[Research progress on the effect of selective autophagy receptor p62 on fibrotic diseases]
Abstract:
Selective autophagy keeps cell homeostasis by degrading aggregated proteins, damaged or over-abundant organelles, and other cytoplasmic substances. The maintenance of its normal function needs to ensure that the autophagy receptor can effectively recognize and isolate undegraded substances. As an important autophagy receptor protein, p62 participates in the process of selective autophagy by mediating multiple signaling pathways. Fibrosis is a pathological feature of most chronic inflammatory diseases. When fibrosis develops for a long time, it will cause substantial scar formation and eventually lead to cell dysfunction and organ failure. The accumulation, overexpression and ectopic expression of p62 can aggravate the occurrence and development of lung, liver and kidney fibrosis diseases. Therefore, it is very critical to explore the effect of selective autophagy receptor p62 on fibrotic diseases.
Insights
Selective autophagy maintains cell balance. The p62 protein, an autophagy receptor, is crucial for this process and its dysfunction contributes to fibrotic diseases like lung, liver, and kidney fibrosis.
Area of Science:
- Cellular Biology
- Molecular Biology
- Pathology
Background:
- Selective autophagy is essential for cellular homeostasis, clearing damaged components via autophagy receptors.
- p62 is a key autophagy receptor protein involved in various signaling pathways.
- Fibrosis, characterized by scarring, leads to organ dysfunction and failure in chronic inflammatory diseases.
Purpose of the Study:
- To investigate the role of the selective autophagy receptor p62 in the development of fibrotic diseases.
- To understand how p62 accumulation, overexpression, and ectopic expression impact lung, liver, and kidney fibrosis.
Main Methods:
- The study focuses on the molecular mechanisms of selective autophagy and p62.
- Analysis of p62's involvement in signaling pathways relevant to fibrosis.
- Examination of p62's expression patterns in fibrotic conditions.
Main Results:
- p62 plays a significant role in selective autophagy.
- Accumulation, overexpression, and ectopic expression of p62 exacerbate lung, liver, and kidney fibrosis.
- p62's function is critical in preventing fibrotic disease progression.
Conclusions:
- Selective autophagy receptor p62 is a critical factor in fibrotic diseases.
- Targeting p62 may offer therapeutic strategies for fibrotic conditions.
- Further research into p62's role is vital for understanding and treating fibrosis.
