Following (the CBC link) is a general background radio interview regarding the progress in immunotherapies (CAR-T) for cancer treatments. Although it is not epigenetic as I understand it, it gives an idea of the magnitude of number of cell threrapy trials (600) in progress, the fact that there is a major research center in Calgary (perhaps some synergy or cross polination with Zenith), the fact that there are 40 to 50 CAR-T type drugs and Canadian scientists are getting good reviews.
