(Submitter supplied) HIF-1α plays a crucial role in sustaining glioblastoma (GBM) cell growth and the maintenance of their undifferentiated phenotype. However, HIF-1α has been suggested to interplay with Wnt signaling components, thus activating a neuronal differentiation process in both GBM and normal brain. Here, we show that a β-catenin/TCF1/HIF-1α complex directly controls the transcription of neuronal differentiation genes in hypoxia. more...

(Submitter supplied) Glioblastoma Multiforme (GBM) is the primary brain tumor with the highest incident and mortality rates worldwide. This is because therapies are not effective, mainly due to tumor recurrence after surgical resection and chemotherapeutic treatment. Recurrence is mainly produced by a tumoral cell sub-population called Glioblastoma Stem-like Cells (GSCs), which are primarily responsible for chemo-resistance and tumor infiltration. more...

(Submitter supplied) Quiescent stem cells of glioblastoma (GBM), a malignant primary brain tumor, are potential sources for recurrence after therapy. However, the gene expression program underlying the physiology of GBM stem cells remains unclear. We have isolated quiescent GBM cells by engineering them with a knock-in H2B-GFP proliferation reporter and expanding them in a 3D tumor organoid model that mimics tumor heterogeneity. more...

(Submitter supplied) HIF1α promotes glioblastoma cell proliferation and tumorigenesis under hypoxia conditions, leading to poor prognosis; however, none of the targeted therapies of HIF1α for glioblastoma is success nowadays. Therefore, we focused to look for the reason and wondered whether HIF2α contributed GBM growth. We did gene-chip and found that HIF2α contributed to the malignant progression of glioblastoma while blocking of HIF1α. more...

(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.

(Submitter supplied) Primary glioblastoma (GBM) cultures vary with respect to differentiation competency. 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) Making use of a previously described isogenic cancer stem cells and serum differentiated cultures we show that Sox2 controls developmental stated specific programs in glioblastoma. Glioblastoma cells were cultured as control and with SOX2 knockdown to identify the scope of SOX2 interactions. The SOX2 knockdown were accomplished using two knockdown technologies. The knockdown cells were compared to controls, early passage, and scrambled controls. more...

(Submitter supplied) Developmental fate decisions are dictated by master transcription factors (TFs) that interact with cis-regulatory elements to direct transcriptional programs. Certain malignant tumors may also depend on a cellular hierarchy reminiscent of normal development but superimposed on underlying genetic aberrations. In glioblastoma (GBM), a subset of stem-like tumor- propagating cells (TPCs) appears to drive tumor progression and underlie therapeutic resistance, yet remain poorly understood. more...

(Submitter supplied) Ovarian cancer (OC) is the most lethal gynecological cancer due to its late diagnosis and, importantly, its high rate of chemoresistance. Hypoxia in solid tumors is an important source of chemoresistance that can determine poor patient prognosis. Such chemoresistance relies on the presence of cancer stem cells (CSCs), and hypoxia promotes their generation through transcriptional activation by HIF transcription factors. more...
