Abstract:
Estrogen-signaling pathways are implicated in the development of breast cancer and prostate cancer. Various studies have focused on additional signaling pathways, mediated by estrogen-related receptors (ERRs). ERRs are constitutively active receptors that share a high degree of homology with the classical estrogen receptors (ERs). However, they do not bind to estrogen, while ERs do. ERRs are involved in the development of alternative pathways that lead to the development of cancer and are regarded as potential therapeutic targets for the treatment of breast cancer and prostate cancer that do not respond to conventional therapies. In this review, we first present general structural features of ERRs. Then, we focus on breast cancer and prostate cancer, which are primarily hormone-dependent cancers, and summarizes recent progress in elucidating the involvement of each ERR in these two types of malignancies.
Insights
Estrogen-related receptors (ERRs) are key in hormone-dependent cancers like breast and prostate cancer. Understanding their role offers new therapeutic targets for treatment-resistant malignancies.
Area of Science:
- Endocrinology
- Molecular Biology
- Oncology
Background:
- Estrogen-signaling pathways are crucial in breast and prostate cancer development.
- Estrogen-related receptors (ERRs) represent alternative pathways, distinct from classical estrogen receptors (ERs).
- ERRs are constitutively active and do not bind estrogen, unlike ERs.
Purpose of the Study:
- To review the structural features of ERRs.
- To elucidate the involvement of each ERR in breast and prostate cancer.
- To highlight ERRs as potential therapeutic targets for hormone-dependent cancers.
Main Methods:
- Literature review focusing on structural characteristics of ERRs.
- Analysis of studies investigating ERR roles in breast and prostate cancer.
- Synthesis of current knowledge on ERR involvement in these malignancies.
Main Results:
- ERRs are homologous to ERs but function independently of estrogen.
- ERRs are implicated in alternative oncogenic pathways in breast and prostate cancer.
- Specific roles of individual ERRs in these cancers are being elucidated.
Conclusions:
- ERRs are significant players in hormone-dependent cancers.
- Targeting ERRs may offer novel treatment strategies for refractory breast and prostate cancers.
- Further research into ERR pathways is critical for therapeutic development.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Mitogens and the Cell Cycle
Transducer Mechanism: Enzyme-Linked Receptors
Major types that are helpful drug targets include:
Intracellular Hormone Receptors
Internal Receptors
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
