In one study, in a human neuroblastoma model (SK‐N‐MC), it was found that PA‐mediated GPR40 signalling increased the expression of amyloid precursor protein (APP) and the catalytic enzyme BACE1, producing Aβ peptide through mTOR/p70S6K1‐mediated HIF‐1α expression and NF‐κB activation.144. Here, APP is linked to neuroblastoma.
