PPBP and androgen insensitivity syndrome: Seven differentially expressed proteins were identified: lymphatic vessel endothelial hyaluronic acid receptor-1 (LYVE1), thrombospondin-1 (THBS1), pro-platelet basic protein (PPBP), secreted phosphoprotein-2 (SPP2), insulin-like growth factor-2 (IGF2), cadherin 1 (CDH1), and apolipoprotein C 4-2 (APOC4-APOC2), four of which were elevated (LYVE1, THBS1, PPBP, and IGF2) and subsequently validated by Western blot analysis in patients with AIS caused by LVO versus healthy control subjects.
