A connection between senescence and stem cells caused by a breast cancer-initiating protein

Researchers from the Spanish National Cancer Research Centre (CNIO) and the IDIBELL, led by Eva González-Suárez at the CNIO, have found that the hyperactivation of the RANK pathway plays a double function in breast cells: in the early stages of cancer, it activates senescence, which has a protective effect and delays the appearance of tumours; in more advanced stages, RANK-induced senescence favours the accumulation of stem cells, which promotes tumour growth and aggressiveness. ....

In Amyotrophic Lateral Sclerosis (ALS), the progressive death of neurons that control body movement leads to paralysis of muscles in the limbs and gradually of the whole body, which ultimately makes it impossible to breathe. ALS is currently untreatable, and its cause is unknown.
It is known, however, that in 10% of affected individuals there is a strong genetic component, which causes the disease to occur in several members of a single family. In about half of these cases of familial ALS, the origin lies in a gene called C9ORF72. But why do mutations in this gene kill motor neurons? ....
