| 3 | Modulating effects of RAMPs on signaling profiles of the glucagon receptor family显示文摘Receptor activity-modulating proteins(RAMPs)are accessory molecules that form complexes with specific G protein-coupled receptors(GPCRs)and modulate their functions.It is established that RAMP interacts with the glucagon receptor family of GPCRs but the underlying mechanism is poorly understood.In this study,we used a bioluminescence resonance energy transfer(BRET)approach to comprehensively investigate such interactions.In conjunction with c AMP accumulation,Gaqactivation andβ-arrestin1/2 recruitment assays,we not only verified the GPCR-RAMP pairs previously reported,but also identified new patterns of GPCR-RAMP interaction.While RAMP1 was able to modify the three signaling events elicited by both glucagon receptor(GCGR)and glucagon-like peptide-1 receptor(GLP-1 R),and RAMP2 mainly affectedβ-arrestin1/2 recruitment by GCGR,GLP-1 R and glucagon-like peptide-2 receptor,RAMP3 showed a widespread negative impact on all the family members except for growth hormone-releasing hormone receptor covering the three pathways.Our results suggest that RAMP modulates both G protein dependent and independent signal transduction among the glucagon receptor family members in a receptor-specific manner.Mapping such interactions provides new insights into the role of RAMP in ligand recognition and receptor activation. | Lijun Shao Yan Chen Shikai Zhang Zhihui Zhang Yongbing Cao Dehua Yang Ming-Wei Wang | 2022 | Acta Pharmaceutica Sinica B2022,12,2: | 2 |

| 6 | Using Methanol as a Formaldehyde Surrogate for Sustainable Synthesis of N-Heterocycles via Manganese-Catalyzed Dehydrogenative Cyclization显示文摘The development of an efficient and sustainable synthetic route for formaldehyde production from renewable feedstock,especially in combination with a subsequent transformation to straightforwardly construct valuable chemicals,is highly desirable.Herein,we report a novel manganese-catalyzed dehydrogenative cyclization of methanol as a formaldehyde surrogate with a variety of dinucleophiles for facile synthesis of N-heterocycles.The in situ generated formaldehyde via catalytic methanol dehydrogenation can be selectively trapped by diverse dinucleophiles to avoid several possible side reactions.The utilty of this transformation is further highlighted by its successful appliation to the synthesis of 13C-labeled N-heterocycles using 13CH_(3)OH as a readily accessible 13C-isotope reagent. | Zhihui Shao Shanshan Yuan Yibiao Li Qiang Liu | 2022 | Chinese Journal of Chemistry2022,40,10: | 1 |

| 9 | Facile preparation and efficient MnxCoy porous nanosheets for the sustainable catalytic process of soot显示文摘The pursuit of high-performance is worth considerable effort in catalysis for energy efficiency and environmental sustainability. To develop redox catalysts with superior performance for soot combustion, a series of Mn_(x)Co_(y) oxides were synthesized using MgO template substitution.This method greatly improves the preparation and catalytic efficiency and is more in line with the current theme of green catalysts and sustainable development. The resulting Mn_(1)Co_(2.3) has a strong activation capability of gaseous oxygen due to a high concentration of Co^(3+) and Mn^(3+). The Mn doping enhanced the intrinsic activity by prompting oxygen vacancy formation and gaseous oxygen adsorption. The nanosheet morphology with abundant mesoporous significantly increased the solid–solid contact efficiency and improved the adsorption capability of gaseous reactants. The novel design of Mn_(1)Co_(2.3)oxide enhanced its catalytic performance through a synergistic effect of Mn doping and the porous nanosheet morphology, showing significant potential for the preparation of high-performance soot combustion catalysts. | Miaomiao Hu Kun Zhou Tingyi Zhao Zheng Li Xianhai Zeng Di Yu Xuehua Yu Mingqin Zhao Zhihui Shao Qixiang Xu Bing Cui | 2024 | Green Energy & Environment2024,9,3: | 0 |

| 11 | Vascular bundle connection between seed stalk and seed coat of Caragana arborescens显示文摘The purpose of this study was to investigate the morphology, transmission route of photosynthetic products in the seed stalk of Caragana arborescens Lam. at various stages after flowering and evaluate the role of the seed stalk in seed maturation using scanning electron microscopy. We found that the mature seed stalk mainly consisted of vessels,sclerenchymatous cells and parenchymatous cells. Elongated cells formed a ring at the junction between the seed stalk and seed, and a large hollow was produced by two layers of sclerenchymatous cells in the interior seed, which functions to sustain seed growth. The opening in the center of the ring was closed during an early stage of seed development, and the opening enlarged as the seed matured.There were two routes for material transport, which started from the seed stalk: one from the seed coat to the embryo,and another directly entering the embryo. Vessels, which are abundant in the seed stalk, are the pathway for absorption of nutrients by the seeds. The vessels were densely packed in the seed stalk, and secondary thickening of the cell wall of the vessels was characterized by net thread thickening, while the secondary thickening of the cell wall of the vessels within the seed was characterized by screw thread thickening. The morphological characteristics of the vessels were adaptive to its functions. | Zhihui Luan Daowei Zhou Diankun Shao | 2018 | Journal of Forestry Research2018,29,1: | 0 |
