 en Bile acids cycle disruption in patients with nasopharyngeal carcinoma promotes the elevation of interleukin-10 secretion

Background: Unclear pathogenesis existed for nasopharyngeal carcinoma. Aims: to analyze the role of bile acids in the pathogenesis of nasopharyngeal carcinoma.
Methods: 20 healthy volunteers and 20 patients with nasopharyngeal carcinoma were enrolled between January 1st, 2013 and December 31st, 2014. ESI-QTOF-MS analysis of serum was performed to find altered bile acids components. The biological function of changed bile acids was investigated using in vitro experiment.
Results: Compared with healthy volunteers, the level of DCA and GDCA exhibited higher abundance in patients with nasopharyngeal carcinoma (p<0.01). Furthermore, the biological function was investigated for the inhibition of DCA and GDCA towards the secretion of IL-10 by CD4+CD25- T cells. Both DCA and GDCA significantly inhibited the secretion of IL-10 by CD4+CD25- T cells. Furthermore, DCA+GDCA can show stronger inhibition towards the secretion of IL-10 than DCA and GDCA.
Conclusion: The inhibition of IL-10 secretion by elevated DCA and GDCA components in nasopharyngeal carcinoma patients is the inducer for nasopharyngeal carcinoma.
