Tetrahydrobiopterin: biochemistry and pathophysiology
Biochemical Journal, 2011 BH4 (6R-L-erythro-5,6,7,8-tetrahydrobiopterin) is an essential cofactor of a set of enzymes that are of central metabolic importance, including four aromatic amino acid hydroxylases, alkylglycerol mono-oxygenase and three NOS (NO synthase) isoenzymes. Consequently, BH4 is present in probably every cell or tissue of higher organisms and plays a key role

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application
Responsive Materials, EarlyView.Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in

Expression of full-length human alkylglycerol monooxygenase and fragments in Escherichia coli
Pteridines, 2013 Alkylglycerol monooxygenase (AGMO; EC 1.14.16.5) is the only enzyme known to cleave the O-alkyl ether bond of alkylglycerols in humans. It is an integral membrane protein with nine predicted transmembrane domains.

Integrative Zoology, EarlyView.Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Insulin Stimulates Tetrahydrobiopterin Synthesis in Mouse Brain Microvascular Endothelial Cells
Pteridines, 1999 We examined the effects of insulin on tetrahydrobiopterin (BH4) synthesis in mouse brain microvascular endothelial cells (MBMECs). Treatment of MBMECs with insulin increased the intracellular BH4 content in a time- and concentration-dependent manner. The

The Emerging Physiological Role of AGMO 10 Years after Its Gene Identification
Life, 2021 The gene encoding alkylglycerol monooxygenase (AGMO) was assigned 10 years ago. So far, AGMO is the only known enzyme capable of catalysing the breakdown of alkylglycerols and lyso-alkylglycerophospholipids. With the knowledge of the genetic information,

Non‐canonical PKG1 regulation in cardiovascular health and disease
British Journal of Pharmacology, EarlyView.It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.
