Bacterial infection is recognized as one of the biggest global health threats, causing millions of people's death every year(Wang et al., 2020). Traditional antibiotics-based therapies have been widely utilized to control this issue(Kohanski et al., 2010); however, their excessive use leads to the emergence of antibioticresistant bacteria, endangering to human health(Levy and Marshall, 2004).

Tumor-protein 53(p53)is a transcription factor(TF)encoded by TP53(Trp53 in mice)and is a master regulator of tumor-suppressive programs'.Importantly,TP53 is the most frequently mutated gene in human cancer,and its loss of function contributes to tumor development,exemplified by variable p53 mutations detected in 50%-75%of pancreatic cancers.2 From these perceptions,a number of targets transcribed by p53 that confer tumor suppression have been ***,our understanding of how p53 prevents normal cells from initiating tumorigenesis is still *** complement this limitation,herein,we established a new approach to identify underlying effectors transcribed by p53 in normal physiology.
