A little sunflower power to brighten up a quiet week…

Understanding Cancer Therapy Resistance: A molecular contribution to resistance to cancer treatments is from the cellular protein Clusterin (CLU).   This cell survival protein is targeted by the antisense based OGX-011, one of OncoGenex Pharmaceutical’s leading compounds currently in phase 2 trials for prostate, lung and breast cancers.  In this recent research project, the mechanism of clusterin mediated treatment resistance was investigated by Dr. Martin Gleave’s team at the University of British Columbia.  They found that CLU enhances the degradation of two proteins, COMMD and I-kappaB, which in turn leads to an increase in the transcriptional activity of NF-kappaB to support cell survival.  These findings surely provide additional potential drug targets for Dr. Gleave, who is the founder of OncoGenex and currently serves as the Chief Scientific Officer.  The study is reported in Molecular Cancer Research.

Sunflower Genome: This is an award announcement to fund the $10.5M (USD) “Genomics of Sunflower” Project.  The contributions are from a ‘cross-border’ consortium including Genome Canada, Genome BC, the US Departments of Energy and Agriculture, and France’s INRA (National Institute for Agricultural Research).  An international team including University of British Columbia researchers and led by Dr. Loren Rieseberg will generate the reference genome that is approximately 3.5 billion bases long for the sunflower family, which includes 24,000 different species.  This agri-biotech project will support the future of the sunflower industry (its seed industry alone is worth $14B) by trying to identify genes that are responsible for agriculturally important traits such as seed-oil content, flowering, seed-dormancy, and wood producing-capacity as well as adapt to today’s changing environment and consumer tastes.
