Distribution of superoxide and hydrogen peroxide in Arabidopsis root and their influence on root development: possible interaction with peroxidases.

open access: yesNew Phytologist, 2007
The respective distribution of superoxide (O(2) (.-)) and hydrogen peroxide (H(2)O(2)), two reactive oxygen species (ROS) involved in root growth and differentiation, was determined within the Arabidopsis root tip.

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

open access: yesFEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Destroy and Exploit: Catalyzed Removal of Hydroperoxides from the Endoplasmic Reticulum

open access: yesInternational Journal of Cell Biology, 2013
Peroxidases are enzymes that reduce hydroperoxide substrates. In many cases, hydroperoxide reduction is coupled to the formation of a disulfide bond, which is transferred onto specific acceptor molecules, the so-called reducing substrates.

Fe-MoS$_2$ nanoenzyme with photothermal enhanced enzyme activity for glucose colorimetric detection [PDF]

open access: yesarXiv
With the development of nanotechnology, it has been discovered that some nanomaterials have the activity of mimicking enzymes. This type of inorganic nanomaterial with characteristics similar to natural enzymes is called nanoenzyme. Compared with natural enzymes, nanoenzymes have advantages such as low deactivation, good stability, low production and ...

Efficacy of Put and Spd sprayed on leaves from Brassica juncea plants against Cd2+-induced oxidative stress [PDF]

open access: yesarXiv, 2008
The protective effect exerted by polyamines (Put and Spd) against cadmium (Cd) stress was investigated in Brassica juncea plants. Treatment with CdCl2 (75 micro-Mole) resulted in a rise of Cd accumulation, a decrease of fresh and dry weights in every plant organ, an increase of free polyamine content at limb and stem levels as well as a decrease at ...

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 ...

Pt nanoparticles dispersed in a metal-organic framework as peroxidase mimics for colorimetric detection of GSH [PDF]

open access: yesarXiv
Metal-organic skeleton materials have been widely used in catalysis with their porous structure and adsorption properties. Precious metal nanoparticles have good catalytic properties. If the noble metal nanoparticles are adsorbed on the MOFs surface, the active sites can be increased and the catalytic effect of the materials can be greatly improved. We
