Summary of the Research on sex-Specific Disease Pathways
This research, conducted by an international team analyzing nearly 9,000 patient samples across 25 tissues and over 100 diseases, reveals notable differences in the biological pathways underlying disease co-occurrence in men and women.
Key Findings:
* Sex-Specific pathways: The same diseases arise through different biological mechanisms depending on sex. In women, immune system and metabolism processes are dominant, while in men, DNA and tissue repair mechanisms are more prominent.
* Diagnostic & treatment Biases: historically, research focused on male models, leading to biases in diagnosis and less effective treatments for women. this study reinforces the need to analyze data separately by sex.
* Disease Co-occurrence Differences: Diseases like type 2 diabetes and certain cancers show different associations in men and women, mediated by distinct biological mechanisms.
* Drug Response Variability: Common medications (metformin, chemotherapies, bronchodilators) have different associations with disease risk in men and women, suggesting varying efficacy and side effects. For example, metformin’s association with liver cancer differed between sexes due to hormonal and metabolic differences.
* Precision Medicine Implications: Integrating sex as a fundamental biological variable is crucial for developing a more precise and equitable medicine, preventing adverse effects, and tailoring treatments to individual biological realities.
* Need for Further Research: The identified trends require confirmation in other populations to generate robust hypotheses.
the study highlights the critical need to move beyond a “one-size-fits-all” approach to medicine and embrace a sex and gender perspective in research and clinical practice to ensure fairer and more effective healthcare for all.
The research was supported by the Barcelona Supercomputing Center’s (BSC) programs focusing on sex/gender biases in biomedicine (Bioinfo4Women) and the study of comorbidity (COMMUTE and HEALED).
