| 1 | Three-dimensional bioprinted glioblastoma microenvironments model cellular dependencies and immune interactions显示文摘Brain tumors are dynamic complex ecosystems with multiple cell types.To model the brain tumor microenvironment in a reproducible and scalable system,we developed a rapid three-dimensional(3D)bioprinting method to construct clinically relevant biomimetic tissue models.In recurrent glioblastoma,macrophages/microglia prominently contribute to the tumor mass.To parse the function of macrophages in 3D,we compared the growth of glioblastoma stem cells(GSCs)alone or with astrocytes and neural precursor cells in a hyaluronic acid-rich hydrogel,with or without macrophage.Bioprinted constructs integrating macrophage recapitulate patient-derived transcriptional profiles predictive of patient survival,maintenance of stemness,invasion,and drug resistance.Whole-genome CRISPR screening with bioprinted complex systems identified unique molecular dependencies in GSCs,relative to sphere culture.Multicellular bioprinted models serve as a scalable and physiologic platform to interrogate drug sensitivity,cellular crosstalk,invasion,context-specific functional dependencies,as well as immunologic interactions in a species-matched neural environment. | Min Tang Qi Xie Ryan C.Gimple Zheng Zhong Trevor Tam Jing Tian Reilly L.Kidwell Qiulian Wu Briana C.Prager Zhixin Qiu Aaron Yu Zhe Zhu Pinar Mesci Hui Jing Jacob Schimelman Pengrui Wang Derrick Lee Michael H.Lorenzini Deobrat Dixit Linjie Zhao Shruti B.hargava Tyler E.Miller Xueyi Wan Jing Tang Bingjie Sun Benjamin F.Cravatt Alysson R.Muotri Shaochen Chen Jeremy N.Rich | 2020 | Cell Research2020，30，10： | 6 |

| 3 | Development of a highly-specific ^(18)F-labeled irreversible positron emission tomography tracer for monoacylglycerol lipase mapping显示文摘As a serine hydrolase,monoacylglycerol lipase(MAGL) is principally responsible for the metabolism of 2-arachidonoylglycerol(2-AG) in the central nervous system(CNS),leading to the formation of arachidonic acid(AA).Dysfunction of MAGL has been associated with multiple CNS disorders and symptoms,including neuroinflammation,cognitive impairment,epileptogenesis,nociception and neurodegenerative diseases.Inhibition of MAGL provides a promising therapeutic direction for the treatment of these conditions,and a MAGL positron emission tomography(PET) probe would greatly facilitate preclinical and clinical development of MAGL inhibitors.Herein,we design and synthesize a small library of fluoropyridyl-containing MAGL inhibitor candidates.Pharmacological evaluation of these candidates by activity-based protein profiling identified 14 as a lead compound,which was then radiolabeled with fluorine-18 via a facile SNAr reaction to form 2-[^(18)F]fluoropyridine scaffold.Good blood-brain barrier permeability and high in vivo specific binding was demonstrated for radioligand [^(18)F]14(also named as [^(18)F]MAGL-1902).This work may serve as a roadmap for clinical translation and further design of potent 18F-labeled MAGL PET tracers. | Zhen Chen Wakana Mori Jian Rong Michael A.Schafroth Tuo Shao Richard S.Van Daisuke Ogasawara Tomoteru Yamasaki Atsuto Hiraishi Akiko Hatori Jiahui Chen Yiding Zhang Kuan Hu Masayuki Fujinaga Jiyun Sun Qingzhen Yu Thomas L.Collier Yihan Shao Benjamin F.Cravatt Lee Josephson Ming-Rong Zhang Steven H.Liang | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 0 |
