Since then, it has become apparent that KISS1, KPs, and KISS1R regulate the development and progression of several cancers but interestingly, while these molecules act as suppressors of tumorigenesis and metastasis in many cancers, in breast and liver cancer they function as promoters.
Our study suggested that KAI-1, KiSS-1, and MTA1 might be important biological markers involved in the carcinogenesis, metastasis, and invasion of gallbladder adenocarcinoma, but MTA1 is an independent factor of prognosis.
These results indicate metastin may function in decidualized endometrium to prepare for adequate placentation but this autocrine secretion of metastin is deregulated during oncogenesis to enable tumor cells to spread.
