Does bile acids cycle disruption in patients with nasopharyngeal carcinoma promote the elevation of interleukin-10 secretion? Context: Unclear pathogenesis existed for nasopharyngeal carcinoma. to analyze the role of bile acids in the pathogenesis of nasopharyngeal carcinoma. 20 healthy volunteers and 20 patients with nasopharyngeal carcinoma were enrolled between January 1(st), 2013 and December 31(st), 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. 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.

The inhibition of IL-10 secretion by elevated DCA and GDCA components in nasopharyngeal carcinoma patients is the inducer for nasopharyngeal carcinoma. Final Decision: yes
