| 1 | A novel hepatitis B virus genotyping system by using restriction fragment length polymorphism patterns of S gene amplicons显示文摘AIM: Traditional hepatitis B virus (HBV) genotyping methods using restriction fragment length polymorphism (RFLP) can reliably identify genotypes A to F. As HBV genotypes G and H have been recently identified, this study was to establish an accurate and simple genotyping method for all eight HBV genotypes (A to H).METHODS: Two hundred and forty HBV small S sequences obtained from GeneBank were analysed for restriction enzyme sites that would be genotype-specific. Restriction patterns following digestion with restriction enzymes BsrⅠ, StyⅠ, DpnⅠ, HpaⅡ, and EaeⅠ, were determined to identify all eight HBV genotypes. Mixed genotype infections were confirmed by cloning and further RFLP analysis.RESULTS: The new genotyping method could identify HBV genotypes A to H. Genotypes B and C could be determined by a single step digestion with BsrI and StyI in parallel. This was particularly useful in the Far East where genotypes B and C are predominant. Serum samples from 187 Chinese HBV carders were analysed with this genotyping system, and the genotype distribution was 1.1% (2), 51.9% (97), 40.6% (76) and 4.8% (9) for genotypes A, B, C, and D, respectively. Mixed genotypes were found in only 3 patients (1.6%). Sequence data analysis confirmed the validity of this new method.CONCLUSION: This HBV genotyping system can identify all eight HBV genotypes. It is accurate and simple, and can be widely used for studies on HBV genotyping. | Guo-BingZeng Shu-JuanWen Zhan-HuiWang LiYan JianSun, Jin-LinHou | 2004 | World Journal of Gastroenterology2004，10，21： | 43 |

| 3 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008，28，5： | 24 |
| 4 | miR-503-3p promotes epithelialemesenchymal transition in breast cancer by directly targeting SMAD2 and E-cadherin显示文摘Although progress in clinical and basic research has significantly increased our understanding of breast cancer, little is known about the molecular mechanism underlying breast cancer metastasis. Identification of effective therapeutic targets to prevent breast cancer metastasis is urgently needed. The function of mi R-503-3p has been investigated in other cancers, but its role in breast cancer remains undefined.Here, we found that mi R-503-3p was overexpressed in breast cancer tissue and plasma compared with adjacent normal breast tissue and with plasma from healthy individuals. Moreover, we identified mi R-503-3p to be an oncogene of breast cancer cell proliferation, migration and invasion. Upregulation of mi R-503-3p in breast cancer cells inhibited expression of epithelialemesenchymal transition(EMT)-related protein SMAD2 and the epithelial marker protein E-cadherin by directly binding to their m RNA30 untranslated region, whereas increased expression of mesenchymal marker proteins, including vimentin and N-cadherin. Taken together, our findings support a critical role for mi R-503-3p in induction of breast cancer EMT and suggest that plasma mi R-503-3p may be a useful diagnostic biomarker for breast cancer. | Zitong Zhao Xinyi Fan Lanfang Jiang Zhongqiu Xu Liyan Xue Qimin Zhan Yongmei Song | 2017 | Journal of Genetics and Genomics2017，44，2： | 15 |
| 5 | Origin and phylogenetic analysis of Tibetan Mastiff based on the mitochondrial DNA sequence显示文摘At present,the Tibetan Mastiff is the oldest and most ferocious dog in the world. However,the origin of the Tibetan Mastiff and its phylogenetic relationship with other large breed dogs such as Saint Bernard are unclear. In this study,the primers were designed accord-ing to the mitochondrial genome sequence of the domestic dog,and the 2,525 bp mitochondrial sequence,containing the whole sequence of Cytochrome b,tRNA-Thr,tRNA-Pro,and control region of the Tibetan Mastiff,was obtained. Using grey wolves and coyotes as out-groups,the Tibetan Mastiff and 12 breeds of domestic dogs were analyzed in phylogenesis. Tibetan Mastiff,domestic dog breeds,and grey wolves were clustered into a group and coyotes were clustered in a group separately. This indicated that the Tibetan Mastiff and the other domestic dogs originated from the grey wolf,and the Tibetan Mastiff belonged to Carnivora,Canidae,Canis,Canis lupus,Canis lupus familiaris on the animal taxonomy. In domestic dogs,the middle and small breed dogs were clustered at first; German Sheepdog,Swedish Elkhound,and Black Russian Terrier were clustered into one group,and the Tibetan Mastiff,Old English Sheepdog,Leonberger,and Saint Bernard were clustered in another group. This confirmed the viewpoint that many of the famous large breed dogs worldwide such as Saint Bernard possibly had the blood lineage of the Tibetan Mastiff,based on the molecular data. According to the substitution rate,we concluded that the approximate divergence time between Tibetan Mastiff and grey wolf was 58,000 years before the present (YBP),and the approximate divergence time between other domestic dogs and grey wolf was 42,000 YBP,demonstrating that the time of origin of the Tibetan Mastiff was earlier than that of the other domestic dogs. | Qifa Li Zhenshan Liu Yinxia Li Xingbo Zhao Liyan Dong Zengxiang Pan Yuanrong Sun Ning Li Yinxue Xu Zhuang Xie | 2008 | Journal of Genetics and Genomics2008，35，6： | 15 |

| 7 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |
| 8 | Experimental investigation on color variation mechanisms of structural light in Papilio maackii ménétriès butterfly wings显示文摘The body color in animals results from billions of years of their natural evolution in order to evade natural enemies, catch quarries or display themselves beauty, in-vestigation on mechanisms of structural light is an important aspect of bionics. Based on the phenomenon of Papilio maackii ménétriès’ blue scales changing into green ones immediately after dropping some alcohol aqua on the underwing sur-face and soon returning back to the original color, the relationship between micro-structure, optics characteristic of scales and changing color effect were studied using the Olympus Stereomicroscope, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Ultraviolet (UV)-Visible Spectropho-tometer. The color variation mechanisms of blue scales of Papilio maackii mé-nétriès in Chinese Northeast were revealed in this paper. When visible lights trav-eled through the concaver structure with multilayer reflector and the filled medium with different refractive indices, the reflected lights in definite wavelengths pro-duced interference and color at that wavelength came into being. It has important academic reference value to biomimetics design of video stealth materials. | REN LuQuan QIU ZhaoMei HAN ZhiWu GUAN HuiYing WU LiYan | 2007 | Science China(Technological Sciences)2007，50，4： | 13 |
| 9 | Application of Pb isotopic tracing technique to constraining the source of Pb in the West Lake Longjing tea显示文摘This paper dealt with the Pb contents and Pb isotopic composition of the West Lake Longjing tea. The results showed that in the tea leaves, from young leaf →old leaf →tea limb, the Pb contents tend to increase gradu-ally from 1.63 →4.84 →6.07×10-6, wich revealed that the Pb was accumulated gradually in the tea. After cleaned, the Pb contents of tea leaves were significantly reduced. This indicated that the deposits on the surface of tea leaves made a great contributuion to Pb contents. The survey results for soils in the relevant tea gardens showed that soil from the Longjing tea garden has higher Pb contents, with an average level of 49.6×10-6, two times those of common soils (24×10-6) in China. Results of the systematic analysis for tea, tea garden soil and the samples with the relevant background of the Pb isotopic composition displayed that the Pb isotopic ratio of tea is 206Pb/207Pb=1.164±0.005 (2σ). The ratio of 206Pb/207Pb for the soil gradually decreased from residue phase, soil dilute acid extract phase, and then to urban topsoil, i.e., 1.175 →1.171 →1.170. The 208Pb/(206Pb+207Pb) ratios also show a similar variation trend. 206Pb/207Pb ratios in the samples with the relevant background were: vehicle exhaust, 1.124; coal-combustion, 1.156; atmosphere, 1.168; and water, 1.166. Comparative studies have shown that Pb pollution is popular in the environ-mental media (soil, atmosphere, water) in Hangzhou. With the aggravation of Pb pollution, the Pb isotopic composi-tion gradually changed from the natural background (soil residues) to the direction of automobile exhaust. This phe-nomenon could illustrate that the pollution source was the vehicle exhaust, while the coal-combustion contributed little to environmental pollution in Hangzhou. The Pb of the Longjing tea came mostly from soluble phase Pb in the polluted soil. Moreover, secondary pollution was caused by vehicle exhaust. | LU Yuanfa YANG Hongmei MA Liyan CHEN Xiqing WANG Qunying | 2011 | Chinese Journal Of Geochemistry2011，30，4： | 13 |
| 10 | A Spore-Pollen Assemblage from the Damoguaihe Formation in the Tamutsag Basin, Mongolia and Its Geological Implication显示文摘Based on the palynological data from Well Ta-19-36 and Well Ta-19-37 in the Ta'nan Sag, and Well Ta-22-1 and Well Ta-21-1 in the Bayin Gobi Sag, a spore-pollen assemblage from the Damoguaihe Formation is named as Cicatricosisporites minutaestriatus- Aequitriradites spinulosus-Protopinus sp. assemblage in the Tamutsag Basin, Mongolia. The assemblage is characterized by abundant gymnosperm pollen and diverse fern spores, counted 46.35%–65.57% and 34.43%–52.58% in percentage respectively. Among the gymnosperm pollen, Pinuspollenites sp.(2.66%–16.94%), Protopinus sp.(0–11.38%) and Protopicea sp.(0–10.81%) are dominant; and Alisporites sp., Cerebropollenites sp., Podocarpidites sp., and Abietineaepollenites sp. are common. Some important elements, such as Chasmatosporites sp., Callialasporites prominulus, Parvisaccites sp., Parcisporites sp., Jiaohepollis cf. annulatus, J. bellus, J. verus, Polycingulatisporites sp., Schizaeoisporites certus, Classopollis annulatus are seen. Within the fern spores, Osmundacidites wellamanii(0.85%–4.93%), Appendicisporites sp.(0–4.45%), Baculatisporites comaumensis(0.80%–2.87%), Cicatricosisporites sp.(0.51%–2.66%), C. minor(0–2.14%), Foraminisporis asymmetricus(0–2.40%), Aequitriradites sp.(0– 2.19%) and Cyathidites minor(0–2.13%) are dominant; and some specie of Densoisporites, Cooksonites, Impardecispora, Pilosisporites, Schizaeosprites, Fixisporites, Leptolepidites, Trilobosporites, Kuylisporites, Klukisporites, Hsuisporites, Couperisporites, Maculatisporites are seen. The angiosperm pollen are rare in the assemblage, characterized by Clavatipollenites sp.(0–0.80%) and Songipollis sp.(0–0.27%). The geological age of the Damoguaihe Formation is assigned to Hauterivian – Barremian of Early Cretaceous according to the palynological data, due to the fact that there existed a lot of diverse spores of the family Schizaeaceae and prosperous gymnosperm saccat pollen which the corpus and sacci are differentiated completely, and the presence of early angiosperm pollen of Clavatipollenites. However, the zircon U-Pb isotopic dating of the volcanic rocks in the Nantun Formation indicated that the overlying strata of the Nantun Formation, i.e. the Damoguaihe Formation must be younger than 127.0±2.0–137.9±1.5 Ma. This is consistent with the palynological data. Furthermore, the vegetation reconstructed on the palynological data of the Damoguaihe Formation is conifer forest with shrubs and grassland, belonging to the semi-humid or humid middle to south subtropical climate. Moreover, three new species, namely Biretisporites punctatus sp. nov., Chasmatosporites reticulates sp. nov. and Concentrisporites contractus sp. nov. are described here. | WANG Liyan WAN Chuanbiao SUN Yuewu | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 12 |
| 11 | RAB31 marks and controls an ESCRT-independent exosome pathway显示文摘Exosomes are generated within the multivesicular endosomes(MVEs)as intraluminal vesicles(ILVs)and secreted during the fusion of MVEs with the cell membrane.The mechanisms of exosome biogenesis remain poorly explored.Here we identify that RAB31 marks and controls an ESCRT-independent exosome pathway.Active RAB31,phosphorylated by epidermal growth factor receptor(EGFR),engages flotillin proteins in lipid raft microdomains to drive EGFR entry into MVEs to form ILVs,which is independent of the ESCRT(endosomal sorting complex required for transport)machinery.Active RAB31 interacts with the SPFH domain and drives ILV formation via the Flotillin domain of flotillin proteins.Meanwhile,RAB31 recruits GTPase-activating protein TBC1D2B to inactivate RAB7,thereby preventing the fusion of MVEs with lysosomes and enabling the secretion of ILVs as exosomes.These findings establish that RAB31 has dual functions in the biogenesis of exosomes:driving ILVs formation and suppressing MVEs degradation,providing an exquisite framework to better understand exosome biogenesis. | Denghui Wei Weixiang Zhan Ying Gao Liyan Huang Run Gong Wen Wang Ruhua Zhang Yuanzhong Wu Song Gao Tiebang Kang | 2021 | Cell Research2021，31，2： | 12 |
| 12 | Estimation of the Effects of Maize Straw Return on Soil Carbon and Nutrients Using Response Surface Methodology显示文摘Straw incorporation is generally considered an effective agricultural management practice that improves nutrient cycling and maintains soil fertility. To study the interactive effects of straw returning factors on soil organic carbon and available nutrients, a17-month(May 6, 2016 to October 6, 2017) experiment was conducted on straw incorporation by using response surface methodology under a three-factor(straw length, amount, and burying depth), five-level quadratic orthogonal rotation experimental design. Weight was assigned to each indicator for soil carbon and nutrients and then a comprehensive indicator was established. Then, a second-order polynomial model of the three straw returning factors was established using response surface methodology. Results indicated that17 months after straw incorporation, straw amount and burying depth had significant effects on the comprehensive indicator of soil carbon and nutrients. Straw length and the interactions of straw amount and burying depth showed no significant effects on the comprehensive indicator of soil carbon and nutrients. It was concluded that 17 months after straw incorporation, the highest value of the comprehensive indicator of soil carbon and nutrients was achieved when the straw length, amount, and burying depth were approximately 17–20 cm, 740–840 g m^(-2), and 9–13 cm, respectively, which can be recommended as the most suitable parameters for use in straw returning in the study area. | ZHOU Dongxing SU Ye NING Yucui RONG Guohua WANG Guangdong LIU Di LIU Liyan | 2018 | Pedosphere2018，28，3： | 12 |
| 13 | Fluorination vs. chlorination: a case study on high performance organic photovoltaic materials显示文摘Halogenation is a very efficient chemical modification method to tune the molecular energy levels, absorption spectra and molecular packing of organic semiconductors. Recently, in the field of organic solar cells(OSCs), both fluorine-and chlorinesubstituted photovoltaic materials, including donors and acceptors, demonstrated their great potentials in achieving high power conversion efficiencies(PCEs), raising a question that how to make a decision between fluorination and chlorination when designing materials. Herein, we systemically studied the impact of fluorination and chlorination on the properties of resulting donors(PBDB-T-2 F and PBDB-T-2 Cl) and acceptors(IT-4 F and IT-4 Cl). The results suggest that all the OSCs based on different donor and acceptor combinations can deliver good PCEs around 13%–14%. Chlorination is more effective than fluorination in downshifting the molecular energy levels and broadening the absorption spectra. The influence of chlorination and fluorination on the crystallinity of the resulting materials is dependent on their introduction positions. As chlorination has the advantage of easy synthesis, it is more attractive in designing low-cost photovoltaic materials and therefore may have more potential in largescale applications. | Yun Zhang Huifeng Yao Shaoqing Zhang Yunpeng Qin Jianqi Zhang Liyan Yang Wanning Li Zhixiang Wei Feng Gao Jianhui Hou | 2018 | Science China Chemistry2018，61，10： | 11 |

| 15 | Spatial and Temporal Changes of Arable Land Driven by Urbanization and Ecological Restoration in China显示文摘Since the industrial revolution, human activities have both expanded and intensified across the globe resulting in accelerated land use change. Land use change driven by China’s development has put pressure on the limited arable land resources, which has affected grain production. Competing land use interests are a potential threat to food security in China. Therefore, studying arable land use changes is critical for ensuring future food security and maintaining the sustainable development of arable land. Based on data from several major sources, we analyzed the spatio-temporal differences of arable land among different agricultural regions in China from 2000 to 2010 and identified the drivers of arable land expansion and loss. The results revealed that arable land decreased by 5.92 million ha or 3.31%. Arable land increased in the north and decreased in the south of China. Urbanization and ecological restoration programs were the main drivers of arable land loss, while the reclamation of other land cover types(e.g., forest, grassland, and wetland) was the primary source of the increased arable land. The majority of arable land expansion occurred in the Northwest, but the centroid for grain production moved to northeast, which indicated that new arable land was of poor quality and did not significantly contribute to the grain production capacity. When combined with the current ‘Red Line of Arable Land Policy’(RAL) and ‘Ecological Redline Policy’(EPR), this study can provide effective information for arable land policymaking and help guide the sustainable development of arable land. | WANG Liyan ANNA Herzberger ZHANG Liyun XIAO Yi WANG Yaqing XIAO Yang LIU Jianguo OUYANG Zhiyun | 2019 | Chinese Geographical Science2019，29，5： | 9 |

| 18 | Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding. | Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang | 2020 | Science China(Life Sciences)2020，63，11： | 8 |
| 19 | TRAP1 Shows Clinical Significance and Promotes Cellular Migration and Invasion through STAT3/MMP2 Pathway in Human Esophageal Squamous Cell Cancer显示文摘Tumor necrosis factor receptor-associated protein 1(TRAP1), an important member of mitochondrial heat shock protein 90 family, is involved in multiple biological processes in several types of tumors. However, its pathological role in esophageal squamous cell cancer(ESCC) remains unknown. Herein, we demonstrated the clinical value of TRAP1, and its role in apoptosis and motility in ESCC. The clinical potential of TRAP1 was investigated through immunohistochemical analysis in 328 ESCC samples, which revealed that strong TRAP1 expression was associated with increased risk of lymph node metastasis, while high TRAP1 expression correlated with poor prognosis. Expression of TRAP1 was found to be an independent prognostic factor for patients with ESCC. Additionally, the upregulation of TRAP1 antagonized cisplatin-induced apoptosis while its downregulation sensitized cells to cisplatin-induced apoptosis. As revealed by the transwell assay, TRAP1 overexpression promoted cellular migration and invasion as compared to the control groups. In contrast,silencing of endogenous TRAP1 expression attenuated the ability of migration and invasion. Finally, the molecular mechanism investigated in the present study demonstrated that TRAP1-mediated migration and invasion occurred through STAT3/MMP2 signaling pathway. In conclusion, TRAP1 may be considered as a molecular predictive marker for prognosis and a novel molecular candidate for therapeutic target in ESCC. | Yunwei Ou Lingyan Liu Liyan Xue Wei Zhou Zitong Zhao Bainan Xu Yongmei Song Qimin Zhan | 2014 | Journal of Genetics and Genomics2014，41，10： | 8 |
| 20 | Purifi cation, characterization and hypoglycemic activity of glycoproteins obtained from pea (Pisum sativum L.)显示文摘This study aimed to isolate and characterize the structures of glycoproteins from peas and determine their hypoglycemic activity.The crude pea glycoproteins(PGP)were extracted by hot water and purified by diethylaminoethyl(DEAE)-Sepharose chromatography and Sephadex G-100 size-exclusion chromatography in sequence.Then three main fractions were obtained,namely PGP1,PGP2 and PGP3,with molecular weights of 897615,846740 and 1194692 Da,respectively.The physical and chemical properties of the three fractions were evaluated and compared by Fourier transform infrared spectroscopy(FT-IR),nuclear magnetic resonance(NMR),scanning electron microscope(SEM),high performance liquid chromatography(HPLC)and other analytical techniques.The fraction PGP2 with the highest hypoglycemic activity,was screened using the Caco-2 monolayer cell model.It can inhibit the uptake of glucose in the small intestine,as well as the activities of maltase and sucrase.After simulated gastrointestinal digestion,PGP2 signifi cantly enhanced the inhibitory effect of α-glucosidase,and slightly reduced the inhibitory ability ofα-amylase.In summary,PGP2 possessed strong hypoglycemic activity after digestion.These results indicated that PGP2 has the potential to be developed into a functional food or natural medicine for the treatment of type 2 diabetes mellitus. | Gaoyixin Qin Wu Xu Junping Liu Liyan Zhao Guitang Chen | 2021 | Food Science and Human Wellness2021，10，3： | 8 |
