NKILA is a novel suppressor of local recurrence in women breast malignant phyllodes tumor patients via inhibition of the NF-κB pathway.

ABSTRACT

The aim of the present study was to explore the functional mechanism of NF-Kappa B-interacting Long non-protein coding RNA (NKILA) in breast malignant phyllodes tumors (BMPTs). The expression and functional role of NKILA were investigated by performing qRT‒PCR, Transwell assays, and CCK‒8 assays in primary BMPT cells. A Kaplan‒Meier curve was used to assess overall survival (OS) and local recurrence-free survival (LRFS). The location and expression levels of NKILA and P65 were determined by fluorescence in situ hybridization (FISH) and immunofluorescence (IF), respectively. NKILA was downregulated in patients with BMPT, especially in patients with local recurrence. NKILA had an antitumor effect and promoted the chemosensitivity of cells to cisplatin by blocking P65 phosphorylation and nuclear translocation. In conclusion, NKILA may be a potential therapeutic target for BMPT, especially for BMPT patients with local recurrence.
