Unraveling the Heterogeneity of Cargo Distribution in the Exogenous Association of Proteins With Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.

Signal Recognition Particle RNA Contributes to Oxidative Stress Response in Deinococcus radiodurans by Modulating Catalase Localization

open access: yesFrontiers in Microbiology, 2020
The proper functioning of many proteins requires their transport to the correct cellular compartment or their secretion. Signal recognition particle (SRP) is a major protein transport pathway responsible for the co-translational movement of integral ...

Cold Atmospheric Plasma Selectively Disrupts Breast Cancer Growth in a Bioprinted 3D Tumor‐Stroma Co‐Culture Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This research introduces a cold plasma‐based platform for treating breast cancer bone metastases. Using a novel bioprinted 3D tumor‐stroma model, it highlights the selective antitumor effects of plasma‐generated reactive species. The platform aims to advance non‐invasive therapeutic strategies, offering potential clinical applications in controlling ...

Genomic and proteomic evidences unravel the UV-resistome of the poly-extremophile Acinetobacter sp. Ver3 [PDF]

open access: yes, 2015
Ultraviolet radiation can damage biomolecules, with detrimental or even lethal effects for life. Even though lower wavelengths are filtered by the ozone layer, a significant amount of harmful UV-B and UV-A radiation reach Earth?s surface, particularly in

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.
