Activation of the ATF6 (Activating Transcription Factor 6) Signaling Pathway in Neurons Improves Outcome After Cardiac Arrest in Mice.
Shen, Yuntian; Li, Ran; Yu, Shu; Zhao, Qiang; Wang, Zhuoran; Sheng, Huaxin; Yang, Wei (Journal of the American Heart Association, 2021-06-11)Background Ischemia/reperfusion injury impairs proteostasis, and triggers adaptive cellular responses, such as the unfolded protein response (UPR), which functions to restore endoplasmic reticulum homeostasis. After cardiac ... -
Activation of the XBP1s/O-GlcNAcylation Pathway Improves Functional Outcome After Cardiac Arrest and Resuscitation in Young and Aged Mice.
Li, Ran; Shen, Yuntian; Li, Xuan; Lu, Liping; Wang, Zhuoran; Sheng, Huaxin; Hoffmann, Ulrike; ... (8 authors) (Shock (Augusta, Ga.), 2021-11)<h4>Abstract</h4>After cardiac arrest (CA) and resuscitation, the unfolded protein response (UPR) is activated in various organs including the brain. However, the role of the UPR in CA outcome remains largely unknown. One ... -
Aging Is Associated With Impaired Activation of Protein Homeostasis-Related Pathways After Cardiac Arrest in Mice.
Shen, Yuntian; Yan, Baihui; Zhao, Qiang; Wang, Zhuoran; Wu, Jiangbo; Ren, Jiafa; Wang, Wei; ... (13 authors) (Journal of the American Heart Association, 2018-09)Background The mechanisms underlying worse outcome at advanced age after cardiac arrest ( CA ) and resuscitation are not well understood. Because protein homeostasis (proteostasis) is essential for cellular and organismal ... -
Cardiac arrest and resuscitation activates the hypothalamic-pituitary-adrenal axis and results in severe immunosuppression.
Zhao, Qiang; Shen, Yuntian; Li, Ran; Wu, Jiangbo; Lyu, Jingjun; Jiang, Maorong; Lu, Liping; ... (16 authors) (Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism, 2021-05)In patients who are successfully resuscitated after initial cardiac arrest (CA), mortality and morbidity rates are high, due to ischemia/reperfusion injury to the whole body including the nervous and immune systems. How ... -
Increasing O-GlcNAcylation is neuroprotective in young and aged brains after ischemic stroke.
Wang, Zhuoran; Li, Xuan; Spasojevic, Ivan; Lu, Liping; Shen, Yuntian; Qu, Xingguang; Hoffmann, Ulrike; ... (11 authors) (Experimental neurology, 2021-05)Spliced X-box binding protein-1 (XBP1s) together with the hexosamine biosynthetic pathway (HBP) and O-GlcNAcylation forms the XBP1s/HBP/O-GlcNAc axis. Our previous studies have provided evidence that activation of this axis ... -
PERK (Protein Kinase RNA-Like ER Kinase) Branch of the Unfolded Protein Response Confers Neuroprotection in Ischemic Stroke by Suppressing Protein Synthesis.
Wang, Ya-Chao; Li, Xuan; Shen, Yuntian; Lyu, Jingjun; Sheng, Huaxin; Paschen, Wulf; Yang, Wei (Stroke, 2020-05)Background and Purpose- Ischemic stroke impairs endoplasmic reticulum (ER) function, causes ER stress, and activates the unfolded protein response. The unfolded protein response consists of 3 branches controlled by ER stress ... -
Single-cell transcriptomic analysis of the immune cell landscape in the aged mouse brain after ischemic stroke.
Li, Xuan; Lyu, Jingjun; Li, Ran; Jain, Vaibhav; Shen, Yuntian; Del Águila, Ángela; Hoffmann, Ulrike; ... (9 authors) (Journal of neuroinflammation, 2022-04-07)<h4>Background</h4>Ischemic stroke is a medical emergency that primarily affects the elderly. A complex immune response in the post-stroke brain constitutes a key component of stroke pathophysiology. This study aimed to ... -
Small ubiquitin-like modifier 2 (SUMO2) is critical for memory processes in mice.
Yu, Shu; Galeffi, Francesca; Rodriguiz, Ramona M; Wang, Zhuoran; Shen, Yuntian; Lyu, Jingjun; Li, Ran; ... (15 authors) (FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 2020-11)Small ubiquitin-like modifier (SUMO1-3) conjugation (SUMOylation), a posttranslational modification, modulates almost all major cellular processes. Mounting evidence indicates that SUMOylation plays a crucial role in maintaining ... -
Ubc9 overexpression and SUMO1 deficiency blunt inflammation after intestinal ischemia/reperfusion.
Karhausen, Jörn; Bernstock, Joshua D; Johnson, Kory R; Sheng, Huaxin; Ma, Qing; Shen, Yuntian; Yang, Wei; ... (9 authors) (Laboratory investigation; a journal of technical methods and pathology, 2018-06)The intestinal epithelium constitutes a crucial defense to the potentially life-threatening effects of gut microbiota. However, due to a complex underlying vasculature, hypoperfusion and resultant tissue ischemia pose a ...
