[Influence of fluorine on expression of androgen-binding protein and inhibin B mRNA in rat testis sertoli cells].

OBJECTIVE
To study the influence of fluorine on the transcription level of androgen binding protein (ABP) and inhibin B (INHB) mRNA in testis sertoli cells of Sprague Dawley rats.


METHODS
A method was set up the model to culture the Sertoli cells. Use a series of concentrations of NaF solutions of 2.5, 5.0, 10.0 and 20.0 mg/L to poison the cells and then, measure the relative expression amount of ABP and INHB mRNA by RT-PCR method.


RESULTS
(1) Compare the relative expression amount of ABP mRNA of each group of different concentration with the control group. 2.5 mg/L group was higher than that in the control group, and the difference has the statistical significance (P < 0.05). The 5.0 mg/L group was also higher than that of the control group, and the difference has no statistical significance (P > 0.05). (2) Compare the relative expression amount of INH B mRNA of each group of different concentration with the control group. Both the 2.5 mg/L group and the 5.0 mg/L group were higher than that in the control group, and the difference has the statistical significance (P < 0.05). The rest 2 groups were lower than that in the control group and the difference has no statistical significance (P > 0.05).


CONCLUSION
In the range of concentrations between 2.5 and 20.0 mg/L, no distinct influence of fluorine on the expression of androgen binding protein (ABP) and inhibin B (INHB) mRNA in testis sertoli cells of Sprague Dawley rats.
