Description

The abstract reports dramatically different IC50 values (402 nM vs 4220 nM) for JQ1 between two medulloblastoma cell lines, but provides no mechanistic explanation. Understanding this differential sensitivity could reveal biomarkers for patient stratification and optimize treatment selection.
