This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Basic Concepts, Subject name: Pathology
All of the following are transcription factors activated by signal transduction pathways of hyperophy, except: 
Select and explain. 
A. GATA4, B. NFAT, C. MEF2, D. MLL1
D: MLL1
Answer: D: MLL1 
Explanation: - Signaling pathways which trigger hyperophy activate a set of transcription factors such as:- GATA4 Nuclear factor of activated T-cells (NFAT) Myocyte enhancer factor-2 (MEF2). These transcription factors work in coordination to increase the synthesis of muscle proteins that are responsible for hyperophy. - MLL1 (Mixed lineage leukemia protein-1) is a gene involved in acute leukemia.
