Non-biased genome-wide mRNA profiling of triazoloacridone C-1305 effects in human cell lines

ABSTRACT: In this study we used unbiased approach in the lung cancer and colon cell lines (A549 and HTC 116 respectively) to identify universal early transcriptomic signatures of C-1305 cytotoxicity, and to highlight novel pathways responsible for its biological activity. The data obtained with real time analysis was used to select appropriate doses for subsequent RNAseq and biochemical analysis. Furthermore, the RNA samples prior RNA-seq analysis were pre-verified for transcriptomic activation of apoptosis related pathways via qPCR . Since our real time analysis of cell growth have shown that 24 h exposure to C-1305 (at IC50 concentrations) is sufficient to significantly alter A549 and HTC 116 cells growth and to activate apoptosis-related transcriptional signals, we determined genome wide transcriptomic alterations in A549 and HTC 116 upon C-1305 treatment. In brief, A549 and HTC 116 cells were exposed to 3 µM or 10 µM of C-1305, respectively for 24 h day after plating. Furthermore, since our data have shown that 24 h exposure of noncancer cells epithelial lung cells 16HBE14o- to 3 µM C-1305 resulted in minimal cellular damage and loss of viability, we have included this treatment of 16HBE14o- as a negative control in our analysis. Finally, since genomic instabilities were reported for A549 cells to avoid related artifacts, DMSO vehicle treated cells (controls) were obtained after 24 h and after 8 h of cell culture. Total RNA was extracted from the cells after 24 h exposure to C-1305 and 24 h and/or 8 h exposure to vehicle and subjected to RNA sequencing.

Expression data from PrimeView human gene expression array

Project description:Gene expression in HCT-116 cells infected with shCtrl and shRFWD3 was detected with a PrimeView human gene expression array. We performed Affymetrix Human Gene Chip Prime View analysis on shCtrl and shRFWD3 HCT 116 cells. Of the 1305 differentially expressed genes (DEGs) found in shRFWD3 and shCtrl HCT 116 cells, 629 were up-regulated and 676 were down-regulated based on the threshold of absolute fold change ≥ 2 and FDR < 0.05

Identification of HLA class I-presented peptides in MSI CRC model cell line HCT-116

Project description:HCT-116 cells were treated either with 5 µM of the NMD inhibitor 5-azacytidine (PMID: 25319547) or DMSO (negative solvent control) for 24 h to examine differences in HLA class I-mediated peptide presentation. Moreover, data were used for the identification of tumor-specific neoepitopes originating from insertion/deletion mutations due to microsatellite instability.

Immunomodulatory, antioxidant, and potential anticancer activity of the polysaccharides of the fungus Fomitiporia chilensis

Project description:Fomitiporia species have aroused the interest of numerous investigations that reveal their biological activity and medicinal potential. The present investigation shows the antioxi-dant, anticancer, and immunomodulatory activity of acidic polysaccharides obtained from the fungus Fomitiporia chilensis. The acidic polysaccharides were obtained for acidic precipitation with 2% O-N-cetyl pyridinium bromide. Chemical analysis was performed by FT-IR and GC-MS methods. The antioxidant capacity of acidic polysaccharides from F. chilensis was evaluated by the scavenging of free radicals with the ABTS and DPPH as-says. Macrophages proliferation and cytokine production assays were used to determine the immunomodulatory capacity of the polysaccharides. Anti-tumor and cytotoxicity ac-tivity was evaluated with MTT assay in the U-937, HTC-116, and HGF-1 cell lines. The ef-fect of polysaccharides on the cell cycle of the HCT-116 cell line was determined for flow cytometry. Fourier Transform-infrared characterization revealed characteristic absorption peaks for polysaccharides, whereas the GC-MS analysis detected three peak correspond-ing to D-galactose, galacturonic acid and D-glucose. The TNF-α proliferation was in-creased when the cell was treated with 2 mg/mL polysaccharides, whereas the IL-6 con-centration was increased with all polysaccharide concentrations evaluated. The cell cycle analysis of HTC-116 treated with polysaccharides evidenced that the acidic polysaccha-rides from F. chilensis induce an increase in the G0/G1 cell cycle phase, incrementing the apoptotic cell percentage. A proteomic analysis suggested some of the molecular mecha-nisms involved in their antioxidant and cellular detoxifying effects and justified their tra-ditional use in heart diseases.

mRNA-sequencing of thyroid cancer cell lines

Project description:A metabolic hallmark of cancer identified by Warburg is the increased consumption of glucose and secretion of lactate, even in the presence of oxygen. Although many tumors exhibit increased glycolytic activity, most forms of cancer rely on mitochondrial respiration for tumor growth. We report here that Hürthle cell carcinoma of the thyroid (HTC) models harboring mitochondrial DNA-encoded defects in complex I of the mitochondrial electron transport chain exhibit impaired respiration and alterations in glucose metabolism. CRISPR-Cas9 pooled screening identified glycolytic enzymes as selectively essential in complex I-mutant HTC cells. We demonstrate in cultured cells and a PDX model that small molecule inhibitors of lactate dehydrogenase selectively induce an ATP crisis and cell death in HTC. This work demonstrates that complex I loss exposes fermentation as a therapeutic target in HTC and has implications for other tumors bearing mutations that irreversibly damage mitochondrial respiration.
