LncRNAs and mRNAs profile suggested CCL / CXCL were involved in the reoxygenation reversal of hypoxic pulmonary hypertension in mice


ABSTRACT: The potential roles of mRNAs and lncRNAs in the development and the reoxygenation treatment of reversal of hypoxic pulmonary hypertension are still unknown. 24 healthy adult male C57/BL6 mice were divided into three groups (normoxia group, hypoxia group, hypoxia-normoxia group), lncRNA and mRNA microarray was performed,meanwhile,the changes of right ven-tricular systolic pressure (RVSP) and other physiological indexes were measured in the three groups. The results showed that the index of RVSP, the right ventricular hypertrophy index RV/(LV+S), pulmonary artery walls and the muscularization ratio of pulmonary arterioles were significantly increased after Hypoxia treatment, while they were attenuated after the normoxia condition restored. Moreover, the study revealed there were 62 lncRNAs and 99 mRNAs with significant difference expression were associated with the reversal of hypoxic pulmonary hypertension by reoxygenation in mice. Furthermore, the pathway enrichment and gene ontology analysis of 99 DEGS were performed. Interestingly, the result suggested that chemokine subfamily CCL2/ CXCL played a role in the occurrence, development and reversion of pulmonary hypertension by reoxygenation. This study was the first time to demonstrate the transcriptome profiles of lncRNAs and mRNAs in the lung tissue during the reversal of hypoxic pulmonary hypertension in mice by reoxygenation, which might further broaden the understanding of the pathogenesis and the therapeutic effect of oxygen recovery of hypoxic pulmonary hypertension.
