Extracellular Vesicular miRNA in Pancreatic Cancer: From Lab to Therapy

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Pancreatic cancer is a lethal gastrointestinal malignancy with late-stage diagnosis and high mortality.
• Current screening protocols for high-risk individuals are not standardized.
• Chemotherapy and radiotherapy show limited efficacy, necessitating novel therapeutic approaches.

Purpose of the Study:

• To review the role of extracellular vesicles (EVs) and their associated microRNAs (miRNAs) in pancreatic cancer.
• To explore the impact of EV-mediated intercellular communication on pancreatic cancer pathogenesis.
• To highlight the therapeutic potential of EV-associated miRNAs as biomarkers and drug-delivery systems.

Main Methods:

• Literature review focusing on recent studies of pancreatic cancer, tumor microenvironment, extracellular vesicles, and miRNAs.
• Analysis of the mechanisms by which EVs mediate intercellular communication in pancreatic cancer.
• Evaluation of the role of EV-associated miRNAs in cancer progression, metastasis, and therapy resistance.

Main Results:

• The tumor microenvironment, including extracellular matrix and immune cells, critically influences pancreatic cancer.
• EVs facilitate intercellular communication by transferring biomolecules like miRNAs, proteins, and lipids.
• EV-mediated communication significantly affects pancreatic cancer proliferation, angiogenesis, metastasis, and drug resistance.

Conclusions:

• EV-associated miRNAs are pivotal in pancreatic cancer progression, metastasis, and drug resistance.
• EVs represent promising biomarkers for early detection and prognosis.
• EVs hold potential as innovative drug-delivery vehicles for pancreatic cancer therapy.
