AGFG1 and lung carcinoma: Although this miRNA is not described in the literature associated with GC, the miRDB database (database for functional targets of miRNA) points to hsa-miR-3945 as a target of proteins of the Rab family, which is considered a potential indicator of metastasis and prognosis for lung carcinoma [15]; in addition, hsa-miR-3945 is also a target of the TNF receptor protein family that acts in the process of cell proliferation and tumorigenesis [16,17].
