The expression levels of Gln transporters ASCT2 (SLC1A5), LAT1 (SLC7A5), and ASCT1 (SLC1A4) are dynamically regulated by several oncogenes driving PCa progression, including MYC, androgen receptor (AR), and mTORC1 [107,108,109]. The gene discussed is SLC1A4; the disease is posterior cortical atrophy.
