KISS1 in metastatic cancer research and treatment: potential and paradoxes

Area of Science:

• Oncology
• Endocrinology
• Molecular Biology

Background:

• The KISS1 gene was initially identified for its role in suppressing cancer metastasis.
• Its function as a neuropeptide influencing numerous physiological processes is increasingly recognized.
• Clinical trials are exploring KISS1 in reproductive and metabolic conditions, but its oncologic applications remain under investigation.

Purpose of the Study:

• To review and synthesize data from both cancer and non-cancer research on KISS1 signaling.
• To identify shared and distinct signaling pathways relevant to clinical development in oncology.
• To inform the therapeutic and biomarker potential of KISS1 in cancer treatment.

Main Methods:

• Literature review collating data from diverse scientific fields.
• Analysis of signaling pathways involving KISS1 and its receptor.
• Examination of evidence for and against the canonical KISS1 pathway.

Main Results:

• KISS1 exhibits complex signaling with implications beyond metastasis suppression.
• Shared and disparate signaling mechanisms exist between cancer and non-cancer contexts.
• The canonical KISS1 pathway, involving kisspeptin 54 and its receptor, requires further scrutiny.

Conclusions:

• Understanding the multifaceted roles of KISS1 is crucial for realizing its therapeutic potential.
• Further investigation into KISS1 signaling covariates is needed for clinical applications.
• KISS1 holds promise as a target for cancer therapeutics and biomarkers.
