Project description:Ex vivo colorectal adenocarcinoma samples were analysed by desorption electrospray ionisation using an Orbitrap mass spectrometer. The samples were analysed in negative mode over the m/z range 600-1000. Some of the samples presented in this dataset were analysed as part of [1]. The study makes available imzML files of profile and centroid mode data, as well as low- and high- resolution optical image files of H&E-stained sections. These files can be found in the zip file named after each tissue section. </p> Ref:</br> [1] Gerbig S, Golf O, Balog J, Denes J, Baranyai Z, Zarand A, Raso E, Timar J, Takats Z.

Project description:Fungal effectors play important roles in inciting disease development on host plants. We identified an effector (Secreted in Xylem4, SIX4) in an Arabidopsis infecting isolate (Fo5176) of the root-infecting fungal pathogen Fusarium oxysporum and demonstrated this effector is required for full virulence. To explore the role of Fo5176_SIX4 we use whole transcriptome profiling of root tissues from plants overexpressing this effector (35sSIX4) versus wild-type (Col-0) plants after F. oxysporum infection.

Project description:Taking the advantage that B16F10 cells retain the wild-type p53, we introduced the p53 partner into these cells, the p19Arf. Also, in order to induce a immune stimulation in experiments *in vivo*, we introduced the interferon-beta cDNA. This combination induced several benefits when compared to the use of these factors alone, as seen by propidium iodide staining, tunel staining, several gene expression analysis, tumor growth, mice survival, among others. Because of this, we had the interest to study the effects of the combination of p19Arf plus interferon-beta upon gene regulation of B16F10 cells, compared to the effects of these transgenes alone. Previous works from our group that show several benefits of p19Arf plus interferon-beta combination upon B16F10 cells are described in Merkel et al (2010) doi: 10.1186/1471-2407-10-316, Merkel et al (2013) doi:10.1038/cgt.2013.23 and Medrano et al (2016) doi: 10.1007/s00262-016-1807-8 .
Project description:Dysfunction of astrocytic support for prolonged time can be harmful for nervous system. Inflammation and glia activation are among hallmarks of most neurodegenerative diseases. Therefore, astrocytes are considered as druggable targets for disease modifying strategies. Partial lesion of dopaminergic neurons is compensated functionally, but which mechanisms within each type of cells are responsible is unknown. The aim was to check how neuron vs astrocyte degeneration affected remaining astrocytes proteome and which mechanisms were regulated. In a rat model of 7-day infusion by osmotic minipumps of fluorocitrate (FC) into the substantia nigra (SN) (doi: 10.1007/s12035-017-0529-z; doi: 10.1111/jnc.14605; doi: 10.1016/j.mito.2018.12.002) astrocytes become dysfunctional and die inducing activation of remaining astrocytes and microglia. 6-OHDA injected into medial forebrain bundle caused selective degeneration of dopaminergic neurons in the SN. Controls were sham operated. Astrocytes were sorted out from dissociated SN tissue using FACS, and processed for mass spectrometry proteome analysis. Understanding the role of individual cell type in the diseased tissue cellular context is essential to understand disease pathomechanisms and identify better pharmacological targets.

Project description:Nervous system inflammation and microglia activation are among hallmarks of Parkinson’s disease. Partial nigrostriatal neurodegeneration can be compensated. Interaction between neurons, microglia and astrocytes could be essential for this functional adaptation and neuronal survival in long-term, but which mechanisms are responsible is unknown. The aim was to check how astrocyte vs neuron degeneration affected differentially microglia activation proteome and which mechanisms were regulated. In a rat model of 7-day infusion by osmotic minipumps of fluorocitrate (FC) into the substantia nigra (SN) (doi: 10.1007/s12035-017-0529-z; doi: 10.1111/jnc.14605; doi: 10.1016/j.mito.2018.12.002) astrocytes become dysfunctional and die, strongly activating microglia in the process. 6-OHDA injected into medial forebrain bundle caused selective degeneration of dopaminergic neurons in the SN and only slightly activated microglia, probably via different mechanism. Controls were sham operated. Microglia cells were sorted out from dissociated SN tissue using FACS, and processed for mass spectrometry proteome analysis. Microglial response to dying astrocytes vs dying neurons was different. Understanding the role of individual cell type in the diseased tissue cellular context is essential to understand disease pathomechanisms and identify better pharmacological targets.
