1.1.2. Membrane Androgen Receptor

Scientific evidence accumulated in recent year’s [sic] points to the existence of membrane androgen receptors (mARs), triggering rapid, non-genomic signals. Although the exact molecular identity of mAR still remains unknown, non-genomic androgen actions manifested within minutes have been reported in various cell types including macrophages and T cells [Benten WP, et al. 1999; Benten WP, et al. 1999], LNCaP [Kampa M, et al. 2002; Wang Z, et al. 2008], T47D [Kampa M, et al. 2005], MCF7 [Kallergi G, et al. 2007], DU145 [Hatzoglou A, et al. 2005; Papadopoulou N, et al. 2008a; Papadopoulou N, et al 2008b], C6 [Gatson JW, et al. 2006], PC12 [Alexaki VI, et al. 2006] or VSMC cells [Somjen D, et al 2004]. These effects are clearly different from those manifested upon activation of the intracellular androgen receptors (iARs) mediating genomic androgen signals resulting in receptor dimerization, nuclear translocation and subsequent activation of androgen-specific target genes.
