Expression of Tex14 in female reproductive tracts. A. The expression of two Tex14 fragments up- and downstream of the SA duplication site was investigated in the ovary, oviduct and uterus of control animals. Tex14 exons 17-19 were slightly expressed in all examined female tissues, but the expression appeared markedly lower than in the testis. Exons 31-43 of Tex14 showed no expression in any of the female reproductive tissues confirming the significantly lower expression of Tex14 in the ovary, oviduct and uterus compared to the testis. B. The quantity of Tex14 exons 17-19 expression in the ovary, oviduct and uterus in comparison to the testis was analysed with qPCR and is presented as percentage of the testis expression. Tex14 expression was significantly (P < 0.001) lower in all examined tissues compared to the testis.
