Abstract:
The dopamine receptors (DRs) family includes 5 members with differences in signal transduction and ligand affinity. Abnormal DRs expression has been correlated multiple tumors with their clinical outcome. Thus, it has been proposed that DRs-targeting drugs-developed for other diseases as schizophrenia or Parkinson's disease-could be helpful in managing neoplastic diseases. In this review, we discuss the role of DRs and the effects of DRs-targeting in tumor progression and cancer cell biology using multiple high-prevalence neoplasms as examples. The evidence shows that DRs are valid therapeutic targets for certain receptor/disease combinations, but the data are inconclusive or contradictory for others. In either case, further studies are required to define the precise role of DRs in tumor progression and propose better therapeutic strategies for their targeting.
Insights
Dopamine receptors (DRs) show altered expression in many tumors. Targeting DRs may offer new cancer treatments, but more research is needed to confirm their effectiveness and guide therapeutic strategies.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Dopamine receptors (DRs) are implicated in various cellular functions.
- Aberrant DRs expression is linked to tumor development and patient prognosis.
- Existing DRs-targeting drugs for neurological disorders are being explored for cancer therapy.
Purpose of the Study:
- To review the role of dopamine receptors in cancer.
- To evaluate the therapeutic potential of targeting DRs in neoplastic diseases.
- To analyze the impact of DRs modulation on tumor progression and cancer cell biology.
Main Methods:
- Comprehensive literature review of studies on dopamine receptors in cancer.
- Analysis of preclinical and clinical data regarding DRs expression and targeting.
- Examination of high-prevalence neoplasms as examples to illustrate DRs' role.
Main Results:
- Dopamine receptors are confirmed as viable therapeutic targets in specific cancer types.
- Evidence for DRs' role in tumor progression is contradictory or inconclusive for other receptor/disease combinations.
- The precise function of DRs in tumorigenesis varies depending on the specific receptor and cancer.
Conclusions:
- Dopamine receptors represent promising targets for novel cancer therapies.
- Further investigation is crucial to elucidate the complex role of DRs in tumor progression.
- Optimized therapeutic strategies targeting DRs require additional research for improved cancer management.
