yylncT acts as a gatekeeper of the mesodermal transcriptional program by local modulation of DNMT3B [human_1]
Bidirectional transcription is a prevalent feature of eukaryotic promoters. The goal of this study is to identify novel divergent long-coding RNAs during differentiation of human ES to cardiomyocytes. Methods: Paired end RNA-Seq was performed on key time-points of human ES cell differentiation to cardiomyocytes. The time-points include day 0, day 1, day 2, day 4,day 6, day 8 and day 14. Results: Using an optimized data analysis workflow, we mapped about ~70 million sequence reads per sample to the human genome (build hg38) and identified 781 novel yylncRNAs during ES cell differentiation to cardiomyocytes. Expression kinetics of a subset of  yylncRNAs identified from RNA-Seq  had a linear relationship with qRT–PCR . Conclusions: Our study represents the detailed analysis of the genome wide identification of divergent long-coding RNA generated by paired end RNA-seq technology. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of long-non coding RNA content in the process of cardiac differentitation. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biological functions. Overall design: We have used 7 different time-point (all in triplicates), covering key stages of human  ES cell differentiation to cardiomyocytes. It includes day 0 (ES cells), day 1(   early mesoderm), day 2 (late mesoderm), day 4 (cardiac mesoderm), day 6 (cardiac progenitors), day 8 (early cardiomyocytes) and day 14 (cardiomyocytes).
