Functional dissection of the multi-domain di-heme cytochrome c(550) from Thermus thermophilus. [PDF]

open access: yesPLoS ONE, 2013
In bacteria, oxidation of sulfite to sulfate, the most common strategy for sulfite detoxification, is mainly accomplished by the molybdenum-containing sulfite:acceptor oxidoreductases (SORs).

Import of cytochrome c into mitochondria [PDF]

open access: yes, 1989
The covalent attachment of heme to apocytochrome c, and therefore the import of cytochrome c into mitochondria, is dependent on both NADH plus a cytosolic cofactor that has been identified to be FMN or FAD.

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Phosphorylation disrupts long-distance electron transport in cytochrome c

open access: yesNature Communications, 2022
Electron transfer between mitochondrial cytochrome c and subunit of cytochrome bc 1 can proceed at long distance. Here the authors investigate further the mechanism and show phosphorylation regulation of the interactions between the protein partners in ...

Phylogenetic and functional analysis of cyanobacterial Cytochrome c6-like proteins

open access: yesFrontiers in Plant Science, 2023
All known photosynthetic cyanobacteria carry a cytochrome c6 protein that acts transferring electrons from cytochrome b6f complex to photosystem I, in photosynthesis, or cytochrome c oxidase, in respiration.

Rate-limiting Step Preceding Cytochrome c Release in Cells Primed for Fas-mediated Apoptosis Revealed by Analysis of Cellular Mosaicism of Respiratory Changes [PDF]

open access: yes, 2001
In the present work, Jurkat cells undergoing anti-Fas antibody (anti-Fas)-triggered apoptosis exhibited in increasing proportion a massive release of cytochrome c from mitochondria, as revealed by double-labeling confocal immunofluorescence microscopy ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

open access: yesMolecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Redox-controlled proton gating in bovine cytochrome c oxidase. [PDF]

open access: yesPLoS ONE, 2013
Cytochrome c oxidase is the terminal enzyme in the electron transfer chain of essentially all organisms that utilize oxygen to generate energy. It reduces oxygen to water and harnesses the energy to pump protons across the mitochondrial membrane in ...

The role of a disulfide bridge in the stability and folding kinetics of Arabidopsis thaliana cytochrome c6A [PDF]

open access: yes, 2011
Cytochrome c 6A is a eukaryotic member of the Class I cytochrome c family possessing a high structural homology with photosynthetic cytochrome c 6 from cyanobacteria, but structurally and functionally distinct through the presence of a disulfide bond and

Identifying prognostic targets in metastatic prostate cancer beyond AR

open access: yesFEBS Open Bio, EarlyView.
Genome‐wide functional screens combined with a large gene expression database and clinical outcomes can identify new therapeutic vulnerabilities in prostate cancer. Eight potentially druggable targets demonstrated strong dependency in cell lines, were associated with worse prognosis clinically, and showed evidence of protein expression in prostate ...
