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.

Minimally invasive surgery(MIS)has significantly progressed and emerged as the preferred approach for various gastrointestinal procedures,including gastrectomy,cholecystectomy,and various colorectal surgeries(1).However,the widespread acceptance of robotic surgery in liver resection has encountered obstacles,attributed to factors such as the lack of appropriate surgical instruments,the intricate learning curve,and safety ***,the utilization of MIS in liver resection is linked to decreased blood loss,reduced post-operative pain,shorter hospital stays,and lower morbidity rates compared to both open and laparoscopic liver resection procedures(2).

Curative resection is undoubtedly the most important prognostic factor in perihilar cholangiocarcinoma(1).The current consensus of surgical resection of perihilar cholangiocarcinoma consists of hemihepatectomy,including caudate lobectomy and aggressive lymphadenectomy,depending on the extent of bile duct *** decisions on whether to resect the right or left liver and whether to perform an extended hepatectomy or trisectionectomy are all aimed at obtaining negative radial and longitudinal margins(2,3).
