Application

Testosterone 3-(O-carboxymethyl)oxime: BSA-FITC has been used for flow cytometric assays in serum-free cell cultures2. It has also been used for fluorescence labeling experiments in L6 cells3.

Biochem/physiol Actions

Studies have reported that BSA-coupled testosterone can block the growth of LNCaP cells. Furthermore, it can activate Fas protein and cell death, as well as reduce the translocation, adhesion and incursion of iAR-negative, DU145 prostate cancer cells2.

Androgens are known to modulate the skeletal muscle proliferation and differentiation processes. Recent in vitro studies have shown that dihydrotestosterone and anabolic steroids have functions in promoting the proliferation and differentiation of the mouse skeletal muscle myoblast C2C12 cell line

Nongenomic androgen actions imply mechanisms different from the classical intracellular androgen receptor (iAR) activation. We have recently reported the identification of a membrane androgen receptor (mAR) on LNCaP human prostate cancer cells, mediating testosterone signal transduction within minutes. In the

The non-genomic actions of androgen-induced synaptic plasticity have been extensively studied. However, the underlying mechanisms remain controversial. We recently found that testosterone-fetal bovine serum albumin (T-BSA), a cell membrane-impermeable complex, led to a rapid increase in the postsynaptic density 95

Testosterone (T), the principal androgen, and its metabolite, dihydrotestosterone (DHT), are known to mediate their effects through binding to intracellular androgen receptors (iARs). In addition to their well-known genomic effects, androgens rapidly alter neuronal excitability through a non-genomic pathway mediated
