Project description:Microaaray data for CD44v8-10-positive / CD44v8-10-negative 4T1 cancer cells (mouse breast cancer cells) We used microarrays to detail the global programming of gene expression of 4T1 cells depending on whether CD44v is present or not. 4T1 cells, one of the mouse breast cancer cells, were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the data about to which extent gene expression profile is different between CD44v-positive and CD44v-negative 4T1 cancer cells.

Project description:In this project, 4T1 parental cells (4T1/WT) were exposed to increasing concentrations of epirubicin (EPB) to establish a novel multi-drug resistant CSC-like breast cancer cell line (4T1/EPB). The ubiquitinated proteins were enriched from 4T1/WT or 4T1/EPB derived cell lysate using a-Al2O3-Vx3 nanoparticles to produce the covalently linked product UPs nanovaccine. Label-free LC-MS/MS mass spectrometry was used to detect the type and amount of enriched proteins of UPs from the 4T1/WT cells and the 4T1/EPB cells.

Project description:Novel therapies targeting cancer stem cells (CSCs), which play critical roles in chemo- and radio-resistance, metastasis, and possibly resistance against cancer immunotherapy including granulocyte-macrophage colony-stimulating factor (GM-CSF) gene-transduced tumor cell vaccines, may provide beneficial clinical outcomes. Here, we used syngeneic immunocompetent mice that allowed precise evaluation of the immunogenicity of the side population (SP) isolated from 4T1 murine breast carcinoma (4T1-SP) cells as putative CSCs. 4T1-SP cells showed various stem cell properties including high capacities for colony formation and tumorigenicity as well as high expression of phosphorylated signal transducer and activator of transcription-3 and vascular endothelial growth factor that are inductive of immune tolerance. Despite these progressive malignant characteristics of 4T1-SP cells, subcutaneous injection of non-transmissible Sendai virus-mediated GM-CSF gene-transduced 4T1-SP (4T1-SP/GM) cells remarkably impaired their tumorigenicity compared with that of the controls. This impairment of tumorigenicity was partially dependent on CD8+ T cells in concert with CD4+ T cells and natural killer cells. Notably, therapeutic vaccinations using irradiated 4T1-SP/GM cells markedly suppressed tumor development of subcutaneously transplanted 4T1-SP cells compared with that of the controls including irradiated 4T1-non-SP/GM cells. Tumor suppression was accompanied by robust accumulation of mature dendritic cells at vaccination sites and systemic Th1-based cellular immunity. Moreover, vaccinations comprising primary 4T1-SP cells isolated from transplanted 4T1-SP tumors elicited antitumor effects. cDNA microarray analysis showed that 4T1-SP cells predominantly expressed genes of cancer-related antigens including cancer/testis antigens. Collectively, we demonstrate that SP cell-based vaccinations induce effective antitumor immunity that may improve the efficacy of SP cell-based immunotherapy. Gene expression profiles were compared between sorted 4T1-SP and 4T1-NSP cells.

Project description:4T1 mammary cancer cells exihibit higher proliferation and metastatic ability when cultured in conditioned medium from mesenchymal stem cells . Also, co-implantation with MSCs, 4T1 tumors show higher tumor growth and metastasis. We used microarrays to detail the global programme of gene expression underlying the alteration of cell behaviour RNA was extrated from 4T1 cells cultured in MSC-CM or regular medium as well as 4T1 cells isolated from co-cultured with MSCs. Gene expression of these cell groups was acquired from Affymetrix microarray analysis using mouse 430 2.0 array chip.

Project description:We used 4T1 murine breast cancer cells to establish a syngeneic tumor model and found that liver metastatic cells exhibited serveral biological and molecular characteristic that are distinct from parental 4T1 cells. We used microarrays to analyze 4T1-3R_L cells exhibited several CSC related genes compared to 4T1 cells.

Project description:Recently, cancer immunotherapy has been paid much attention because of its improved efficacy and low frequency of adverse effects. A mouse breast cancer cell line, 4T1, has been known as poorly immunogeneic and highly metastatic cell line. In this study, we have identified a sub cell line of 4T1, designated as 4T1-Sapporo (4T1-S), which could induce a strong immune response against the same line. When 4T1-S was subcutaneously injected, striking enlargement of draining lymph nodes and increase of activated T cells were observed. The strong immune responses could not be observed when 4T1-S was injected to nude mice, indicating that this phenomenon is mediated by T cell response. Identification of 4T1-S characteristics may help to improve immunotherapy against breast cancer. 4T1-A1, 4T1-A2, 4T1-S1, 4T1-S2
