Abstract:
Oncologists have traditionally considered that tumorigenesis are closely related to classical nuclear estrogen receptors (ERs), such as estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ), through the ligands binding and target gene transcription induction. Estrogen-related receptors (ERRs) have similar structures with ERs, which are also gradually thought to be relevant to reproductive endocrine tumor diseases, even non-reproductive endocrine tumors. In this review, different subtypes of ERRs and their structures firstly will be introduced, then the expression patterns in gynecological oncology (i.e., breast cancer, endometrial cancer, and ovarian cancer), male genitourinary system malignancy especially prostatic cancer along with other non-reproductive endocrine tumors (i.e., lung cancer, colorectal cancer, and liver cancer) will be described, and simultaneously the role of tumorigenesis related to ERRs will be discussed. Therefore, the review is benefit to explore the way of tumor prevention and treatment.
Insights
Estrogen-related receptors (ERRs) are increasingly linked to various cancers, including reproductive and non-reproductive tumors. Understanding ERRs
Area of Science:
- Endocrinology
- Oncology
- Molecular Biology
Background:
- Estrogen receptors (ERs) are traditionally linked to tumorigenesis.
- Estrogen-related receptors (ERRs) share structural similarities with ERs.
- ERRs are emerging as potential factors in both reproductive and non-reproductive endocrine tumors.
Purpose of the Study:
- To introduce different subtypes and structures of ERRs.
- To describe ERRs expression patterns in various cancers.
- To discuss the role of ERRs in tumorigenesis for potential therapeutic strategies.
Main Methods:
- Literature review of ERRs
- Analysis of ERRs expression in gynecological cancers (breast, endometrial, ovarian)
- Examination of ERRs in male genitourinary cancers (prostate) and other tumors (lung, colorectal, liver)
Main Results:
- Detailed introduction to ERRs subtypes and structures.
- Comprehensive overview of ERRs expression across diverse cancer types.
- Discussion on the involvement of ERRs in the processes of tumorigenesis.
Conclusions:
- ERRs are implicated in a wide range of cancers.
- Further research into ERRs may offer novel avenues for cancer prevention and treatment.
- This review provides a foundation for understanding ERRs in oncology.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Endocrine Signaling
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...
