MetabolomicsMulti-omics reveals the response and adaptation of Acidithiobacillus ferrooxidans BY-3 under arsenic stress
Acidithiobacillus ferrooxidans exhibits arsenic resistance and plays a significant role in biometallurgy and sulfur cycling within ecosystems. This study employed integrated transcriptomic, proteomic, and metabolomic analyses to investigate the molecular response mechanisms of Acidithiobacillus ferr...

MetabolomicsArsenic induces metabolome remodeling in mature human adipocytes
Human lifetime exposure to arsenic through drinking water, food supply or industrial pollution leads to its accumulation in many organs such as liver, kidneys, lungs or pancreas but also adipose tissue. Recently, population-based studies revealed the association between arsenic exposure and the deve...

MetabolomicsArsenic-induced enhancement of diazotrophic recruitment and nitrogen fixation in Pteris vittata rhizosphere
Heavy metal contamination poses an escalating global challenge to soil ecosystems. Hyperaccumulators play a crucial role in environmental remediation and resource recovery. The enrichment of diazotrophs and resulting nitrogen accumulation promoted hyperaccumulator growth and facilitated phytoremedia...

TranscriptomicsPrenatal Arsenic Exposure Alters Gene Expression in the Adult Liver to a Proinflammatory State Contributing to Accelerated Atherosclerosis
Developmental exposures play a role in adult onset chronic disease. The mechanisms by which environmental toxicants alter developmental processes predisposing individuals to chronic disease are not understood. arsenic exposure via drinking water causes cancer and cardiovascular disease. Transplacent...

TranscriptomicsComparative transcriptome analysis of transporters, phytohormone and lipid metabolism pathways in response to arsenic stress in rice (Oryza Sativa L.)
Arsenic (As) is a carcinogenic metalloid that is a contaminant widely polluting rice paddy soils around the world. In order to gain better insight into molecular mechanism of rice exposed to As(III) stress, we used next-generation sequencing technology to acquire global transcriptome alteration and ...

TranscriptomicsGenomic responses to arsenic in Synechocystis
Arsenic is an ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [AsIII] and arsenate [AsV]. Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by the arsBHC operon and two additional arsenate reductases encoded by the arsI1 and ars...
