Interestingly, in both models, invasive gastric carcinomas share expression of the transcriptional regulator gene Etv1 which has recently been shown to encode a master regulator in neuronally derived GIST tumors and is commonly affected by gene translocations in prostate tumors which often exhibit a neuroendocrine phenotype upon progression [18], [24], [25]. This evidence concerns the gene ETV1 and prostate neoplasm.
