Similarly to the higher expression of HSP90AA1 in primary OxPhos-reliant cells, three out of four OxPhos-DLBCL cell lines (K422, Toledo, Ly4) demonstrated significantly increased HSP90AA1 transcript and HSP90α protein levels (relative values greater than the average for all cell lines), whereas among the 4 OxPhos-independent cell lines DHL4, DHL6 and Ly1 showed lower HSP90α gene and protein expression (relative values lower than the average for all cell lines, Supplementary Fig. S1). This evidence concerns the gene HSP90AA1 and diffuse large B-cell lymphoma.
