Hormone

The role of gut bacteria in the progression of prostate cancer has been highlighted in a new study showing how the microbiome can influence hormone metabolism, which subsequently amplifies tumor growth and disrupts certain hormone treatments.

A new study has highlighted the gut-brain link between social behavior and gut microbes in mice, showing how a lack of certain gut bacteria can increase levels of a hormone that activates a part of the brain that contributes to antisocial activities.

A study tracking testosterone in hospitalized COVID-19 patients found a link between low levels in men and severe disease outcomes. The research offers important clues as to why men seem to be at greater risk of death due to coronavirus than women.

Exercise can be a means to an end, namely better health. Now scientists at USC have studied a hormone that the human body releases during exercise, and found that administering it to even elderly mice improves their fitness and overall health.

New findings from a team of Australian scientists suggest increased exposure to testosterone during pregnancy, triggered by a vitamin D deficiency, may be one of the causal factors explaining why autism spectrum disorder is more common in boys.

Dormant tumor cells can sit quietly for years but exactly what reactivates these sleeping cancer cells is unknown. A new study is offering a novel hypothesis, suggesting stress hormones can trigger a chain of events that reawaken these dormant cells.

A new study has discovered a previously unknown mechanism by which a hormone released from the gut hours after eating effectively switches off the body’s fat production processes, and found this mechanism is defective in those with fatty liver disease.

An intriguing new animal study is suggesting a hunger-regulating hormone secreted from the stomach may also influence memory and cognitive function. The study builds on a growing body of research into gut-brain communication via the vagus nerve.

New data suggests testosterone therapy may be a helpful treatment for some men suffering from obesity. The research finds long-term testosterone therapy can, in some cases, be as effective as bariatric surgery in morbidly obese subjects.

Compelling new research, studying zebrafish fights, is suggesting the fight-or-flight mechanism is modulated by a hormone that regulates appetite. And when the fish are starving this mechanism is triggered, helping them fight significantly longer.

Scientists recently discovered the liver releases a hormone to suppress consumption of sweet foods once a person has consumed high volumes of sugar. A new study has homed in on exactly how this mechanism works, and where in the brain it takes place.

Researchers have developed a novel technique that combines two diabetes drugs into a single injection. Previously these compounds required separate injections, creating a barrier for treatment that led to few diabetics embracing the novel therapy.
