that is hard to control for in studies of heme transport pathways.

Hamza first started trying to uncover the secrets of heme transport in 2003. After briefly and unsuccessfully studying the question of heme carrying proteins in traditional bacteria and mice models, Hamza switched to a non-intuitive study subject, one that doesn't make heme, but needs it to survive, that doesn't even have blood, but shares a number of genes with humans - the C. elegans roundworm. C. elegans gets heme by eating bacteria in the soil where it lives. "C. elegans consumes heme and transports it into the intestine.

According to Hamza, C. elegans has had several other benefits for studying heme transport. Hamza's team had control of the amount of heme the worms were eating. With only one valve controlling the heme transport, the scientists knew exactly where heme was entering the worm's intestine, where, as in humans, it is absorbed.

Moreover, C. elegans is transparent, so that under the microscope researchers could see the movement of the heme ingested by a live animal.
