Hormone News and Research

RSS

A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Hormone replacement therapy may reduce dementia risk for some women

Hormone replacement therapy (HRT) may reduce the risk of dementia, particularly for certain groups of women - according to a study from the University of East Anglia and the University of Exeter.

Higher BPA exposure tracked with higher estrogen and progesterone in women

Researchers found that higher urinary concentrations of BPA and several phthalate metabolites were associated with higher serum estrogen and progesterone levels in 90 premenopausal women from Iran. The cross-sectional study also identified positive associations for combined chemical exposures, although the authors cautioned that the mixture findings are exploratory and cannot establish causality.

Lancet review examines possible amyloid-beta transmission through blood transfusions

A review and opinion piece published in The Lancet and led by UCL (University College London) and UCLH researchers discusses the possibility that blood transfusions may inadvertently transmit harmful brain proteins, and whether additional safety measures are warranted as a precaution whilst further research is conducted to better understand these potential risks.

Study shows how prostate tumors rewire metabolism to resist therapy

Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

More coffee, higher testosterone? This study found a more complicated picture

Higher habitual coffee intake was associated with a leaner body composition, lower circulating branched-chain amino acids, and distinct cardiometabolic patterns in 2,264 middle-aged Finnish adults. Hormonal associations differed by sex, with broader testosterone- and SHBG-related patterns in men and more limited SHBG-related changes in women.

Semaglutide trial targets people with liver disease, obesity and alcohol addiction

A new study -- co-led by the University of Plymouth, University Hospitals Plymouth NHS Trust, and the NIHR Biomedical Research Centre: Nottingham -- is being launched into a treatment for people impacted by liver disease, obesity and alcohol addiction.

A decades-long study raises questions about sugary drinks and stomach cancer

A large prospective U.S. study followed more than 111,000 adults to examine whether sugar-sweetened and artificially sweetened beverage intake was associated with gastric cancer incidence. Researchers identified 278 gastric cancer cases over 3.2 million person-years and found that associations differed according to beverage type and level of consumption.

Estrogen fluctuations reshape brain connections, new study finds

A new study out of the University of Delaware shows that fluctuations in estrogen influence the brain, helping reshape connections between neurons.

Beauty tutorials in social media increase use of hormone-disrupting products by teens

Personal care products are among the largest everyday sources of exposure to endocrine-disrupting chemicals, and high schoolers who follow social media influencers or watch beauty tutorials seem to use considerably more of them, according to Rutgers researchers.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.

What is the optimal prostate-specific antigen cutoff to determine the success of prostate cancer treatment?

After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that the treatment is working.

Later-life estrogen therapy associated with lower risk of developing dementia

Use of hormone therapy later in life was associated with lower risk of developing dementia, according to a study published August 12, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Mitochondrial gene RTN4IP1 drives triple-negative breast cancer metastasis

Triple-negative breast cancer accounts for approximately 15% of all breast cancer cases. It is characterized by the absence of estrogen receptor, progesterone receptor, and HER2 expression, rendering it insensitive to conventional endocrine and targeted therapies.

Oxytocin selectively increases trusting behavior in men with low disposition to trust

For over 20 years, it has been a matter of dispute whether oxytocin bolsters trust. A new study conducted with the involvement of the University of Zurich now provides robust evidence that the hormone selectively increases trusting behavior in men with a low disposition to trust.
