Core promoter mutations alter PD1 mRNA distribution and nascent transcript dynamics. (A) Representative smFISH images of B-lymphocytes probed with Cy3-labeled PD1 oligonucleotides, derived from either the WT or the indicated PD1 core promoter element mutation. (B) Binned and normalized PD1 mRNA distributions of the WT transgene in B-cells (blue, top panel; gray, remaining panels), and of the core promoter mutant transgenes (red).
