Effect of hIAPP aggregation on gene expression by mouse bone marrow-derived macrophages after 12 hours. Mus musculus

The purpose of this experiment was to determine changes in gene expression by bone marrow-derived macrophages (BMDMs) treated with synthetic human vs. rodent islet amyloid polypeptide (IAPP). Synthetic human IAPP at 15 uM aggregates to form fibrils in vitro, whereas rodent IAPP is non-amyloidogenic. We hypothesized that interaction of macrophages with human IAPP aggregates can activate pro-inflammatory signalling pathways in macrophages, as described for other amyloidogenic peptides. Overall design: This array includes eight samples from one experiment, with two groups of four replicates each. Each replicate represents BMDMs from one well of a 24-well plate. The control group was treated with 15 uM rat IAPP for 12 hours prior to total RNA extraction; the experimental group was treated with 15 uM human IAPP.
