ABSTRACT
Objective:
To evaluate the role of ten-eleven translocation methylcytosine dioxygenase 3 (TET3) in trigeminal ganglion in maxillofacial inflammatory pain in mice.Methods:
Forty SPF healthy male C57BL/6J mice, aged 8-10 weeks, weighing 19-23 g, were divided into 5 groups ( n=8 each) using a random number tablemethod:
control group (group C), inflammatory pain group (group IP), control+ TET3-siRNA group (group C+ siTET3), inflammatory pain+ TET3-siRNA group (group IP+ siTET3) and inflammatory pain+ negative control Scrambled-siRNA group (group IP+ siNC). Normal saline or complete Freund′s adjuvant (CFA) 10 μl was injected into the temporomandibular joint of mice, respectively, and the mechanical paw withdrawal threshold (MWT) was measured at 1, 4, 8 and 12 days after injection (T 1-4). Before injection of normal saline or CFA, 0.75 μl siTET3 or siNC was injected into the trigeminal ganglion and the animals were then sacrificed and trigeminal ganglion was removed at T 2 for determination of the expression of TET3 by Western blot in C+ siTET3, IP+ siTET3 and IP+ siNC groups.Results:
Compared with group C, MWT was significantly decreased at T 1-3 , the expression of TET3 in trigeminal ganglion was up-regulate in group IP ( P<0.05 or 0.01). Compared with IP and IP+ siNC groups, MWT was significantly increased at T 2, 3, and the expression of TET3 in trigeminal ganglion was down-regulate in group IP+ siTET3 ( P<0.05 or 0.01).Conclusion:
TET3 in trigeminal ganglion is involved in the development of maxillofacial inflammatory pain in mice.
