D40 mRNA expression was observed in the testes of the patients with OA, HS, MA and Aged, but not in those of the patients with SCO or KL (Fig.?1). We evaluated http://www.selleckchem.com/products/rxdx-106-cep-40783.html the levels of D40 mRNA expression in the testes of infertile men by quantitative RT�CPCR. The D40 mRNA expression levels were normalized to those of 28S rRNA and expressed as D40 mRNA/28S rRNA ratios. Significantly lower D40 mRNA expression was observed in the patients with HS and MA than in those with OA (Fig.?2). It was suspected that the number of germ cells correlated with the expression of D40 mRNA. To assess whether the D40 mRNA level was correlated with clinicopathological findings, we examined the correlations between D40 mRNA and serum FSH, LH, testosterone levels and the Johnsen's score. Serum LH and testosterone levels were not significantly correlated with the D40 mRNA level (data not shown). However, the D40 mRNA/28S rRNA ratio was significantly correlated with the serum FSH level (r?=??0.42, P? https://en.wikipedia.org/wiki/Crotamiton P? http://www.selleckchem.com/products/CP-673451.html showed that D40 mRNA expression was significantly decreased in the infertile men and that the expression levels of both D40 mRNA and protein were correlated with the histopathological degree of germ cell maturation, the serum FSH levels and the Johnsen's score. The amount of D40 protein with a molecular weight of 300?kDa also showed significant correlation with the serum FSH level and Johnsen's score, whereas the amount of the 250?kDa D40 protein was not significantly related to them. This might have been due to the fact that the amount of 250?kDa protein was much smaller than that of 300?kDa. We have previously reported the intracellular localization of D40 protein in the testes in a histoimmunological study.7 An anti-D40 antibody significantly stained the nuclei of spermatocytes and strongly stained the pre-acrosomal regions of round spermatids and the acrosomes of spermatozoa. The findings in the present study that the levels of D40 mRNA and protein in patients with HS were reduced conform to the fact that spermatocytes, round spermatids and spermatozoa were decreased in number in the testes of these patients.
