Background: The pathological mechanisms underlying peroxisomal biogenesis disorders (PBD) are not fully understood and the available therapies are not sufficient. This stresses the importance of identifying biochemical markers that reflect the extent of peroxisomal dysfunction in plasma of PBD patients.
Methods: Very long chain fatty acids VLCFAs, Phytanic acid, inflammatory markers: tumor necrosis-alpha, interleukin-6, and interleukin-2 (TNF-alpha, IL-6, and IL-2), lipid peroxidation parameter malonedialdhyde (MDA), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and catalase activity were measured.
Results: Significant increases in LDL-C, VLCFAs (C26:0, C26:0/C22:0 and C24:0/C22:0), Phytanic acid, MDA, and Catalase were observed along with significant decreases in Plasmalogen and HDL-C level. No significant difference could be found between male and female patients regarding the biochemical parameters. Both cholesterol and triglycerides showed no significant difference between patients and controls. The characteristic curve (ROC) showed that VLCFAs were the most significant diagnostic markers for PBD followed by TNF-alpha, IL2, IL6, MDA, and plasmalogens.
Conclusions: PBD patients have impaired anti-oxidative defense together with increased inflammatory markers. We provide biomarkers that could guide therapies and prevention strategies. Based on our results we suggest clinical trials to investigate the role of dietary supplementation of antioxidants such as vitamin C and E as an adjuvant therapy for PBD patients.

Cisplatin is widely used for the treatment of solid tumors and its antitumor effects are well established. However, a known complication of cisplatin administration is acute kidney injury (AKI). In this study, we examined the role of TEA domain family member 1 (TEAD1) in the pathogenesis of cisplatin-induced AKI.

Background: Peroxisome biogenesis disorders (PBD) affect multiple organ systems. It is characterized by neurological dysfunction, hypotonia, ocular anomalies, craniofacial abnormalities, and absence of peroxisomes in fibroblasts. PBDs are associated with mutations in any of fourteen different genes, which are involved in peroxisome biogenesis.

Objective: Anxiety and depression-like symptoms occur in the early stages of Alzheimer's disease. Hippocampal Sirtuin 1 (SIRT1) signaling mediates anxiety- and depression-like behavior. Exercise training improves anxiety and depression-like behavior in various disease models, such as the rat chronic restraint stress model, rat model of posttraumatic stress disorder, and rat model of fetal alcohol spectrum disorders.

The PEX1/PEX6 AAA-ATPase is required for the biogenesis and maintenance of peroxisomes. Mutations in and disrupt peroxisomal matrix protein import and are the leading cause of Peroxisome Biogenesis Disorders (PBDs). The most common disease-causing mutation in PEX1 is the PEX1 allele, which results in a reduction of peroxisomal protein import.
