Exploring STK3 in melanoma: a systematic review of signaling networks and therapeutic opportunities.

Melanoma is an aggressive cancer that disregards both the MAPK and Hippo signaling pathways. This systematic review explores STK3 function in the Hippo pathway to regulate networks and its therapeutic potential in melanoma. From 1991 to 2024, we studied how STK3 interacts with the MAPK/ERK pathway to promote apoptosis and inhibit tumor growth. STK3 controls cell growth, apoptosis, and metastasis via the Hippo and MAPK pathways. It is a melanoma tumor suppressor. Some ways to target STK3 are to directly activate it, stop downstream effectors like YAP/TAZ from working, or use existing BRAF inhibitors together with other methods. Despite advancements, challenges in STK3 drug development persist, warranting further investigation. This review examined the role of STK3 in the development of melanoma and identified potential vulnerabilities for therapeutic intervention.
