Abstract:
The orphan nuclear receptors (ONRs) are a vital class of transcriptional regulators belonging to the larger nuclear receptors (NRs) superfamily in higher eukaryotes. As a result of non-identification of endogenous physiological ligands for this class of NRs, they are designated as "orphans". The ONRs on receiving appropriate signals translate into specific gene regulation. Elaborate studies on the ONRs in the past two decades have revealed crucial biological functions controlled by them relating to general metabolism, immunity, organogenesis, angiogenesis, growth and development, and numerous other tissue physiologies. Over the years, many of the ONRs have been studied for their participatory role in human health and disease. Results obtained are encouraging and interesting and shows a number of ONRs does modulate several patho-physiological conditions such as cancer and diabetes. This review discusses the current status about the interplay between select ONRs in cancer and diabetes.
Insights
Orphan nuclear receptors (ONRs) regulate gene expression and are crucial for metabolism and development. This review explores their role in modulating cancer and diabetes.
Area of Science:
- Molecular Biology
- Endocrinology
- Genetics
Background:
- Orphan nuclear receptors (ONRs) are a class of nuclear receptors (NRs) lacking identified endogenous ligands.
- ONRs play critical roles in diverse physiological processes including metabolism, immunity, and development.
- Dysregulation of ONRs is implicated in various human diseases.
Purpose of the Study:
- To review the current understanding of the interplay between select ONRs and the patho-physiological conditions of cancer and diabetes.
- To highlight the potential of ONRs as therapeutic targets for these diseases.
Main Methods:
- Literature review of studies on orphan nuclear receptors.
- Analysis of research linking ONRs to cancer and diabetes pathogenesis.
- Synthesis of current findings on ONR function in disease.
Main Results:
- Several ONRs have been identified to modulate key pathways involved in cancer development and progression.
- Specific ONRs play significant roles in regulating glucose metabolism and insulin signaling, relevant to diabetes.
- The interplay between ONRs and these diseases is complex, involving intricate regulatory networks.
Conclusions:
- Orphan nuclear receptors are critical regulators with significant implications in cancer and diabetes.
- Targeting specific ONRs holds promise for novel therapeutic strategies for these prevalent diseases.
