As another member of GPRIN family, G protein-regulated inducer of neurite outgrowth 1 (GPRIN1) has prognostic value and exerts biological functions in lung cancer, regulating cell epithelial–mesenchymal transition to promote lung cancer growth and metastasis, which indicates that GPRIN1 may become a useful target for lung cancer treatments [18]. Here, GPRIN1 is linked to lung carcinoma.
