Lipopolysaccharide-mediated protein expression profiling on neuronal differentiated SH-SY5Y cells

Lipopolysaccharide-mediated protein expression profiling on neuronal differentiated SH-SY5Y cells Abstract Neuroinflammation can contribute to neuronal dysfunction, death and several neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and multiple sclerosis. Lipopolysaccharide (LPS)-induced neuroinflammation severely affects neurons and can contribute to neuronal dysfunction and degeneration by causing the release of inflammatory and neurotoxic factors. We evaluated the long-term effects of treating differentiated SH-SY5Y cells with LPS to mimic LPS-induced neuroinflammation. Using matrix assisted laser desorption ionization-time of flight mass spectrometry and MetaCore pathway analysis software (GeneGo), the proteomic expression profiles of differentiated SH-SY 5Y cells after LPS treatment was studied to determine the inflammatory effects on the process of SH-SY5Y differentiation. Long-term LPS treatment resulted in the upregulation of phosphodiesterase 4B (PDE4B), slit robo GTPase (SRGAP2), transcription repressor E2F-6, vimentin, and 70 kDa heat shock protein 9 (Mortalin/HSPA9). Taken together, our results suggest that LPS-treated differentiation of SH-SY5Y cells can lend insight into the multiple pathways involved in neurological diseases. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png BioChip Journal Springer Journals

Abstract

Abstract Neuroinflammation can contribute to neuronal dysfunction, death and several neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and multiple sclerosis. Lipopolysaccharide (LPS)-induced neuroinflammation severely affects neurons and can contribute to neuronal dysfunction and degeneration by causing the release of inflammatory and neurotoxic factors. We evaluated the long-term effects of treating differentiated SH-SY5Y cells with LPS to mimic LPS-induced neuroinflammation. Using matrix assisted laser desorption ionization-time of flight mass spectrometry and MetaCore pathway analysis software (GeneGo), the proteomic expression profiles of differentiated SH-SY 5Y cells after LPS treatment was studied to determine the inflammatory effects on the process of SH-SY5Y differentiation. Long-term LPS treatment resulted in the upregulation of phosphodiesterase 4B (PDE4B), slit robo GTPase (SRGAP2), transcription repressor E2F-6, vimentin, and 70 kDa heat shock protein 9 (Mortalin/HSPA9). Taken together, our results suggest that LPS-treated differentiation of SH-SY5Y cells can lend insight into the multiple pathways involved in neurological diseases.
