Bioinformatic and Expression Analysis of Ventricular Septal Defect-associated Long Non-coding RNA TUC40-.

To explore the potential role of TUC40- in human and mouse embryonic heart development.,Bioinformatics databases including NCBI,UCSC,and Uniprot and software including Clustal,DNAMAN,and MEGA 6 were used to collect information of TUC40- and uc.40-. The expression profile at key time points of heart development was investigated by strand-specific quantitative real time polymerase chain reaction.,Uc.40- was conservative in sequence, genomic location, and transcription factor binding sites across human and mouse. Pbx1/TUC40- showed negative trend during embryonic mouse heart maturation.,Various levels of conservation of uc.40- suggests similar functions of TUC40- in these two species. TUC40- may play its roles in human and mouse embryonic heart development by regulating Pbx1.
