MACC1, or Metastasis associated in colon cancer 1, is an oncogene that plays a crucial role in the progression of many solid cancers [1,2,3,4,5,6,7,8]. It is involved in multiple biological processes such as tumor cell migration, invasion, proliferation, and metastasis [2,3,5,8]. MACC1 also influences the immune escape of cancer cells and may be associated with cancer resistance to radiation [1]. It is a key prognostic biomarker, significantly associated with tumor staging and patient survival in various cancers, including breast cancer [1,3,4].

In studies, MACC1 has been shown to promote the motility, invasion, and proliferation of colon cancer cells in vitro and cause tumor growth and metastasis in mice [7]. In colorectal cancer, curcumin was found to reduce MACC1 expression, restricting MACC1-induced proliferation and cell motility [6]. Additionally, GIPC1, identified as a protein binding partner and transcription factor of MACC1, regulates MACC1-driven metastasis, as its knockdown reduces MACC1-induced cell migration, invasion, tumor growth, and metastasis in mice [7].

In conclusion, MACC1 is a key driver in the metastatic processes of solid cancers, playing essential roles in tumor cell proliferation, migration, invasion, and metastasis. Mouse models, especially those involving knockdown or manipulation of genes related to MACC1, have been instrumental in revealing its functions in cancer-related biological processes, providing potential targets for anti-tumor and anti-metastatic intervention strategies [6,7].
