Metal exposure is an intriguing potential culprit in the cause of sporadic amyotrophic lateral sclerosis (ALS). Lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As) are singled out among the ten chemicals of major public health concern by the World Health Organisation. There are numerous case reports and case-control studies linking those metals to an ALS phenotype. Additionally, some studies have demonstrated higher levels of these metals in the blood, cerebrospinal fluid, urine, or spinal cords of patients with ALS compared to controls. Recently, it has been proposed that the interaction b

…GemPharmatech (GPT) generated the GPT hSOD1 G93A transgenic mouse strain to recapitulate ALS-like phenotypes in an animal model, in support of medical research and drug development. The hSOD1 G93A mouse model carries the G93A mutation in human SOD1 gene, which is widely expressed in mice. We observed an apparent body weight decrease in 25-week-old mice. We further performed a range of behavioral tests to identify the disease onset timing in GPT hSOD1 G93A mouse model,

Oxidative stress and neuroinflammation are crucial phenomena in the pathogenesis of Alzheimer disease (AD). Oxotremorine-M (Oxo), a non-selective muscarinic acetylcholine receptors agonist, exerts neurotrophic functions in primary neurons and modulates oxidative stress and neuroinflammation phenomena in rat brain. Based on this, our study investigates Oxo positive effects on differentiated SH-SY5Y neuroblastoma cells, revealing that Oxo treatment a) enhances cell survival, b) increases neurite length and c) upregulates HSP70 and pHSF1 expression. Moreover, Oxo counteracts tert–Butyl hydroperox

Ageing has been defined as a gradual functional decline with a progressive physiological integrity loss, increasing the organism’s vulnerability to death. Otherwise, this described deterioration is the major risk factor for most current human pathologies, including neurodegenerative diseases, cancer, cardiovascular disorders, and diabetes. However, in the last decades, non-pharmacological treatments like physical exercise have provided general health benefits against ageing decline. In this study, we aim to analyze how lifestyle factors such as physical exercise can modify the molecular expres

Six of 19 patients (31.6%) with sporadic ALS had elevated plasma misfolded SOD1 protein levels. In sporadic A
