Abstract
Pancreatic cancer (PC) is a digestive system tumor that is highly malignant, with an increasing incidence rate, poor prognosis, and a low 5-year survival rate. The overwhelming majority of patients with PC are in an advanced stage at the time of diagnosis and have lost the opportunity for radical surgery. The efficacy of radiotherapy and chemotherapy for PC is very poor. Therefore, it is of great significance to explore the mechanisms of PC development and new therapeutic targets. Exosomes are extracellular vesicles that mediate the exchange of substances and information between cells. In recent years, exosomes have been shown to play a key role in the development and progression of PC and might be useful for both its diagnosis and treatment. This article reviews the composition and function of exosomes and their roles in the development, diagnosis, and treatment of PC.

Abstract
Pancreatic cancer is one of the most aggressive human malignancies and is associated with a dismal prognosis, which can be contributed to its atypical symptoms, metastatic propensity, and significant chemoresistance. Emerging evidence shows that pancreatic cancer cell-derived exosomes (PEXs) play critical roles in tumorigenesis and tumor development, as they are involved in drug resistance, immune evasion and metabolic reprograming, and distant metastasis of pancreatic cancer. Their numerous differentially expressed and functional contents make PEXs promising screening tools and therapeutic targets, which require further exploration. In this review, we focus on the functions of PEX contents and their clinical implications in pancreatic cancer.

Abstract
Exosomes, extracellular vesicles with diameters ranging from 30 to 150 nm, are widely present in various body fluids. Recently, microRNAs (miRNAs) have been identified in exosomes, the biogenesis, release, and uptake of which may involve the endosomal sorting complex required for transport (ESCRT complex) and relevant proteins. After release, exosomes are taken up by neighboring or distant cells, and the miRNAs contained within modulate such processes as interfering with tumor immunity and the microenvironment, possibly facilitating tumor growth, invasion, metastasis, angiogenesis and drug resistance. Therefore, exosomal miRNAs have a significant function in regulating cancer progression. Here, we briefly review recent findings regarding tumor-derived exosomes, including RNA sorting and delivering mechanism. We then describe the intercommunication occurring between different cells via exosomal miRNAs in tumor microenvironmnt, with impacts on tumor proliferation, vascularization, metastasis and other biological characteristics. Finally, we highlight the potential role of these molecules as biomarkers in cancer diagnosis and prognosis and tumor resistance to therapeutics.

Int J Mol Med 2018; 42:1637-1643. [PMID: 29845190 DOI: 10.3892/ijmm.2018.3706] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2016] [Accepted: 10/19/2017] [Indexed: 11/06/2022] Open
Abstract
MicroRNA‑23b‑3p (miR‑23b‑3p) has been reported to be involved in the pathogenesis of a number of diseases, including non‑small cell lung cancer and gastric cancer, by acting on different signaling pathways. The present study aimed to understand the association between the miR‑23b‑3p level of intracranial aneurysms (IAs) and the mechanism involved. Computational analysis was used to search for the target of miR‑23b‑3p, and luciferase assay was used to validate the miRNA/target association. Western blot analysis and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were used to determine the expression of miR‑23b‑3p and phosphatase and tensin homolog (PTEN), and their expression in smooth muscle cells (SMCs) treated with miRNA mimic or inhibitor. Firstly, an online miRNA database (www.mirdb.org) was searched using the 'seed sequence' located within the 3'‑untranslated region of the target gene, and then PTEN was validated as the direct target gene via a luciferase reporter assay system. The negative regulatory association between miR‑23b‑3p and PTEN was determined through the analysis of the relative luciferase activity. Additionally, RT-qPCR and western blot analysis was performed in order to assess the mRNA and protein expression levels of PTEN among IA (n=32) and control (n=17) groups or cells treated with scramble control, miR‑23b‑3p mimics, PTEN siRNA and miR‑23b‑3p inhibitors to verify the negative regulatory association between miR‑23b‑3p and PTEN. Experiments were then performed to investigate the effect of miR‑23b‑3p and PTEN on the viability and apoptosis of pulmonary artery SMCs (PASMCs). The results showed that cells transfected with miR‑23b‑3p inhibitors suppressed the viability of SMCs by promoting the apoptosis of the cells compared with that of the scramble controls, while cells transfected with miR‑23b‑3p mimics and PTEN siRNA enhanced the viability of VSMCs by inducing apoptosis. This indicated that miR‑23b‑3p negatively interfered with the viability of the cells, while PTEN positively interfered with the viability of the cells. In conclusion, PTEN was found to be a virtual target of miR‑23b‑3p, and a negative regulatory association existed between miR‑23b‑3p and PTEN. miR‑23b‑3p and PTEN interfered with the viability and apoptosis of SMCs.

Abstract
BACKGROUND Pancreatic cancer (PC) remains one of the most fatal forms of cancer worldwide with incidence nearly equal to mortality. This is often attributed to the fact that diagnosis is often not made until later disease stages when treatment proves difficult. Efforts have been made to reduce the mortality of PC through improvements in early screening techniques and treatments of late-stage disease. Exosomes, small extracellular vesicles involved in cellular communication, have shown promise in helping understand PC disease biology. METHODS In this review, we discuss current studies of the role of exosomes in PC physiology, and their potential use as diagnostic and treatment tools. RESULTS Exosomes have a role in diagnosing pancreatic cancer and in understanding tumor biology including migration, proliferation, chemoresistance, immunosuppression, cachexia and diabetes, and have a potential role in therapy for pancreatic cancer. CONCLUSIONS Exosomal analysis is beneficial in demonstrating mechanisms behind PC growth and metastasis, immunosuppression, drug resistance, and paraneoplastic conditions. Furthermore, the use of exosomes can be beneficial in detecting early-stage PC and exosomes have potential applications as therapeutic targets.

Abstract
Pancreatic cancer is accompanied by a fibrotic reaction that alters interactions between tumor cells and the stroma to promote tumor progression. Consequently, strategies to target the tumor stroma might be used to treat patients with pancreatic cancer. We review recently developed approaches for reshaping the pancreatic tumor stroma and discuss how these might improve patient outcomes. We also describe relationships between the pancreatic tumor extracellular matrix, the vasculature, the immune system, and metabolism, and discuss the implications for the development of stromal compartment-specific therapies.
