Unveiling LGR5: Prostate cancer's hidden stem cell and treatment target

Prostate cancer poses a significant risk to the well-being and way of life of countless men, with an increased likelihood of relapse recorded following modern treatment. This highlights the need for innovative approaches, specifically targeting LGR5. This systematic review aims to establish a connection between LGR5 and the various signaling pathways involved in the progression of prostate cancer. LGR5, a gene targeted by Wnt signaling, encodes a receptor protein that serves as a prognostic biomarker for stem cells and indicates the presence of cancer stem cells in colorectal and gastrointestinal cancers. The functions of LGR5 include processes such as cell proliferation, differentiation, and signaling pathways. Any modifications to the LGR5 gene, whether caused by mutations or mechanical stimuli, can lead to the development of treatment-resistant stem cell cancers. This review examines the molecular mechanisms associated with LGR5 and emphasizes methodologies aimed at targeting LGR5 to enhance understanding and promote the development of LGR5-specific therapies.
