| 1 | Chronic intermittent hypoxia accelerates liver fibrosis in rats with combined hypoxia and nonalcoholic steatohepatitis via angiogenesis rather than endoplasmic reticulum stress显示文摘In the present study,we aimed to investigate the role of endoplasmic reticulum stress(ERS)and its related inflammation and angiogenesis in liver fibrosis in a rat model of combined hypoxia and nonalcoholic steatohepatitis(NASH)and to confirm whether the intervention of hypoxia-inducible factor 1α(HIF1α)can improve fibrosis.Liver histological changes and biochemical indices,HIF1α,inflammatory factors,ERS-related parameters(GRP78,CHOP,caspase-3,and caspase-12),and angiogenesis indices(VEGFA,VEGFR2,and CD34)were evaluated.Compared with the control rats,the liver tissue of rats with hypoxia and NASH had obvious NASH characteristics and hepatic fibrosis was significantly aggravated,including bridging fibrosis in some rats.The mRNA expression levels of HIF1α,VEGFA,and VEGFR2 and total immunohistochemical staining scores of VEGFR2 and CD34 were significantly increased.In addition,HIF1α silencing significantly decreased HIF1α,biochemical indices(ALT,AST,and TG),inflammatory factors(TNFα,IL6,and IL1β),and angiogenesis indices(CD34 and VEGFR2),consequently,improved the hepatic fibrosis score in the rat model of combined hypoxia and NASH.Taken together,chronic intermittent hypoxia accelerates liver fibrosis in rats with combined hypoxia and NASH via angiogenesis rather than ERS and HIF1α intervention can improve liver fibrosis,angiogenesis,inflammatory factors,and biochemical indices.Therefore,HIF1α is a key regulatory factor of liver fibrosis in rats with combined hypoxia and NASH. | Wei Wu Weiping Li Jiaojiao Wei Chunsheng Wang Yunliang Yao Weihua Zhu Weimei He Weimei Zhou Jiang Liu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，2： | 8 |
| 3 | Transcriptomic analysis identifies the S100 calcium-binding protein β subunit(S100B)and intercellular adhesion molecule-1(ICAM-1)as potential diagnostic biomarkers for acute cerebral infarction显示文摘Due to its high mortality,disability,and recurrence rates,cerebral infarction has a serious impact on the economy and is a physical and psychological burden on patients.1 There is a huge unmet medical need for biomarkers to predict acute cerebral infarction.Studies have shown that the ischemic damage to neurons,myelin,and glia caused by a stroke leads to the release of the S100 calcium-binding protein beta subunit(S100B)through the blood-brain barrier into the systemic circulation,resulting in an increase in the level of S100B in the peripheral blood. | Dan Cheng Yushuo Wang Jingna Li Yulan Yao Simiao Zhang Yunliang Wang | 2024 | Genes & Diseases2024，11，1： | 0 |
