally activating its promoter. Immunohistochemical studies in phosphaturic mesenchymal tumors resected from patients with documented TIO showed that HIF-1α and FGF23 were co-localized in spindleshaped cells adjacent to blood vessels. Cultured tumor tissue produced high levels of intact FGF23 and demonstrated increased expression of HIF-1α protein. Transfection of MC3T3-E1 and Saos-2 cells with a HIF-1α expression construct induced the activity of a FGF23 reporter construct. Prior treatment of tumor organ cultures with HIF-1α inhibitors decreased HIF-1α and FGF23 protein accumulation and inhibited HIF-1α-induced luciferase reporter activity in transfected cells. Chromatin immunoprecipitation assays confirmed binding to a HIF-1α consensus sequence within the proximal FGF23 promoter, which was eliminated by treatment with a HIF-1α inhibitor. These results show for the first time that HIF-1α is a direct transcriptional activator of FGF23 and suggest that upregulation of HIF-1α activity in TIO contributes to the aberrant FGF23 production in these patients.Qian Zhang Michele Doucet Ryan E Tomlinson Xiaobin Han L Darryl Quarles Michael T Collins Thomas L Clemens 2016Bone Research2016,4,2:6
3Cloning, expression and localization of a trypsin-like serine protease in the spruce budworm, Choristoneura fumiferana显示文摘像胰岛素的脱毛相关的丝氨酸朊酶 cDNA (CfMRSP ) 从云杉芽虫被克隆, Choristoneura fumiferana。全身的 CfMRSP 互补 DNA (cDNA ) 编码了包含了像胰岛素的丝氨酸朊酶的 43 kDa 蛋白质催化领域,而是没有片断领域。C 终端延期包含了五 cystein 残余,它可以允许蛋白质形成通过更暗淡的一个人内部锁住二硫化物契约并且调整 CfMRSP 的活动。种系发生的树分析证明 CfMRSP 与象丝氨酸朊酶 1 Lonomia obliqua 那样的鳞翅类的相当或相同事物聚类,血淋巴朊酶 20 (HP20 ) ,模式识别丝氨酸朊酶先锋(ProHP14 ) 和 Manduca 祷告的像胰岛素的蛋白质一。CfMRSP 的发展表示的北污点分析显示它的抄本首先在外皮被发现并且测试视距在所有期间被生产,从第 4 中间形态幼虫到蛹,但是增加了抄本总是在每根脱毛以后被发现的 CfMRSP 的层次。蛋白质的高水平被免疫组织化学分析在外皮发现。总的来说这些数据建议 CfMRSP 在 molting 和变形期间在外皮起一个作用。Wen-Ying He Yi-Ping Zheng Lin Tang Si-Chun Zheng Catherine Beliveau Daniel Doucet Michel Cusson Qi-Li Feng 2009Insect Science2009,16,6:3
