Sex Differences and Aging
Brittany Lasseigne

TL;DR
This paper discusses how sex differences influence aging and highlights the importance of considering these differences in biomedical research.
Contribution
The paper emphasizes the need to integrate sex as a biological variable in aging research through policy and study design.
Findings
Sex differences impact molecular signatures of aging and tissue-specific aging processes.
Biological sex modifies the effects of lifestyle interventions such as exercise on aging.
Policies like SABV and SAGER aim to address the underrepresentation of sex differences in research.
Abstract
Sex differences are critical for deciphering normal biological function, including the aging process. However, the biological influence of sex, including metabolic, genomic, epigenetic, immunological, hormonal, and other differences between males and females, has been under-addressed in biomedical research. This gap has prompted key policies, notably the National Institutes of Health’s Sex as a Biological Variable (SABV) and the Sex and Gender Equity in Research (SAGER) guidelines, designed to motivate researchers to consider sex differences in their studies. This session focuses on the impact of sex across the lifespan. Our presentations and discussion will center on identifying and characterizing sex-specific molecular signatures of aging, their role in developmental programming, and their influence on tissue-specific aging. We will also examine how biological sex modifies the effects…
