SLC1A3 and astrocytoma (excluding glioblastoma): Transcriptomics analyses indicated that the human breast cancer cell line MDA-MB-468 has a high endogenous expression of EAAT1 (BioSamples database: SAMN11893674, SAMN11893681, SAMN11893688), whereas the human astrocytoma cell line (1321N1) lacked endogenous EAAT1 expression (BioSamples database: SAMN11893671, SAMN11893678, SAMN11893685).
