The antioxidant enzyme superoxide dismutase 1 (SOD1) is a critical player of the antioxidative defense whose activity is altered in several chronic diseases, including amyotrophic lateral sclerosis. However, how oxidative insult affects muscle homeostasis remains unclear. This study addresses the role of oxidative stress on muscle homeostasis and function(More)
Reelin is an extracellular matrix protein that plays a pivotal role in development of the central nervous system. Reelin is also expressed in the adult brain, notably in the cerebral cortex, where it might play a role in synaptic plasticity. The mechanism of action of reelin at the molecular level has been the subject of several hypotheses. Here we show(More)
Muscle regeneration following injury is characterized by myonecrosis accompanied by local inflammation, activation of satellite cells, and repair of injured fibers. The resolution of the inflammatory response is necessary to proceed toward muscle repair, since persistence of inflammation often renders the damaged muscle incapable of sustaining efficient(More)
AIM To evaluate the potential interference of trunk fat (TF) mass on metabolic and skeletal metabolism. METHODS In this cross-sectional study, 340 obese women (mean age: 44.8 ± 14 years; body mass index: 36.0 ± 5.9 kg/m(2)) were included. Patients were evaluated for serum vitamin D, osteocalcin (OSCA), inflammatory markers, lipids, glucose and insulin(More)
The Androgen Receptor (AR) pathway is involved in the development of skeletal muscle but the molecular basis of androgen-related myogenic enhancement is still unclear. We have investigated AR expression and localization during myoblasts-myotubes differentiation in skeletal muscle cell line C2C12. AR expression increases during proliferation and commitment(More)
The belief that obesity is protective against osteoporosis has recently been revised. In fact, the latest epidemiologic and clinical studies show that a high level of fat mass, but also reduced muscle mass, might be a risk factor for osteoporosis and fragility fractures. Furthermore, increasing evidence seems to indicate that different components such as(More)
AIM Several chronic metabolic alterations are present in obese subjects. While it is well known about the detrimental effect of abdominal adipose tissue on chronic metabolic clinical condition, less is known on the role of lean mass in obese subjects. Thus, the aim of our study was to evaluate the potential correlation of muscle mass, metabolic condition(More)
Acidic tumor microenvironment and Wnt/β-catenin pathway activation have been recognized as two crucial events associated with the initiation and progression of cancer. The aim of this study was to clarify the molecular mechanisms underlying the anti-proliferative effects of atrial natriuretic peptide (ANP) as well as to investigate the relationship between(More)
In Vertebrates, all genes coding for ribosomal proteins, as well as those for other proteins implicated in the production and function of translation machinery, are regulated by mitogenic and nutritional stimuli, at the translational level. A cis-regulatory element necessary for this regulation is the typical 5'UTR, common to all ribosomal protein mRNAs,(More)
Mycobacterium tuberculosis (MTB) colony morphology was associated to the pathogen's virulence. We isolated a new MTB H37Rv smooth colony, which only appeared following human macrophages (MDM) infection. The new phenotype was Alcohol-Acid resistant, but devoid of a covering capsule and biofilm defective. We ascertained that there were no deletions in the(More)
