Summary: The study found that isopropanol can solubilize VLCFAs in aqueous medium by facilitating the formation of the VLCFA/albumin complex, enabling the examination of peroxisome's role in VLCFAs uptake and metabolism in CHO cells. Wild-type CHO cells showed extensive uptake and oxidative degradation of saturated VLCFAs, while peroxisome-deficient cells had limited uptake and lacked oxidative metabolism. Both cell types showed extensive uptake and acylation of monounsaturated VLCFAs, but only wild-type cells exhibited oxidative metabolism. This suggests that peroxisome deficiency limits intracellular S-VLCFAs by halting uptake, leading to a loss of clearance ability of extracellular S-VLCFAs.

Summary: Beta-oxidation is an important metabolic process that breaks down fatty acids for energy production. Peroxisomal beta-oxidation plays a crucial role in the oxidative metabolism of very long-chain fatty acids and its importance in disease treatment should not be overlooked.

Summary: ABC transporters play important roles in peroxisomes and are involved in various physiological processes, including lipid transport and disease development. Defects in ABCD1 and ABCD3 can lead to two common genetic disorders, with peroxisomal ABC transporters also playing crucial roles in cell signaling and cancer.

Summary: Aromatic compounds derived from renewable sources such as plant biomass are of interest for various industries. The fungus Aspergillus niger can release valuable compounds like ferulic acid and p-coumaric acid from plant biomass. Genes involved in the degradation of hydroxycinnamic acids have been identified through whole-genome transcriptomic analysis in A. niger, providing insights into metabolic pathways and potential applications in the degradation of aromatic compounds.

Summary: One of the major functions of peroxisomes in mammals is to oxidize very long-chain fatty acids (VLCFAs), which if accumulated due to genetic defects in peroxisomal β-oxidation, can lead to various health problems. The biological effect of extracellular VLCFAs was characterized using a solubilizing technique in peroxisome-deficient CHO cells, PC12 cells, and IFRS1 cells. The study found that C20:0 fatty acid was the most toxic among the tested C16-C26 FAs, causing apoptosis in cells. Peroxisomes play a crucial role in detoxifying apoptotic VLCFAs by preventing their accumulation.

Summary: Adrenoleukodystrophy (ALD) is an inherited disorder characterized by accumulation of very long-chain fatty acids. We investigated nervonic acid as a potential therapy for ALD and found that it can reverse lipid accumulation and protect cells from oxidative damage. This suggests that nervonic acid could be a therapeutic option for ALD.

Summary: X-linked adrenoleukodystrophy (XALD) is a genetic neurologic disorder caused by mutations in the ABCD1 gene, presenting with diverse phenotypes and limited therapeutic options. A study identified a potential therapeutic benefit of the anti-hypertensive drug irbesartan in reducing VLCFA levels in XALD patients, but further validation is needed.
