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.

Research challenges long standing beliefs about cannabis and male hormones

The effects of cannabis on the hormonal system and male fertility remain controversial within the scientific community. A study conducted by the University of Geneva (UNIGE), in collaboration with the Swiss Center for Applied Human Toxicology (SCAHT), provides a new answer by showing that cannabis use does not reduce testosterone levels in young men and may even increase its testicular synthesis.

Miniature lab grown circuits unlock hidden recovery paths for paralysis

Cambridge scientists have grown miniature circuits in the lab that mimic how the brain and spinal cord connect up, which underlies our movements. They used this model to show how damage to these connections previously considered 'irreversible' could, in fact, be reversible.

Vaginal bromocriptine may ease pain and heavy bleeding in adenomyosis

A pilot randomized controlled trial found that vaginal bromocriptine reduced menstrual bleeding, pelvic pain, menstrual duration, and cycle irregularity in women with adenomyosis compared with routine treatment.

Ghrelin rises in depression despite obesity’s usual appetite-hormone suppression

Researchers found that both acylated and deacylated ghrelin were elevated in unmedicated adults with major depressive disorder and obesity compared with non-depressed adults with obesity. The cross-sectional findings suggest ghrelin-system dysregulation may be linked to depression in obesity, but larger longitudinal studies are needed to test whether ghrelin is a reliable biomarker.

Wearable devices may help detect menstrual health changes earlier

Digital health tools, including wearables, provide critical data on menstrual health, enhancing understanding of hormonal fluctuations and women's well-being.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

New study tests vitamin D analog against pancreatic cancer

A small clinical trial led by Dana-Farber Cancer Institute researchers put a Salk Institute idea to the test in patients: that activating the vitamin D receptor can help reshape the protective environment surrounding pancreatic tumors in ways that could make the notoriously difficult-to-treat cancer more vulnerable to therapeutic treatments.

Tomato-soy juice curbs inflammation in obese adults

Drinking tomato-soy juice loaded with compounds shown in animal studies to promote health lowered pro-inflammatory proteins in healthy adults with obesity after four weeks, a new study found.

Estrogen decline alters brain cell matrix in older females

A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.

Roswell Park scientists present five key cancer studies at clinical meeting

The research findings of experts from Roswell Park Comprehensive Cancer Center will be featured during the American Society of Clinical Oncology (ASCO) annual meeting May 29 to June 2 at McCormick Place in Chicago.

Scientists map genetic variants behind prostate cancer therapy failure

Recently, the research group led by Dr. Dechao Feng, Lecturer at University College London (UCL) and Distinguished Research Fellow at Zhejiang Provincial People's Hospital, published a review entitled "Intratumoral Androgens and Genetic Variants Driving Therapy Resistance in Prostate Cancer".

New study shows how exercise hormone reduces multiple sclerosis symptoms

A new study offers clues as to why exercise can improve neurological symptoms in people with multiple sclerosis (MS).

Phase two clinical trial demonstrates dramatic mobility gains in children with severe fibrous dysplasia

Fibrous dysplasia is a rare skeletal disorder in which normal bone is gradually replaced by weak fibro-osseous tissue, leading to fractures, pain, deformities, and severe mobility impairment. In many patients, diseased bone tissue produces excessive amounts of fibroblast growth factor-23 (FGF23), a hormone that causes phosphate loss through the kidneys.

GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Aerobic exercise mitigates nanoplastic damage in female zebrafish

Using female zebrafish as a model, researchers have found that aerobic exercise may influence various connections in the body to lessen the damaging health impacts of environmental nanoplastics.

Gut-localized drug avoids systemic safety risks while reversing hormonal imbalances in mice

Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders in women of reproductive age. It can cause irregular periods, infertility, weight gain, insulin resistance, and elevated male hormone levels. Current treatments mainly focus on managing symptoms rather than addressing underlying causes.

Molecular profiling initiative seeks to uncover late breast cancer recurrence mysteries

The ECOG-ACRIN Cancer Research Group (ECOG-ACRIN), in collaboration with the SWOG Cancer Research Network (SWOG), has launched a new initiative to analyze paired original and recurrent tumor specimens from two practice-changing breast cancer clinical trials.

Global consortium renames polycystic ovary syndrome to reflect science

First, it was named after two men. Then, it was named for a false premise. Now, after more than a century, one of the most common hormone disorders affecting women worldwide has a name that reflects the science.

Blood test detects tumor DNA to guide advanced cancer treatment

A blood test that detects tumor DNA circulating in the bloodstream may help select the most effective treatment options for cancer patients whose tumors have started to spread, according to one of the largest randomized controlled trials of its kind presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026).

Hydrogel breakthrough offers significant advance in type 1 diabetes treatment

Researchers from the University of Geneva (UNIGE) and Geneva University Hospitals (HUG) have reached a significant advance in the fight against type 1 diabetes. Using an innovative hydrogel that supports insulin-producing cells once transplanted into the body, the team successfully regulated blood sugar levels in diabetic mice.
