Therefore, the meta isomer of L-BPA, (L)-3-dihydroxy-borylphenylalanine or 3-BPA (3), was recently evaluated in various LAT1-expressing tumor cells (B16F10, T3M-4, U87MG, A549) and in BALB/c mice bearing B16F10 or T3M-4 subcutaneous tumors [16]. The gene discussed is SLC7A5; the disease is neoplasm.
