The study on blind mole rat (Spalax) was carried out by researchers from the University of Haifa, Israel, and published in the peer-reviewed scientific journal BMC Biology.

The blind mole rat (Spalax) is an intriguing creature worthy of study. This was animal research examining the resistance subterranean blind mole rats (Spalax) have to cancers. Blind mole rats are one of a unique group of animals that spend their lives underground, are tolerant of very low oxygen levels (down to only 3% concentration – levels that would kill a human), have a long lifespan of more than 20 years, which is exceptional for a small rodent, and show no clear signs of ageing or age-related diseases.

This research has demonstrated the unique abilities of the blind mole rat to resist cancer, even when directly given potent cancer-causing chemicals. In this study researchers gave blind mole rats potent cancer-causing chemicals either through injections or applied directly to the skin, but the animals didn't develop cancer.

Remarkably, connective tissue cells (fibroblasts) taken from the blind mole rat even prevented the growth of human cancer cells when they were grown together in the laboratory.

In the laboratory, the researchers also demonstrated how connective tissue cells called fibroblasts taken from the animal seem to play an important role in this cancer resistance. These cells prevented the growth of human cancer cells when the two types of cells were grown together in the laboratory.

The researchers concluded that, "This report provides pioneering evidence that Spalax [the blind mole rat] is not only resistant to spontaneous cancer, but also to experimentally induced cancer, and shows the unique ability of Spalax fibroblasts to inhibit growth and kill cancer cells, but not normal cells, either through direct fibroblast-cancer cell interaction or via soluble factors."

Nonetheless, there remains optimism that understanding the anti-cancer mechanisms of mole rats may one day help inform further cancer treatments for humans, but a lot more research – and probably a significant amount of time – is needed before this can be considered.
