| 1 | Function of lncRNAs and approaches to lncRNA-protein interactions显示文摘Long non-coding RNAs(lncRNAs),which represent a new frontier in molecular biology,play important roles in regulating gene expression at epigenetic,transcriptional and post-transcriptional levels.More and more lncRNAs have been found to play important roles in normal cell physiological activities,and participate in the development of varieties of tumors and other diseases.Previously,we have only been able to determine the function of lncRNAs through multiple mechanisms,including genetic imprinting,chromatin remodeling,splicing regulation,mRNA decay,and translational regulation.Application of technological advances to research into the function of lncRNAs is extremely important.The major tools for exploring lncRNAs include microarrays,RNA sequencing(RNA-seq),Northern blotting,real-time quantitative reverse transcription-polymerase chain reaction(qRT-PCR),fluorescence in situ hybridization(FISH),RNA interference(RNAi),RNA-binding protein immunoprecipitation(RIP),chromatin isolation by RNA purification(ChIRP),crosslinking-immunopurification(CLIP),and bioinformatic prediction.In this review,we highlight the functions of lncRNAs,and advanced methods to research lncRNA-protein interactions. | ZHU JuanJuan FU HanJiang WU YongGe ZHENG XiaoFei | 2013 | Science China(Life Sciences)2013，56，10： | 54 |
| 2 | Combined remediation of DDT congeners and cadmium in soil by Sphingobacterium sp.D-6 and Sedum alfredii Hance显示文摘Combined pollution of 1,1,1-trichloro-2,2-bis (4-chlorophenyl) ethane (DDT) and cadmium (Cd) in agricultural soils is of great concern because they present serious risk to food security and human health.In order to develop a cost-effective and safe method for the removal of DDTs and Cd in soil,combined remediation of DDTs and Cd in soil by Sphingobacterium sp.D-6 and the hyperaccumulator,Sedum alfredii Hance was investigated.After treatment for 210 days,the degradation half-lives of DDTs in soils treated by strain D-6 decreased by 8.1% to 68.0% compared with those in the controls.The inoculation of strain D-6 into soil decreased the uptake of DDTs by pak choi and S.alfredii.The shoots/roots ratios of S.alfredii for the Cd accumulation ranged from 12.32 to 21.75.The Cd concentration in soil decreased to 65.8%-71.8% for S.alfredii treatment and 14.1%-58.2% for S.alfredii and strain D-6 combined treatment,respectively,compared with that in the control.The population size of the DDTs-degrading strain,Simpson index (1/D) and soil respiratory rate decreased in the early stage of treatment and then gradually increased,ultimately recovering to or exceeding the initial level.The results indicated that synchronous incorporation of strain D-6 and S.alfredii into soil was found to significantly (p 0.05) enhance the degradation of DDTs in soil and the hyperaccumulation of Cd in S.alfredii.It was concluded that strain D-6 and S.alfredii could be used successfully to control DDTs and Cd in contaminated soil. | Hua Fang Wei Zhou Zhengya Cao Feifan Tang Dandan Wang Kailin Liu Xiangwei Wu Xiao'e Yang Yongge Sun Yunlong Yu | 2012 | Journal of Environmental Sciences2012，24，6： | 5 |

| 4 | Detection and indication of 1,3,4-C27-29 triol in the sediment of northern South China Sea显示文摘After the detection of the 1,20,21-C_(29) long-chain triol in some sediments and freshwater pteridophytes, in this study, a new homologous long-chain triol, 1,3,4-C_(27-29), is detected for the first time in the Site4 B core sediment in the northern South China Sea. The hydroxyl location and length of the carbon chain of this newly discovered triol differ from those of 1,20,21-C_(29) triol. The test results of its molecular distribution and individual carbon isotope reveal that 1,3,4-C_(29) triol has a good correlation with n-C_(26-30) even carbon-numbered long-chain fatty alcohols, with R^2(n=68) values of 0.905, 0.929 and 0.903, respectively, and its carbon isotope composition, at –32.3‰±1.9‰, is similar to that of n-C_(26-30), at –29.13‰±0.87‰, –32.98‰±1.28‰, and –32.98‰±1.28‰. 1,3,4-C_(29) triol from the Site4 B core sediment and terrigenous long-chain fatty alcohol(n-C_(26-34)) show highly consistent distribution trends in the entire section; thus, the former could serve as a proxy indicator of the terrigenous input. Considering that the 1,20,21-C_(29) triol in previous research belongs to Azolla, which are fresh water pteridophytes, the 1,3,4-C_(27-29) triol identified in this study might have similar biogenetic derivation. Thus, determination of its biogenic area and growing environment could provide potential organic geochemical evidence supporting the terrigenous input and source in the northern South China Sea. | ZHU XiaoWei MAO ShengYi WU NengYou JIA GuoDong SUN YongGe GUAN HongXiang WU DaiDai | 2016 | Science China Earth Sciences2016，59，6： | 2 |
| 5 | Alcohol compounds in Azolla imbricata and potential source implication for marine sediments显示文摘This study investigated the composition of long-chain alkyl diols,triols,sec-alcohols,hydroxyl acids,and other hydroxylated compounds in Azolla imbricata and compared the organic alcohol components of Azolla filiculoides,Azolla microphylla,and South China Sea(SCS)sediments in order to investigate the possible indication of Azolla being the biological source of diols and triols in SCS sediment.Large amounts of diols,monohydroxy acids,and sec-alcohols with internal hydroxy groups atω20 were detected in the three types of Azolla.Among these,1,ω20-diol andω20-hydroxy acid exhibited strong even-odd predominance distribution,whereasω20-sec-alcohol exhibited strong odd-even predominance distribution.In addition,small amounts of diols,triols,and dihydroxy acids with internal hydroxy groups at 9,10 orω9,ω10 were detected,among which the chain length of C_(29)was predominate.Compounds having similar structures as those in Azolla reflected a similar biosynthetic pathway:ω20-hydroxy acid exhibiting even-odd predominance distribution is decarboxylated toω20-sec-alcohol exhibiting odd-even predominance distribution and converted to 1,ω20-diol with even-odd predominance distribution by acyl reduction;ω9,ω10-hydroxy acid is converted to 1,20,21(1,ω9,ω10)-triol by acyl reduction,and then converted to 9,10-diol by hydrogenation and dehydration.The alcohol components in A imbricata were clearly not the biological source of 1,13/1,14/1,15-C_(28,30,32)diols and 1,3,4-C_(27-29)triols in the SCS sediment.Certain marine diatoms might be the source of 1,14-C_(28,30)diol in inshore sediment,but the biological source of diols and triols in the SCS sediment requires further investigation. | MAO ShengYi ZHU XiaoWei WU NengYou JIA GuoDong SUN YongGe GUAN HongXiang WU DaiDai | 2017 | Science China Earth Sciences2017，60，2： | 1 |

| 7 | Effects of induction heating temperature fields on 321 stainless tubes during the expansion process显示文摘Expansion is an important operation in the hot extrusion production line of seamless steel tubes,which is to produce proper hollow billets for extrusion.The billet goes through induction heating before expanded to acquire a proper temperature.In this study,the effects of three types of inhomogeneous temperature fields on 321 stainless tubes during the expansion process were simulated.The results have indicated that it was an optimum temperature filed for expansion,where the temperature varied linearly along radial direction and the temperature was lower on the inner surface.This temperature field is beneficial to improving the stability of expansion and ensuring dimensional accuracy and increasing the utilization rate of tubular billet material. | JIANG Hong BAI Yunfeng XIE Chaoying FAN Yongge WU Ruiheng | 2011 | Baosteel Technical Research2011，5，4： | 0 |
