Partial complementation of pyruvate dehydrogenase deficiency by independently expressed lipoyl and catalytic domains of the dihydrolipoamide acetyltransferase component [PDF]
Two compatible plasmids encoding a hybrid lipoyl domain and a defective pyruvate dehydrogenase (PDH) complex which lacks lipoyl domains, were co-expressed in a strain of Escherichia coli deleted for the PDH complex genes. In vivo complementation between the mutant complexes and the independent lipoyl domains was observed using growth tests in liquid ...

3-Hydroxyisobutyryl-CoA hydrolase involved in isoleucine catabolism regulates triacylglycerol accumulation in Phaeodactylum tricornutum [PDF]
Since methylmalonyl-CoA epimerase appears to be absent in the majority of photosynthetic organisms, including diatoms, (S)-methylmalonyl-CoA, the intermediate of isoleucine (Ile) catabolism, cannot be metabolized to (R)methylmalonyl-CoA then to succinyl ...

Ferroptosis-Related Flavoproteins: Their Function and Stability [PDF]
Ferroptosis has been described recently as an iron-dependent cell death driven by peroxidation of membrane lipids. It is involved in the pathogenesis of a number of diverse diseases.

Mitochondrial alpha-ketoglutarate dehydrogenase complex generates reactive oxygen species [PDF]
Mitochondria-produced reactive oxygen species (ROS) are thought to contribute to cell death caused by a multitude of pathological conditions. The molecular sites of mitochondrial ROS production are not well established but are generally thought to be ...

The natural history of dihydrolipoamide dehydrogenase deficiency in Israel
AbstractDihydrolipoamide dehydrogenase (DLD) deficiency is an ultra‐rare autosomal‐recessive inborn error of metabolism, affecting no less than five mitochondrial multienzyme complexes. With approximately 30 patients reported to date, DLD deficiency was associated with three major clinical presentations: an early‐onset encephalopathic phenotype with ...

Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults. [PDF]
Thiamine (vitamin B1) is an essential nutrient that serves as a cofactor for a number of enzymes, mostly with mitochondrial localization. Some thiamine-dependent enzymes are involved in energy metabolism and biosynthesis of nucleic acids whereas others ...

Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer
ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...

ABSTRACT In a scenario with increasing cases of obesity and diabetes worldwide, branched‐chain amino acids (BCAA) metabolism has become an important factor in the understanding of these pathologies. More recently, its chronic high plasma levels have been postulated, alongside glucose, inflammatory factors, and other molecules, as an important ...
