Project description:Murine 4T1-T Breast cancer cells were infected with retroviral vectors harboring shRNAs for murine or a Renilla, as negative control. After selection cells were harvested and processed with the NuGen Ovation RNAseq system V2. Libraries were sequenced on an Illumina platform and mapped using Bowtie2 to the mm10 genome prior to transcript quantification using HT-Count.
Project description:Comparative analysis of the transcriptome of 4T1 cells stably transduced with a lentiviral vector expressing a siRNA against murine SPARC (4T1-C18) with 4T1 control cells stably transduced with a lentiviral vector expressing a scramble sequence (4T1-SCR). Two-condition experiment, 4T1-C18 vs. 4T1-SCR cells. Biological replicates: 4 SPARC knock down, 4 control, independently grown in vitro and harvested. One replicate per array. Microarrays were hybridized in three different days.
Project description:Murine 4T1-T breast cancer cells were infected with retroviral vectors harboring shRNAs for murine or a Renilla, as negative control. Cells were orthotopically injected into NSG mice. After 19 days mice were euthanized and tumors and lungs were removed and digested into single cells. Cells were then placed in culture dishes with 6TG. Surviving cells were then harvested and processed with the NuGen Ovation RNAseq system V2. Libraries were sequenced on an Illumina platform and mapped using Bowtie2 to the mm10 genome prior to transcript quantification using HT-Count.

Project description:Comparative analysis of the transcriptome of primary tumors generated from 4T1 cells transduced with a lentiviral vector expressing a siRNA against murine SPARC (4T1-C18), primary tumors generated from 4T1 cells transduced with a lentiviral vector expressing a scramble sequence (4T1-SCR) or lung metastasis foci from 4T1-SCR tumor-bearing mice (4T1-SCR MTTS). Three experimental conditions, 4T1-C18, 4T1-SCR and 4T1-SCR MTTS. Biological replicates: 4 4T1-C18, 4 4T1-SCR, 4 4T1-SCR MTTS independently grown in different mice. 2 days-old tumors and 30 days old lung foci. One replicate per array. All microarrays were processed the same day

Project description:Tumor-associated macrophages (TAMs) are closely related to poor prognosis in triple-negative breast cancer (TNBC). Thus, gaining insight into how TAMs support cancer progression could contribute to effective therapies. We utilized the 4T1 murine TNBC cell line and murine bone marrow-derived macrophages to assess TAMs mediated pro-proliferative effects in vivo and in vitro. Further, Transcriptional analysis was performed to identify pathways activated in TAMs stimulated 4T1 cells. To simulate tumor microenvironment, M2 macrophages and 4T1 cells were plated into upper and lower chambers of Transwell co-culture systems respectively. we performed RNA-sequencing analysis of 4T1 cells incubated with vehicle control or M2 macrophages.
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:LDHA is key enzyme for tumor glycolysis metabolism and knocking down LDHA would change a lot of gene expression We used microarrays to detail the global gene expression in 4T1 cells with LDHA knocked down by shRNA
