Changes in global gene expression indicate disordered autophagy, apoptosis and inflammatory processes and downregulation of cytoskeletal signalling and neuronal development in patients with Niemann–Pick C disease

Changes in gene expression profiles were investigated in 23 patients with Niemann-Pick C1 disease (NPC). cDNA expression microarrays with subsequent validation by qRT-PCR were used. Comparison of NPC to control samples revealed upregulation of genes involved in inflammation (MMP3, THBS4), cytokine signalling (MMP3), extracellular matrix degradation (MMP3, CTSK), autophagy and apoptosis (CTSK, GPNMB, PTGIS), immune response (AKR1C3, RCAN2, PTGIS)...
