Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal types of cancer, and novel treatment regimens are direly needed. Epigenetic regulation contributes to the development of various cancer types, but its role in the development of and potential as a therapeutic target for PDAC remains underexplored. Here, we show that PRMT1 is highly expressed in murine and human pancreatic cancer and is essential for cancer cell proliferation and tumorigenesis. Deletion of PRMT1 delays pancreatic cancer development in a KRAS-dependent mouse model, and multi-omics analyses reveal that PRMT1 depletion leads to global changes in chromatin accessibility and transcription, resulting in reduced glycolysis and a decrease in tumorigenic capacity. Pharmacological inhibition of PRMT1 in combination with gemcitabine has a synergistic effect on pancreatic tumor growth in vitro and in vivo. Collectively, our findings implicate PRMT1 as a key regulator of pancreatic cancer development and a promising target for combination therapy.

Background The relationship between physical activity and incident pancreatic cancer is poorly defined, and the evidence to date is inconsistent, largely due to small sample sizes and insufficient incident outcomes. Using the UK Biobank cohort dataset, the association between physical activity levels at recruitment and incident pancreatic ductal adenocarcinoma (PDAC) at follow-up was analysed. Method Physical activity, the key exposure, was quantified using Metabolic Equivalent Task (MET) values and categorised into walking, moderate, and vigorous activity.

The primary node molecules in the cell signaling network in cancer tissues are maladjusted and mutated in comparison to normal tissues, which promotes the occurrence and progression of cancer. Pancreatic cancer (PC) is a highly fatal cancer with increasing incidence and low five-year survival rates. Currently, there are several therapies that target cell signaling networks in PC.

Background: Pancreatic cancer involving the pancreas neck and body often invades the retroperitoneal vessels, making its radical resection challenging. Multimodal treatment strategies, including neoadjuvant therapy, surgery, and postoperative adjuvant therapy, are contributing to a paradigm shift in the treatment of pancreatic cancer. This strategy is also promising in the treatment of pancreatic neck-body cancer.

In a recent study by He , the nomogram integrates postoperative serum tumor markers such as carbohydrate antigen 19-9 and carcinoembryonic antigen, thereby improving the accuracy of identifying high-risk patients compared to relying solely on preoperative markers, which has significant implications for customizing adjuvant therapy and potentially improving outcomes for this aggressive form of cancer. However, the study's single-center design and short follow-up period may limit the generalizability of its findings and potentially introduce reporting bias. Future studies could consider additional confounding factors, such as adjuvant chemotherapy and variations in surgical techniques, to improve the model's accuracy.
