background hymenodictyon excelsum is a medicinal plant traditionally used for tumor treatment as it contains phytochemicals of anthraquinone and coumarin class. objectives the aim of the present study was to unfold the therapeutic value of selected phytocompounds of hymenodictyon excelsum in prostate cancer. materials and methods eight phytochemicals were selected based on the literature search...

background and objective: since the advent of mammography screening, ductal carcinoma in situ (dcis) of the breast has been diagnosed increasingly. in contrast to the situation in invasive breast carcinoma, there are only a few reports on androgen receptor (ar) status in dcis and few reports on estrogen (er) and progesterone (pr) receptors. materials and methods: ar expression was examined in 5...

background: androgens play critical role in secondary sexual and male gonads differentiations such as spermatogenesis, via androgen receptor. the human androgen receptor (ar) encoding gene contains two regions with three nucleotide polymorphic repeats (cag and ggn) in the first exon. unlike the cag repeats, the ggn has been less studied because of technical difficulties, so the functional role ...

Prostate cancer is the most common type of diagnosed in men worldwide and second leading cause death after lung cancer. Testosterone dihydrotestosterone (DHT) have been known to play an essential role prostate Androgen receptor (AR) binding ligand allows homodimerization translocation nucleus, which acts as a transcription factor for androgen-responsive genes such PSA (Prostate-specific antigen...

Prostate cancer cells depend on androgens and the androgen receptor (AR) for survival. However, after androgen ablation therapy, tumors relapse to an androgen-refractory state. To determine whether the androgen receptor is critical for proliferation of androgen-refractory prostate cancer cells, we disrupted the activity of the androgen receptor with an antibody and an AR mRNA hammerhead ribozym...

Visceral metastasis is widely considered a prognostic factor for overall survival of men with metastatic castration-sensitive prostate cancer (mCSPC) and has been historically managed androgen deprivation therapy (ADT). More recently, this therapeutic scenario enriched by the possibility to integrate ADT chemotherapy or novel androgen-signaling–targeted inhibitors. In order define effect chemot...

Hair follicle cyclical regeneration is regulated by epithelial-mesenchymal interactions. During androgenetic alopecia (AGA), hair stem cells (HFSC) differentiation impaired deregulation of dermal papilla (DPC) secreted factors. We analyzed androgen influence on BMPs expression in DPC and their effect HFSC to lineage. Androgens downregulated BMP2 BMP4 spheroids. Addition restored alkaline phosph...
