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 the proliferation and survival of these cells. We used microarray to understand the contribution of FGFR signaling to the tumorigenic phenotype of the 4T1 cells. 4T1 cells were grown in tissue culture and treated with TKI258 or DMSO as vehicle control for 16 hours. The RNA were extracted from three individual dishes per condition and hybridized on Affimetrix microarrays.
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:Cell derived xenografts treated with DMSO, Oxa, APAP or OAP2 were collected and then the total RNA was isolated. After removal of the remaining genomic DNA, mRNA was purified from total RNA using polyT and then fragmented with 10× RNA fragmentation buffer and the RNA-seq library was constructed using Hieff NGS Ultima Dual-mode mRNA Library Prep Kit and was sequenced.

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.
