Inflammatory signals in heart muscle cells linked to atrial fibrillation

Interfering with inflammatory signals produced by heart muscle cells might someday provide novel therapeutic strategies for atrial fibrillation, according to an international team of researchers who have published their findings in the journal Circulation. “Atrial fibrillation is the most common heart arrhythmia, and it is particularly observed in the elderly human population, which is growing

Space-like gravity weakens biochemical signals in muscle formation

Astronauts go through many physiological changes during their time in spaceflight, including lower muscle mass and slower muscle development. Similar symptoms can occur in the muscles of people on Earth’s surface, too. In fact, it could affect everyone to some extent later in life. “Age-related skeletal muscle disorders, such as sarcopenia, are becoming a greater

Like babies, eggs send signals when ‘hungry’

In humans and other mammals, the female reproductive cells – the eggs or oocytes – need nourishment in order to grow and remain fertile. It is known that the egg gets its food from little arm-like feeding tubes (called filopodia) that jut out from tiny cells surrounding the egg and must poke through a thick
