Over the past 20 years, the documented increase in the disorders of male sexual differentiation, such as hypospadias, cryptorchidism, and micropenis, has led to the suspicion that environmental chemicals are detrimental to normal male genital development in utero. Male sexual differentiation is critically dependent on the normal action of androgens, and unbalanced androgen/estrogen ratios can d...
Apoptosis and inhibition of mitosis are primary mechanisms mediating androgen ablation therapy-induced regression of prostate cancer (PCa). However, PCa readily becomes androgen independent, leading to fatal disease. Up-regulated growth and survival signaling is implicated in development of resistance to androgen ablation therapy. We are testing the hypothesis that insulin-like growth factor (I...
Abstract SARS-CoV-2 attacks various organs, most destructively the lung, and cellular entry requires two host cell surface proteins: ACE2 TMPRSS2. Downregulation of one or both these is thus a potential therapeutic approach for COVID-19. TMPRSS2 known target androgen receptor, ligand-activated transcription factor; receptor activation increases levels in tissues, notably prostate. We show here ...
Human activity recognition (HAR) is an emerging research topic in pattern recognition, especially in computer vision. The main objective of human activity recognition is to automatically detect and analyze human activities from the information acquired from different sensors. Human activity prediction using big data remains a challengingly open problem. Several approaches have recently been dev...
We have established highly sensitive and specific androgen and estrogen reporter cell lines which we have named AR (androgen receptor) and ERalpha (estrogen receptor alpha) CALUX (Chemically Activated LUciferase eXpression), respectively. Both bioassays are member of a panel of CALUX reporter cell lines derived from the human U2-OS osteosarcoma cell line, all using highly selective reporter con...
Alteration of androgen receptor function due to hormonally active compounds in the environment, may be responsible for impaired reproductive function in aquatic wildlife. Based on human prostate carcinoma 22RV1 cells, a cell culture expression system was established to test effects of putative androgenic/antiandrogenic compounds on endogenous gene expression. 22RV1 cells were shown to express h...
AIM To investigate the expression of androgen receptors in the extragenital tissues of developing human embryo. METHODS Using immunohistochemistry, we investigated the distribution of androgen receptor (AR) in the extragenital tissues of paraffin-embedded tissue sections of first trimester (8-12 weeks gestation) human embryos. Gender was determined by polymerized chain reaction. RESULTS The...
The estrogen receptor-related receptor alpha (ERRalpha) is an orphan member of the nuclear receptor superfamily that has been shown to interfere with the estrogen-signaling pathway. In this report, we demonstrate that ERRalpha also cross-talks with signaling driven by other steroid hormones. Treatment of human prostatic cells with a specific ERRalpha inverse agonist reduces the expression of se...
Proliferation of LNCaP 104-S cells, a clonal subline of the human prostate cancer cell line, was very slow in androgen-depleted medium but increased 10-13-fold in the presence of 0.1 nM of a synthetic androgen, R1881. This induction of proliferation was diminished at higher concentrations of R1881, indicating the biphasic nature of the androgen effect. After 20-30 passages in androgen-depleted ...
Androgen deprivation therapy (ADT) is a mainstay of prostate cancer treatment, given the dependence cells on androgen and receptor (AR). However, tumors become ADT-resistant, there need to understand mechanism. One possible mechanism upregulation AR co-regulators, although only handful have been definitively linked disease. We previously identified Mediator subunit MED19 as an co-regulator, rep...
