TranscriptomicsRNA-seq of Arabidopsis spl7 identifies two genes required for copper acquisition and a copper dependence of iron homeostasis
The transition metal copper (Cu) is an essential element for all living organisms. In plants, Cu plays key roles in electron transport chains of chloroplasts and mitochondria, as well as in cell wall metabolism, ethylene perception, molybdenum cofactor synthesis and oxidative stress protection. Beca...

MetabolomicsStable isotope labelling of Toxoplasma gondii under iron and copper restriction

Toxoplasma uses metal nutrients like iron and copper for vital functions in their energy metabolism. Here, we have used stable isotope labelling to track the incorporation of glucose and glutamine into metabolic pathways, primarily focusing on central carbon metabolism, when these metals are disr...

TranscriptomicsThe Arabidopsis copper transport protein COPT2 and the responses under copper and iron deficiency.
Copper and iron are essential micronutrients for most living organisms because they participate as cofactors in biological processes including respiration, photosynthesis and oxidative stress protection. In many eukaryotic organisms, including yeast and mammals, copper and iron homeostases are highl...

TranscriptomicsTRANSCRIPTIONAL REMODELLING IN RESPONSE TO CHANGING COPPER LEVELS IN WILSON DISEASE MODEL OF SACCHAROMYCES CEREVISIAE
A 3 x 2 factorial design was used to elucidate the genome-wide transcriptional response to the deletion of yeast ortholog of Wilson and Menkes disease causing gene; CCC2, at changing copper levels. Homozygous deletion mutant of CCC2, which encodes Cu+2 transporting P-type ATPase required to export c...

no omics definedTranscription profiling of copper-stressed Pseudomonas aeruginosa
Anthropogenic pollution has increased the levels of heavy metals in the environment. Bacterial populations continue to thrive in highly polluted environments and bacteria must have mechanisms to counter heavy metal stress. We chose to examine the response of the environmentally-relevant organism P...

TranscriptomicsA new structural paradigm in copper resistance in a human pathogen
Copper is essential for both innate and adaptive immune function and copper resistance has emerged as an important determinant of virulence of microbial pathogens. In the human pathogen Streptococcus pneumoniae (Spn), cytoplasmic copper resistance is mediated by an operon encoding the copper-respons...

TranscriptomicsSystems analysis of Chlamydomonas Cu nutrition reveals connections between Cu and multiple O2-dependent metabolic steps
We used digital gene expression (NlaIII sequence tags) and RNA-Seq to compare the transcriptomes of Cu-replete vs. Cu–deficient Chlamydomonas wild-type cells to reveal dozens of mRNAs whose abundance is modified. Half of the corresponding genes are targets of CRR1, a master regulator of nutritional ...

TranscriptomicsCopper-induced deregulation of microRNA expression in the zebrafish olfactory system
Although environmental trace metals, such as copper (Cu), can disrupt normal olfactory function in fish, the underlying molecular mechanisms of metal-induced olfactory injury have not been elucidated. Current research has suggested the involvement of epigenetic modifications. To address this hypothe...
