Upregulation of Autophagy to Treat Age-Related Disease

Regulation of autophagy has been a tremendously popular topic in the aging research community over the past twenty years, so much so that it is very surprising that little progress towards clinical therapies has been made. Search PubMed for autophagy and aging and you'll find a deluge of papers over this time frame, many of which express optimism on the topic of finding ways to upregulate autophagy to improve health and slow the aging process. It is the consensus in the research community that autophagy declines with age, and that there are benefits to be realized through increased autophagy. This may allow many age-related conditions to be treated, slowed, or postponed. All of this is taken as self-evident from the voluminous evidence accumulated to date. What is autophagy? It is a collection of maintenance processes responsible for recycling broken or otherwise unwanted cellular structures and proteins. In the case of chaperone-mediated autophagy, target proteins are guided by a chaperone protein and imported into a lysosome for disassembly. For macroautophagy, an autophagosome membrane forms around the target structure, moves to a lysosome, and fuses with it. In microautophagy, a lysosome directly engulfs the target without assistance. In all cases, a lysosome is the final destination, a membrane packed with enzymes capable of taking apart near everything it will encounter inside a cell. The component parts are then released for reuse. Many of the methods sho...

Authors: Fournier E Abstract Carpal tunnel syndrome (CTS) is too common a condition not to daily interact with the practitioner, if only because of its entanglement to other pathologies, causal or chance association. The typical symptomatology, with hand paresthesia and morning pain upon waking, is related to a median nerve injury in the confined space of the carpal tunnel, more often by local inflammation and tenosynovitis of the finger flexors (repetitive activity of the hands). SCC may be secondary to situations (pregnancy) or conditions (edema, hypothyroidism…), which exaggerate the ordinary pathophysiol...

Publication date: April 2020Source: Colloids and Surfaces B: Biointerfaces, Volume 188Author(s): Didem Cetin, Meltem Okan, Erhan Bat, Haluk KulahAbstractDetection of circulating tumor cells (CTCs) from the bloodstream holds great importance to diagnose cancer at early stages. However, CTCs being extremely rare in blood makes them difficult to reach. In this paper, we introduced different surface modification techniques for the enrichment and detection of MCF-7 in microfluidic biosensor applications using gold surface and EpCAM antibody. Mainly, two different mechanisms were employed to immobilize the antibodies; covalent b...

Dean, Elizabeth Valenti, Karen Hock, Julie Leffler, Amy Compston, William T. AbrahamAbstractBackgroundLower extremity lymphedema is frequently encountered in the vascular clinic. Established dogma purports that cancer is the most common cause of lower extremity lymphedema in Western countries, whereas chronic venous insufficiency (CVI) is often overlooked as a potential cause. Moreover, lymphedema is typically ascribed to a single cause, yet multiple causes can coexist.MethodsA 3-year re...
