Estrogen

Estrogens are a family of related molecules that stimulate the development and maintenance of female characteristics and sexual reproduction.

What is Estrogen?

Estrogens (also called Oestrogens) are steroid compounds that are important for development and functioning of females of the species. They are named so because they play an important role in the estrous cycle. Their name comes from estrus/oistros (period of fertility for female mammals) + gen/gonos = to generate.

Early camizestrant therapy keeps advanced breast cancer in check

Switching to camizestrant, a next-generation oral SERD, significantly prolongs progression-free survival and maintains quality of life in patients with ESR1-mutated, hormone receptor-positive advanced breast cancer. The proactive, biomarker-guided approach allows earlier intervention and may redefine standard care.

Treatment switching guided by liquid biopsy results improves outcomes in advanced breast cancer

A large prospective, randomized clinical trial in patients with advanced breast cancer has found that the use of liquid biopsy blood tests for early detection of a treatment-resistance mutation, followed by a switch to a new type of treatment, substantially extends the period of tumor control compared to standard care.

Endurance training leads to significant drops in vascular resistance and diastolic blood pressure

Eight months of supervised marathon training in Finnish adults led to moderate reductions in peripheral diastolic blood pressure, systemic vascular resistance, and extracellular water volume. Central (aortic) blood pressure showed a non-significant decline, highlighting the specific impact of exercise on vascular health.

US hospitals see rising complications in patients with takotsubo cardiomyopathy

A large US study found that takotsubo cardiomyopathy is associated with high in-hospital mortality and serious cardiovascular complications, with no improvements in outcomes over five years. Mortality is more than double in men compared to women, and risk factors include age, race, and hospital characteristics.

Breast tissue changes could predict aggressive cancer and poor survival rates

Researchers at the National Institutes of Health (NIH) have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, that is associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer.

Study shows brain estrogen directly regulates appetite in mice

Researchers in Japan found that estrogen produced within the brain, called neuroestrogen, suppresses appetite and reduces body weight in mice by enhancing MC4R expression. The study also showed that neuroestrogen boosts leptin sensitivity, suggesting new targets for obesity treatment.
