Comprehensive pan-cancer evaluation of NUP85 prognosis, immune infiltration response, and validation in prostate cancer.

backgroundAlthough NUP85 is a member of the nuclear pore complex (NPC) and is associated with chromosome variation and tumor regulation, its specific role in cancer development remains unclear and requires further research.

methodsThis study analyzes the mRNA and protein levels of NUP85 in normal and tumor tissues using the TCGA, GTEx, and HPA databases. We investigated the relationship between NUP85 and survival rates, as well as clinical features, in various tumors by analyzing the TCGA database. The expression pattern of NUP85 in cancer cells is analyzed using single-cell sequencing data from the TISCH database. Two types of prostate cancer cell lines are utilized to investigate the impact of NUP85 on cell proliferation, migration, invasion, and apoptosis, as well as its regulatory mechanism. These analyses aim to uncover the role of NUP85 in cancer, particularly in prostate cancer.

resultsNUP85 is observed to exhibit elevated expression levels across multiple malignancies, with its heightened expression showing consistent associations with poorer clinical prognoses. Bioinformatic analyses further reveal that NUP85 expression patterns demonstrate significant correlations with the activity of cancer-related pathways and immunological interactions involving macrophages and T cell populations. Notably, experimental studies using prostate cancer models have documented reduced cellular proliferation following NUP85 knockout, suggesting a potential functional connection warranting further mechanistic investigation.

conclusionsThe results indicate that elevated NUP85 expression shows strong correlations with cancer initiation and progression. These findings support its potential utility as a candidate biomarker for disease monitoring across various malignancies, though mechanistic validation remains necessary to establish clinical applicability.
