A study by Picot et al. suggested that mammaglobin-A can promote tumor cell proliferation, migration, and invasion, activating several critical signaling pathways such as mitogen-activated protein kinase (MAPK), focal adhesion kinase (FAK), matrix metalloproteinases (MMPs), and nuclear factor kappa B (NF-κB), all essential in cancer development and metastasis [85]. The gene discussed is SCGB2A2; the disease is cancer.
