Experiments Killing Mice Brings Heat on Angelo State

 

SAN ANGELO, TX – A formal complaint from the Physicians Committee for Responsible Medicine has been filed against Angelo State University for three recent studies that kill and torture mice.

According to the Physicians Committee for Responsible Medicine, on Nov. 3, 2022, the group filed complaints on ASU and the two journals who published the studies. They claimed that the three studies led to unnecessary suffering and death of just under 100 mice.

In the first study, experimenters used mice to study the effects of multiple foster placements on children within the foster care system. Baby mice were removed from their biological mothers 24 hours after birth and then moved again to a new “foster” mother at 11 days old. Researchers tested the mice for “anxiety like” behavior, killed them, and weighed their brains. Researchers concluded that mice who lived in one foster home, as opposed to two, were more “resilient.” Those who lived in several foster homes exhibited the same “resiliency.” Among the 81 mice killed for this study, 15 died from cannibalism and seven died from “neglect or infanticide.”

“If this study model is deemed scientifically valid, it is only fitting that we follow the results to the conclusion that children who are repeatedly moved to new foster homes are far more likely to be eaten by their foster mothers,” the complaint alleged.

According to the Physicians Committee, the studies failed to meet the standards of the Animal Welfare Act (AWA). While the AWA does not protect mice, the statute represents the lowest ethical bar for scientific research.

“If Angelo State’s studies cannot meet even this meager standard,” said the Physicians Committee’s Science Policy Program Manager Janine McCarthy, “the experiments should not have been approved."

"Angelo State cannot justify its use of animals to study the foster care system, a mushroom commonly consumed by humans, or aspects of daily living that could be easily studied using undergraduate students at any campus in the country," McCarthy added.

In the second study, researchers used mice to determine the combined impact of stress and a high-fat diet on cognitive and non-cognitive behaviors in human adolescents. Instead of recruiting humans to study these behaviors using the common stressors and eating habits of adolescents, researchers opted to use mice subjected to water deprivation, bright light/open field exposure, a water-covered cage floor and no bedding, wet bedding, forced swimming, social isolation, predator’s urine, altered light cycle, and a tilted cage.

Ultimately, the author concluded that “the modification of lifestyle factors, including diet and stress during adolescence, serves as a potential strategy to improve cognition in young adulthood.”

The complaint alleges that such an obvious and unrevealing conclusion demonstrates the pointless, wasteful use of animal life in this experiment.

The use of animals in these studies, McCarthy said, disregards the AWA’s mandate that experiments be “designed to assure that discomfort and pain to animals will be limited to that which is unavoidable for the conduct of scientifically valuable research.”

Finally in the third study, a mouse model of Alzheimer’s disease was used to test the anxiety-reducing effects of a commonly consumed mushroom. Seventy-five mice were fed lion’s mane mushroom to determine its effects on cognitive and non-cognitive behaviors for those afflicted with Alzheimer’s disease. The mouse experiment lacked scientific value, the complaint stated, because the mushroom’s cognitive effects have been extensively studied in human subjects. The complaint noted that the experimenters themselves concluded that the mouse model was a limitation of their study. 

The studies were all approved by the Angelo State University Institutional Animal Care and Use Committee (IACUC).
