Kermode says the success of the work underscores the power of multidisciplinary research that included contributions from SFU chemistry professor David Vocadlo, and from UBC Medical Genetics professor Lorne Clarke. It further underscores the importance of connections between SFU and Australia's Griffith University, through collaborative researchers Mark von Itzstein and Thomas Haselhorst.

"In 2005, we had the basis of our story worked out," says Kermode. "Taking it to the next level involved their precise analyses to determine the sugar residues on the therapeutic enzyme produced by the modified maize seeds.

"When we first looked at the sugar analysis data we were amazed at how well the 'mRNA-trafficking strategy' had worked, and the high fidelity of the process for controlling the sugar-processing of the therapeutic protein. This is critical as sugar processing influences the characteristics of a protein (enzyme) therapeutic, including its safety, quality, half-life in the bloodstream, and efficacy. The work could well extend to forming a platform for the production of other protein therapeutics."

Kermode also credits SFU research associate Xu He, the first author of the Nature Communications paper. Her funding sources included NSERC Strategic grants and a Michael Smith Foundation for Health Research Senior Scholar Award, and in related research, a Canadian Society for Mucopolysaccharide and Related Diseases grant.
