Project description:Shotgun proteomics using LC-high resolution tandem mass spectrometry was applied to check the protein expression profiles of C2C12 myotubes in control group (treated with solvent control 0.1% DMSO), C26 medium group (treated with conditioned medium of C26 tumor cells for 48 h), CS group (treated with car-nosol at 20 μM for 48 h) and C26+CS group (treated with conditioned medium of C26 tumor cells in the presence of 20 μM carnosol for 48 h). Samples of three independent experiments were collected.

Project description:We surveyed the transcriptomes of the whole heart and whole gastrocnemius muscle taken from two different types of Balb/c-DBAj hybrid mice (10-11 weeks old). The colon cancer bearing mice are called C26. The NTB are the non-tumor bearing mice. This dataset includes Affymetrix expression data collected from the biological triplicates of heart and gastrocnemius from both C26 and NTB mice.

Project description:Cachexia is an exacerbating event in many types of cancer that is strongly associated with a poor prognosis. We have identified cytokine, signaling and transcription factors that are required for cachexia in the mouse C26 colon carcinoma model of cancer. C2C12 myotubes treated with conditioned medium from C26 cancer cells induced atrophy and activated a STAT-dependent reporter gene but not reporter genes dependent on SMAD, FOXO, C/EBP, NF-ĸB, or AP-1. Of the gp130 family members IL-11, IL-6, oncostatin M (OSM), and leukemia inhibitory factor (LIF), only OSM and LIF were sufficient to activate the STAT reporter in myotubes. A LIF blocking antibody abolished C26 CM-induced STAT reporter activation STAT3 phosphorylation and myotube atrophy, but blocking antibodies to IL-6 or OSM did not. JAK2 inhibitors also blocked the C26 CM-induced STAT reporter activation, STAT3 phosphorylation, and atrophy in myotubes. LIF at levels found in the C26 CM was sufficient for STAT reporter activation and atrophy in myotubes. In vivo, an increase in serum LIF preceded the increase in IL-6 in mice with C26 tumors. Overexpression of a dominant negative Stat3Cβ-EGFP gene in myotubes and in mouse muscle blocked the atrophy caused by C26 CM or C26 tumors, respectively. Taken together these data support an important role of LIF- JAK2-STAT3 in C26 cachexia and point to a therapeutic approach for at least some types of cancer cachexia. from three replicate wells of cells at each treatment, pools of total RNA were used to create cDNA which were evaluated on Affymetrix mouse gene 1.0 ST v.1 arrays.

Project description:Cancer cachexia is a metabolic multifactorial syndrome that causes up to 20% of cancer-related deaths. Muscle atrophy, the hallmark of cancer cachexia, strongly impairs the quality of life of cancer patients; however, the underlying pathological process is still poorly understood. In our study, the transcriptome of cachectic gastrocnemius muscle in the C26 xenograft model was comparied with normal control. The key pathways involving this diseases was discovered according to the different expressed genes.

Project description:Transcriptional profiling of COLO 320 xenograft tumor cells comparing control COLO 320 xenograft without co-implanted rat MSCs with COLO 320 xenograft with co-implanted rat MSCs. The latter makes co-implanted MSCs visualization possible by using MSCs labeled by GFP under FACS and single cell microscopy. Two-condition experiment, COLO 320 xenograft without rat MSCs [COLO320 MSC(-)] vs. COLO 320 xenograft with rat MSCs [COLO320 MSC(+)]. Biological replicates: 1 control, 1 sample, paired xengraft tumor cells grown and harvested from the same mouse host. One replicate per array.

Project description:The application of ketogenic diet (KD) (high fat/low carbohydrate/adequate protein) as an auxiliary cancer therapy is a field of growing attention. KD provides sufficient energy supply for healthy cells, while possibly impairing energy production in highly glycolytic tumor cells. Moreover, KD regulates insulin and tumor related growth factors (like insulin growth factor-1, IGF-1). In order to provide molecular evidence for the proposed additional inhibition of tumor growth when combining chemotherapy with KD, we applied untargeted quantitative metabolome analysis on a spontaneous breast cancer xenograft mouse model, using MDA-MB-468 cells. Healthy mice and mice bearing breast cancer xenografts and receiving cyclophosphamide chemotherapy were compared after treatment with control diet and KD. Metabolomic profiling was performed on plasma samples, applying high-performance liquid chromatography coupled to tandem mass spectrometry. Statistical analysis revealed metabolic fingerprints comprising numerous significantly regulated features in the group of mice bearing breast cancer. This fingerprint disappeared after treatment with KD, resulting in recovery to the metabolic status observed in healthy mice receiving control diet. Moreover, amino acid metabolism as well as fatty acid transport were found to be affected by both the tumor and the applied KD. Our results provide clear evidence of a significant molecular effect of adjuvant KD in the context of tumor growth inhibition and suggest additional mechanisms of tumor suppression beyond the proposed constrain in energy supply of tumor cells.
