Project description:IL-12 has been considered to be an ideal cytokine for cancer immunotherapy as it can activate both immune and adaptive immune systems. However, in clinical trials, severe side effects were observed in patients with IL-12 systemic administrations. In this study, we generated pH-sensitive polymeric micelle encapsulating IL-12 and compared anti-tumor activities of free IL-12, IL-12 micelle and combination of anti-PD-1 and IL-12 micelle.
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
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: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:The goal is to identify an IL-22Fc specific gene signature in human intestinal epithelial cells in order to support PD biomarkers for IL-22Fc. We have identified IL-22Fc specific activity in HT-29 cells as secreted acute phase proteins only in the presence of IL-1β. Therefore, HT-29 cells (from gCell) will be cultured with IL-22, IL-1β, IL-6 (as a pSTAT3 activation control) as well as IL-22 + IL-1β and IL-6 + IL-1β. The "SAMID" sample characteristic is a sample identifier internal to Genentech. The ID of this project in Genentech's ExpressionPlot database is PRJ0027983 Keywords: Expression profiling by array

Project description:In this study, we examined the differential RNA profile of LY500307 plus PD-1-treated 4T1 cells and PD-1-treated 4T1 cells compared with control 4T1 cells
Project description:Molecular comparison between control 4T1 cells with MMP3-low 4T1 cells RNA extracted from biological triplicates of each of the above mentioned cell populations were subjected to microarray analysis
