Galzus Research,
Dr. Linda Liau and UCLA have been working for years towards identifying key common biomarkers for not only GBM but other cancers as well when noted as having cross connections. Dr. Bosch’s presentation on proteomics leads me to believe that he has been relentlessly pursuing this. I believe that between Dr. Linda Liau, Dr. Bosch and Roswell Park research they have combined to find some significant clues in the data. Roswell Park has been a significant contributor for years now and it seems that something MHRA and NHS have seen has led to this change in classification for cancer in general.
By the way, I agree as well with your hope that this sign portends real movement by the regulators. Best wishes.
