A population-based study found that patients with estrogen receptor-positive breast cancer who experienced hot flashes while on adjuvant hormone therapy had worse outcomes and a higher risk of early treatment discontinuation. The study suggests that managing side effects may not be enough to prevent treatment discontinuation, highlight...
Researchers found higher AR signaling and better response rates for female patients treated with BRAF/MEK inhibitors. Blocking the AR improved response to BRAF/MEK targeted therapy in both males and females.
Menopause is often perceived as a hormone deficiency, but experts argue this can lead to negative expectations. Instead, a more nuanced approach emphasizes the positive aspects of menopause, such as freedom from menstruation and reduced symptoms. Normalizing ageing and celebrating women's strengths can also improve experiences.
A new study published in Science Translational Medicine reveals that consecutive molecular modifications of the androgen receptor can contribute to drug resistance in prostate cancer. Researchers identified a potential treatment approach using an ACK1 inhibitor to block this resistance.
A University of Jyväskylä study found that menopausal women's ability to use fat as an energy source is not impaired by estrogen levels or menopause. Women who burned more fat during exercise had higher fitness and physical activity levels, while those with better glucose tolerance did not necessarily burn more fat.
