ATF4 Cancer Research Results

ATF4, Activating Transcription Factor 4: Click to Expand ⟱
Source:
Type: protein
ATF4 (Activating Transcription Factor 4) is a protein that plays a crucial role in various cellular processes, including stress response, cell growth, and differentiation.
ATF4 is overexpressed in several types of cancer, including breast, lung, colon, and pancreatic cancer. The overexpression of ATF4 can contribute to cancer cell growth, survival, and resistance to chemotherapy.
ATF4 promotes cancer cell growth by regulating the expression of genes involved in cell proliferation, angiogenesis, and metastasis. It also inhibits apoptosis (programmed cell death) by regulating the expression of anti-apoptotic genes.
