Women’s Health
Women’s health, a vital aspect of medical science, encompasses various conditions unique to women’s physiological makeup. Historically, women were often excluded from clinical research, leading to a gap in understanding the intricacies of women’s health needs. However, recent advancements have highlighted the significant role that the microbiome plays in these conditions, offering new insights and potential therapies. MicrobiomeSignatures.com is at the forefront of exploring the microbiome signature of each of these conditions to unravel the etiology of these diseases and develop targeted microbiome therapies.
Microbiome Signatures identifies and validates condition-specific microbiome shifts and interventions to accelerate clinical translation. Our multidisciplinary team supports clinicians, researchers, and innovators in turning microbiome science into actionable medicine.

What was studied?
The study investigated relaxed fibronectin as a novel target for imaging endometriotic lesions. Researchers explored using a preclinical radiotracer, [111In]In-FnBPA5, which binds specifically to relaxed fibronectin, an extracellular matrix protein involved in the pathogenesis of diseases like cancer and fibrosis.
Who was studied?
The study involved preclinical experiments using mice and immunohistochemical analysis on tissue samples from mice and patients diagnosed with endometriosis.
What were the most important findings?
The radiotracer [111In]In-FnBPA5 accumulated in the mouse uterus, with uptake varying according to the estrous cycle, suggesting an increased abundance of relaxed fibronectin during estrogen-dependent phases. Immunohistochemical analysis on patient-derived tissues showed that relaxed fibronectin is preferentially located near the endometriotic stroma, supporting its potential as a target for imaging endometriosis.
What are the greatest implications of this study?
The findings that [111In]In-FnBPA5 uptake varies in the mouse uterus with the estrous cycle, indicating increased relaxed fibronectin during estrogen-dependent phases, hold significant implications for future research on endometriosis.
Biomarker Identification: Understanding the fluctuation of relaxed fibronectin could help identify biomarkers for endometriosis, enabling earlier and more accurate diagnosis.
Pathogenesis Insights: These results suggest that estrogen-driven changes in fibronectin might play a role in the development or exacerbation of endometriosis. This could lead to a better understanding of the disease’s underlying mechanisms.
Targeted Therapies: By highlighting the relationship between estrogen, fibronectin, and endometrial tissue changes, new therapeutic targets may be identified, paving the way for treatments that modulate fibronectin or its pathways.
Diagnostic Imaging: The study suggests that targeting relaxed fibronectin could significantly improve the diagnostic imaging of endometriosis. This approach may lead to developing a specific radiotracer for noninvasive detection of endometriotic lesions, potentially enhancing diagnosis accuracy and aiding in better disease management.
Clinical Application: The researchers also suggest using gallium-68 for potential clinical application, which could further refine imaging techniques and improve patient outcomes.
