Researchers have discovered that an enzyme called SIRT3 that is located in mitochondria \u2014 the cell's powerhouse \u2014 may protect mice brains against the kinds of stresses believed to contribute to energy loss. Furthermore, mice that ran on a wheel increased their levels of this protective enzyme.<\/p>\n<p>Researchers used a new animal model to investigate whether they could aid neurons in resisting the energy-depleting stress caused by neurotoxins and other factors. They found the following:<\/p>\n<ul>\n<li>Mice models that did not produce SIRT3 became highly sensitive to stress when exposed to neurotoxins that cause neurodegeneration and epileptic seizures.<\/li>\n<li>Running wheel exercise increased the amount of SIRT3 in neurons of normal mice and protected them against degeneration; in those lacking the enzyme, running failed to protect the neurons.<\/li>\n<li>Neurons could be protected against stress through use of a gene therapy technology to increase levels of SIRT3 in neurons.<\/li>\n<\/ul>\n<p>These findings suggest that bolstering mitochondrial function and stress resistance by increasing SIRT3 levels may offer a promising therapeutic target for protecting against age-related cognitive decline and brain diseases. \u00a0The research team report their findings online Nov. 19 in the journal <em>Cell Metabolism<\/em>.<\/p>\n<p>Source: Johns Hopkins Medicine<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As we age or develop neurodegenerative diseases such as Alzheimer's, [&hellip;]<\/p>\n<a href=\"https:\/\/neurodegenerationresearch.eu\/he\/2015\/12\/animal-study-shows-how-exercise-may-energize-brain-cell-function\/\">View Post<\/a>","protected":false},"author":3,"featured_media":2873,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[22],"tags":[84,288,106,290,180,291,156,289],"class_list":["post-5390","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research-news","tag-alzheimers","tag-alzheimers-disease","tag-brain-research","tag-exercise","tag-neurodegeneration","tag-neurodegenerative-diseases","tag-research","tag-sirt3"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
