Cuproptosis
A distinct form of regulated cell death caused by excess intracellular copper binding to lipoylated proteins in the TCA cycle, first characterized by Tsvetkov et al. in Science (2022). Unlike ferroptosis (iron-dependent lipid peroxidation) or apoptosis (caspase-dependen…

Dysbiosis
Disruption of the normal composition and metabolic function of microbial communities, particularly the gut microbiome. In the metallomics context, dysbiosis is both a consequence of metal toxicity and an amplifier of further disease -- creating vicious cycles where meta…

Indoxyl Sulfate
Indoxyl sulfate (IS) is a protein-bound uremic toxin produced through a two-step process: gut bacteria convert dietary tryptophan to indole, which is then absorbed and sulfated by hepatic sulfotransferases (SULT1A1). IS exemplifies how dysbiosis-driven metabolite overpr…

Metalloregulator
Protein-based transcription factors that sense intracellular metal concentrations and regulate gene expression accordingly. Metalloregulators are the decision-making layer of bacterial metal homeostasis -- they read the labile metal pool, determine whether a specific me…

Mitochondrial Dysfunction
Mitochondrial dysfunction refers to the impairment of mitochondrial energy production, redox balance, and signaling functions. Mitochondria are the primary targets of heavy metal toxicity in human cells, and they are also the organelles most dependent on metal cofactors…

sRNA (Small Regulatory RNA)
Small regulatory RNAs (sRNAs) are non-coding RNA molecules, typically 50-500 nucleotides long, that regulate gene expression post-transcriptionally in bacteria. In the context of metal biology and microbial pathogenesis, sRNAs serve as rapid-response coordinators that h…

Taurine
Taurine (2-aminoethanesulfonic acid) is a sulfur-containing amino acid abundant in bile, heart, brain, and retina. Its primary metabolic role is bile acid conjugation — taurocholate and taurochenodeoxycholate are the taurine-conjugated primary bile acids that BSH-produc…
