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:To better understand how lung neutrophils transcriptionally differ from other tissue neutrophils, we performed single-cell RNA sequencing (scRNA-seq) on BM, PB and lung neutrophils isolated from naïve (BALBc/J) and 4T1 tumor-bearing mice.
Project description:4T1 mouse mammary carcinoma cells have an autocrine FGFR active loop leading to constitutive activation of downstream signaling pathways. We found that FGFR inhibitors have a strong effect on 4T1 tumors in-vivo. We used microarray to understand the contribution of FGFR signaling to the tumor formation upon TKI258 treatment. 4T1 cells were injected in the 4th mammary gland of Balb/C mice. After 7 days, daily treatment with TKI258 or water was performed for 14 days. At the end of the experiment, the RNA were extracted from three individual tumors per condition and hybridized on Affimetrix microarrays.
Project description:This SuperSeries is composed of the following subset Series: GSE19220: Expression data from TKI258 treated 4T1 cells GSE19221: Expression data from TKI258 treated 4T1 tumors Refer to individual Series
