Effect of Sunitinib treatment withdrawal on Immunodeficient mice bearing MDA-MB231 tumors

ABSTRACT: Immunodeficient RAG1-/- mice bearing MDA-MB231-LUC+ tumors of 50-70 mm3 were daily administrated by gavage with vehicle (containing, 0.5% carboxymethylcellulose, 1.8 % NaCl, 0.4 % Tween-80, 0.9 %. benzyl alcohol, and ultrapure water adjusted to pH 6.0) or sunitinib (40mg/kg/day) for 30 days followed by treatment withdrawal for 3-4 weeks to allow the tumor regrowth until reaching the same volume as that of the vehicle treated group. Mice were sacrificed when tumor reached the volume of 350-400 mm3 and RNAs of two tumors from two different mice treated with sunitinib or vehicle were extracted. One color experiment with 2 experimental conditions: Sunitinib vs Vehicle (n=2), corresponding to a total of 4 samples.

The molecular mechanisms responsible for the failure of antiangiogenic therapies and how tumors adapt to these therapies are unclear. Here, we applied transcriptomic, proteomic, and metabolomic approaches to preclinical models and provide evidence for tumor adaptation to vascular endothelial growth factor blockade through a metabolic shift toward carbohydrate and lipid metabolism in tumors. During sunitinib or sorafenib treatment, tumor growth was inhibited and tumors were hypoxic and glycolytic ...[more]

Development of gene expression profiles for murine breast tumours treated with Sunitinib

Project description:In order to establish a profile of gene expression of tumours treated with sunitinib, 4T1 breast tumours were allowed to establish in Balb/C mice for 1 week. The mice were then treated with 40 mg/kg Sunitinib in PBS and 3.72% DMSO (treatemt group) or PBS-DMSO vehicle alone (no treatment group), daily for the period of the experiment, after which the tumours were resected homogenised and subjected to CD31 microbead separation of endothelial cells and bulk tissue, both of which were subjected to agilent microarray analysis. Treated tumours greater than 250 mm3 (by caliper measurement) after 8 days of treatment were considered resistant to treatment, those smaller than this were considered sensitive to sunitinib treatment. Total RNA was extracted from each tumour sample using the Qiagen miRNAeasy kit, processed into cRNA using the Agilient low input, one colour labelling kit, hybridised onto the 8 x 66k whole mouse genome expression microarrays. Data was normalised in R64 and comparison matrices between treated and untreated endothelum and bulk fractions were constructed. Genes whose expression was significantly altered by sunitinib treatement were taken forward for further analysis.

Expression data from renal cancer xenograft tumor treated with sunitinib or vehicle

Project description:We established 3 types of primary xenograft models (KURC;Kyoto University Renal Cancer-1,2,3) derived from human renal cell carcinoma tissues, and 40 mg/day of sunitinib was orally administered. We performed microarray analysis to compare the gene expression profile of sunitinib-treated primary xenograft tumors (sensitive or resistant status) with that of vehicle-treated.

The class-specific BCR tonic signal modulates lymphomagenesis in a transgenic model of c-myc transgene deregulation.

Project description:c-myc-3'RR mice developed Burkitt like lymphoma (IgM and IgD positive cells). We wished to study lymphomagenesis in mice carrying a modified B cell receptor with a higher level of tonic signal. The c-myc-3'RR transgene was introduced in a background with an IgH mutation that replaces IgM with IgA expression. Lymphoma arising in double mutant animals mostly carried the phenotype of activated cells, often expressing CD43, and in 10% of cases carrying a plasma cell phenotype. BCR tonic signal appears as a direct modulator of B cell malignancy phenotype. Burkitt lymphoma (BL) from 4 c-myc-3'RR mice, anaplastic (ANA) lymphoma from 4 c-myc-3'RR mice, CD43 negative lymphoma from 4 c-myc-IgA mice and CD43 positive lymphoma from 4 c-myc-IgA mice were investigated.

Transcriptoma comparison of mantle cell lymphoma of c-myc-3'RR/Cdk4R24C mice and c-myc-3'RR/p53+/- mice

Project description:Mantle cell lymphoma (MCL) is a B cell malignancy characterized by a monoclonal proliferation of lymphocytes with co-expression of CD5, CD43 but not CD23. We have developed two murine models of MCL-like lymphoma. Breeding Cdk4R24C mice (a knock-in strain that express a Cdk4 protein resistant to inhibition by p16INK4a and other INK4 family members) with c-myc-3’RR transgenic mice (prone to develop aggressive Burkitt lymphoma-like lymphoma) leads in c-myc/Cdk4R24C mice to development of clonal blastoid MCL-like lymphoma. Breeding p53+/- mice with c-myc-3’RR transgenic mice lead to the development of several mature B cell lymphomas including MCL. In this study we compare MCL transcriptomas of c-myc-3'RR/Cdk4R24C mice and c-myc-3'RR/p53+/- mice. B splenocytes from 2 c-myc/Cdk4R24C lymphoma mice and 2 c-myc-3'RR/p53+/- mice were investigated

c-myc-3'RR/p53+/- mice lymphomas

Project description:c-myc-3'RR mice prone to develop Burkitt lymphoma (BL) were crossed with p53+/- mice in order to obtain c-myc-3'RR/p53+/- mice. These mice develop a wider spectrum of lymphoma including BL, mantle cell lymphoma (MCL) and plasma cell lymphoma (PCL). Transcriptoma analysis of these lymphomas is investigated in these arrays. Four different plasma cell lymphoma (PCL1-4), three different mantle cell lymphoma (MCL1-4) and four different Burkitt lymphoma (BL1-4) were compared.

Differentially expressed genes analysis between dihydroberberine, sunitinib and dihydroberberine plus sunitinib.

Project description:To gain insights into the mechanisms of dihydroberberine, sunitinib and dihydroberberine plus sunitinib on inhibition to A549 cells, we have employed whole genome microarray expression profiling as a discovery platform to identify different genes between dihydroberberine, sunitinib and dihydroberberine plus sunitinib-treated sample and control. A549 cells were cultivated in the absence or presence of 25?mol/L dihydroberberine, 2?mol/L sunitinib, 25?mol/L dihydroberberine plus 2?mol/L sunitinib for 48 h, followed by the Agilent Whole Human Genome Oligo Microarray
