Mechanism of soil bacteria (Cupriavidus sp. LA-1) for degrading natural pterin and lumazine pigments

Communications Biology
Diverse microbial metabolic mechanisms help maintain the environmental dynamics of natural compounds in biogeochemical cycles. This study revealed the bacterial mechanism for degrading pterin and lumazine compounds, which are natural cofactors and ...

Molybdenum cofactor deficiency: Neuroimaging findings

Radiology Case Reports, 2018
Molybdenum cofactor deficiency is an extremely rare and fatal metabolic disorder that should be considered in the differential diagnosis of hypoxic-ischemic encephalopathy. Magnetic resonance imaging findings are useful in diagnosis. The short-echo-time magnetic resonance spectrum was characterized by a total loss of signal and lipid and lactate peaks.

Crucial involvement of xanthine oxidase in the intracellular signalling networks associated with human myeloid cell function [PDF]

, 2014
Xanthine oxidase (XOD) is an enzyme which plays a central role in purine catabolism by converting hypoxanthine into xanthine and then further into uric acid.

Alogliptin Reduces Oxidative Stress in Cardiomyocytes and Ameliorates Diabetic Cardiomyopathy via the AURKB/NLGN2 Signaling

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Diabetic cardiomyopathy (DCM) is a common complication of diabetes mellitus. This study investigated the effects of alogliptin on DCM and its underlying mechanisms. A DCM model was constructed and treated with alogliptin. Downstream targets of alogliptin were screened using bioinformatics analysis.

Probing a Complex of Cytochromecand Cardiolipin by Magnetic Circular Dichroism Spectroscopy: Implications for the Initial Events in Apoptosis [PDF]

, 2011
Oxidation of cardiolipin (CL) by its complex with cytochrome c (cyt c) plays a crucial role in triggering apoptosis. Through a combination of magnetic circular dichroism spectroscopy and potentiometric titrations, we show that both the ferric and ferrous

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

Pest Management Science, EarlyView.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, EarlyView.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Genetic dissection of cyclic pyranopterin monophosphate biosynthesis in plant mitochondria [PDF]

, 2018
Mitochondria play a key role in the biosynthesis of two metal cofactors, iron-sulfur (FeS) clusters and molybdenum cofactor (Moco). The two pathways intersect at several points, but a scarcity of mutants has hindered studies to better understand these ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

Environmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

The compositional and evolutionary logic of metabolism

, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...
