Although solenopsin A recruits PTEN to lipid rafts (Additional file 1: Figure S3), it does not appear to be enough to dephosphorylate Akt (Additional file 1: Figure S4) in the human melanoma cell lines A375 and A2058 (both are wild type p53) like it did in 786-O renal cell carcinoma cells (mutant p53) [1]. This evidence concerns the gene TP53 and melanoma.
