Pancreatic cancer is one of the most common malignancies. Unfortunately, the lack of effective methods of treatment and diagnosis has led to poor prognosis coupled with a very high mortality rate. So far, the pathogenesis and progression mechanisms of pancreatic cancer have been poorly characterized. Exosomes are small vesicles secreted by most cells, contain lipids, proteins, and nucleic acids, and are involved in diverse functions such as intercellular communications, biological processes, and cell signaling. In pancreatic cancer, exosomes are enriched with multiple signaling molecules that mediate intercellular communication with control of immune suppression, mutual promotion between pancreas stellate cells and pancreatic cancer cells, and reprogramming of normal cells. In addition, exosomes can regulate the pancreatic cancer microenvironment and promote the growth and survival of pancreatic cancer. Exosomes can also build pre-metastatic micro-ecological niches and facilitate the targeting of pancreatic cancer. The ability of exosomes to load cargo and target allows them to be of great clinical value as a biomarker mediator for targeted drugs in pancreatic cancer.
Background: Pancreatic ductal adenocarcinoma (PDCA) is one of the malignant tumors with the worst prognosis with a 5-year survival rate of <1%, which is known as the "king of cancers". At present, there is a lack of effective early diagnosis and treatment plan for pancreatic cancer. Therefore, there is an urgent need to understand the molecular mechanisms of pancreatic cancer to generate innovative approaches for the development of effective early diagnosis and treatment strategies.Methods: In this study, we performed single gene pan-cancer analysis, gene co-expression analysis and gene regulatory correlation analysis to understand the molecular mechanism of CD248 in pancreatic cancer using bioinformatics tools. Additionally, we provided potential molecular targets for pancreatic cancer treatment by constructing the lncRNA-miRNA-gene network axis.Results: The results showed that CD248 is differentially expressed in normal and tumor tissues, and abnormally high expression predicts poor prognosis, is a proto-oncogene in pancreatic cancer. Besides, CD248 is associated with angiogenesis of tumors. We obtained three new lncRNA-miRNA-gene network axes, namely AC008040.1-hsa-miR-200c-3p-CD248 axis, AC055822.1-hsa-miR-200c-3p-CD248 axis, RRN3P2-hsa-miR-200c-3p-CD248 axis that provide promising molecular targets for anti-angiogenic therapy and diagnostic biomarkers for pancreatic cancer.Conclusion: In conclusion, this study shows that over-expression of CD248 (TEM1/CD164L1/Endosialin) is always present in breast cancer and predicts a poor prognosis, associated with tumor angiogenesis, suggesting it as an attractive therapeutic target for pancreatic cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
