Life, sweet life!

Ontem foi dia de ir ao shopping e, entre outras coisas, tomar um maravilhoso milkshake de Ovomaltine no Bob's; aí, eu venho para casa e me deparo com esta chamada da Cell...
Querem saber de uma coisa?
Vale tudo na luta para esticar a juventude e encurtar a velhice!
Tomem os milshakes que quiserem e não deem ouvidos a estes cientistas imbecis que querem que a gente viva mais para pagar mais o imposto que financia suas pesquisas!
(boa essa teoria, não? Rsrsrsrs)


Longevity: Sweet food, short life

Cell Metab. 10, 379–391 (2009)

Nematode worms fed on a diet spiked with glucose die about 20% earlier than those consuming just the bacterium Escherichia coli.

Cynthia Kenyon and her colleagues at the University of California, San Francisco, found that dietary glucose inhibits the DAF-16 and HSF-1 proteins, which are known to lengthen nematode lifespan. This in turn lowers the activity of the gene aqp-1, which codes for a glycerol channel, suggesting that glucose shortens lifespan by affecting glycerol metabolism.

Worms consuming glycerol also died earlier. The authors think that the worms metabolize glucose into glycerol, which then initiates life-shortening processes.
