Imaging identifies breast cancer patients unlikely to benefit from hormone therapy
Hormone therapy can be very effective for so-called estrogen receptor-positive breast cancer. But it only works for a little more than half of women who receive the treatment. In a small study, researchers at Washington University School of Medicine in St. Louis found that women whose tumors did not respond to a one-day estrogen challenge did not benefit from hormone therapy. The findings could help doctors choose treatments most likely to help their patients. (2021-02-02)

Bonobos, chimpanzees, and oxytocin
Kyoto University researchers analyze the effects of the hormone oxytocin in our closest primate cousins, bonobos and chimpanzees by tracking their eye movement -- a important indicator of social interaction. Similar to other mammals, oxytocin increases eye contact in bonobos. However, the opposite effect is observed in chimpanzees. Therefore, oxytocin could play a modulating role in the social evolution of the two species. (2021-01-20)

Silkworm's brain determines diapause by thermal information
Silkworms (Bombyx mori) were found to lay diapause eggs at 25°C and non-diapause eggs at 15°C. Females were observed to determine whether to lay diapause eggs or not according to thermal information received by the embryonic Bombyx TRPA1 ortholog (BmTRPA1). In this study scientists at Shinshu University et al. have elucidated that the neuropeptide corazonin regulates the release of the diapause hormone. (2020-12-21)

The neurobiology of thirst: The neural mechanisms that control hydration
Scientists at the Tokyo Institute of Technology (Tokyo Tech) provide deeper insights into neural thirst control. Their study published recently in Nature Communications indicates that cholecystokinin-mediated water-intake suppression is controlled by two neuronal 'thirst-suppressing' sub-populations in the subfornical organ in the brain; one population is persistently activated by excessive water levels, and the other, transiently after drinking water. (2020-11-26)

Study: gut hormones' regulation of fat production abnormal in obesity, fatty liver disease
Gut hormones play an important role in regulating fat production in the body. One key hormone, released a few hours after eating, turns off fat production by regulating gene expression in the liver, but this regulation is abnormal in obesity, researchers at the University of Illinois Urbana-Champaign found in a new study. (2020-11-24)

A hormone that can suppress food intake and increase the feeling of fullness in mice has shown similar results in humans and non-human primates, says a new study published today in eLife. (2020-11-24)

Early weight gain in children linked to ability to produce the hormone leptin
The brain controls weight by measuring levels of leptin in the blood, which is released by fat cells. In adults, leptin treatments have so far proved ineffective at treating obesity. New genetics research by scientists at the University of Copenhagen suggests that leptin plays a stronger role in controlling the weight of children than in adults. (2020-11-23)
