Uptake of 3BrPA has been reported to be dependent on the monocarboxylate transporter MCT1, or SLC16A1. The expression of this lactate transporter correlates to a more pronounced glycolytic profile.20 In this study we showed that the levels of SLC16A1 was elevated both in ccRCC tissue samples and in cultured primary ccRCC cells compared with normal kidney cells, suggesting an increased uptake of 3BrPA specifically in ccRCC tumor cells. Here, SLC16A1 is linked to neoplasm.
