Shikimate and Phenylalanine Biosynthesis in the Green Lineage

open access: yesFrontiers in Plant Science, 2013
The shikimate pathway provides carbon skeletons for the aromatic amino acids l-tryptophan, l-phenylalanine, and l-tyrosine. It is a high flux bearing pathway and it has been estimated that greater than 30% of all fixed carbon is directed through this ...

Asymmetric Strategies for the Synthesis of Enantiopure α‐/β‐/γ‐Thio‐Carboxylic Acids Bearing a Stereocentre at CS Bond

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Enantioenriched α‐/β‐/γ‐thiocarboxylic acids featuring C–S chirality are valuable targets in organic synthesis. This review outlines recent progress in their asymmetric synthesis, including chiral pool approaches, metal‐ /organo‐catalysis, and emerging biocatalytic strategies. Enantiomerically pure α‐/β‐/γ‐thiocarboxylic acids bearing a stereocentre at

Therapeutic implication of L-phenylalanine aggregation mechanism and its modulation by D-phenylalanine in phenylketonuria

open access: yesScientific Reports, 2014
Self-assembly of phenylalanine is linked to amyloid formation toxicity in phenylketonuria disease. We are demonstrating that L-phenylalanine self-assembles to amyloid fibrils at varying experimental conditions and transforms to a gel state at saturated ...

Tryptophan Metabolite Indole‐3‐Aldehyde Induces AhR and c‐MYC Degradation to Promote Tumor Immunogenicity

open access: yesAdvanced Science, EarlyView.
Tryptophan metabolite Indole‐3‐aldehyde (I3A) downregulates cytosolic AhR and p‐ERK/c‐MYC proteins, together enhancing STAT3 phosphorylation and tumor immunogenicity. Overexpression of the Trp metabolic enzyme interleukin‐4‐induced gene‐1 (IL4I1) in tumor cells increases intracellular levels of I3A and enhances tumor immunogenicity.

Immune activation and inflammation increase the plasma phenylalanine-to-tyrosine ratio

open access: yesPteridines, 2013
The proinflammatory cytokine interferon (IFN) γ activates GTP-cyclohydrolase I. In turn, the production of neopterin in human monocytic cells and of 5,6,7,8-tetrahydrobiopterin (BH4) in other human cells and cells of other species is markedly upregulated.

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

open access: yesAdvanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

Cathepsin K Aggravates Pulmonary Fibrosis Through Promoting Fibroblast Glutamine Metabolism and Collagen Synthesis

open access: yesAdvanced Science, EarlyView.
CTSK plays a critical role in pulmonary fibrosis. Excessive CTSK accumulation interacts with SNX9 to enhance TGF‐β1‐induced SMAD3 activation and GLS1 expression in fibroblasts, driving glutamine metabolism for collagen biosynthesis and exacerbating pulmonary fibrosis.

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

open access: yesAdvanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.
