Fruit flies live longer on lithium
The benefits of lithium were also seen when it was used as a transient and one-off treatment. Flies that received a one-off dose near the end of their lives lived a maximum of 13% longer and young flies given low doses of lithium chloride for 15 days before switching to a control for the remainder of their lives also lived longer.
"We studied the responses of thousands of flies in different conditions to monitor the effects of lithium and how it extends life. We found low doses not only prolong life but also shield the body from stress and block fat production for flies on a high sugar diet. Low doses also protect against the harmful effects of higher, toxic doses of lithium and other substances such as the pesticide paraquat," said co-author Dr Ivana Bjedov from the UCL Cancer Institute.
