AATF also referred to as, Apoptosis Antagonizing Transcription Factor, is a regulator of p53 in DNA damage response. It is known to inhibit apoptosis in vivo and be overexpressed in lung cancer. In Kras-driven lung adenocarcinoma if the deletion of AATF occurs then this results in delayed lung cancer formation mainly in a p53 dependent manner. Targeting AATF will be targeting tumor progression and putting a stop to it. AATF through the PI3K/Akt pathway can inhibit Ba. This then results in the activation of BCL-2 leading to immortality of these multiplying cells. We know that BCL-2 works in the survival pathway. Its job is to stop cell death. When a phosphate is added to Bad it could then prevent it from sequestering Bcl2, so Bcl2 can do its function. Bad prevents Bcl2 from doing its job. When Bad is bound to Bcl2, the cell will die, however, when Bad is not bound to Bcl2, Bcl2 will be active and it will stop cell death. In order to keep Bad inactive, protein 14-3-3 will make sure a phosphate is stuck on Bad.
