While they cannot explain aging as a whole, single cause theories of aging can be useful tools to frame discussion and investigation aimed at better understanding aging and its evolution. The theory presented here is aging viewed through the lens of cancer, two entwined processes. Aging is viewed as largely […]

There is, in general, a growing appreciation of the relevance of previously dismissed mechanisms of damage in the pathology of common age-related disease, such as cardiovascular conditions. The biggest challenge in aging and age-related disease is perhaps less the identification of relevant mechanisms, but rather understanding the relative importance of […]

A new treatment may be on the horizon for people suffering from Crohn’s disease after a McMaster University-led study identified serotonin as a possible trigger of flare-ups. Scientists discovered that increased levels of serotonin hormones prevent gut cells from carrying out autophagy, the routine ‘housework’ of the gut cleaning out […]

Telomerase gene therapies usual deliver telomerase reverse transcriptase (TERT), which might be thought of as the most important part of the full telomerase complex. Most research has focused on the ability of telomerase to lengthen telomeres, and where overexpression of telomerase is seen to extend life span in animal models, […]

That the INDY gene can influence life span was one of the earlier discoveries made once researchers begin to manipulate the life span of short-lived species, spurred by the study of slowed aging via calorie restriction, and searching in earnest for the mechanisms by which metabolism determines the pace of […]
