Abstract
The Androgen receptor (AR) is known to manifest the biological actions of male sex hormones. Androgens are now known to exert a multitude of responses, sometimes contrasting, in physiological and pathological conditions. Several groups have attempted to explain the underlying mechanisms of these varying androgen responses, including the non-genomic actions of androgens. These actions lead to increased activity of pro-proliferative signal transduction pathways, resulting in rapid molecular effects that cannot be explained by the conventional model in which AR functions as a transcription factor to modulate target gene expression [1,2].
This spotlight article examines Safi et al.'s research on the androgen receptor (AR) in prostate cancer, revealing that low androgen levels drive proliferation via non-genomic mechanisms involving AR monomers, while high levels suppress growth through genomic actions with AR dimers. These findings challenge current paradigms and suggest novel therapeutic strategies targeting both AR forms, particularly focusing on the role of AR monomers in cancer progression and treatment resistance.
众所周知,雄性激素受体(AR)能体现雄性激素的生物作用。目前已知雄激素在生理和病理条件下可产生多种反应,有时甚至是截然相反的反应。一些研究小组试图解释这些不同雄激素反应的内在机制,包括雄激素的非基因作用。这些作用导致促增殖信号转导通路的活性增加,从而产生快速的分子效应,而这些效应无法用传统模式来解释,即 AR 作为转录因子调节靶基因的表达[1,2]。这篇聚焦文章探讨了 Safi 等人对前列腺癌中雄激素受体(AR)的研究,揭示了低雄激素水平通过涉及 AR 单体的非基因组机制来推动增殖,而高雄激素水平则通过 AR 二聚体的基因组作用来抑制生长。这些发现对目前的范式提出了挑战,并提出了针对这两种形式的AR的新型治疗策略,尤其关注AR单体在癌症进展和治疗耐药性中的作用。
