Cadmium (Cd) and chromium (Cr) are frequently encountered toxicants, while iron (Fe) plays a crucial role in bacterial survival under conditions of heavy metal stress. However, intracellular Fe ion depletion by heavy metals leads to a state of Fe starvation. Therefore, it is imperative to investigate the mechanism through which bacteria maintain a balance between heavy metal detoxification and Fe homeostasis. This study demonstrates Cd(II) immobilization and Cr(VI) reduction abilities of <i>Sten ...[more]

Drivers of metallothionein-mediated detoxification of cadmium in C.elegans

Project description:Cadmium is toxic and intricate pathways linked to metallothioneins (MT) drive the detoxification process. Whist the mechanisms are well understood in mammalian systems, detailed knowledge is still elusive in invertebrates (which notably differ to mammalian systems). The model nematode Caenorhabditis elegans is ideally suited for assessing metallothionein mediates detoxification in invertebrates as is relatively short-lived, can be easily exposed and its genome is fully sequenced and widely annotated. The aim of the experiment was to identify new MT mediated target genes involved in Cd toxicosis.

Threonine dehydratase couples L-cysteine metabolism to cadmium resistance in Pseudomonas stutzeri 273 through cadmium sulfide nanoparticle biomineralization

Project description:Cysteine is an amino acid containing sulfhydryl (-SH) group which is the basis of cysteine involved in sulfur metabolism and heavy metal detoxification in microorganisms. Here, we demonstrate that adding L-cysteine significantly improves the cadmium resistance and removal ability of Pseudomonas stutzeri 273. Threonine dehydratase (TSD) connects L-cysteine metabolism and cadmium resistance through CdS nanoparticle biomineralization with the ability of catalyzing L-cysteine desulfuration and H2S generation in P. stutzeri 273. Gene knockout of TSD in P. stutzeri 273 results in the decrease of L-cysteine and cadmium resistance, decline of H2S generation, and reduction of CdS biosynthesis ability.

Gene expression analysis of mulberry (Morus atropurpurea) response to cadmium stress

Project description:Mulberry (Morus atropurpurea) is an important economic woody tree with rapid growth rate and large biomass, which had great potential for heavy metals remediation. To further understand the mechanisms involved in cadmium accumulation and detoxification in mulberry, we carried out a transcriptomic study to get insights into the molecular mechanisms of the mulberry response to cadmium stress using RNA-seq analysis with BGISEQ-500.

Whole blood derived cadmium responsive miRNome

Project description:Purpose: Cadmium is a nonessential heavy metal and a well known toxic agent. Cadmium is known to alter the gene expression and signaling but the role of miRNAs during Cadmium exposure is not understood. Methods: Mice were treated with 100 mg/ ml cadmium chloride for 120 days and accumulation of cadmium in blood and organs are confirmed by GFAAS. Subsequently, the total RNA was isolated from the whole blood and small RNA sequencing was executed in Illumina HiSeq 1000. Results: The reads were annotated to the mice genome and miRNAs in miRbase using miRDeep* and novel miRNAs were also predicted. The differential expression was studied by DeSeq Conclusions: This is the first report to reveal the cadmium responsive miRNome. These candidate miRNAs can serve as biomarkers for cadmium

Physiological and transcriptomic analyses reveal sulfur is essential for cadmium detoxification and accumulation in poplar leaves

Project description:Although poplars are good candidates for the phytoremediation of cadmium (Cd)-polluted soils and sulfur is a key player in modulating Cd detoxification and accumulation in plants, the physiological and molecular mechanisms underlying sulfur-mediated Cd accumulation remain largely unknown. To investigate physiological and transcriptomic regulation mechanisms of poplars in response to Cd exposure and different sulphate (S) supply levels, Populus deltoides saplings were exposed to either 0 or 50 µM Cd together with one of low, moderate and high S levels. Cd was accumulated in the leaves of Cd-exposed poplars under moderate S condition, and its accumulation is inhibited by low S but tended to increase by high S. Sulfur nutrition became deficient in Cd-treated leaves, and it was aggravated by low S but improved by high S. Concentrations of cysteine and glutathione were increased in Cd-treated leaves, and the Cd-induced increases were limited by low S but stimulated by high S. In line with the physiological changes, a number of mRNAs and microRNAs (miRNAs) involved in Cd accumulation and sulfur assimilation were identified and the miRNAs-mRNAs networks were dissected. In the networks, miR395 and miR399 members were identified as hub miRNAs and their targets were ATP sulfurylase 3 (ATPS3), and phosphate 2 (PHO2) and beta galactosidase 1 (BGAL1), respectively. These results suggest that Cd-induced changes in Cd accumulation and sulfur assimilation are exacerbated by low S but alleviated by high S supply, and that miRNAs-mRNAs regulatory networks play pivotal roles in sulfur-mediated Cd detoxification and accumulation in poplars.
