Project description:The transcriptional profiles of the HCT116 parental cells following treatment with either 5-FU or SN38 for 24h were assessed. In addition, basal comparisons between HCT116 parental and HCT116 5-FU -resistant and HCT116 SN38-resistant cells were also assessed.

Project description:Copy number profiling of MKN45T 5-FU resistant gastric cancer cell lines and its parental cell line MKN45. We hypothesized that a detailed fine-scale survey of genomic CNAs might reveal the mechanism for acquired resistant to 5-FU in gastric cancer.

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.

Project description:Parental and 5-fluorouracil (5-FU)-resistant HCT15 cells were treated with 5-FU or vehicle for 12h and assembled into an IMPRINTS-CETSA scheme with 6 different heating temperatures (37ºC, 47ºC, 50ºC, 52ºC, 54ºC, and 57ºC) with each set of samples heated at one temperature included in the same isobaric TMT10 set and measured at the same time on the mass spectrometer.

Project description:5-Fluorouracil (5-FU) is one of the most common drugs used in chemotherapy because of its efficacy and stability. However, 5-FU has been known to work on only 10~15% of colon cancer patients. Therefore, the study of 5-FU sensitivity study is necessary to increase the survival of colon cancer patients. p53 is one of the factors that effect on drug sensitivity. Main function of p53 has been focused on transcription activity in cell death. Numerous drug related studies show that expression of wild-type p53 increases drug sensitivity in various cancer types through inducing apoptotic signaling pathways. Currently, it has been reported that p53 has both transcriptional and non-transcriptional activities in apoptosis. However, most studies about p53 non-transcriptional activities in apoptosis are mainly focused on p53 induced mitochondrial outer membrane permeabilization, triggering the release of pro-apoptotic factors. The chromatin structure and organization have strongly attracted because of their impacts in cellular phenotypes. Recent studies have been shown that changes in chromatin accessibility affect cell phenotypes for external stimuli. Since p53 plays an important role in drug sensitivity and 5-FU is an external stimulus for cancer cells, we hypothesized that p53 may effect on 5-FU sensitivity through different regulation of chromatin accessible regions between TP53-WT and TP53-KO cells. To determine the effect of p53 on chromatin accessibility modification associated with 5-FU sensitivity, ATAC-seq and RNA-seq were performed under 5-FU treatment on TP53-WT as drug sensitive and TP53-KO as drug resistant HCT116 cells. In this study, we found that 5-FU induces chromatin accessibility in both TP53-WT and TP53-KO cells. Moreover, our results show that 5-FU induced chromatin accessibility increases expression of apoptotic genes in TP53-WT HCT116 cells through p53 non-transcriptional activity in nucleus.
