Retraction

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Context:

• Pancreatic cancer is a highly lethal malignancy with limited therapeutic options.
• MicroRNAs (miRNAs) are emerging as critical regulators in cancer development and progression.
• The Wnt/β-catenin signaling pathway plays a significant role in various cancers, including pancreatic cancer.

Purpose:

• To investigate the role of microRNA-300 (miR-300) in regulating pancreatic cancer cell behavior.
• To explore the underlying molecular mechanisms, including the involvement of the Wnt/β-catenin signaling pathway and CUL4B.
• To assess the impact of miR-300 on apoptosis, proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) in pancreatic cancer cells.

Summary:

• The article originally proposed that microRNA-300 (miR-300) suppresses pancreatic cancer progression by inhibiting proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT).
• It suggested that miR-300 exerts these effects by targeting CUL4B and modulating the Wnt/β-catenin signaling pathway.
• However, the study has been retracted due to the discovery of duplicated image elements in the experimental data, rendering the conclusions invalid.

Impact:

• The retraction highlights the importance of rigorous data verification in scientific publishing.
• It underscores the need for careful examination of image integrity in molecular biology research.
• The invalidation of findings necessitates further independent research to clarify the role of miR-300 in pancreatic cancer.
