acity in the Brain of Female G93A Mice, An Animal Model of Amyotrophic Lateral Sclerosis (ALS) was conducted by Rajini Seevaratnam1 supervised by Mazen J. Hamadeh1,2 , and co-authored by Sandeep Raha2 and Mark A. Tarnopolsky2 (1School of Kinesiology and Health Science, York University, Toronto, ON, Canada; 2Department of Pediatrics and Medicine, McMaster University Hamilton, ON, Canada). The researchers will present their findings at the 122nd Annual Meeting of the American Physiological Society (APS; www.the-aps.org/press), which is part of the Experimental Biology 2009 scientific conference. The meeting will be held April 18-22, 2009 in New Orleans.
Fifty-one G93A mice were randomly divided into eight groups: control (6 males, 8 females), coffee (5 males, 7 females), caffeine (5 males, 8 females), chlrogenic acid (5 males, 7 females). The control groups were fed a standard rodent diet and were not given any additional supplements. The intervention groups were provided with coffee, caffeine, and chlorogenic acid extracts, respectively, in amounts found in 5-10 cups of coffee per day, controlled for body weight.
Clinical measures: Food intake, body weight, body condition, ability to move, clinical score, and motor performance were all assessed for the effect of diet and time prior to animal sacrifice.
Molecular measures: Markers of oxidative stress (4-HNE; 3-NY), antioxidant enzyme protein content (MnSOD; CAT; GPx1; GR; GPx1 to GR ratio), and cell death (Bax; Bcl-2) were analyzed using the brains of these mice at age 108 days.
Statistical analysis was conducted for males and females separately.
At the end of the study, the researchers found that:

- Coffee: increased food intake by 21%, decreased markers of oxidative stress by 39-65%, increased markers of antioxidant enzyme protein content by 46-139%, and decreased markers of cell death by 34-36%.
