Transcriptome analysis of novel CPT-CEF-treated HT29 colon cancer cells to evaluate drug cytotoxicity

ABSTRACT: Purpose: To identify differentially expressed genes in HT29 colon cancer cells after treatment with a novel formulation of camptothecin with β-cyclodextrin-EDTA-Fe3O4 nanoparticle-conjugated nanocarriers (CPT-CEF) Methods:Treated HT29 cell lines with CPT-CEF, isolated total RNA from HT29 colon cancer cells, and prepared library for RNA sequencing. Carried out comparative transcriptomic studies between treated and untreated cells to find out which gene functions were dysregulated by CPT-CEF. Results: The study yielded 247 DEGs ((FDR<0.05, FC>2.0) that were affected by CPT-CEF treatment in the HT29 colon cancer cells. The results obtained from cell cycle analysis, mitochondrial depolarization assay and acridium orange/propidium iodide double staining showed potential of CPT-CEF in cancer cell inhibition. Conclusion: Our study successfully identified DEGs in the CPT-CEF treated HT29 colon cancer cells that pointed to inhibition of cancer progression. To further affirm, animal studies are needed.

Blockade of intrinsic PD-1 promotes survival, chemo resistance and tumor growth in human colon cancer

Project description:Human colon cancer cells HT29, HCT116, LoVo robustly expressed PD-1. PD-1 signaling significantly decreased proliferation and promoted apoptosis in PD1+human colon cancer cells. The human anti-PD-1, Nivolumab (NIVO) ptomoted proliferation through pERK/pAKT signaling, reduced apoptosis and protected PD-1+ cells from Chemo/Radiotherapy (CRT). In vivo, NIVO promoted HT29 tumor growth reducing Oxaliplatin (OX) efficacy. As opposite to colon cancer cells, PD-1 signaling protects melanoma cells, thus NIVO treated human colon versus melanoma cancer cells, PES43 were evaluated for RNAseq. Among the commonly affected genes, opposite regulation was revealed between HT29 and HCT116 colon versus PES43 melanoma cells. BATF2, DRAM1, FXYD3, IFIT3, MT-TN, TNFRSF11A were upregulated in PES43 and downregulated in HT29 and HCT116 while CLK1, DCAF13, DNAJC2, MTHFD1L, PRPF3, PSMD7, SCFD1 were downregulated in PES43 and upregulated in HT29 and HCT116. DEGs were significantly enriched in the functional categories of the interferon pathway, innate immune, cytokine-mediated signaling pathway, neutrophil activation, immune effector process, granulocyte activation and cellular nitrogen compound metabolic process. Moreover, intrinsic PD-1 was expressed in 11/48 (22.9%) primary colorectal cancer and associated with tumor dimension (pT). Thus, PD-1 inhibition through NIVO protects human colon cancer cells and activate tumor survival pathways

Colon cancer shperes are sensitive to Fenretinide

Project description:Fenretinide has shown its antitumor activity in many tumor types with low cytotoxicity to normal cells. Recently, we have shown that fenretinide could eradicate chronic myeloid leukemia stem/progenitor cells and spheres from ovarian cancer. In this study, we investigate whether fenretinide could selectively target sphere cells of colon cancer. Using high-throughtput microarray system, we identified GO terms and pathway signatures enriched in fenretinide treated HT29 cells and HT29 derived sphere cells. Colon cancer cells HT29 were cultured in sphere formation conditions, HT29 cells and HT29 derived sphere cells were treated with fenretinide, and total RNA from those spheres and corresponding adhered cell was hybridized on Affymetrix U133 plus 2.0 genechip.

The antidepressant fluoxetine elicits anticancer effects by impairing aerobic glycolysis in colon cancer cells and xenografts.

Project description:Colon cancer is one of the most common tumors worldwide. Recent reports showed that patients treated with the antidepressant fluoxetine had reduced colon cancer risk, with effects similar to the chemotherapeutic 5-fluoro-uracil. Here, we examined the effects of fluoxetine and 5-fluoro-uracil on gene expression of HT29 colon cancer cell xenografts. HT29 xenografts in NOD/SCID mice were treated with vehicle (physiological solution), fluoxetine (30mg/kg/day), or 5-Fluoro-uracil (50 mg/kg/day).

Transcriptomic comparison of chemosensitive and chemoresistant cells

Project description:First, in a model of xenografts induced with HT-29 human colon cancer cells, we demonstrated that the transcription factor NF-kB was involved in the resistance to CPT-11. Then, from one tumor treated with CPT-11 plus a NF-kB inhibitor, we established a resistant cell line to CPT-11. The aim of this study was to compare the expression of genes involved in the signaling pathway of NF-kB between the sensitive and the resistant cell lines and to identify other genes (target or not of NF-kB) which the expression was modified when the resistant phenotype was acquired. Human colon cancer cells chemosensitive (HT-29) versus human colon cancer cells chemoresistant (RIV) in a dye-swap experiment.

Epiploic Adipose Tissue (EPAT) in Obese Individuals Promotes Colonic Tumorigenesis: A Novel Model for EPAT-Dependent Colorectal Cancer Progression

Project description:The obesity epidemic is associated with increased colorectal cancer (CRC) risk and progression, the mechanisms of which remain unclear. In obese individuals, hypertrophic epiploic adipose tissue (EPAT), attached to the colon, has unique characteristics compared to other fats. We hypothesized that this understudied fat could serve as a tumor-promoting tissue and developed a novel microphysiological system (MPS) for human EPAT-dependent colorectal cancer (CRC-MPS). In CRC-MPS, obese EPAT, unlike lean EPAT, considerably attracted colon cancer HT29-GFP cells and enhanced their growth. Conditioned media (CM) from the obese CRC-MPS significantly increased the growth and migration of HT29 and HCT116 cells (p< 0.001). In HT29 cells, CM stimulated differential gene expression (hOEC867) linked to cancer, tumor morphology, and metabolism similar to those in the colon of high-fat-diet obese mice. The hOEC867signature represented pathways found in human colon cancer. In unsupervised clustering, hOEC867separated transcriptomes of colon cancer samples from normal with high significance (PCA,p =9.6 × 10−11). These genes, validated in CM-treated HT29 cells (p< 0.05), regulate the cell cycle, cancer stem cells, methylation, and metastasis, and are similarly altered in human colon cancer (TCGA). These findings highlight a tumor-promoting role of EPAT in CRC facilitated with obesity and establishes a platform to explore critical mechanisms and develop effective treatments.

Transcription profiling of Zea mays embryos under camptothecin (CPT) treatment.

Project description:Camptothecin (CPT) is a plant alkaloid that specifically binds topoisomerase I (Topo I) inhibiting its activity and inducing double stranded breaks in the DNA, activating the genotoxic cell responses, and ultimately, it might trigger programmed cell death (PCD). We used microarrays to detail the changes in gene expression during as a consequence of CPT treatment in maize immature embryos. In four independent experiments immature embryos were plated on MS medium supplemented with 50 uM CPT and incubated during three days. Untreated embryos incubated on MS medium were used as controls.
