The LAMP2 gene encodes three alternatively spliced RNA isoforms, LAMP2A, LAMP2B, and LAMP2C, which are distinguishable by a variable transmembrane domain with a 13‐amino acid cytoplasmic tail.[17] We subsequently generated LAMP2a‐, LAMP2b‐, and LAMP2c‐deficient CRC cells (Figure S5E,F, Supporting Information), and found that aripiprazole significantly inhibited the viability of cells with LAMP2b or LAMP2c deficiency (Figure S5G, Supporting Information), but not LAMP2a deficiency (Figure 3D–F; Figure S5G,H, Supporting Information). This evidence concerns the gene LAMP2 and colorectal carcinoma.
