A new study published in the journal Science Translational Medicine is very illuminating in this respect. The authors identified that KDM6A is mutated at a rate of 36% in non-muscle-invasive and 24% of muscle-invasive bladder cancer. Having established that KDM6A mutations are highly prevalent in bladder cancers, the investigators then proceeded to define the functional role of KDM6A loss. They created a KDM6A knockout clones in RT-4, a wild-type KDM6A bladder carcinoma cell line and observed that KDM6A inactivation results in faster proliferation of these cancer cells.
