Abstract:
Steroid hormone receptors are key mediators in the execution of hormone action through a combination of genomic and non-genomic action. Since their isolation and characterisation in the early 20th Century much of our understanding of the biological actions of steroid hormones are underpinned by their activated receptor activity. Over the past two decades there has been an acceleration of more omics-based research which has resulted in a major uptick in our comprehension of genomic steroid action. However, it is well understood that steroid hormones can induce very rapid signalling events in tandem with their genomic actions wherein they exert their influence through alterations in gene expression. Thus the totality of genomic and non-genomic steroid action occurs in a simultaneous and reciprocal manner and a greater appreciation of whole cell action is required to fully evaluate steroid hormone activity in vivo. In this mini-review we outline the most recent developments in non-genomic steroid action and cytoplasmic steroid hormone receptor biology in endocrine-related cancers with a focus on the 3-keto steroid receptors, in particular the androgen receptor.
Insights
Steroid hormones act through genomic and non-genomic pathways. This review highlights recent advances in non-genomic steroid action and receptor biology, crucial for understanding endocrine cancers.
Area of Science:
- Endocrinology
- Molecular Biology
- Oncology
Background:
- Steroid hormone receptors mediate hormone action via genomic and non-genomic pathways.
- Genomic understanding has advanced with omics research, but non-genomic actions are also critical.
- Steroid hormone actions are simultaneous and reciprocal, requiring a holistic cell-based evaluation.
Purpose of the Study:
- To review recent developments in non-genomic steroid action.
- To discuss cytoplasmic steroid hormone receptor biology in endocrine cancers.
- To focus on 3-keto steroid receptors, especially the androgen receptor.
Main Methods:
- Literature review of recent scientific publications.
- Focus on omics-based research and non-genomic signaling pathways.
- Analysis of cytoplasmic steroid hormone receptor roles.
Main Results:
- Steroid hormones exhibit rapid non-genomic signaling alongside genomic effects.
- Cytoplasmic receptor activity plays a significant role in endocrine-related cancers.
- Androgen receptor (AR) is a key focus within 3-keto steroid receptors.
Conclusions:
- A comprehensive understanding of both genomic and non-genomic steroid actions is essential.
- Non-genomic actions and cytoplasmic receptor dynamics are vital in endocrine cancer biology.
- Further research into these mechanisms, particularly AR, is needed for therapeutic strategies.
