Galectin-7 is a type of protein that belongs to the galectin family, which is known for its ability to bind to carbohydrates. It plays a significant role in various biological processes, including cell growth, differentiation, and apoptosis (programmed cell death). This protein is primarily found in epithelial tissues and is involved in immune responses and inflammation. Research has shown that Galectin-7 can influence cancer progression and metastasis. Its expression levels can vary in different types of tumors, making it a potential biomarker for cancer diagnosis and prognosis. Understanding its functions may lead to new therapeutic strategies in treating various diseases.
