SLCO1B3 and spindle cell hemangioma: The lack of inhibitory effects of bortezomib pretreatment on pitavastatin accumulation mediated by OATP1B1 (Fig 7B) and OATP1B3 (Fig 5D) is consistent with the finding that pretreatment with bortezomib did not affect pitavastatin accumulation in human SCH (Fig 7E).
