Project description:HCT-116 cell lines were treated with bPGN and treated cells were harvested at time-point 0, 1hour and 24hours. Identification of RNA-interacting pharmacophores could provide new chemical probes and potentially novel RNA-based therapeutics. Herein, using a high-throughput differential scanning fluorimetry assay, we identified small molecule natural products with the capacity to bind the discrete stem-looped structure of pre-miR-21. The most potent compound identified was a prodiginine-type compound, butylcylcoheptyl prodiginine (bPGN), with the ability to inhibit Dicer-mediated processing of pre-miRNA-21 in vitro and in cells. Time dependent RT-qPCR, western blot, and transcriptomic analyses showed modulation of miR-21 expression and its target genes such as PDCD4 and PTEN upon treatment with bPGN, supporting on-target inhibition. Consequently, inhibition of cellular proliferation in HCT-116 colorectal cancer cells was also observed when treated with bPGN. The discovery that bPGN can bind and modulate the expression of regulatory RNAs such as miR-21 helps set the stage for further development of this class of natural product as a molecular probe or therapeutic agents against miRNA-dependent diseases.

Project description:Anti-APC ChIP-seq data were collected from HCT-116 cells and 3,985 genomic sequences were found to be enriched in both independent biological replicates.
Project description:The study aim is to evaluate to what extent imipramine treatment of HCT-116 colorectal cell lines does affect fascin1-related or cytoskeleton-associated functions
Project description:To understand molecular mechanisms underlying the growth inhibitory ativity of Stearoyl-CoA desaturase-1 (SCD1) inhibitor, we performed microarray analysis using HCT-116 colorectal cancer cells, in which SCD1 was pharmacologically blocked or genetically ablated.
Project description:Che-1 is a RNA Polymerase II binding protein involved in the regulation of gene transcription. Che-1 emerges as an important adaptor that connects transcriptional regulation, cell-cycle progression, checkpoint control, and apoptosis. We have observed that Che-1 depletion sensitizes cells to chemotherapy. We used microarrays analysis to investigate classes of genes regulated by Che-1. Total RNA was extracted from control and Che-1 depleted HCT 116 cells 48 hours after transient transfection of siRNA.

Project description:We examined the alternation of gene expression by MCC-555, rosiglitazone (RGZ) and 15-deoxy-Δ12, 14-prostaglandin J2 (PGJ2) in human colorectal adenocarcinoma HCT-116 cells. Keywords: effects of PPAR-gamma agonists
Project description:Gene expression data were collected by RNA-seq from HCT-116 cells in the presence or absence of siRNA targeting APC and 1,376 transcripts changed in expression following APC silencing were identified relative to scrambled siRNA-transfected and untreated controls.
Project description:HT-29 and HCT-116 cells were barcoded using the CloneTracker lentiviral barcode library and then dabrafenib and irinotecan resistant derivatives of these cell lines were established, respectively.10 million barcoded HT-29 and HCT-116 cells were seeded equally onto poly-HEMA coated 4xT75 flask (DMSO Control, Replica A, B, C for each drug). After seeding, cells were allowed to form spheroids and barcoded 3D-HT-29 spheroids were treated with dabrafenib at increasing doses starting from IC50/10 dose until IC50/2 dose with monthly doubling of the dosing (16 weeks), and barcoded 3D-HCT-116 cells were treated with irinotecan at increasing doses starting from IC50/4 dose until IC50 dose with weekly doubling of the dosing (4 weeks). Following the end points of treatment for each cell line, DNA was isolated from harvested cell lines and barcode sequencing and whole exome sequencing were carried out.
