|Section2= |Section3= }} Cycloastragenol is a molecule isolated from various species in the genus ''Astragalus'' that is purported to have telomerase activation activity. A single ''in vitro'' study on human CD4 and CD8 T cells led to claims that cycloastragenol may activate telomerase, leading to controversial claims for its role in reducing the effects of aging. ==History== Cycloastragenol was studied by Geron Corporation and sold to T.A. Sciences in early 2013 who are developing it as a product named TA-65. Bill Andrews of Sierra Sciences has done testing on the anti-aging aspect of TA-65;〔(Dr. Bill Andrews anti-aging test of TA-65 )〕, as well as Maria Blasco in the journal Aging Cell, finding no increase in murine median or mean lifespan but some physiological anti-aging effects without augmenting cancer incidence. 〔http://onlinelibrary.wiley.com/doi/10.1111/j.1474-9726.2011.00700.x/abstract 〕 In late 2013, dietary supplement company RevGenetics released their conclusions on TA-65 that showed it is the single molecule cycloastragenol used in TA-65.〔(TA-65 Molecule is Cycloastragenol )〕 More recently, on May 15, 2014 RevGenetics released a press release where they provide new information about a public UK government application where TA Sciences state (among other things) that the active ingredient in TA-65 is cycloastragenol.〔(TA-65 is 98% Cycloastragenol )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cycloastragenol」の詳細全文を読む スポンサード リンク
