The impact of oligodendroglial Serpina3n depeletion on brain aging in mice


ABSTRACT: This study investigates the role of oligodendroglial Serpina3n in brain aging by examining its depletion using Olig2-Cre Serpina3n flox/flox mice model. To assess the molecular impact of oligodendroglial Serpina3n depletion on brain aging, RNA-seq was performed on forebrain samples from three experimental groups: 1) Young Wild-Type Mice (2-month-old): Representing baseline gene expression in a young, healthy brain; 2) Aged Wild-Type Mice (22-month-old): Serving as a control group to analyze age-related changes in gene expression without genetic modifications. 3) Aged Olig2-Cre Serpina3n flox/flox mice (22-month-old): Assessing the effects of oligodendroglial Serpina3n depletion on the transcriptomic profile of aged brains. The experiment aims to identify gene expression changes associated with normal brain aging by comparing young and aged wild-type mice, determine the specific impact of oligodendroglial Serpina3n depletion on the aged brain by comparing aged wild-type mice to aged knockout mice, and highlight molecular mechanisms influenced by Serpina3n in the context of brain aging. This design allows for a comparative analysis of aging-related transcriptional changes and the specific contribution of Serpina3n depletion in this process.
