Expression data from 4T1 cells cultured with 3mM glucose and 20mM lactic acid

ABSTRACT: Via aerobic glycolysis-Warnburg effect, cancer cells can convert 85-90% of glucose they acquire to lactic acid, which is thus ubiquitously abundant in solid tumor environment. We also observed that lactic acid effectively rescues cancer cells from glucose staration. In order to understand the biological function of lacitc acid, we did the microarrays. murine breast cancer 4T1 cells were incubated in RPMI-1640 containing 3mM glucose and 20mM lactic acid for 1 day, 3 days, 4 days, 5 days, 7 days, 9 days and 11 days. 4T1 cells were incubated in RPMI-1640 containing 3mM glucose as control. We extracted the RNA and hybridized on the microarrays. We sought to obtain temporal genes that prolonged the cell life with lactic acid during the glucose starvation.

4T1 breast tumors: SPARC knock down primary tumors vs. Control primary tumors vs. Lung metastasis foci

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

Label-free LC-MS/MS of Ubiquitinated proteins derived from UPs-4T1/WT and UPs-4T1/EPB nanovaccine

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.

Expression data from TKI258 treated 4T1 tumors

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.

Pyroptosis therapy targeting TNBC

Project description:Biomimetic nanococrystals are prepared using the preferred combination of mitoxantrone and gambogic acid for rational drug delivery. The unique mechanism of obtained nanococrystals regulating pyroptosis genes through ribosomal stress is revealed by TMT-proteomics of 4T1 cells.

TGF-beta-mediated microRNA expression in breast cancer cells

Project description:We utilized 3D-organotypic cultures whose physical properties were altered by inclusiong of type I collagen to create biomechanically rigid microenvironments that approximated those typically observed in primary mammary tumors. Compliant 3D-organotypic cultures were also generated to recapitulate the biomechanical properties of pulmonary microenvironments typically encountered by disseminated breast carcioma cells. The murine 4T1 progression series represents an established model of triple negative breast cancer development and metastasis and consists of isogenically-derived nonmetastatic 67NR, systemically invasive 4TO7, and highly metastatic 4T1 cells that were propagated for 6 days in the absense or presense of TGF-beta in either rigid or compliant 3D-cultures. Afterward, total RNA was extracted and subjected to miRNA profiling. two replicates of each growth and treatment condition for each cell line.

Gene expression analysis of 4T1 tumors expressing mouse urokinase plasminogen activitor (uPA)

Project description:Analysis of uPA regulation of 4T1 tumor growth at gene expression level. The hypothesis tested in the present study was that overexpression of uPA in 4T1 tumor influence the tumor growth and metastasis related cell signaling pathway. 4T1 cells were stably transduced by lentiviral vector expressing mouse uPA or empty vector. After day 7 of inoculation of 4T1 cells into fatpad of Balb/c mice. Total RNA was extracted from tumor samples (triplicate) using Qiagen total RNA isolation kit. The Illumina MouseWG-6 v2.0 Expression BeadChip (Illumina, Wallingford, CT) was used for gene expression. The raw data from the fluorescence intensity measurements of each array experiment was processed using GeneSpringGX v.11.0 software (Agilent, Santa Clara, CA). Statistical analysis, fold change calculations, and hierarchical clustering of the data were also performed in GeneSpring software. Genes that expressed significantly differently with more than 1.5-fold change and a p-value of <0.05 with respect to controls were taken into consideration. Gene expression data were further validated by qRT-PCR analysis. Pathway analysis was performed by MetaCore software (GeneGo, Inc, St. Joseph, MI).

Single-cell RNA-sequencing identifies anti-cancer immune phenotypes in the early lung metastatic niche during breast cancer

Project description:This experiment looks at the dissection of the microenvironment in the lung metastatic niche in a model of murine triple-negative breast cancer as disease progresses. Mice received an orthotopic inoculation of 4T1 cells and disease was allowed to progress for 7, 14, or 21 days correlating to the pre-metastatic, micro-metastatic, and metastatic niche, respectively. Healthy controls were obtained along with each time point.

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.
