Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene

Advanced Science, EarlyView.
Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.

Positive Autoregulation of an Acyl-Homoserine Lactone Quorum-Sensing Circuit Synchronizes the Population Response

mBio, 2017
Many proteobacteria utilize acyl-homoserine lactone quorum-sensing signals. At low population densities, cells produce a basal level of signal, and when sufficient signal has accumulated in the surrounding environment, it binds to its receptor, and ...

Green bean (Vigna radiata) seedling growth inhibition by Chromobacterium violaceum under in-vitro condition. [PDF]

, 2010
Chromobacterium violaceum is a pathogenic soil bacterium producing violacein and hydrogen cyanide both of which is controlled by quorum sensing with the same signal molecule homoserine lactone (C6-HSL).

Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

Advanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

Quorum sensing intervened bacterial signaling: Pursuit of its cognizance and repression

Journal of Genetic Engineering and Biotechnology, 2018
Bacteria communicate within a system by means of a density dependent mechanism known as quorum sensing which regulate the metabolic and behavioral activities of a bacterial community.

Mean-field equation for a stochastic many-particle model of quorum-sensing microbial populations

, 2018
We prove a mean-field equation for the dynamics of quorum-sensing microbial populations. In the stochastic many-particle process, individuals of a population produce public good molecules to different degrees.

Circulating Tumor Cells Shed Shearosome Extracellular Vesicles in Capillary Bifurcations That Activate Endothelial and Immune Cells

Advanced Science, EarlyView.
Using microfluidic models of capillary networks, this study discovered that fluid shear stresses on circulating tumor cells transiting through capillary‐sized bifurcations shed a novel class of shear‐dependent large extracellular vesicle, “shearosomes”, whose proteome comprises of over 3000 distinct proteins.
