Retinal gene expression responses to aging are sexually divergent.

ABSTRACT:

Purpose

Sex and age are critical factors in a variety of retinal diseases but have garnered little attention in preclinical models. The current lack of knowledge impairs informed decision making regarding inclusion and design of studies that incorporate both sexes and/or the effects of aging. The goal of this study was to examine normative mouse retina gene expression in both sexes and with advancing age.

Methods

Retinal gene expression in female and male C57BL/6JN mice at 3 months and 24 months of age were compared for sex differences and aging responses through whole transcriptome microarray analysis. Sex differences and age-related changes were examined in the context of cellular pathways and processes, regulatory patterns, and cellular origin, as well as for overlap with
