Insights
Autophagy markers Beclin1 and LC3A show varying expression in pediatric hepatic steatosis, correlating with fibrosis and liver architecture. This highlights autophagy
Area of Science:
- Hepatology
- Cell Biology
- Pediatric Gastroenterology
Background:
- Pediatric hepatic steatosis is a growing global health concern and a leading cause of chronic liver disease in children.
- Lipophagy, a key cellular process, is implicated in the development and progression of hepatic steatosis.
Purpose of the Study:
- To investigate the immunohistochemical expression of Beclin1 and LC3A in pediatric hepatic steatosis.
- To correlate Beclin1 and LC3A expression with clinicopathological parameters in pediatric patients.
Main Methods:
- Studied 81 Egyptian pediatric patients with hepatic steatosis and 21 controls.
- Utilized Beclin1 and LC3A antibody staining on hepatic tissue specimens.
- Categorized patients into chronic liver disease (CLD) and inborn error of metabolism (IEM) groups.
Main Results:
- Higher Beclin1 expression correlated with advanced fibrosis and distorted liver architecture in the CLD group.
- LC3A expression was higher in controls compared to CLD and IEM groups.
- Increased LC3A positivity was linked to advanced fibrosis and distorted liver architecture in the IEM group.
Conclusions:
- Differential expression of Beclin1 and LC3A reflects varying autophagy activity in pediatric hepatic steatosis.
- Autophagy markers' expression is associated with disease progression and etiology in pediatric hepatic steatosis.
Abstract:
Hepatic steatosis has become the most common cause of chronic liver disease among children worldwide. Lipophagy has been considered as a pathway affecting steatosis development and progression.
Objective:
this study aimed to evaluate the immunohistochemical expression of Beclin1 and LC3A in pediatric hepatic tissues with steatosis and to correlate their expression with clinicopathological parameters.
Methods:
this study included 81 Egyptian pediatric patients with hepatic steatosis and 21 pediatric cases without hepatic steatosis. All specimens were stained by Beclin1 and LC3A antibodies. According to final diagnosis obtained from Pediatric Hepatology department, patients were divided into two groups: chronic liver disease (CLD) group that included 45 cases and inborn error of metabolism (IEM) group that included 36 cases.
Results:
higher beclin1 expression was significantly correlated with higher stages of fibrosis and distorted liver architecture in CLD group, (P=0.043) for both. The control group showed higher positivity, percentage, as well as the median values of the H score of LC3A expression than did the CLD group or the IEM group (P=0.055, 0.001, and 0.008, respectively). Higher positivity of LC3A was significantly associated with higher stages of fibrosis and distorted liver architecture in the studied IEM group (P=0.021) for both.
Conclusions:
Varying intensity grades of LC3A and Beclin 1 immunohistochemical expression demonstrate the variation of autophagy at different phases of pediatric hepatic steatosis and varied disease etiology.
