In multiple cancers, including breast cancer, gastric cancer, and cervical cancer, high expression of GSDMB correlates with poor prognosis, promoting cancer cell proliferation, invasion, and metastasis through interactions with signaling pathways such as STAT3 and mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK). This evidence concerns the gene WNK2 and breast cancer.
