Abstract
A single-nucleotide polymorphism (SNP) is an alteration in one nucleotide in a certain position within a genome. SNPs are associated with disease susceptibility. However, the influences of SNPs on the pathogenesis of neonatal hypoxic-ischemic brain damage remain elusive. Seven-day-old rats were used to establish a hypoxic ischemic encephalopathy model. SNPs and expression profiles of mRNAs were analyzed in hypoxic ischemic encephalopathy model rats using RNA sequencing. Genes exhibiting SNPs associated with hypoxic ischemic encephalopathy were identified and studied by gene ontology and pathway analysis to identify their possible involvement in the disease mechanism. We identified 89 up-regulated genes containing SNPs that were mainly located on chromosome 1 and 2. Gene ontology analysis indicated that the up-regulated genes containing SNPs are mainly involved in angiogenesis, wound healing and glutamatergic synapse and biological processing of calcium-activated chloride channels. Signaling pathway analysis indicated that the differentially expressed genes play a role in glutamatergic synapses, long-term depression and oxytocin signaling. Moreover, intersection analysis of high throughput screening following PubMed retrieval and RNA sequencing for SNPs showed that CSRNP1, DUSP5 and LRRC25 were most relevant to hypoxic ischemic encephalopathy. Significant up-regulation of genes was confirmed by quantitative real-time polymerase chain reaction analysis of oxygen-glucose-deprived human fetal cortical neurons. Our results indicate that CSRNP1, DUSP5 and LRRC25, containing SNPs, may be involved in the pathogenesis of hypoxic ischemic encephalopathy. These findings indicate a novel direction for further hypoxic ischemic encephalopathy research. This animal study was approved on February 5, 2017 by the Animal Care and Use Committee of Kunming Medical University, Yunnan Province, China (approval No. kmmu2019038). Cerebral tissue collection from a human fetus was approved on September 30, 2015 by the Ethics Committee of Kunming Medical University, China (approval No. 2015-9).

Abstract
Ischemia-induced stroke is the most common disease of the nervous system and is associated with a high mortality rate worldwide. Cerebral ischemia may lead to remote organ dysfunction, particular in the lungs, resulting in lung injury. Nowadays, bone marrow-derived mesenchymal stem cells (BMSCs) are widely studied in clinical trials as they may provide an effective solution to the treatment of neurological and cardiac diseases; however, the underlying molecular mechanisms remain unknown. In this study, a model of permanent focal cerebral ischemia-induced lung injury was successfully established and confirmed by neurological evaluation and lung injury scores. We demonstrated that the transplantation of BMSCs (passage 3) via the tail vein into the lung tissues attenuated lung injury. In order to elucidate the underlying molecular mechanisms, we analyzed the gene expression profiles in lung tissues from the rats with focal cerebral ischemia and transplanted with BMSCs using a Gene microarray. Moreover, the Gene Ontology database was employed to determine gene function. We found that the phosphoinositide 3-kinase (PI3K)-AKT signaling pathway, transforming growth factor-β (TGF-β) and platelet-derived growth factor (PDGF) were downregulated in the BMSC transplantation groups, compared with the control group. These results suggested that BMSC transplantation may attenuate lung injury following focal cerebral ischemia and that this effect is associated with the downregulation of TGF-β, PDGF and the PI3K-AKT pathway.
