(Submitter supplied) In order to examine how IOX1 affects the global Wnt target gene transcriptome in colorectal cancer cells, we performed RNA-sequencing in HCT116, DLD-1 and HCP-1 cells treated with IOX1. IOX1 led to global inhibition of Wnt target transcription in colorectal cancer cells.

(Submitter supplied) The impact of Mll1 removal on intestinal stem cells expressing an oncogenic form of beta-catenin (beta-cateninGOF) was analysed in 4 pairs of sorted intestinal stem cells of Lgr5-CreERT2; beta-cateninGOF;Mll1+/- (control) and Lgr5-CreERT2; beta-cateninGOF;Mll1-/- (knockout) at 10 days after tamoxifen-induced mutagenesis. Using 75-base-pair reads, around 30 million reads per sample with comparable unique mapped reads (73-78%) were obtained. more...

(Submitter supplied) The genetic programs that maintain leukemia stem cell (LSC) self-renewal and oncogenic potential have been well defined, however the epigenetic landscape that determines their cellular identity and functionality has not been established. We report that LSCs in MLL-associated leukemia are maintained in an epigenetic state defined by relative genome-wide high-level H3K4me3 methylation and low level H3K79me2. more...

(Submitter supplied) Cancer stem cells are characterized by their self-renewal properties and their ability to regenerate a tumor. They have chromatin features that are reminiscent of embryonic stem cells. Here, we link these stem cell-like characteristics of human glioblastoma initiating cells (GICs) to a loss of heterochromatin features. Increased histone H3 lysine 9 trimethylation (H3K9me3) levels due to histone demethylase inhibition led to cell death in GICs but not in their differentiated counterparts. more...

(Submitter supplied) We investigate RNA sequencing analysis revealed that the JIB-04 treatment altered the expression of genes that are involved in the cell cycle, apoptosis, and DNA replication and are also related to several cancers including colorectal cancer. JIB-04 also altered the expression of genes involved in various signaling pathways such as the MAPK signaling pathway, the PI3K-Akt signaling pathway, and the Wnt signaling pathway, which is crucial for the proliferation and maintenance of colorectal cancer cells.

(Submitter supplied) We performed genome-wide profiling of H3K9me3, H3K9me1, H3K27me3, and H3K36me3 by ChIP-seq in JMJD1C knockout or mutated MLL-AF9 leukemia cells. For ChIP-seq in JMJD1C mutated cells, we transduced sgRNA targeting the zinc finger, jumonji domain of JMJD1C or Renilla control and sorted on day 6 for GFP (MLL-AF9) Tdtomato (sgRNA) double positive cells. For ChIP-seq in JMJD1C knockout cells, we transduced Jmjd1c flox/flox MLL-AF9 leukemia cells with CRE TdTomato and sorted on day 6 for GFP (MLL-AF9) Tdtomato (CRE) double positive cells. more...

(Submitter supplied) We transduced clonally MLL-AF9 leukemia cells expressing cas9 with sgRNA targeting the jumonji and zinc finger domains of JMJD1C. GFP (MLL-AF9) and TdTomato (sgRNA) double positive cells were sorted on Day 6 after transduction. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed.

(Submitter supplied) To investigate the cooperative function KDM4D/NFIB/MLL1 complex in the regulation of adipogenic differentiation, we established 10T1/2 cell lines in which each target gene has been knocked down by shRNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at two time points.

(Submitter supplied) Transformed variant of H9 human ES cells (t-hESC) represent a surrogate model for cancer stem cells in adherent cultures, which faithfully recapitulate the main functional, transcriptional, and epigenetic characteristics of CSCs in culture and in vivo. The use of G9a inhibitor BIX-01294 reduced the levels of H3K9me2 and global DNA methylation in t-hESCs. Thus, we performed transcriptome-profiling experiments on control and BIX-treated t-hESC to study the impact of G9a inhibition on gene networks associated with neoplastic stemness. more...

(Submitter supplied) To analyze whether Wnt inhibitors LF3 and ICG-001 have similar influence on the gene expression of mouse salivary gland cancer stem cells Wnt/β-catenin signaling is a system that is essential for embryogenesis and tissue homeostasis which has been highly conserved through evolution. A deregulation of Wnt/β-catenin signals can initiate and promote human cancers, specifically of the colon, head and neck. more...

(Submitter supplied) We over-expressed an epigenetic regulator in a glioblastoma (GBM) primary culture from an adult patient. These GBM cells have cancer stem cell phenotypes, as they have self-renewal properties and tumor initiation potential when transplanted in immunocompromised mice. ATAC-seq was performed on cells over-expressing the epigenetic regulator and control cells expressing EGFP.

(Submitter supplied) Mutations in the histone 3 variant H3.3 have been identified in one-third of pediatric glioblastomas (GBMs), but not in adult tumors. Here we show that H3.3 is a dynamic determinant of functional properties in adult GBM. H3.3 is repressed by mixed lineage leukemia 5 (MLL5) in self-renewing GBM cells. MLL5 is a global epigenetic repressor that orchestrates reorganization of chromatin structure by punctuating chromosomes with foci of compacted chromatin, favoring tumorigenic and self-renewing properties. more...

(Submitter supplied) Mutant KRAS activates cancer stem cells (CSCs) contributing transformation of colorectal cancer (CRC) cells harboring adenomatous polyposis coli (APC) mutations. The factors mediating activation of CSCs by KRAS mutation were systematically investigated through a microarray analysis of the APC-mutated isogenic DLD-1 CRC cells harboring homogeneous wild-type KRAS (D-WT) or mutant KRAS (D-MT). The objective of the study was to find the factors specifically induced in the spheroids harboring both APC and KRAS mutations.

(Submitter supplied) In Drosophila, Polycomb Response Elements (PREs) are identified as genomic sequences allowing the maintenance of transcriptional repression in the absence of the initiating signal. Although PREs in Drosophila are well characterized, the existence of mammalian PRE-like elements remains debated. Accumulating evidence supports a model in which CpG islands function to recruit Polycomb-Group complexes (PcG), however, it is not evident which subclasses of CpG islands serve as PREs. more...
