Background/Aim:
Age-related cataract is the most important visual impairment all over the world. Epigenetic modifications, especially overexpression of histone deacetylases, have become the focus of interest for cataract development in recent years. Sirtuin 1 (SIRT1), a class II histone deacetylase and a member of the sirtuin family, is one of the best-characterized histone deacetylases and has a pivotal role in age-related diseases. However, the association of SIRT1 with age-related cataracts has not yet been fully elucidated. Therefore, we aimed to determine the expression of SIRT1 in age-related cataract patients.
Materials And Methods:
Expressions of SIRT1 were evaluated by quantitative polymerase chain reaction (qPCR) in patients and healthy controls. RNA samples were collected from the anterior capsule and peripheral blood samples of age-related cataract patients. Human lens epithelial cell line B3 and peripheral blood samples of healthy subjects were used as controls.
Results:
We determined that the expression of SIRT1 in blood and anterior capsule samples increased significantly compared to the control group (P < 0.05).
Conclusion:
The expression level of SIRT1 plays a vital role in the development of age-related cataract and it can be used as a biomarker. Thus, SIRT1 inhibitors can be used in the treatment of age-related cataract disease.
Insights
The expression of Sirtuin 1 (SIRT1) is significantly increased in age-related cataract patients. This finding suggests SIRT1 may serve as a biomarker for cataract development and a potential therapeutic target.
Area of Science:
- Ophthalmology
- Molecular Biology
- Epigenetics
Background:
- Age-related cataract is a leading cause of visual impairment globally.
- Histone deacetylases, particularly Sirtuin 1 (SIRT1), are implicated in age-related diseases.
- The specific role of SIRT1 in age-related cataract development requires further investigation.
Purpose of the Study:
- To investigate the expression levels of SIRT1 in patients with age-related cataracts.
- To determine if SIRT1 can serve as a biomarker for age-related cataract.
Main Methods:
- Quantitative polymerase chain reaction (qPCR) was used to measure SIRT1 expression.
- RNA samples were analyzed from the anterior lens capsule and peripheral blood of cataract patients and healthy controls.
- Human lens epithelial cell line B3 served as a control.
Main Results:
- SIRT1 expression was significantly elevated in both blood and anterior capsule samples from age-related cataract patients compared to controls (P < 0.05).
Conclusions:
- Elevated SIRT1 expression is associated with age-related cataract development.
- SIRT1 may function as a valuable biomarker for diagnosing age-related cataracts.
- SIRT1 inhibitors present a potential therapeutic strategy for treating age-related cataracts.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
