Abstract
OBJECTIVE Previous studies on overlapping surveillance databases have suggested that statin use was associated with the development of amyotrophic lateral sclerosis (ALS)-like syndrome. However, the association between statin use and ALS incidence has not been clearly elucidated. To further explore this issue, we performed a systemic review and meta-analysis of all available clinical studies on the association between statin use and ALS incidence. METHODS A comprehensive database search on PubMed, Embase, Cochrane Library, and SCOPUS was conducted. We included studies up to January 31, 2020 that fulfilled our inclusion and exclusion criteria. Statin use between the ALS and control groups was collected for the meta-analysis. RESULTS Three case-control studies and 1 cohort study, that related the risk of ALS to statin use, satisfied the inclusion criteria for the meta-analysis. There was no statistically significant difference in statin use between the ALS and control groups (odds ratio, 0.75 [95% confidence interval, 0.53-1.08]). CONCLUSION No definite association was found between statin use and the development of ALS. Further large-scale prospective randomized control studies are necessary to draw definite conclusions.

Abstract
Amyotrophic lateral sclerosis (ALS) is a paralytic, heterogeneous and progressive disease characterized by the degeneration of both upper and lower motor neurons. Several studies about the effects of statins drug on the risk of ALS showed contradictory results and evidence for this is inconclusive. So we aimed to perform a meta-analysis on previous studies to clarify the association between statin use and risk of ALS. The databases including PubMed, Scopus, and Web of science were searched in February 2021 for studies that reported the association between statin use and risk of ALS. The eligible studies had to provide a report on the effect of statin and the incidence of ALS while comparing it to the control group. Articles that had low statin exposure time, the absence of a control group and an unknown number of ALS patients were excluded. The rate ratio and 95% confidence interval (CI) were used for association measures in case-control and cohort studies. After full-text and abstract review, data from 8 studies with a total of 547,622 participants and 13,890 cases of ALS were entered in the present meta-analysis. We combined eight studies using a random-effect model and the RR for statin users among groups was 0.98 (95% CI 0.80-1.20) which indicates no association between statin and incidence of ALS. Also high heterogeneity was detected across the studies (Q value = 26.62, P = .00; I2 = 72.71%). In our meta-analysis study, we found no association between statin use and an increase in ALS incidence. This result is in line with some previous studies and provides strong evidence that denies the possible association between statin uptake and disease induction.

Abstract
INTRODUCTION Converging evidence highlights that lipid metabolism plays a key role in ALS pathophysiology. Dyslipidemia has been described in ALS patients and may be protective but peripheral lipoprotein subclasses have never been studied. MATERIAL AND METHODS We collected sera from 30 ALS patients and 30 gender and age-matched controls. We analyzed 11 distinct lipoprotein subclasses by linear polyacrylamide gel electrophoresis (Lipoprint, Quantimetrix Corporation, USA). We also measured lipoprotein (a), apolipoprotein B, and apolipoprotein E levels. RESULTS ALS patients had significant higher total cholesterol, HDL-cholesterol, and LDL-cholesterol levels than controls (p<0.0001, p=0.0007, and p=0.0065, respectively). The LDL-1 subfraction concentration was higher (1.03±0.41 vs. 0.71±0.28mmol/L; p=0.0006) and the IDL-B subfraction lower (6.5±2% vs. 8.0±2%; p=0.001) in ALS patients than controls. DISCUSSION Our preliminary work confirmed the association between ALS and dyslipidemia. The low IDL-B levels may explain the hepatic steatosis frequently reported in ALS. The high levels of the cholesterol-rich LDL-1 subfraction is consistent with previously reported hypercholesterolemia. CONCLUSION This study describes, for the first time, the distribution of serum lipoproteins in ALS patients, with low IDL-B and high LDL-1 subfraction level.

Screening of Drugs Inhibiting In vitro Oligomerization of Cu/Zn-Superoxide Dismutase with a Mutation Causing Amyotrophic Lateral Sclerosis. Front Mol Biosci 2016; 3:40.

Abstract
Dominant mutations in Cu/Zn-superoxide dismutase (SOD1) gene have been shown to cause a familial form of amyotrophic lateral sclerosis (SOD1-ALS). A major pathological hallmark of this disease is abnormal accumulation of mutant SOD1 oligomers in the affected spinal motor neurons. While no effective therapeutics for SOD1-ALS is currently available, SOD1 oligomerization will be a good target for developing cures of this disease. Recently, we have reproduced the formation of SOD1 oligomers abnormally cross-linked via disulfide bonds in a test tube. Using our in vitro model of SOD1 oligomerization, therefore, we screened 640 FDA-approved drugs for inhibiting the oligomerization of SOD1 proteins, and three effective classes of chemical compounds were identified. Those hit compounds will provide valuable information on the chemical structures for developing a novel drug candidate suppressing the abnormal oligomerization of mutant SOD1 and possibly curing the disease.

Abstract
OBJECTIVE To evaluate the association between statins and the incidence and progression of amyotrophic lateral sclerosis (ALS). METHODS Several electronic databases (PubMed, Embase, and EBSCO) and Chinese databases (CBM, Wanfang, and VIP) were searched for original articles on April 1(st), 2012. Case-control and cohort studies that provide information on the association between statins and ALS were considered eligible for inclusion. A systematic review was conducted to evaluate the association of statins and the incidence and progression of ALS. RESULTS Two case-control studies and one cohort study that relate the risk of ALS to statins satisfied the inclusion criteria for the meta-analysis. The pooled rate ratio of statin use was 0.89 [95% CI, 0.55 to 1.42] for ALS patients versus non-ALS patients. Three cohort studies on the association between statins and the progression of ALS were identified; these suggested that no strong evidence for the statin-ALS progression relationship exists. No cohort studies favor the use of statins on ALS patients. CONCLUSIONS No definite association between statin use and ALS incidence and progression has been found. Existing results are currently inconclusive to make scientifically supported conclusions. Further prospective cohort studies are still needed.
