Transcription profiling by array of mouse main branch pulmonary artery to study the differences between wild type and miR-145 KO mice exposed to normoxic or hypoxic conditions

ABSTRACT: Hypoxia is used as a model for pulmonary arterial hypertension. MiR-145 is upregulated in pulmonary arterial hypertension in humans and female mice. It has been observed that miR-145 knock out mice have reduced vascular remodelling in response to hypoxia. Therefore, knock down of miR-145 could be used as a therapy for pulmonary arterial hypertension in humans. This microarray has helped us to elucidate some of the pathways in the miR-145 knock out mice that may protect against vascular remodelling. Wild type (WT) mice and homozygous miR-145 -/- female mice (strain C57BL6J/129SVEV) at 8 weeks old were exposed to chronic hypoxia for 2 weeks or maintained in normoxic conditions and pulmonary arteries were dissected at 10 weeks of age. This study contained 4 groups, WT hypoxic, WT normoxic, miR-145 -/-, hypoxic miR-145 -/- normoxic each containing 6 animals. All adjacent comparisons were made to ananlyse the data (a 2 by 2 design).
