8-Oxoguanine transcriptional miscoding can transiently reproduce PAH-associated premature-stop transcripts
Pulmonary arterial hypertension (PAH) is associated with increased oxidative DNA damage, while haploinsufficiency of BMPR2 and other dosage-sensitive genes contributes directly to disease. Template-strand 8-oxoguanine (8-oxoG) provides a potential transient route to the same loss-of-function outcome through transcriptional mutagenesis without altering genomic DNA. RNA polymerase II can insert…
