Elephants provide clues to cancer resistance

Cancer risk is associated with how often cells divide because each time DNA replicates, potential errors may occur. Unlike most mammals, elephants are remarkably resistant to cancer given their size. In a new study published in Cell Reports, researchers explored genes that evolved more quickly in elephants than other mammals to try to identify genes responsible for this protection. They identified several accelerated gene pathways in elephants that are important for DNA repair […]

Is your pet overweight?

A new study conducted by the Banfield Pet Hospital (Vancouver, Washington) reports that as many as 1 in 3 dogs and cats living in the United States are overweight. The study was based on data collected by Banfield veterinary clinics on 2.5 million dogs and half a million cats over the past year. Obesity in pets was not related to the weight status of their owners. In fact, overweight pets were less prevalent in states whose populations […]

Cancer resistance developing in Tasmanian devils

Tasmanian devils are rather large carnivorous marsupials. By large, I mean the world’s largest. In only 2 decades, the population of Tasmanian devils have declined by about 85%, landing these animals on the endangered species list. The cause: an infectious cancer called devil facial tumor disease (DFTD). As the name implies, this cancer causes facial tumors that grow so large, the victims starve to death in as little as 6 […]

Secret to safer stem cell therapy or cure for cancer?

Researchers trying to find cures for cancer find naked mole rats rather interesting. Not only are these animals long-lived by rodent standards, they are also resistant to the development of cancer. By long-lived, we are talking up to 30 years! A team of researchers from Hokkaido University and Keio University in Japan have now isolated stem cells from the skin of naked mole rats and induced them to revert back to pluripotent stem […]

Recap of 2016 Michigan Physiological Society

The Michigan Physiological Society, a chapter of the American Physiological Society, held their 3rd annual meeting last week. As mentioned in a prior post, the keynote address was given by Comparative Physiologist Dr. Hannah Carey (University of Wisconsin School of Veterinary Medicine). You can read about her research in the prior post. Here are other highlights from the meeting: Seminars: or as I prefer to view them… Kelsy Kusch (Undergraduate Student, […]
