Research suggests that fatty acid synthase (FASN) may play a role in promoting lymph node metastasis in cervical cancer. The mechanisms behind this process are not entirely clear, but may involve cholesterol reprogramming, lymphangiogenesis, and potentially other factors such as tumor microenvironment and non-coding RNAs. The relationship between FASN and cancer metastasis may also be relevant to other types of cancer, including gastric, hepatocellular, and non-small cell lung cancer.
