Accumulating reports reveal that serving as an oncogenic factor LAMTOR5 is involved in the progression of many specific cancers. Glucose transporter 1 (GLUT1) is frequently identified in many cancers. However, it remains unexplored whether GLUT1 plays a role in LAMTOR5-enhanced liver cancer. Here, we aim to decipher the function of LAMTOR5 in the regulation of GLUT1 in liver cancer.
