Project summary

In routine clinical practice, diagnosis and treatment of endocrine diseases rely mostly on total steroid hormone levels. However, these hormones typically bind to specific proteins and albumin in circulation, with only a small fraction circulating freely. The 'free hormone hypothesis' proposes that this free fraction is responsible for the biological activity of hormones. Unfortunately, measuring free steroid hormone levels is technically challenging, limiting their implementation in clinical practice. In this research project, we aim to enhance the clinical applicability of free steroid hormone concentrations in patients with specific conditions and endocrine diseases, by using state-of-the-art methodology, particularly mass spectrometry, to investigate the clinical relevance of free steroid hormones. The main objectives of this PhD research project will be: - Development, optimization, and validation of methods to measure free steroid hormones - Investigating binding protein-hormone interactions - Studying the interplay between health parameters and free hormones.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
