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: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: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.
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:Purpose: Assess the transcriptional changes induced upon RAB7 knock-down in melanoma (SK-Mel-28 and UACC-62) and in colon cancer (HCT-116) cell lines. Methods: mRNA profiles of tumor cell lines (SK-Mel-28, UACC-62, HCT-116) stably expressing scrambled shRNA or RAB7 shRNA (harvested at day 3 after lentiviral infection) were generated by deep sequencing, using three biological replicates per condition. The sequence reads that passed quality filters were analyzed with TopHat and Cufflinks. Validation of induced / silenced genes was performed by western blot. Results show a differential impact of RAB7 expression in the transcriptomic profile of melanoma vs non-melanoma cell lines, and support a lineage-specific role of this small GTPase in melanoma. Examination of the mRNA profiles RAB7-depleted vs wild type cells, performed in parallel in 3 different tumor cell lines (Melanomas: SK-Mel-28 and UACC-62, Non-melanoma: HCT-116) harvested at day 3 after lentiviral infection.
Project description:Extracellular vesicles (EVs) play a crucial role in facilitating intercellular communication. The microRNA profiles carried by EVs often exhibit variations between tumor patients and healthy individuals, making them promising biomarkers. These biomarkers are implicated in oncogenic processes and tumor metastasis upon uptake by recipient cells. To investigate the impact of EV biomarkers on tumorigenesis, we exposed HCT-116 cell lines to EVs isolated from the serum of both tumor patients and healthy individuals. In comparison to cell lines treated with extracellular vesicles (EVs) from healthy individuals and blank controls, cell lines treated with EVs from HCC sources exhibit significant alterations in the expression of certain genes associated with pathways related to liver cancer. Our findings shedlight on the intricate interplay between EVs and tumor progression.
Project description:We report the differential gene expression upon the LPA treatment depicting the invasion/metastasisphenomenon and the lipogenesis effect on the colorectal cancer cells HCT-116
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.
