Further, several studies showed that SAMD9L plays an important role in the regulation of cell proliferation as a tumor suppressor.24,25 Furthermore, we constructed a SAMD9L protein interaction network utilizing the Coexpedia (http://www.coexpedia.org/) and STRING (https://string-db.org/) websites, as depicted in Figure 2C and 2D.The results encouraged us to identify the function of the SAMD9L gene in gastric cancer. This evidence concerns the gene SAMD9L and gastric cancer.
