| 1 | Rb-Sr and Sm-Nd Isochron Ages of the Dongmozhazhua and Mohailaheng Pb-Zn Ore Deposits in the Yushu area, southern Qinghai and Their Geological Implications显示文摘Located on the northeast margin of the Qiangtang terrane between the Jinshajiang suture zone and Bangonghu-Nujiang suture zone, the Dongmozhazhua and Mohailaheng Pb-Zn deposits in the Yushu area of Qinghai Province are representative Pb-Zn deposits of the Pb-Zn-Cu polymetallic mineralization belt in the northern part of the Nujiang-Lancangjiang-Jinshajiang area, which are in the front belt of the Yushu thrust nappe system. The formed environments of these two deposits are different from those of sediment-hosted base metal deposits elsewhere in the world. The authors hold that they were formed during the Indian-Asian continental collision and developed within the foldthrust belt combined with thrust and strike-slip-related Cenozoic basins in the interior of the collisional zone. Studying on the metallogenic epochs of these two deposits is helpful to the understanding of ore-forming regularity of the regional Pb-Zn-Cu mineralization belt and also to the search for new deposits in this region. The age of the Dongmozhazhua deposit has been determined by the Rb-Sr isochron method for sphalerite residues, whereas the age of the Mohailaheng deposit has been determined by the Rb-Sr isochron method for sphalerite residues and the Sm-Nd isochron method for fluorite. The age of the Dongmozhazhua deposit is 35.0±0.0 Ma((87Sr/86Sr)0=0.708807) for sphalerite residues. The age of the Mohailaheng deposit is 32.2±0.4 Ma((87Sr/86Sr)0=0.708514) for sphalerite residues and 31.8±0.3 Ma((143Nd/144Nd)0=0.512362) for fluorite with an average of 32.0 Ma. Together with the regional geological setting during mineralization, a possible tectonic model for metallogeny of the Dongmozhazhua and Mohailaheng Pb-Zn deposits has been established. These two ages are close to the ages of the Pb-Zn deposits in the Lanping and Tuotuohe basins, indicating that it is possible that the narrow 1000-kilometer-long belt controlled by a thrust nappe system on the eastern and northern margins of the Tibetan plateau could be a giant Pb-Zn mineralized belt. | TIAN Shihong GONG Yingli YANG Zhusen HOU Zengqian LIU Yingchao SONG Yucai XUE Wanwen LU Haifeng WANG Fuchun ZHANG Yubao ZHU Tian YU Changjie | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 8 |

| 4 | Down-regulation of αGal epitopes by co-transfection of α1,3-galactosidase gene and α1,2-fucosyltransferase gene显示文摘The polycarbohydrate structure of Galα1- 3Galβ1-4GluNAc-R (known as αGal epitopes of xenoantigen), produced by α1-3-galactosyltransferase (α1,3-GT) in the course of animal development, is the major xenoantigen on the cell surface of porcine which causes hyperacute rejection in pig-to-human xenotransplantation. Alpha-1,3-galactosi- dase (AGL), a hydrolytic enzyme, can remove the terminal α-1,3-galactosyl from the Galα1-3Galβ1-4GluNAc-R struc-ture resulting in cleaning αGal epitopes from the porcine cells. Alpha-1,2-fucosyltransferase (HT) can modify the sur-face carbohydrate phenotype of porcine cells, bringing about reduction of αGal epitopes expression. In this study, human AGL and HT gene were co-transfected to porcine fetal fibro-blast (PFFb) in equimolar concentration to reduce the xeno-antigen. Gene and protein of hAGL and HT were both de-tected to express at high level by RT-PCR and Western blot, respectively. There was an 84% reduction in αGal xenoanti-gen and an 82% increase in H antigen as assayed by flow cytometry in the AGL and HT gene co-transfected PFFb. The number and morphology of transgenic PFFb chromosome were normal. Findings indicate that Galα1-3Gal epitopes of PFFb could be down regulated by AGL and HT co-transfec- tion without deleterious effects on the chromosomal profile of the transgenic cell. | GONG Feng ZHANG Yangpei JIA Yanjun WANG Yingli TAN Yingxia TIAN shuguang | 2005 | Chinese Science Bulletin2005，50，23： | 0 |
| 5 | Aberrantly Methylated MGMT,hMLH1 and hMSH2 in Tumor and Serum DNA of Gliomas Patients显示文摘OBJECTIVE This study is to investigate the prevalence ofpromoter CpG island methylation of O^6-methylguananine-DNAmethyltransferase (MGMT), mismatch repair genes (hMLH1 andhMSH2) in both tumor and serum samples of gliomas.METHODS Methylation-specific PCR (MSP) was employed todetect promoter CpG island methylation of the MGMT, hMLH1and hMSH2 genes in 39 samples taken from surgery and 32samples of pretreatment serum all from the patients with gliomas.RESULTS Promoter CpG island methylation of MGMT, hMLH1and hMSH2 was detected and the results were 46.2%, 10.3% and20.5%, respectively in tumor DNA of the cases with gliomas,and 40.6%, 9.4% and 18.8%, respectively in serum DNA of thecases. The methylation pattern in primary tumor and serum wasfound to be concordant in matched tissue and serum samplesof 21 patients. In the cases with positive result of methylationfor MGMT, hMLH1 and hMSH2 in tumor tissues, the results ofdetection for those in the paired serum sample were 77.8% (7/9),66.7% (2/3) and 75.0 % (3/4), respectively. False positive resultswere not obtained in any of the patients who did not exhibitmethylation. No association was found between the promotermethylation of MGMT, hMLH1, and hMSH2 genes in primarygliomas and gender, age, localization, grade of malignant or tumorstage.CONCLUSION Promoter CpG island methylation is a frequentevent in gliomagenesis. Methylation analysis appears to bea promising predictive factor of the prognosis for the gliomapatients treated with alkylating drugs and a noninvasive tumormarker in serum DNA. | Changqing Zheng Shouping Ji Feng Gong Anming Li Junli Tai Subuo Li Yingli Wang Hongyu Chang Hongwei Gao Yangpei Zhang | 2009 | Chinese Journal of Clinical Oncology2009，6，1： | 0 |
| 6 | Mechanistic lnsights into the Interactions of Ras Subfamily GTPases withthe SPN Domain of Autism-associated SHANK3显示文摘of main observation and conclusion The active Ras subfamily GTPases,R apl and Ras,can be specifically recognized by the SPN domain of SHANK3,mutations of which are associated with many neuropsychiatric diseases such as autism spectrum disorder(ASD).However,the mechanistic bases underlying the interactions of SHANK3 SPN and those Ras subfamily proteins are still elusive.Here,we reported the crystal structures of SHANK3 SPN in complex with the GTP-bound Raplb and the Ras-mimetic Raplb E30D/K31E double mutant.In addition to uncovering the detailed molecular mechanism governing the specific interactions of SHANK3 SPN with those Ras subfamily proteins,the determined structures also reveal a general binding mode between SHANK3 SPN and its associated Ras subfamily proteins.Finally,our study also provides mechanistic insights into two ASD-causing R12C and L68P mutations found in the SPN domain of SHANK3,and expands our understanding of the etiology of neuropsychiatric diseases caused by defective SHANK3. | Xiaolong Xu Jianping Liu Yingli Wang Yarn Wang Xinyu Gong Lifeng Pan | 2020 | Chinese Journal of Chemistry2020，38，12： | 0 |
