A global transcription analysis reveals downregulation of SLC6A14 and an enhanced expression of miR-23b-3p in endocrine therapy resistant breast cancers, what correlates with a prosurvival autophagy and a selective upregulation of SLC1A2 and results in an increased uptake of Glu and Asp (Bacci et al., 2019). Here, SLC6A14 is linked to breast carcinoma.
