Abstract

Aberrant expression of Neuromedin B (NMB) is associated with the malignant progression of Cancer, such as breast Cancer, lung Cancer and glioma. However, the role of NMB in cervical Cancer remains unclear. The present study found that NMB and its receptor NMBR are aberrantly expressed in cervical Cancer. NMB activates ERK1/2 and NF-κB signaling pathways, which promote the proliferation of cervical Cancer cells and increase the expression of tumor necrosis factor α (TNF-α). The downregulation of NMBR by the specific inhibitor, PD168368, abrogates proliferation and promotes Apoptosis of cervical Cancer cells. In addition, the NMB/NMBR signaling axis mediates the promoting effect of cancer-associated adipocytes on cervical Cancer progression. These findings demonstrate the potential role of NMB/NMBR-regulated ERK1/2 and p65 signaling pathway in cervical Cancer progression, which provide new opportunities to diagnose and treat cervical Cancer.
