ARTICLE HIGHLIGHTS
Research background
Ferroptosis is involved in the development of inflammatory diseases, but its relationship with acute hypertriglyceridemic pancreatitis (HTGP) remains unclear.
Research motivation
HTGP has serious morbidity and high mortality. At present, there is no more effective method except symptomatic treatment. Therefore, exploring the pathogenesis of HTGP and seeking more accurate therapeutic targets are of critical importance.
Research objectives
This study aimed to explore whether ferroptosis is involved in the process of HTGP and elucidate its potential mechanisms in a mouse model.
Research methods
Pancreatic tissues from the model animals were subjected to proteome sequencing analysis. The pathological changes and scores of the pancreas, lung, and kidney were determined using hematoxylin–eosin staining. The levels of serum amylase, triglyceride, and total cholesterol were measured with an automatic blood cell analyzer. Additionally, the serum levels of tumor necrosis factor-α, interleukin (IL)-6, and IL-1β were determined by enzyme linked immunosorbent assay. Malonaldehyde, glutathione, and Fe2+ were detected in the pancreas. Finally, immunohistochemistry was performed to assess the expression of ferroptosis-related proteins.
Research results
Proteome sequencing revealed that ferroptosis was involved in the process of HTGP and that NADPH oxidase 2 may participate in ferroptosis regulation.
Research conclusions
Ferroptosis was found to have an important role in HTGP and may be considered a potential target for clinical treatment.
Research perspectives
This discovery provides new insights into a better understanding of the pathogenesis of HTGP, which may be used as a novel therapeutic target. However, the regulatory mechanism needs to be further explored in the future.
