Most patients diagnosed with pancreatic cancer are initially at an advanced stage, and radiotherapy resistance impact the effectiveness of treatment. This study aims to investigate the effects of endocrine disruptor Di-(2-ethylhexyl) phthalate (DEHP) on various biological behaviors and the radiotherapy sensitivity of pancreatic cancer cells, as well as its potential mechanisms. Our findings indicate that exposure to DEHP promotes the proliferation of various cancer cells, including those from the lung, breast, pancreas, and liver, in a time- and concentration-dependent manner. Furthermore, DEHP exposure could influence several biological behaviors of pancreatic cancer cells in vivo and vitro. These effects include reducing cell apoptosis, causing G0/G1 phase arrest, increasing migration capacity, enhancing tumorigenicity, elevating the proportion of cancer stem cells (CSCs), and upregulating expression levels of CSCs markers such as CD133 and BMI1. DEHP exposure can also increase radiation resistance, which can be reversed by downregulating BMI1 expression. In summary our research suggests that DEHP exposure can lead to pancreatic cancer progression and radiotherapy resistance, and the mechanism may be related to the upregulation of BMI1 expression, which leads to the increase of CSCs properties.

Background: Pancreatic ductal adenocarcinoma (PDAC) requires innovative therapeutic strategies to counteract its progression and metastatic potential. Since the majority of patients are diagnosed with advanced metastatic disease, treatment strategies targeting not only the primary tumor but also metastatic lesions are needed. Tumor-Associated Macrophages (TAMs) have emerged as central players, significantly influencing PDAC progression and metastasis.

Purpose: The association between statin use and cancer survival has been investigated in previous studies with conflicting findings. This study aimed to assess the association between statin use following cancer diagnosis and survival in six common cancers using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database.
Methods: Individuals aged ≥ 66 years diagnosed with prostate cancer, colorectal cancer, lung cancer, bladder cancer, pancreatic cancer, or non-Hodgkin lymphoma (NHL) from 2008 through 2017 were identified.

The gut microbiome, a complex community of trillions of microorganisms in the intestines, is crucial in maintaining human health. Recent advancements in microbiome research have unveiled a compelling link between the gut microbiome and cancer development and progression. Alterations in the composition and function of the gut microbiome, known as dysbiosis, have been implicated in various types of cancer, including, esophageal, liver, colon, pancreatic, and gastrointestinal.

Pancreatic ductal adenocarcinoma (PDAC) has a very poor prognosis, and the main objective of this study was to reveal the specific mechanism of action of TN-CAP1-mediated macrophage-fibroblast crossinulation in the progression of PDAC, and to evaluate the function and potential therapeutic value of ITGB5 and ITGB1 recombinant proteins in this process. The expression of TN-CAP1 in tumor tissues of PDAC patients was analyzed by immunohistochemistry and compared with normal pancreatic tissues. The co-culture system of macrophages and fibroblasts was constructed using in vitro cell culture model.
