Epidemiological surveys show that a large number of cerebrovascular diseases occur in China every year, and among these cerebrovascular diseases, ischemic diseases are predominant. Ischemia leads to irreversible degenerative necrosis of a large number of brain neurons and severe neurological deficits. Aims. This study is aimed at exploring the mechanism of the major regulatory effect of hypoxia-inducible factor 1 (HIF-1) pathway on proangiogenesis and providing new ideas for the treatment of ischemic stroke. Materials and Methods. The rats were randomly divided into normal and ischemic control groups, and the ischemic control group was subjected to the middle cerebral artery occlusion (MCAO) cerebral ischemia model by the wire embolization method, and the rats were executed in batches at 6\u2009h, 1\u2009d, and 3\u2009d after ischemia-reperfusion, and the brain tissue specimens were taken for examination to investigate the effect of hypoxia-inducible factor 1 (HIF-l) signaling pathway on acute ischemic stroke. Results. At 3\u2009d, the number of VEGFR2 positive cells increased significantly, and there was a significant difference compared with the control group (\n \n \n P<\/a:mi>\n <<\/a:mo>\n 0.05<\/a:mn>\n <\/a:math>\n <\/jats:inline-formula>\n ). At 3\u2009d, the number of HIF-1\u03b1-positive cells increased significantly, and there was a significant difference compared with the control group (\n \n \n P<\/c:mi>\n <<\/c:mo>\n 0.05<\/c:mn>\n <\/c:math>\n <\/jats:inline-formula>\n ). The number of Hes1+factor VIII positive cells in the ischemic cortex increased significantly on the 1st and 3rd day, and there was a significant difference compared with the control group (\n \n \n P<\/e:mi>\n <<\/e:mo>\n 0.05<\/e:mn>\n <\/e:math>\n <\/jats:inline-formula>\n ). The expression of Hes1 protein was significantly lower than the normal level after 6\u2009h of ischemia, and the protein expression was significantly increased at 1\u2009d and 3\u2009d after ischemia (\n \n \n P<\/g:mi>\n <<\/g:mo>\n 0.05<\/g:mn>\n <\/g:math>\n <\/jats:inline-formula>\n ). Conclusion. By detecting the expression changes of Hesl+factor VII in the ischemic area, the results show that ischemia and hypoxia activate the HIF-1, making the HIF-l the main regulatory pathway in the process of angiogenesis after ischemia.\n <\/jats:p>","DOI":"10.1155\/2022\/1860925","type":"journal-article","created":{"date-parts":[[2022,10,14]],"date-time":"2022-10-14T20:20:14Z","timestamp":1665778814000},"page":"1-8","source":"Crossref","is-referenced-by-count":2,"title":["Effects of Hypoxia-Inducible Factor 1 (HIF-1) Signaling Pathway on Acute Ischemic Stroke"],"prefix":"10.1155","volume":"2022","author":[{"given":"Guoliang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, People's Hospital of Dongxihu District, Wuhan, Hubei 430040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Tao","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Wuhan Third Hospital, Tongren Hospital of Wuhan University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4969-6761","authenticated-orcid":true,"given":"Hui","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine, Wuhan NO.1 Hospital, 215 Zhongshan Avenue, Qiaokou District, Wuhan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.120.029232"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pharmthera.2020.107695"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/9991001"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.pharmthera.2021.107848"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.120.032810"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.26355\/eurrev_201808_15699"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/549412"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s10803-020-04820-w"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1590\/S1677-5538.IBJU.2020.0054"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1038\/emm.2014.86"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.3892\/ijmm.2011.719"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1111\/aos.14845"},{"issue":"10","key":"13","first-page":"753","article-title":"Effect of berberine on angiogenesis and HIF-1\u03b1\/VEGF signal transduction pathway in rats with cerebral ischemia-reperfusion injury","volume":"28","author":"H.
