They found that the α,α-cycloalkyl amino acids, known as cis- or trans-ACBC, caused tumor cells to accumulate more 10B atoms than L-BPA and its short-chain lipid amino acid derivatives in several cell lines (C6, U81, and A172) expressing the L-type amino acid transporter (LAT) (61, 62). The gene discussed is LAT; the disease is neoplasm.
