Microgravity-induced alterations in signal transduction in cells of the immune system
2010
Since decades it is known that the activity of cells of the immune system is severely dysregulated in microgravity, however, the underlying molecular aspects have not been elucidated yet. The identification of gravity-sensitive molecular mechanisms in cells of the immune system is an important and indispensable prerequisite for the development of counteractive measures to prevent or treat disturbed immune cell function of astronauts during long-term space missions. Moreover, their sensitivity to altered gravity renders immune cells an ideal model system to understand if and how gravity on Earth is required for normal mammalian cell function and signal transduction. We investigated the effec…

Abstract 4673A: DAPK-mediated phosphorylation of HSF1 enhances apoptosis level upon TNF in colorectal carcinoma cells
2012
Abstract Objectives: Tumor necrosis factor ≤ (TNF) is an inflammatory cytokine, which is released upon different stimuli, including irradiation. Recently it has been shown, that the Death-associated protein kinase (DAPK) mediates TNF-induced apoptosis in colon cancer cells [1]. Here, we aimed to identify new DAPK binding partners and to characterize the functional role of novel protein interaction complexes during TNF-induced apoptosis in colon cancer cells. Methods/Results: HCT116 colorectal cancer cells were cultured for 6 to 48 hours in either normal or TNF-conditioned medium. For phosphopeptide microarray (PPM) whole cell lysates were incubated on peptide platforms with radioactive-labe…
