| 1 | The HDAC3 enzymatic activity regulates skeletal muscle fuel metabolism显示文摘Histone deacetylase 3 (HDAC3) is a major HDAC, whose enzymatic activity is targeted by small molecule inhibitors for treating a variety of conditions. However, its enzymatic activity is largely dispensable for its function in embryonic development and hepatic lipid metabolism.HDAC3 plays a pivotal role in regulating muscle fuel metabolism and contractile function. Here, we address whether these muscular functions of HDAC3 require its enzymatic activity. By mutating the NCoR/SMRT corepressors in a knock - in mouse model named NS-DADm, we ablated the enzymatic activity of HDAC3 without affecting its protein levels. Compared to the control mice, skeletal muscles from NS-DADm mice showed lower force generation, enhanced fatigue resistance, enhanced fatty acid oxidation, reduced glucose uptake during exercise, upregulated expression of metabolic genes involved in branchedchain amino acids catabolism, and reduced muscle mass during aging, without changes in the muscle fiber-type composition or mitochondrial protein content. These muscular phenotypes are similar to those observed in the HDAC3-depleted skeletal muscles, which demonstrates that, unlike that in the liver or embryonic development, the metabolic function of HDAC3 in skeletal muscles requires its enzymatic activity. These results suggest that drugs specifically targeting HDAC3 enzyme activity could be developed and tested to modulate muscle energy metabolism and exercise performance. | Shiyan Song Yefei Wen Hui Tong Emanuele Loro Yingyun Gong Jidong Liu Sungguan Hong Lei Li Tejvir S.Khurana Maoping Chu Zheng Sun | 2019 | Journal of Molecular Cell Biology2019，11，2： | 3 |
| 2 | Targeted delivery of a STING agonist to brain tumors using bioengineered protein nanoparticles for enhanced immunotherapy显示文摘Immunotherapy is emerging as a powerful tool for combating many human diseases.However,the application of this life-saving treatment in serious brain diseases,including glioma,is greatly restricted.The major obstacle is the lack of effective technologies for transporting therapeutic agents across the blood-brain barrier(BBB)and achieving targeted delivery to specific cells once across the BBB.Ferritin,an iron storage protein,traverses the BBB via receptor-mediated transcytosis by binding to transferrin receptor 1(TfR1)overexpressed on BBB endothelial cells.Here,we developed bioengineered ferritin nanoparticles as drug delivery carriers that enable the targeted delivery of a small-molecule immunomodulator to achieve enhanced immunotherapeutic efficacy in an orthotopic glioma-bearing mouse model.We fused different glioma-targeting moieties on self-assembled ferritin nanoparticles via genetic engineering,and RGE fusion protein nanoparticles(RGE-HFn NPs)were identified as the best candidate.Furthermore,RGE-HFn NPs encapsulating a stimulator of interferon genes(STING)agonist(SR717@RGE-HFn NPs)maintained stable self-assembled structure and targeting properties even after traversing the BBB.In the glioma-bearing mouse model,SR717@RGE-HFn NPs elicited a potent local innate immune response in the tumor microenvironment,resulting in significant tumor growth inhibition and prolonged survival.Overall,this biomimetic brain delivery platform offers new opportunities to overcome the BBB and provides a promising approach for brain drug delivery and immunotherapy in patients with glioma. | Bin Wang Maoping Tang Ziwei Yuan Zhongyu Li Bin Hu Xin Bai Jinxian Chu Xiaoyang Xu Xue-Qing Zhang | 2022 | Bioactive Materials2022，7，10： | 2 |
