New insights into immune cells in cancer immunotherapy: from epigenetic modification, metabolic modulation to cell communication

open access: yesMedComm, Volume 5, Issue 6, June 2024.
Relationships between immune cell metabolism, epigenetics modulation, and cancer immunotherapy clinical efficiency. Epigenetic regulation (including DNA methylation, RNA methylation, histone modification, and chromatin remodeling) of immune cells can influence the differentiation and activity of immune cells, while metabolic status influences the ...

Tailoring modifications in labrenzin synthesis: a‐la‐carte production of pathway intermediates

open access: yesMicrobial Biotechnology, Volume 17, Issue 1, January 2024.
In this work, we study the role of tailoring enzymes from the lab gene cluster responsible for methylation and hydroxylation of labrenzin, a pederin‐family molecule. By expressing them heterologously, we managed to produce a spectrum of differently tailored labrenzin analogs in Labrenzia sp. PHM005.

A novel gamma-N-methylaminobutyrate demethylating oxidase involved in catabolism of the tobacco alkaloid nicotine by Arthrobacter nicotinovorans pAO1.

open access: yesEuropean Journal of Biochemistry, 2004
Nicotine catabolism, linked in Arthrobacter nicotinovorans to the presence of the megaplasmid pAO1, leads to the formation of gamma-N-methylaminobutyrate from the pyrrolidine ring of the alkaloid.

Interactions of substrates with a purified 4-methoxybenzoate monooxygenase system (O-demethylating) from Pseudomonas putida.

open access: yesEuropean Journal of Biochemistry, 1973
The interaction of substrates with a 4-methoxybenzoate O-demethylating enzyme system was studied by use of crude cell-free extracts and also by the purified enzyme system.

Comparative genomics of thiol oxidoreductases reveals widespread and essential functions of thiol-based redox control of cellular processes.

open access: yesAntioxidants and Redox Signaling, 2012
AIMS Redox regulation of cellular processes is an important mechanism that operates in organisms from bacteria to mammals. Much of the redox control is provided by thiol oxidoreductases: proteins that employ cysteine residues for redox catalysis.

Epigenetics of SFRP1: The Dual Roles in Human Cancers

open access: yesCancers, 2020
Secreted frizzled-related protein 1 (SFRP1) is a gene that belongs to the secreted glycoprotein SFRP family. SFRP1 has been classified as a tumor suppressor gene due to the loss of expression in various human cancers, which is mainly attributed by ...

Banana skin: a novel material for a low-cost production of laccase [PDF]

open access: yesarXiv, 2008
Laccases (benzenodiol: oxygen oxidoreductases; EC 1.10.3.2) are multicopper oxidases of wide substrate specificity mainly found in white-rot fungi, which are the only microorganisms able to degrade the whole wood components, but they are also expressed in bacteria and higher plants. Laccases are used currently in biotechnological processes because this

Multi-scale Molecular Simulations on Respiratory Complex I [PDF]

open access: yesChemical Biology No. 5 (2018), 2019
Complex I (NADH:ubiquinone oxidoreductase) is a redox-driven proton pump that powers synthesis of adenosine triphosphate (ATP) and active transport in most organisms. This gigantic enzyme reduces quinone (Q) to quinol (QH2) in its hydrophilic domain, and transduces the released free energy into pumping of protons across its membrane domain, up to ca ...

Inhibition of DNA methylation and reactivation of silenced genes by zebularine.

open access: yesJournal of the National Cancer Institute, 2003
BACKGROUND Gene silencing by abnormal methylation of promoter regions of regulatory genes is commonly associated with cancer. Silenced tumor suppressor genes are obvious targets for reactivation by methylation inhibitors such as 5-azacytidine (5-Aza-CR ...
