Protein overexpression at heart of heart failure

...s, e.g.: the familial forms. Intracellular [Ca2+]i homeostasis is essential for normal cardiac function and integrity, and dysregulation of [Ca2+]i is a hallmark of advanced heart failure.2 The primary trigger for cardiac [Ca2+]i transients is calcium entry through the pore subunit of the voltage-dependent L-typ...

Just like us, social stress prompts hamsters to overeat, gain weight

...predictable events, causing greater alterations in homeostasis and thus increased stress," the authors wrote. "In addition, previous research suggests that unpredictable events cause greater activation in brain regions responsible for fear and anxiety in laboratory rats and reduction in immune function compared ...

Regenerating worms help elucidate stem cell biology

...petent to restore aged differentiated cells during homeostasis as well as missing tissues after amputation. Unlike what's been thought about piwi for some time, which is that it was required to maintain the stem cell, we think that's not happening here. The stem cells are being maintained by another mechanism...

Iron exporter revealed that may explain common human disorder

...n patients with the disease, perturbations in iron homeostasis result from a failure to control iron export through ferroportin, leading to increased iron release from macrophages and enhanced intestinal absorption. Indeed, patients with the disease exhibit a deficiency of hepcidin, a hormone that binds ferropor...
