GPR107 and prostate neoplasm: Remarkably, GPR107 overexpression was also corroborated in metastasis from metastatic CRPC (mCRPC) compared to primary prostate tumors using two independent external in silico cohorts of patients obtained from different databases available online (Grasso (Figure 2d) and Varambally (Figure 2e)), while this overexpression was not found in mHSPC samples obtained from Lapointe, Taylor and Tomlins in silico cohorts [26,27,28] (Figure S3).
