Glioma pathogenesis-related protein 1 performs dual functions in tumor cells

Glioma pathogenesis-related protein 1 (GLIPR1) was identified as an oncoprotein in some Cancer types including gliomas, breast cancers, melanoma cancers, and Wilms tumors, but as a tumor suppressor in some Other types of cancers, such as prostate cancers, lung cancers, bladder cancers, and thyroid cancers. In gliomas, GLIPR1 promotes the migration and invasion of glioma cells by interaction with the actin polymerization regulator Neural Wiskott-Aldrich syndrome protein (N-WASP) and then abolishes the negative effects of Heterogeneous nuclear ribonuclear protein K (hnRNPK). In prostate cancers, high levels of GLIPR1 induce Apoptosis and destruction of oncoproteins. In lung cancers, overexpression of GLIPR1 inhibits the growth of lung Cancer cells partially through inhibiting the V-ErbB avian erythroblastic leukemia viral oncogene homolog3 (ErbB3) pathway. However, the mechanisms that GLIPR1 performs its function in Other tumors still remain unclear. The tumor suppressing role of GLIPR1 has been explored to the Cancer treatment. The adenoviral vector-mediated Glipr1 (AdGlipr1) gene therapy and the GLIPR1-transmembrane domain deleted (GLIPR1-ΔTM) protein therapy both showed antitumor activities and stimulated immune response in prostate cancers. Whether GLPIR1 can be used to treat Other tumors is an important topic to be explored. Among which, whether GLPIR1 can be used to treat lung Cancer by atomizing inhalation is the key topic we care about. If it does, this therapy has a wide application prospect and is a great progression in lung Cancer treatment.
