SLC1A2 and breast cancer: Surprisingly, we found that EAAT2 transcripts were expressed at relatively high levels in all BC types, while EAAT5 transcripts were expressed at reasonable levels in several types of BCs, more specifically, in RB, BC3B, and BC4 (types 3B and 4 OFF cone BCs, respectively) as well as in BC5B and BC5C (types 5B and 5C ON cone BCs, respectively; Fig. 1A).
