Glial cells under physiologic and pathologic conditions.
Glial cells have long been considered to play roles in the nervous system that are unexciting compared with those of neurons. They provide neurons with nutrients, guide migrating neurons and their precursors during development, and dispose of the brain's "waste." Recent evidence, however, suggests that glial cells play more sophisticated, neuronlike roles. They integrate neuronal input, modulat...
متن کاملAnorexia, sarcopenia, and aging.
Food intake declines throughout the life span. This physiologic anorexia of aging is caused in part by alterations of stomach-fundus compliance and release and activity of cholecystokinin. In addition, the decline in testosterone in males results in elevated leptin levels that increase the anorexia. There is also evidence that cytokines play a role in the pathogenesis of anorexia and sarcopenia...
متن کاملThe anorexia of aging.
Malnutrition in the elderly is one of the greatest threats to health, well-being and autonomy, it is therefore crucial to understand and to contrast the causal factors of inadequate energy intake. This review focuses on the mechanisms of the so-called 'anorexia of aging'. In recent years, it has been shown that elderly subjects have abnormal peripheral signal patterns and alterations in central...
متن کاملApplications of MAGE in Studying Physiologic and Pathologic Mechanisms
A DNA microarray is an orderly arrangement of DNA on solid support, providing a medium for matching known and unknown DNA samples [1]. The types of DNA microarrays and relevant methodologies are reviewed by Chao et al [2]. In this article, we briefly review the current advances in microarray analysis of gene expression (MAGE), focusing on recent reports of the MicroArray Quality Control (MAQC) ...
متن کاملInvolvement of oxygen-sensing pathways in physiologic and pathologic erythropoiesis.
Red blood cells deliver O(2) from the lungs to every cell in the human body. Reduced tissue oxygenation triggers increased production of erythropoietin by hypoxia-inducible factor 1 (HIF-1), which is a transcriptional activator composed of an O(2)-regulated alpha subunit and a constitutively expressed beta subunit. Hydroxylation of HIF-1alpha or HIF-2alpha by the asparaginyl hydroxylase FIH-1 b...
