Five pillars summary[edit]
Online encyclopedia As objective as possible ##incomplete
Summary of characteristics of target article[edit]
Our article should be between B and GA article quality ratings.
B[edit]
A B-rated article is suitably referenced, shows reasonable coverage, structured, reasonably well-written, contains illustrations, presented for a relatively general audience. More information on this rating can be found here.
GA[edit]
GA stands for "good article" and is characterized by the following: well-written, verifiable with no original research, broad in its coverage, neutral, stable, and illustrated. A more detailed description can be found here.
Differences between B and GA[edit]
The main difference between the two ratings is stage of development with B-rated articles being just below the complete and GA-rated articles attaining completeness through peer-review and polishing.
Aging and Mitochondria[edit]
There are many links between physiological aging and mitochondrial. One link is found in people with Hutchinson-Gilford progeria who experience symptoms that resemble the normal aging phenotype; the gene responsible for the syndrome, progerin, has been shown to cause mitochondrial dysfunction in human skin fibroblasts and mouse models[1]. Additionally, it has been shown that dietary restriction, a widely-supported method of lifespan extension, attenuates the loss of mitochondrial biogenesis associated with aging[2]. Hutchinson-Gilford progeria express decreased abundances of mitochondria which also suggests reduced mitochondrial biogenesis in that syndrome[1]. More investigation into this association is required because the role of mitochondrial biogenesis may not be causative.
