including up to 300,000 different types of worms that parasitize vertebrates alone. Metazoan parasites are as diverse as they are abundant. They span 15 phyla, ranging from microscopic ...

The epigenetic mark of DNA methylation, once thought to be rare if not nonexistent in worms and flies, occurs throughout the genomes of these organisms and in algae on the base adenine, not the ...

Since then, hundreds of microRNAs have been identified in almost all metazoan genomes, including worms, flies, plants and mammals. MicroRNAs have diverse expression patterns and might regulate ...

Proceedings of the Academy of Natural Sciences of Philadelphia, Vol. 65, No. 1 (Jan. - Mar., 1913), pp. 126-151 (27 pages) ...

For the first time, they have identified the oncogene myc in a fresh water polyp and they have shown that this oncogene has similar biochemical functions in ancestral metazoan and in humans.

But researchers had not found a multi-cellular or metazoan animal that did so until now — the giant tube worms that live by hydrothermal vents, for instance, rely on dissolved oxygen.
