Genetic biomarker linked to subcutaneous growth hormone dose-response

The interindividual variability of response to subcutaneously applied protein-based drugs remains poorly understood. However, defining genetic markers that can be associated with biological effects of such drugs may improve the understanding of individual variability of response and even drug resistance.

Testosterone and body fat are controlled by the same genes

Genes that control percentage of body fat are also responsible for circulating levels of testosterone in men, research published in the latest edition of Clinical Endocrinology shows. The research shows a 23% overlap between the genes that control testosterone and those that regulate body fat composition, suggesting that these two variables are partly controlled by the same set of genes.

study shows compounds from soy affect brain and reproductive development

Two hormone-like compounds linked to the consumption of soy-based foods can cause irreversible changes in the structure of the brain, resulting in early-onset puberty and symptoms of advanced menopause in research animals, according to a new study by researchers at North Carolina State University. The study is a breakthrough in determining how these compounds can cause reproductive health problems, as well as in providing a key building block for how to treat these problems.
