ABSTRACT
The article focuses on a study on knock-out mice to examine the in vivo effect of estrogen-receptor related receptor α (ERRα) on bone. It states that ERRα, which is a member of the nuclear hormone receptor superfamily, acts as a transcription factor and is expressed in ossification zones during development. The study found that in female mice, ERRαKO bones do not age and are resistant to bone loss induced by age or estrogen withdrawal, while no phenotype was observed in the bones of male ERRαKO mice.

    Amyotrophic lateral sclerosis (ALS) is a debilitating and one of the most common adult-onset neurodegenerative diseases with the prevalence of about 5 per 100 000 individuals. It results in the progressive loss of upper and lower motor neurons and leads to gradual muscle weakening ultimately...

    IκBα is an inhibitor of the nuclear transcription factor NF-κB. Binding of IκBα to NF-κB inactivates the transcriptional activity of NF-κB. Expression of IκBα itself is regulated by NF-κB, which provides auto-regulation of this signaling pathway. Here we present a...
