Members of the astacin family of metalloproteinases such as human bone morphogenetic protein 1 (BMP‐1) have previously been linked to cell differentiation and pattern formation during development through a proposed role in the activation of latent growth factors of the TGF‐β superfamily. Recent finding(1) indicate that BMP‐1 is identical to pro‐collagen C‐proteinase, which is a metalloproteinase involved in extracellular matrix (ECM) formation. This observation suggests that a functional link may exist between astacin metalloproteinases, growth factors and cell differentiation and pattern (...) formation during development. Taken together, current studies indicate that BMP‐1 and possibly other astacin metalloproteinases are multifunctional enzymes that act directly on growth factors and the ECM. In combination, these dual actions would have profound effects on developmental processes. (shrink)

The body wall of Hydra is organized as an epithelial bilayer with an intervening extracellular matrix (ECM). Molecular and biochemical analyses of Hydra ECM have established that it contains components similar to those seen in more complicated vertebrates such as human. In terms of biophysical parameters, Hydra ECM is highly flexible; a property that facilitates continuous movements along the organism's longitudinal and radial axis. A more rigid ECM, as in vertebrates, would not be compatible with this degree of movement. The (...) flexible nature of Hydra ECM can now be explained in part by the unique structure of the organism's collagens. Interestingly, some aspects of the structural features of Hydra collagens mimic what is seen in Ehlers‐Danlos syndrome, an inherited condition in humans that results in an abnormally flexible ECM that can be debilitating in extreme cases. This review will focus on structure–function relationships of the ECM of Hydra. BioEssays 23:716–724, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

While human genetic research promises to deliver a range of health benefits to the population, genetic research that takes place in Indigenous communities has proven controversial. Indigenous peoples have raised concerns, including a lack of benefit to their communities, a diversion of attention and resources from non-genetic causes of health disparities and racism in health care, a reinforcement of “victim-blaming” approaches to health inequalities, and possible misuse of blood and tissue samples. Drawing on the international literature, this article reviews the (...) ethical issues relevant to genetic research in Indigenous populations and considers how some of these have been negotiated in a genomic research project currently under way in a remote Aboriginal community. We consider how the different levels of Indigenous research governance operating in Australia impacted on the research project and discuss whether specific guidelines for the conduct of genetic research in Aboriginal and Torres Strait Islander communities are warranted.
