Project description:Long noncoding RNAs (lncRNAs) have emerged as crucial regulators of gene expression during embryonic stem cell (ESC) self-renewal and differentiation. Here, we systemically analyzed the differentially regulated lncRNAs during ESC-derived cardiomyocyte (CM) differentiation. We established a perspicuous profile of lncRNA expression at four critical developmental stages and found that the differentially expressed lncRNAs were grouped into six distinct clusters. The cluster with specific expression in ESC enriches the largest number of lncRNAs. Investigation of lncRNA-protein interaction network revealed that they are not only controlled by classic key transcription factors, but also modulated by epigenetic and epitranscriptomic factors including N6-methyladenosine (m6A) effector machineries.

Project description:In vitro cardiac differentiation of human ESCs recapitulates in vivo embryonic heart development, and thus, serves as an excellent tool to investigate human cardiac development. Identification of molecular signatures during cardiac differentiation of human ESCs is instrumental for advancing our understanding of human cardiogenesis. We, as well as others have improved cardiac differentiation protocols significantly in recent years; however, detailed molecular mechanisms involved in cardiac lineage commitment have not yet been clearly defined. Based on this, we tried to identify the cellular hierarchies and molecular signatures of each of the in vitro human ESC-differentiating cardiac cell lineages through the well-established cardiac differentiatio protocol by Wnt signaling modulation and the FACS-sorted population RNA-seq analyses.

Project description:Cardiac maturation during perinatal transition of heart is critical for functional adaptation to hemodynamic load and nutrient environment. Perturbation in this process has major implications in congenital heart defects (CHDs). Transcriptome programming during perinatal stages is important information but incomplete in current literature, particularly, the expression profiles of the long noncoding RNAs (lncRNAs) are not fully elucidated From comprehensive analysis of transcriptomes derived from neonatal mouse heart left and right ventricles, a total of 45,167 unique transcripts were identified, including 21,916 known and 2,033 novel lncRNAs. Among these lncRNAs, 196 exhibited significant dynamic regulation along maturation process. By implementing parallel weighted gene co-expression network analysis (WGCNA) of mRNA and lncRNA datasets, several lncRNA modules coordinately expressed in a developmental manner similar to protein coding genes, while a few of them revealed chamber specific patterns. Out of 2,442 lncRNAs located within 50 KBs of protein coding genes, 11% significantly correlates with the expression of their neighboring genes. The impact of Ppp1r1b-lncRNA on the corresponding partner gene Tcap was validated in cultured myoblasts. While this concordant regulation was also conserved in human infantile hearts. Furthermore, the Ppp1r1b-lncRNA/Tcap expression ratio was identified as a molecular signature that differentiated CHD phenotypes lncRNA dataset: neonatal mouse heart left and right ventricles

Project description:Cardiac fibrosis occurs in most cardiac diseases, which reduces cardiac muscle compliance, impairs both systolic and diastolic heart function and, ultimately, leads to heart failure. Using unbiased transcriptome profiling in a mouse model of myocardial infarction, we identified a cardiac-fibroblast enriched lncRNA (AK048087) named cardiac fibroblast-associated transcript (Cfast), which is significantly elevated after myocardial infarction. Here, we show that silencing Cfast expression by lentiviral shRNAs resulted in suppression of fibrosis-related gene expression and transdifferentiation of myofibroblasts into cardiac fibroblasts. We performed the RNA-seq profiling in both lentivirus Cfast knockdown and lentivirus scramble group in cardiac fibroblasts. Finally, the transcriptome analysis indicates that genes related to cell differentiation, cell migration, extracellular matrix organization downregulated in Cfast knockdown group.

Project description:We interrogated the genome-wide occupancy of histone modifications and RNA polymerase II at several stages of an mouse embryonic stem cell to cardiomyocyte directed differentiation protocol. These four stages represent timepoints when differentiating cultures are enriched for embryonic stem cells (ESC), mesodermal cells (MES), cardiac precursors (CP), or cardiomyocytes (CM) respectively. This study revealed many dynamic patterns of histone modifications during differentiation that are coordinated with stage-specific gene expression including a novel preactivation chromatin pattern found at genes associated with cardiac function. In addition, this study identified distal enhancer elements and enriched transcription factor motifs within enhancer regions for each stage of differentiation, which were used to predict novel transcription regulatory networks.
