Poole, Joshua; Jasbi, Paniz; Pascual, Agnes S.; North, Sean; Kwatra, Neha; Weissig, Volkmar; Gu, Haiwei; Bottiglieri, Teodoro; Jadavji, Nafisa M. published the artcile< Ischemic Stroke and Dietary Vitamin B12 Deficiency in Old-Aged Females: Impaired Motor Function, Increased Ischemic Damage Size, and Changed Metabolite Profiles in Brain and Cecum Tissue>, Synthetic Route of 112-63-0, the main research area is human ischemic stroke vitamin B12 deficiency brain cecum metabolite; aging; female; ischemic stroke; motor function; vitamin B12.
A vitamin B12 deficiency (vit. B12 def.) is common in the elderly, because of changes in metabolism Clin. studies have reported that a vit. B12 def. results in worse outcome after stroke, and the mechanisms through which a vit. B12 def. changes the brain requires further investigation. This study investigated the role of vit. B12 def. on stroke outcome and mechanisms using aged female mice. Eighteen-month-old females were put on a control or vit. B12 def. diet for 4 wk, after which an ischemic stroke was induced in the sensorimotor cortex. After damage, motor function was measured, the animals were euthanized, and tissues were collected for anal. Vit. B12 def. animals had increased levels of total homocysteine in plasma and liver, and choline levels were also increased in the liver. Vit. B12 def. animals had larger damage volume in brain tissue and more apoptosis. The cecum tissue pathway anal. showed dysfunction in B12 transport. The anal. of mitochondrial metabolomics in brain tissue showed reduced levels of metabolites involved in the TCA cycle in Vit. B12 def. animals. Motor function after stroke was impaired in vit. B12 def. animals. A dietary Vit. B12 def. impairs motor function through increased apoptosis and changes in mitochondrial metabolism in brain tissue.
