STAM and brain neoplasm: (iii) Signal transducing adaptor molecule (SH3 domain and ITAM motif) 1 (STAM) is conspicuously up-regulated following paraquat exposure (logFC 4..00; P: 1.4e−4; adjusted P: 1.9e−2) and is believed to be involved in cell growth33 and vesicular trafficking34, and is associated with brain neoplasm in the literature.
