Microarray analysis of gene expression profiles in human neuroblastoma cells exposed to Amyloid beta-Zn and Amyloid beta-Cu complexes


ABSTRACT: Abnormal metal accumulation is associated with Alzheimer’s disease (AD) and has a relevant role in affecting amyloid beta-peptide (Abeta) aggregation and neurotoxicity.In the present study, employing a microarray analysis of 35,129 genes, we analyzed gene expression profile changes due to exposure to Abeta-Zn or Abeta-Cu complexes in neuronal-like cells (SH-SY5Y). Microarray data indicated that Abeta-Zn or Abeta-Cu complexes selectively alter expression of genes mainly related to cell death, inflammatory responses, and apoptosis.Taken together these findings indicate that Abeta-Zn or Abeta-Cu show some commonalities in affecting AD-related target functions. The overall modulatory activity on these genes supports the idea of a possible net result leading to mechanisms that counteract toxic effects of Abeta-Zn or Abeta-Cu.
