Identification of Metabolic Intermediates in Microbial Degradation of Chrysene by Armillaria sp. F022

open access: yesIndonesian Journal of Biotechnology, 2010
To degrade chrysene, a polycyclic aromatic hydrocarbon (PAH), Armillaria sp. F022, a fungus collected from a soil, was used. Maximal degradation (77%) was obtained when Armillaria sp.

Engineering Osteoimmune Responses with Functionalized Orthopedic Implants for Post‐Operative Osteosarcoma Treatment

open access: yesAdvanced Science, EarlyView.
Osteosarcoma is the most common primary bone tumor with limited treatment options and a terrible prognosis. This review provides a comprehensive summary of the recent development of osteoimmunomodulatory implants for post‐operative osteosarcoma treatment, of which the potential utility in evoking durable anti‐osteosarcoma immunity and accelerating bone

Metabolic Origin, Role and Fate of the Denaturant Guanidine

open access: yesMicrobial Biotechnology
Despite its unusual structure and detrimental role as a chaotropic guanidinium ion, guanidine [HNC(NH2)2] exists as a genuine metabolite in many microbes, and its negative effects are mitigated by specific exporters. The metabolic origin of this molecule

Characterization and evaluation of catechol oxygenases by twelve bacteria, isolated from oil contaminated soils in Malaysia [PDF]

open access: yesBiological Journal of Microorganism, 2017
Introduction: Catechol is a common intermediate compound in aromatic degradation process. Some microorganisms have this potentiality to degrade aromatic hydrocarbons by catechol dioxygenases to less toxic compounds with ability of entering the ...

IL4I1⁺ Macrophages and TDO2⁺ Myofibroblasts Drive AhR‐Mediated Immunosuppression and Ferroptosis Resistance in Solid Predominant Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
Solid predominant lung adenocarcinoma exhibits an immune‐excluded, ferroptosis‐resistant niche enriched with IL4I1⁺ TAMs and TDO2⁺ myCAFs. Spatial and multi‐omics analyses reveal AhR‐driven crosstalk that promotes T cell exhaustion and therapy resistance. Blocking AhR with CH‐223191 restores ferroptosis sensitivity, and its combination with ferroptosis

The S. pombe histone H2A dioxygenase Ofd2 regulates gene expression during hypoxia.

open access: yesPLoS ONE, 2012
Post-translational modification of histone proteins are known to play an important role in regulating chromatin structure. In an effort to find additional histone modifications we set out to screen enzymes of the 2-oxoglutarate and Fe(II)-dependent (2-OG-

Exogenous Tryptophan Promotes Cutaneous Wound Healing of Chronically Stressed Mice through Inhibition of TNF-α and IDO Activation. [PDF]

open access: yesPLoS ONE, 2015
Stress prolongs the inflammatory response compromising the dermal reconstruction and wound closure. Acute stress-induced inflammation increases indoleamine 2, 3-dioxygenase-stimulated tryptophan catabolism.

Indoleamine 2,3-dioxygenase is a critical resistance mechanism in antitumor T cell immunotherapy targeting CTLA-4

open access: yesJournal of Experimental Medicine, 2013
Indoleamine 2,3-dioxygenase suppresses infiltration and accumulation of tumor-reactive T cells in the context of anti–CTLA-4 immunotherapy and attenuates the anti-tumor efficacy.

Fluorinated Carnitine Derivatives as Tools to Visualise Carnitine Transport and Metabolism

open access: yesAdvanced Science, EarlyView.
Fluorinated carnitines, fluoromethyl carnitine (FMC) and [18F]fluoromethyl carnitine ([18F]FMC), are synthesised and established as powerful probes to interrogate carnitine biology. The multimodal detection facilitated by fluorine labelling, including 19F NMR, mass spectrometry, and positron emission tomography imaging, allowed for visualisation of ...
