Scientific studies of a unique Australian frog could lead to the development of new ways to improve livestock production levels and boost the prospects of maintaining human muscle strength into old age.
According to CSIRO Livestock Industries' (CLI) post-doctoral fellow, Dr Nick Hudson, the green-striped burrowing frog (Cyclorana alboguttata) can remain buried in mud for months in an inactive state known as 'aestivation', without any effect on its muscles.
Dr Hudson is part of a collaborative team of researchers, from CLI and the University of Queensland (UQ) who hypothesise that the mechanisms underlying the frog's ability to maintain muscle mass despite starvation, could provide natural and novel ways of optimising muscle production from cattle, sheep, pigs and goats.
"This little animal can remain buried in mud for several months, completely inactive, and yet lose no muscle mass or strength," Dr Hudson says.
"If we can understand how the frog does this, we may be able to target specific genes, or develop new treatments, to enhance muscle mass during the growth of livestock species, or to limit muscle loss during times of nutritional deprivation, such as drought."
Similarly, muscle wasting experienced by astronauts, bed-ridden patients and the elderly, could be addressed.
"A person forced into similar inactivity, would lose in excess of 90 per cent of their muscle strength. This is both a health burden for global populations and a barrier to space exploration," Dr Hudson says.
