(Submitter supplied) ASCL1 mediates neuronal differentiation of GBM stem cell (GSC) cultures. We sought to identify chromatin changes upon induced ASCL1 expression in primary human GSC cultures. In this dataset, we include ATAC-seq data obtained from GSC cultures harbouring a CRISPR-deletion of ASCL1. We assessed differential ASCL1 binding between control and GSC cultures induced to overexpress ASCL1 after 14 days of doxycycline treatment.

We sought to identify putative transcription factors necessary for the differentiation of GBM cultures. In this dataset, we include expression data obtained from 2 human-fetal neural stem cell (HF-NS) cultures and 2 GBM stem cell (GSC) cultures. We assessed changes in gene expression from 3 timepoints during an in vitro differentiation protocol.

(Submitter supplied) ASCL1 mediates neuronal differentiation of GBM stem cell (GSC) cultures upon Notch signalling inhibition. We sought to identify gene expression changes that were specific to ASCL1 function. In this dataset, we include RNA-seq data obtained from GSC cultures harbouring wildtype or CRISPR-deletion of ASCL1. We assessed differential gene expression between wildtype and ASCL1-knockout after treatment with gamma-secretase inhibitor for 7 days.

(Submitter supplied) ASCL1 is known to act as transcriptional activator of notch signaling pathway. We have found that ASCL1 is over expressed in secondary glioblastoma. In order to delineate its functional role in gliomagensis we have used gene silencing approach to identify genes differentially regulated upon ASCL1 down regulation in U87MG glioma cell line.

(Submitter supplied) ASCL1 is a neuroendocrine-lineage-specific oncogenic driver of small cell lung cancer (SCLC), highly expressed in a significant fraction of tumors. However, ~25% of human SCLC are ASCL1-low and associated with low-neuroendocrine fate and high MYC expression. Using genetically-engineered mouse models (GEMMs), we show that alterations in Rb1/Trp53/Myc in the mouse lung induce an ASCL1+ state of SCLC in multiple cells of origin. more...

(Submitter supplied) Small cell lung cancer (SCLC) is a neuroendocrine tumor treated clinically as a single disease with poor outcomes. Distinct SCLC molecular subtypes have been defined based on expression of lineage-related transcription factors: ASCL1, NEUROD1, POU2F3 or YAP1, but their origins remain unknown. We developed an in vitro model of MYC-driven SCLC tumor cell progression, and performed a time-series analysis of single-cell transcriptome profiling to reveal that MYC drives the dynamic evolution of SCLC subtypes. more...

(Submitter supplied) Distinct SCLC molecular subtypes have been defined based on expression of lineage-related transcription factors: ASCL1, NEUROD1, POU2F3 or YAP1, but their origins remain unknown. To study transcriptional dynamics of MYC-driven tumor evolution and compare transcriptional states to human SCLC tumors, we performed bulk and single-cell RNA-sequencing on various timepoints of Rb1/Trp53/MycT58A (RPM) tumor cells (from Ad-Cgrp-Cre infected mice) as they progress in culture, and on RPM bulk tumors. more...

(Submitter supplied) Extensive genomic studies support the classification of small cell lung cancer (SCLC) into subtypes based on expression of lineage-defining transcription factors including ASCL1 and NEUROD1, which together account for ~80% of this disease. ASCL1 and NEUROD1 activate SCLC oncogene expression and drive distinct transcriptional programs. ASCL1 is also required for tumorigenesis in SCLC mouse models, and both ASCL1 and NEUROD1 maintain the in vitro growth and oncogenic properties of ASCL1+ or NEUROD1+ SCLC cell lines. more...
