Abstract

Pancreatic adenocarcinoma (PA) is a leading cause of adult cancer mortality, and surgery is still the best available treatment strategy. However, PA can recur at any time and has limited prognosis. It is therefore necessary to explore novel serum biomarkers of PA to allow the early diagnosis of PA. Soluble a‑proliferation‑inducing ligand (sAPRIL), a promising inducer of the epithelial‑mesenchymal transition (EMT), is often found overexpressed in a variety of autoimmune diseases. To determine whether serum sAPRIL can constitute a PA biomarker, the protein level of sAPRIL was examined by immunohistochemistry and western blot, and the mRNA level was quantified by RT‑qPCR. The PA cell line PanC‑1 was transfected with vectors bearing the sAPRIL gene and sAPRIL short hairpin RNA (shRNA) oligos. Increased expression of serum sAPRIL was observed in patients with PA recurrence or metastasis after five‑year surgery compared to subjects without PA recurrence or metastasis. The growth rate of PanC‑1 cells transfected with the sAPRIL expression vector was increased by 23% (P<0.01, vs. control group), and was reduced by 17% (P<0.01, vs. control group) in the sAPRIL shRNA‑silenced cell line. Thus, sAPRIL is highly expressed in PA, and serum levels of sAPRIL can serve as a useful indicator for the recurrence or metastasis of PA after surgery. Additional validation studies on the use of serum sAPRIL as a diagnostic marker in PA are however needed.
