    Correlation between microRNA-34a levels and lens opacity severity in age-related cataracts

    MicroRNA 34a (miR-34a) is involved in regulating tissue senescence. However, the role of miR-34a in age-related cataracts is unclear. In this study, we evaluated the correlations among the severity of lens opa...
