Project description:Ki-ras gene mutations are involved in the carcinogenesis of acute myeloid leukemia, melanoma and different carcinomas. In order to define potential mutation-specific therapeutic targets, expression profiling analyses were performed using stable transfected NIH3T3 cells carrying different ki-ras gene mutations. Maybe, this analysis allows the discorvery of ras-associated cellular mechanisms, which might lead to the identification of physiological targets for pharmacological interventions of the treatment of Ki-ras-associated human tumors. Keywords: cDNA microarray, murine fibroblast, ki-ras mutations, carcinogenesis 4 transfected murine fibroblast cell lines (mock, wt-kras, Asp, Val) were compared to non-transfected cell line. For each of the four comparison 4 chip experiments were performed including 2 dye swaps.

Project description:The importance of unanchored Ub in innate immunity has been shown only for a limited number of unanchored Ub-interactors. We investigated what additional cellular factors interact with unanchored Ub and whether unanchored Ub plays a broader role in innate immunity. To identify unanchored Ub-interacting factors from murine lungs, we used His-tagged recombinant poly-Ub chains as bait. These chains were mixed with lung tissue lysates and protein complexes were isolated with Ni-NTA beads. Sample elutions were subjected to mass spectrometry (LC-MSMS) analysis.
