The expression of NUP188 in gastric cancer (GC) was detected by immunohistochemistry. The association between NUP188 and clinicopathologic features was explored, and the predictive value of NUP188 was determined.

The NUP188 expression was associated with molecular subtype, pathologic stage, prognosis, cancer status, and genomic heterogeneity in multiple cancer types. NUP188 was also related to the immune subtype and infiltrating levels of immune cells. The protein level of NUP188 was both upregulated in GC tissues, and was related to HP infection, depth of invasion, distant metastasis, TNM stage, and overall survival of GC patients. NUP188 interference restrained the proliferation, migration, and invasion of GC cells, and inhibited the GC growth <jats:italic>in
