In vivo, male and female C57BL\/6 mice were stimulated in 4 \u00b0C, 3 h per day for 1 week to build the model of cold sress. In vitro, hippocampal neuronal cell line (HT22) cells were incubated with or without mifepristone (RU486) for 1 h, then treated with 400 \u03bcM cortisol (CORT) for 3 h. In vivo, autophagy was measured by western blotting. In vitro, monodansylcadaverine staining, western blotting, flow cytometry, transmission electron microscopy, and immunofluorescence were used to characterize the mechanism of autophagy induced by excess CORT. Autophagy was shown in mouse hippocampus tissues following cold exposure, including mitochondrial damage, autophagy, and 5\u2019 AMP-activated protein kinase (AMPK)\/mammalian target of rapamycin (mTOR) pathway activation after CORT treatment. Autophagy did not rely on the glucocorticoid receptor. In addition, autophagy in male mice was more severe. The study would provide new insight into the mechanisms and the negative effect of the cold stress response, which can inform the development of new strategies to combat the effects of hypothermia.<\/jats:p>","DOI":"10.3390\/ani9090682","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T03:17:57Z","timestamp":1568603877000},"page":"682","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Corticosterone Excess-Mediated Mitochondrial Damage Induces Hippocampal Neuronal Autophagy in Mice Following Cold Exposure"],"prefix":"10.3390","volume":"9","author":[{"given":"Bin","family":"Xu","sequence":"first","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Limin","family":"Lang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shize","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianbin","family":"Yuan","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianfa","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3323-6522","authenticated-orcid":false,"given":"Huanmin","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Lian","sequence":"additional","affiliation":[{"name":"College of Animal Science and Veterinary Medicine, Heilongjiang Bayi Agricultural University, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Singh, S., Nandi, A., Banerjee, O., Bhattacharjee, A., Prasad, S.K., Maji, B.K., Saha, A., and Mukherjee, S.
