Abstract:
Retraction: "MicroRNA-520a-3p suppresses epithelial-mesenchymal transition, invasion, and migration of papillary thyroid carcinoma cells via the JAK1-mediated JAK/STAT signaling pathway," by Chang-Long Bi, Ying-Qi Zhang, Bo Li, Min Guo, Yi-Li Fu, J Cell Physiol. 2019; 4054-4067: The above article, published online on 12 September 2018 in Wiley Online Library (https://doi.org/10.1002/jcp.27199), has been retracted by agreement between the journal's Editor in Chief, Prof. Dr. Gregg Fields, and Wiley Periodicals LLC. The retraction has been agreed after the authors asked to correct their article. An investigation revealed several flaws and inconsistencies between results presented and experimental methods described. Thus the editors consider the conclusions of this article to be invalid. The authors were not available for a final confirmation of the retraction.
Insights
This study on papillary thyroid carcinoma is retracted due to invalid conclusions. Flaws in experimental methods and results led to the retraction of microRNA-520a-3p findings.
Area of Science:
- Oncology
- Molecular Biology
- Cell Signaling
Context:
- Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer.
- Epithelial-mesenchymal transition (EMT), invasion, and migration are critical processes in cancer progression.
- The JAK/STAT signaling pathway plays a role in various cellular functions, including cancer development.
Purpose:
- To investigate the role of microRNA-520a-3p in suppressing EMT, invasion, and migration of papillary thyroid carcinoma cells.
- To elucidate the mechanism involving the JAK1-mediated JAK/STAT signaling pathway.
Summary:
- The article investigated microRNA-520a-3p's role in papillary thyroid carcinoma.
- It proposed a mechanism involving the JAK1-mediated JAK/STAT pathway.
- The study has been retracted due to identified flaws and inconsistencies.
Impact:
- The retraction invalidates the previously reported findings on microRNA-520a-3p and its mechanism in PTC.
- This highlights the importance of rigorous methodology and data verification in scientific research.
- Further research is needed to clarify the role of microRNA-520a-3p in thyroid cancer.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....
