Salicylic acid is a member of benzoic acid derivatives, a group of compounds which have a backbone of C6C1 consisting of one carboxyl group and one (or more) hydroxyl group(s) attached to the aromatic ring. Salicylic acid is a signaling compound in systemic acquired resistance (SAR). An increased level of salicylic acid is found in the plant after a fungi's attack, which further induces the accumulation of phytoalexins, low molecular weight defense compounds.

In humans, the 2-oxoglutarate-dependent dioxygenases (2-OGDDs) catalyze hydroxylation reactions involved in cell metabolism, the biosynthesis of small molecules, DNA and RNA demethylation, the hypoxic response and the formation of collagen. The reaction is catalyzed by a highly oxidizing ferryl-oxo species produced when the active site non-heme iron engages molecular oxygen. Enzyme activity is specifically stimulated by l-ascorbic acid (ascorbate, vitamin C), an effect not well mimicked by other reducing agents.

Intracerebral hemorrhage (ICH) is the most common subtype of hemorrhagic stroke causing significant morbidity and mortality. Previously clinical treatments for ICH have largely been based on a single pathophysiological perspective, and there remains a lack of curative interventions. Following the rupture of cerebral blood vessels, blood metabolites activate resident immune cells such as microglia and astrocytes, and infiltrate peripheral immune cells, leading to the release of a series of inflammatory mediators.

The utilization of cyanobacteria toxin-producing blooms for metal ions adsorption has garnered significant attention over the last decade. This study investigates the efficacy of dead cells from Microcystis aeruginosa blooms, collected from agricultural drainage water reservoir, in removing of cadmium, lead, and zinc ions from aqueous solutions, and simultaneously addressing the mitigation of toxin-producing M. aeruginosa bloom.

This study is the first to use synthetic biological omics technology to analyze the molecular mechanism underlying deep degradation of TNT, to construct an artificial transformation system to create engineered Escherichia coli bacteria, and to use Bacillus subtilis as an expression host to explore the mechanism driving the reshaping of the deep degradation platform on microecology. Nitroreductase family protein, 2-oxoacid:acceptor oxidoreductase, NADPH-cytochrome P450 reductase, monooxygenase, ring-cleaving dioxygenase, and RraA family protein significantly participated in the reduction-hydroxylation-ring opening cleavage of TNT, achieving deep transformation of TNT to produce pyruvic acid and other products that entered the cellular metabolic cycle. The key toxic metabolic pathways of TNT, 2,4-diamino-6-nitrotoluene, 2,4,6-triaminotoluene, and 2,4,6-trihydroxytoluene are pantothenate and CoA biosynthesis.
