The interleukin-6 family cytokine interleukin-11 regulates homeostatic epithelial cell turnover and promotes gastric tumor development
View abstract on PubMed
Summary
This summary is machine-generated.Interleukin-11 (IL-11) is elevated in gastric cancer and promotes tumor development by altering gene expression and causing precancerous changes. Reducing IL-11 shows potential in gastric cancer progression models.
Area Of Science
- Gastroenterology
- Oncology
- Molecular Biology
Background
- Gastric cancer is a leading cause of cancer mortality globally, often due to late detection.
- Interleukin-11 (IL-11), a cytokine, is known to be upregulated in human gastric cancer.
Purpose Of The Study
- To investigate the role of IL-11 in gastric cancer progression.
- To identify early molecular changes associated with gastric tumorigenesis.
Main Methods
- Examined IL-11's role in mouse gastric tumor models and human gastric tissues.
- Assessed the effects of IL-11 overexpression on gene expression in normal gastric mucosa.
- Identified a novel gene signature linked to early gastric tumorigenesis.
Main Results
- IL-11 was significantly upregulated in mouse models and human gastric cancer tissues.
- IL-11 blockade reduced gastric hyperplasia and tumorigenesis in mouse models.
- IL-11 administration induced a gene signature associated with precancerous changes in normal gastric mucosa.
Conclusions
- Elevated gastric IL-11 drives gastric cancer progression by altering proliferative and cytoprotective gene expression.
- IL-11 promotes precancerous cellular changes, highlighting its potential as a therapeutic target.
