The incidence of reproductive disorders is constantly increasing and affects 15% couples, with male's abnormalities diagnosed in almost half the cases. male gonads exert two major functions testis productions gametes (exocrine function) sexual hormones (endocrine function). In last decades, next to steroid receptors such as estrogen androgen receptors, involvement other members nuclear receptor...

Our previous report showed that methylseleninic acid (MSA) significantly decreases the expression of androgen receptor and prostate-specific antigen (PSA) in LNCaP cells. The present study extended the above observations by showing the universality of this phenomenon and that the inhibitory effect of MSA on prostate cancer cell growth and cancer-specific biomarkers is mediated through androgen ...

The partial androgen insensitivity syndrome occurs in 46,XY subjects with phenotypes ranging from perineoscrotal hypospadias with cryptorchidism and micropenis (mild undervirilisation) to clitoromegaly and partial labial fusion (marked undervirilisation). Within an affected family, wide variation in the degree of genital ambiguity between individuals can be seen. Two cousins of a previously rep...

The present work focused on the potential involvement of selective adaptations of the androgen receptor pathway in the initiation and progression of prostate cancer. We defined the androgen receptor pathway by selecting 200 genes that were androgen responsive in prostate cancer cell lines and/or xenografts. This androgen receptor pathway gene signature was then used for profiling prostate cance...

The androgen receptor is encoded by a single-copy gene located in the long arm of the X chromosome (Xq11-12); it consists of eight exons and encodes an intracellular transcription factor that belongs to the steroid/nuclear receptor superfamily. Disturbances in the function of the androgen receptor can lead to several forms of male pseudohermaphroditism, such as androgen insensitivity syndrome, ...

Androgens are presumed to influence gene transcription by modifying the association of the androgen receptor with specific nuclear sites. However, the details of this process are still obscure. Elucidation of the mechanisms involved is complicated by the diversity of androgen binding within targetcell nuclei and by a lack of understanding of the interaction o f androgen receptors with androgen-...

Mutations in the androgen receptor gene in 46,XY individuals can be associated with the androgen insensitivity syndrome, of which the phenotype can vary from a female phenotype to an undervirilized or infertile male phenotype. We have studied the androgen receptor gene of androgen insensitivity patients to get information about amino acid residues or regions involved in DNA binding and transcri...

Little is known about the molecular mechanisms of androgen regulation of the FSHbeta gene; however, studies suggest that it consists of a complex feedback loop that involves multiple mechanisms acting at both the level of the hypothalamus and the pituitary. In the present study, we address androgen regulation of the FSHbeta gene in immortalized gonadotrope cells and investigate the roles of act...

Purpose:Androgen receptor is an essential transcriptional factor that contributes to the development and progressionof prostate cancer. In this study,we investigated the androgen regulation and functional analysis of 14-3-3z in prostate cancer. Experimental Design:Using chromatin immunoprecipitation (ChIP) combined with DNAmicroarray (ChIP-chip) analysis in LNCaP cells, we identified a function...
