| 1 | Caffeic acid 3,4-dihydroxyphenethyl ester prevents colorectal cancer through inhibition of multiple cancer-promoting signal pathways in 1,2-Dimethylhydrazine/dextran sodium sulphate mouse model显示文摘OBJECTIVE:To elucidate the potential feature and mechanism of the caffeic acid 3,4-dihydroxyphenethyl ester(CADPE)molecule,which can prevent colorectal cancer(CRC)in the 1,2-Dimethylhydrazine(DMH)/dextran sodium sulphate(DSS)-induced mouse model.METHODS:Institute of cancer research(ICR)male mice were injected with 20 mg/kg DMH for a week.After that,2%DSS was administered in the drinking water for another 7 d.The CADPE treatment was given to the DMH/DSS induced male mice at three different periods until their sacrifice.Histopathological examination was used for observing the CRC development at colonic mucosa.Immunohistochemistry(IHC),blood cells smearing and crypt damage scoring methods were used for investigating the anti-inflammation feature of CADPE related to CRC.The reversing targets searching method was applied with artificial intelligence(AI),computeraided drug designing(CADD)and Ingenuity Pathway Analysis(IPA)techniques for predicting the potential targets and mechanism of CADPE highly related to CRC.RESULTS:The data indicated that CADPE inhibited CRC tumor development in the colitis-associated DMH/DSS induced mouse model after giving the early treatment.CADPE also impeded the acute inflammation by decreasing the infiltration of neutrophils significantly during the initial stage of CRC development.Finally,our data showed that CADPE prevented CRC by blocking active sites of three pivotal protein targets including epidermal growth factor receptor(EGFR),extracellular signal-regulated kinase(ERK)and mammalian target of rapamycin(m TOR)in two major cancer development pathways.CONCLUSIONS:CADPE effectively prevented CRC at early stage of tumor germination in the DMH/DSS mouse model highly likely due to its anti-acute inflammation characteristic and the ability of blocking EGFR,ERK and m TOR activities in two highly related CRC developing pathways. | JIN Tao ZHOU Qian SHEN Jichen ZHANG Zhizhong LIAN Xiaoyuan | 2024 | Journal of Traditional Chinese Medicine2024，44，1： | 0 |
| 2 | Gametic selection in a doubled haploid population derived from anther culture of indica/japonica hybrid of Oryza Sativa L.显示文摘It is one of the key problems for application of anther culture in hybrid breeding, genetic analysis, and molecular mapping whether the doubled haploid (DH) population derived from anther culture of rice crosses represents a randora array of the microspore population, i.e. whether gametic selection occurs in androgenesis. | CHEN Ying LU Chaofu HE Ping SHEN Lishuang XU Jichen ZHU Lihuang,Inst of Genetics,Academia Sinica,Beijing 100101 XU Yunbi Dept of Agro,Zhejiang Agri Univ,Hangzhou 310029,China | 1998 | Chinese Rice Research Newsletter1998，6，4： | 0 |
| 3 | Spatiotemporal variation and evaluation of agriculture green development: a case study of Hainan Province, China显示文摘The realization of green and sustainable development of agriculture is the common pursuit all over the world. Agriculture green development(AGD)program has been proposed as a sustainable development strategy in China,but insufficient is known about the quantitative evaluation of spatiotemporal variation in AGD at the regional scale. This study aimed to assess spatiotemporal patterns in AGD at the county/city-based regional level. For this purpose, a systematic index evaluation system was developed to assess the performance of socioeconomic, food production and environmental components in a key economic region(Hainan Province) of China. Hainan improved its AGD index(representing the overall performance toward achieving AGD) from 38.8 in 1988 to 40.9 in 2019. The socioeconomic development and agricultural productivity have improved with time;environmental quality declined due to overuse of chemicals from 1988 to 2013, but steadily improved after 2013, indicating positive effects of reducing chemical input. There was a higher AGD index in the coastal vs. central regions and the southern vs. northern regions. Scenarios featuring improved nutrient management or optimized diet structure and reduced waste improved economic benefits and social productivity while concurrently reducing environmental degradation. These results provide new insights for the future development of green and sustainable agriculture and formulation of agricultural policies in Hainan Province of China and even other developing countries that are facing or will soon face similar challenges. | Tianxiang YU Jichen ZHOU Lin MA Fusuo ZHANG Zed RENGEL William JDAVIES Jianbo SHEN | 2024 | Frontiers of Agricultural Science and Engineering2024，11，1： | 0 |
| 4 | The spatial transcriptomic landscape of human gingiva in health and periodontitis显示文摘The gingiva is a key oral barrier that protects oral tissues from various stimuli.A loss of gingival tissue homeostasis causes periodontitis,one of the most prevalent inflammatory diseases in humans.The human gingiva exists as a complex cell network comprising specialized structures.To understand the tissue-specific pathophysiology of the gingiva,we applied a recently developed spatial enhanced resolution omics-sequencing(Stereo-seq)technique to obtain a spatial transcriptome(ST)atlas of the gingiva in healthy individuals and periodontitis patients.By utilizing Stereo-seq,we identified the major cell types present in the gingiva,which included epithelial cells,fibroblasts,endothelial cells,and immune cells,as well as subgroups of epithelial cells and immune cells.We further observed that inflammation-related signalling pathways,such as the JAK-STAT and NF-κB signalling pathways,were significantly upregulated in the endothelial cells of the gingiva of periodontitis patients compared with those of healthy individuals.Additionally,we characterized the spatial distribution of periodontitis risk genes in the gingiva and found that the expression of IFI16 was significantly increased in endothelial cells of inflamed gingiva.In conclusion,our Stereo-seq findings may facilitate the development of innovative therapeutic strategies for periodontitis by mapping periodontitis-relevant genes and pathways and effector cells. | Zongshan Shen Ran Zhang Yunjia Huang Jiayao Chen Mengjun Yu Chunhua Li Yong Zhang Lingling Chen Xin Huang Jichen Yang Zhengmei Lin Songlin Wang Bin Cheng | 2024 | Science China(Life Sciences)2024，67，4： | 0 |
