STAT proteins, or Signal Transducer and Activator of Transcription proteins, are a family of transcription factors that play a crucial role in various cellular processes, including cell growth, differentiation, and apoptosis. They are activated by cytokines and growth factors and are involved in signaling pathways that can influence cancer development and progression.
STAT proteins can promote cell division and survival, leading to increased tumor growth.
Many cancers exhibit overexpression of certain STAT proteins, particularly STAT3 and STAT5.
