Project description:We sequenced mRNA from skeletal muscles derived from MYOD1-hiPSCs generated by different selection methods, and compared the results with those derived from human myoblast cell line (Hu5/KD3). This analysis enables us to understand the effects of different selection methods on the generation of MYOD1-hiPSCs and skeletal muscle differentiation from them. mRNAs from undifferentiated MYOD1-hiPSCs were also sequenced.(*RAW data not provided due to patient privacy concerns)

Project description:Purpose: The goals of this study are to compare the transcriptomic profile (mRNA-seq) of HD and control patient iPSC-derived neural cells to identify alterations in gene expression Methods: RNA were isolated from HD and control iPSC-derived neural cells. mRNAseq using Illumina Truseq mRNA PolyA+ v2 lib prep and Hiseq 2000. Statistical difference in mRNA levels were calculated with subsequent GO and pathway analysis Results: mRNAseq and statistical analysis revealed 1869 differentially expressed genes between HD and control iPSC-derived neural cells. Conclusions: Our study shows 1869 differentially expressed genes between HD and control iPSC-derived neural cells, and reveals gene networks that relevant to the mechanism of HD pathogenesis.

Project description:Basic helix-loop-helix (bHLH) pioneer transcription factors Myod1 and Ascl1 are biochemically related but produce fundamentally different outcomes when expressed in fibroblasts: Myod1 produces muscle cells and Ascl1 induces neurons. Here, we sought to investigate the molecular mechanisms explaining the differential activity. Surprisingly, we found a large overlap in the overall binding patterns of Ascl1 and Myod1 in fibroblasts, with both transcription factors accessing both neuronal and myogenic targets. We also observed similar changes in chromatin accessibility and transcriptional activation. Yet, Myod1 predominantly induced a muscle program and Ascl1 a neuronal program. We found that differences in binding affinity at key targets resulted in largely distinct reprogramming outcomes. Accordingly, exchanging Myod1’s C-terminal protein-protein interacting domain and DNA-binding basic domain with those of Ascl1 induces an Ascl1-like binding and converts Myod1 into a pro-neuronal factor. Finally, we found that co-expression of Myod1 with the transcriptional repressor Myt1l inhibits induction of the muscle program and yields functional neuronal cells. Our findings are compatible with the notion that pioneer factor activity is associated with high-affinity protein-DNA and suggest that promiscuous binding of pioneer factors can induce unspecific lineage features which need to be kept in check by co-factor interactions.
