INHBB and nasopharyngeal carcinoma: The decrease in INHBB expression is also associated with the overexpression of p53, which may further affect the invasiveness and metastatic potential of NPC cells.[41] INHBB acts as a tumor suppressor in nasopharyngeal carcinoma cells but acts a tumor promoter in gastric and colorectal cancers.[42,43] Currently, there is no research to verify the expression of INHBB in BLCA.
