That the human NUDT13 gene is subject to regulation has been shown by the direct correlation of its expression with that of the proposed tumor suppressors MFSD4 and occludin (OCLN) and the inverse correlation with that of the metastasis-promoting bone morphogenetic protein 2 (BMP2) in several gastric cancer cell lines [33]. The gene discussed is SLC60A1; the disease is neoplasm.
