ChIP-Seq of DNA lesions from irradiated and non-irradiated HaCaT cells

ABSTRACT: This study aims to investigate the binding DNA lesions of AIM2 in HaCaT cells exposed to 0Gy and 20Gy by ChIP-Seq. In this study, HaCaT cells were maintained in DMEM. All culture media were supplemented with 10% fetal bovine serum (FBS; Biological Industries, Kibbutz Beit-Haemek, Israel). Cells were grown at 37 °C in 5% CO2 incubators. Cells were exposed to 20Gy of ionizing radiation using X-ray linear accelerator (Rad Source, Suwanee, GA) at a fixed dose rate of 1.15 Gy/min.Four hours after irradiation, specific antibody against AIM2 was used to pull down AIM2 and the binding DNA lesions, which was then analyzed through ChIP-Seq.

mRNA and lncRNA expression analysis of irradiated and nonirradiated human HaCaT cells

Project description:This study aims to compare mRNA expression between radiated and non-radiated human keratinocyte HaCaT cells by microarray analysis. Human keratinocyte HaCaT cells were divided into two groups, each group has three repeats. The cells were irradiated with a single dose of 0 or 20Gy of X-ray irradiation. 48 hours post radiation, cells from 0 or 20 Gy groups were collected and subjected to microarray analysis. mRNA and lncRNA profilings of each group were analyzed by microarray.

Microarray analysis of rice plants irradiated with carbon ion beams (HIMAC)

Project description:In this study, carbon-ion beams generated via the heavy-ion medical accelerator in Chiba (HIMAC) were targeted to growing rice seedlings (7-days-old) to examine their effect on this genome model. Both physiological parameters, such as growth, and molecular events, specially the gene expression profiles were examined immediately after irradiation (at 270 Gy dose) by rice oligo (22K) DNA microarrays. Genome-wide transcriptional profiling of radiation-response genes in rice provides us with first report on how our radioactive environment affects a plant species. Keywords: Irradiation response

ATAC-seq analysis of radioresistant/sensitive cells in oral cancer

Project description:ATAC-seq identified a total 80,764 peaks in radioresistant cells (HSC-3;0Gy, 8Gy) and radiosensitive cells (KOSC-2;0Gy, 8Gy) (n=2). 1273 peaks were shown as chromatin opened regions and 839 peaks were shown as chromatin closed regions in HSC-3 8Gy compared to HSC-3 0Gy. 285 peaks were shown as chromatin opened regions and 1760 peaks were shown as chromatin closed regions in KOSC-2 8Gy compared to KOSC-2 0Gy. 3804 peaks were shown as chromatin opened regions and 1929 peaks were shown as chromatin closed regions in KOSC-2 0Gy compared to HSC-3 0Gy. By hierarchical clustering analysis and heatmap, the difference of chromatin accessibility in KOSC-2 was lower than HSC-3.

AIM2-responsive genes in colorectal tumor cells

Project description:Absent in Melanoma 2 (AIM2) is a member of the HIN-200 family of hematopoietic, IFN-inducible nuclear proteins associated with infection defense and tumor pathology. Recently, AIM2 was found to act as a DNA sensor in innate immunity. In addition, a high frequency of AIM2-alterations was observed in microsatellite unstable tumors. To elucidate AIM2 function in colorectal tumors, we here addressed AIM2-responsive genes by microarray. Among genes up-regulated by AIM2, there were a number of interferon-stimulated genes (ISGs: IFIT1, IFIT2, IFIT3, IFI6, IRF7, ISG15, HLA-DRA, HLA-DRB, TLR3 and CIITA) as well as genes involved in intercellular adhesion and matrix remodeling. Expression of ISGs correlated with expression of AIM2 in ten different IFN-γ treated colorectal cancer cell lines. Moreover, knock-down of AIM2 resulted in reduced expression of HLA-DRA, HLA-DRB, and CIITA in IFN-γ treated cells. IFN-γ independent induction of HLA-DR genes and their encoded proteins was also demonstrated upon transient induction of AIM2. STAT-signaling was not involved in IFN-γ independent induction of ISGs, arguing against participation of cytokines released in an autocrine manner. Our data indicate that AIM2 mediates IFN-γ dependent and independent induction of several Interferon stimulated genes (ISGs) including genes encoding the MHC II antigens HLA-DRα and β. we used microarray techniques to define genes responsive to AIM2 expression in colorectal tumor cells. HCT116 is a colorectal tumour cell line with no evidence for AIM2 expression which served as background for gene transfection. B8 and D1 were transfected subclones with persisting expression of AIM2. Gene expression of B8 and D1 was compared with that of mock transfected control cells.

Critical role for the DNA receptor AIM2 in stem-cell proliferation and cancer

Project description:Colorectal cancer is a leading cause of cancer-related deaths. Mutations in the innate immune receptor AIM2 are frequently identified in patients with colorectal cancer, but how AIM2 modulates colonic tumorigenesis is unknown. Here, we found that Aim2-deficient mice were hypersusceptible to colonic tumor development. Production of inflammasome-associated cytokines and other inflammatory mediators were largely intact in Aim2-deficient mice, however, intestinal stem cells were prone to uncontrolled proliferation. Aberrant Wnt signaling expanded a population of tumor-initiating stem cells in the absence of AIM2. Susceptibility of Aim2-deficient mice to colorectal tumorigenesis was enhanced by a dysbiotic gut microbiota, which was reduced by reciprocal exchange of gut microbiota with wild-type healthy mice. These findings uncover a synergy between a specific host genetic factor and gut microbiota in determining the susceptibility to colorectal cancer. Therapeutic modulation of AIM2 expression and microbiota has the potential to prevent colorectal cancer. We used microarrays to compare the transcriptome Aim2 deficent mice to wild type mice in colon tumor and colitis samples. Here were 12 mice in total, 3 for each genotype and tissue combination.

Overexpression of AIM2 inhibits metastasis and promotes apoptosis of hepatocellular carcinoma cells

Project description:It was shown that the AIM2 expression was decreased in human HCC tissues compared with the adjacent normal tissues, and the OS rate of HCC patients with higher AIM2 expression was significantly higher compared with the ones with lower AIM2 expression, indicating that the expression level of AIM2 was significantly correlated with clinical stage. Besides, the expression of AIM2 was significantly associated with the AFP expression, but not associated with PD-L1, Ki67, or CD34 expression in HCC. Pathology classification in HCC tissues could be used as an independent prognostic predictor for the patients. Overexpression of AIM2 could significantly inhibit cancer cell migration and promote their apoptosis. Furthermore, notch signaling pathway may be involved in the regulation of AIM2 in the cellular network of HCC cells.

RNA-Seq analysis of cSCC cells followed by siRNA-induced gene knockdown of AIM2.

Project description:Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, and its incidence is increasing globally. Chronic inflammation has been recognized as a risk factor for cSCC and inflammation is a typical feature of the progression of actinic keratosis lesions to invasive and metastatic cSCC. Inflammasomes are important components of the innate immune response involved in onset of inflammation. Inflammasome component AIM2 serves as a sensor for cytoplasmic double-strand DNA, and this way plays a key role in response to bacterial and viral colonization. Activation of inflammasome by cytoplasmic DNA in epidermal keratinocytes can promote the initiation of inflammation in autoimmune and autoinflammatory skin diseases. Whole transcriptome analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=4) and oligonucleotide array-based expression analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=5) revealed overexpression of AIM2 in cSCC cells (GSE66412 and GSE66368, respectively). We wanted to futher study the RNA expression profile of AIM2 knockdown cSCC cells.
