Pulmonary hypertension (PH) is prevalent and carries high morbidity and mortality, mostly due to right ventricular (RV) dysfunction. Postcapillary PH is the most frequent form but there are no large-animal models available. We developed and characterized a porcine model of postcapillary PH by non-restrictive banding of the confluent of both ...

microRNAs (miRNAs) are a class of small, non-coding RNAs that play critical posttranscriptional regulatory roles typically through targeting of the 3'-untranslated region of messenger RNA (mRNA). Mature miRNAs are known to be involved in global cellular processes, such as differentiation, proliferation, apoptosis, and organogenesis, due to their capacity to target ...
