Calorie restriction (CR) extends life span in a wide variety of species. Recent studies suggest that an increase in mitochondrial metabolism mediates CR-induced life span extension. Here we present evidence that Lat1 (dihydrolipoamide acetyltransferase), the E2 component of the mitochondrial pyruvate dehydrogenase complex, is a novel metabolic longevity factor in the CR pathway. Deleting the LA...

the antitumor activity of ethanol extract of prosopis glandulosa torr. (epg) was evaluated against ehrlich ascites carcinoma (eac) tumor model in swiss albino mice on dose dependent manner. the activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. oral administration of epg at the dose of 100, 200 and 400 mg/kg, significantl...
