Gene expression in xenograft tumors derived from HCT116 and its oxaliplatin resistant clones

Project description:To explore the mechanisms associated with oxaliplatin resistance, we compared gene expression in xenograft tumors derived from human colorectal cancer tumor cells HCT116 and its oxaliplatin resistant clones (HCT/OHP1 and HCT/OHP5).

Differential ncRNAs of oxaliplatin-resistant versus parental HCT116 cells

Project description:Oxaliplatin resistance frequently leads to therapeutic failure in colorectal cancer (CRC). Increasing evidence has shown that noncoding RNAs (ncRNAs) play pivotal roles in chemoresistance of CRC. However, the roles and mechanisms of ncRNAs in oxaliplatin resistance are not well understood. In this study, to identify the ncRNAs induced by oxaliplatin, we profile the expression of ncRNAs in oxaliplatin-resistant HCT116 CRC cells (HCT116oxR) and parental HCT116 cells using next-generation sequencing technology.

Transcription profiling of QUB HCT116 sensitive and resistant colorectal cancer time series

Project description:HCT116 parental, HCT116 5-FU resistant and HCT116 oxaliplatin resistant cells have been transiently treated with with their respective drug (5-FU or oxaliplatin) for 0, 6 12 or 24h in 3 independent experiments.

RNA-Seq of Oxaliplatin-treated HCT116 human colon cancer cells

Project description:Aim: mRNA profile of HCT116 human colon cancer cells to study the early response of cells to oxaliplatin exposure at low doses (0.5µM) Results: After treatment with oxaliplatin for 24h at 0.5µM, only a very small fraction of genes were mis-regulated. They fall mainly include P53-response genes, genes regulating inflammation, or genes regulating cytoskeleton.

YTHDF3 improves translation initiation of mRNAs with N6-methyladenosine methylation at 5’ untranslated region by facilitating eIF2AK2 recruitment in oxaliplatin-resistant colorectal cancer - RIP-seq dataset

Project description:Oxaliplatin as a first-line drug frequently causes the chemo-resistance on colorectal cancer (CRC). N6-methyladenosine (m6A) methylation has been largely acknowledged in multiple biological functions. However, the molecular mechanisms underlying the m6A methylation in modulating anticancer drug resistance in CRC are still obscure. In present study, RIP-seq was conducted to investigate the occupancy of N6-methyladenosine RNA binding protein 3 (YTHDF3) served as “readers” that can recognize m6A modification site in HCT116 cells with oxaliplatin resistance (HCT116R). Then, YTHDF3 was knockdown by siRNA in HCT116 cells with oxaliplatin resistance, and RIP-seq was further conducted to investigate m6A methylation of HCT116, HCT116R and HCT116R cells with YTHDF3 knockdown.

High-throughput sequencing analysis of miRNAs expression profiles in the HCT116 colorectal cancer sublines resistant to oxaliplatin (Oxa) or 5-fluorouracil (5-FU).

Project description:In the present study, we investigated miRNA expression changes caused by aquired chemoresistance to 5-FU or Oxa. 40 and 14 miRNAs were detected as differentially expressed in 5-fluouracil- and oxaliplatin-resistant colorectal HCT116 sublines, respectively. Differentially expressed miRNAs determined in the present study could be applied for further development of diagnostic and therapeutic applications for colorectal cancer carcinoma resistant to 5-FU or Oxa.

Gene expression profiling of CYC116 and ZM447439 resistant HCT116 wild type and HCT116 p53 null clones in comparison to parent cell lines

Project description:HCT116 and HCT116 p53 null were exposed to two Aurora kinase inhibitors (CYC116 and ZM447439) at cytotoxic concentrations. Within 4-5 weeks we were able to select and isolate 10 drug resistant clones from each group. 3 clones were selected for gene expression profiling using Affymetrix microarrays (Human Gene 1.0 ST Array). The samples in each group were initially given the code names as follows. Group 1. [R1.3, R4.2, R6.3: CYC116 p53 wild type], Group 2. [R8.7, R9.7, R10.7:CYC116 p53 null], Group 3. [R7.1, R15.1, R16.1:ZM447439 p53 wild type], and Group 4. [R1.5, R3.5, R4.5:ZM447439 p53 null). For publication purpose the names were later changed to, Group 1. [R1.1, R1.2, R1.3: CYC116 p53 wild type], Group 2. [R2.1, R2.2, R2.3:CYC116 p53 null], Group 3. [R3.1, R3.2, R3.3:ZM447439 p53 wild type], and Group 4. [R4.1, R4.2, R4.3:ZM447439 p53 null].
