Ageing is exacerbated by alterations of stem cell circadian rhythm

Stem cell functions continue to be governed by day and night cycles (circadian rhythms) during ageing, but their rhythms become devoted to tissue repair and not to the maintenance of tissue tone.

The two studies published in Cell and headed by Salvador Aznar Benitah at IRB Barcelona reject the scientific dogma associating ageing with the loss of stem cell circadian rhythm.

A low-calorie diet delays alterations in the rhythmic functions of stem cells and slows down ageing.

Excess muscle glycogen in mice impairs endurance exercise performance

A study published in Cell Metabolism by IRB Barcelona scientists turns long-standing assumptions about glycogen biology on their head.

The results may explain the muscular defects of patients with glycogen storage disease XV.
