Differential expression of circRNAs during rat lung development.

ABSTRACT: At present, thousands of circular RNAs (circRNAs) have been found in cancer and various tissues from different species. However, the expression of circRNAs during rat lung development remains largely unknown. In the present study, circRNA expression profiles were screened in three mixed rat lung tissues at 3 time‑points [embryonic day (E) 19, E21 and post‑natal (P) day 3] during fetal rat development with circRNA high‑throughput sequencing. Preliminary results were verified by reverse transcription‑PCR (RT‑PCR) at 4 time‑points (E16, E19, E21 and P3). A total of 375 circRNAs were differently expressed in E19 vs. E21 (fold change ≥1.5; P<0.05). At the same time, a total of 358 circRNAs were differently expressed in E21 vs. P3 (fold change ≥1.5; P<0.05). A total of 3 circRNAs (rno_circ:chr7:
