Abstract:
Objective To explore the expression feature of long non-coding RNA (lncRNA) 1010001N08Rik in hyperoxia-induced bronchopulmonary dysplasia (BPD) and predict the mechanism that 1010001N08Rik might be involved in the occurrence and development of BPD by a series of bioinformatics analysis.Method The sequence,genomic position and structure characteristics of 1010001N08Rik were acquired from UCSC genome browser,and its target gene was predicted by Ensemble database.We successfully established the animal model of BPD by making newborn C57BL/6J mice exposed to 95％ concentrations of ambient oxygen for seven days.The expression of 1010001N08Rik and Gata 6 were detected using real-time quantitative polymerase chain reaction (PCR).Student's t test was used to compare their expression levels during the BPD process.Result The relative expression of 1010001N08Rik in BPD process at d1,d3,d5,d7 was 1.21 ± 0.33,2.02 ± 0.41,2.95 ± 0.45,4.20-± 0.48 respectively,and there were significant difference between adjacent time points (P ＜ 0.05).The relative expression of Gata 6 mRNA was 0.92 ±0.30,1.10 ± 0.31,0.86 ± 0.24,0.45-± 0.08 respectively,and there was significant difference between d5 and d7 (P ＜0.05).1010001N08Rik had highly conserved property among different species.The chromosomal regions of 1010001N08Rik existed transcriptional factors binding locations and epigenetic regulation clues,and its possible candidate target gene was Gata 6.Conclusion The expression of 1010001N08Rik increased during the formation process of BPD.Bioinformatics analysis and preliminary experiment results suggested that 1010001N08Rik might participate in the process of BPD by down-regulating Gata 6 expression.
