Translocation of penetratin-like peptides involving calcium-dependent interactions between glycosaminoglycans and phosphocholine headgroups of the membrane lipid bilayer [PDF]

RSC Chemical Biology
Cell-penetrating peptides (CPPs) can internalize ubiquitously in cells. To explore the specific targeting issue of CPPs, we used glycosaminoglycan (GAG)-binding peptides previously identified in Otx2 and En2 homeoproteins (HPs).

Quantitative phase microscopy for non-invasive live cell population monitoring

Scientific Reports, 2021
We present here a label-free development based on preexisting Quantitative Phase Imaging (QPI) that allows non-invasive live monitoring of both individual cells and cell populations.

Deletion of Proton Gradient Regulation 5 (PGR5) and PGR5-Like 1 (PGRL1) proteins promote sustainable light-driven hydrogen production in Chlamydomonas reinhardtii due to increased PSII activity under sulfur deprivation

Frontiers in Plant Science, 2015
Continuous hydrogen photo-production under sulfur deprivation was studied in the Chlamydomonas reinhardtii pgr5 pgrl1 double mutant and respective single mutants.

Relationships between serotonin availability and frontolimbic response to fearful and threatening faces

Scientific Reports, 2023
Serotonin is a critical neurotransmitter in the regulation of emotional behavior. Although emotion processing is known to engage a corticolimbic circuit, including the amygdala and prefrontal cortex, exactly how this brain system is modulated by ...

VEGF-A/Notch-Induced Podosomes Proteolyse Basement Membrane Collagen-IV during Retinal Sprouting Angiogenesis

Cell Reports, 2016
During angiogenic sprouting, endothelial tip cells emerge from existing vessels in a process that requires vascular basement membrane degradation. Here, we show that F-actin/cortactin/P-Src-based matrix-degrading microdomains called podosomes contribute ...

Endurance Exercise Ability in the Horse: A Trait with Complex Polygenic Determinism

Frontiers in Genetics, 2017
Endurance horses are able to run at more than 20 km/h for 160 km (in bouts of 30–40 km). This level of performance is based on intense aerobic metabolism, effective body heat dissipation and the ability to endure painful exercise.

Proteomic Study of SUMOylation During Solanum tuberosum–Phytophthora infestans Interactions

Molecular Plant-Microbe Interactions, 2017
Invasive plant pathogens have developed the ability to modify the metabolism of their host, promoting metabolic processes that facilitate the growth of the pathogen at the general expense of the host.

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation

Advanced Science, EarlyView.
Using a newly developed Droplet Interface Bilayer‐Pipette assay, the authors show that two segments of the CyaA toxin cross membranes by distinct mechanisms. One segment translocates spontaneously, whereas the translocation of the other depends on membrane potential.

The genome and diet of a 35,000‐year‐old Canis lupus specimen from the Paleolithic painted cave, Chauvet‐Pont d'Arc, France

Ecology and Evolution, 2022
The Chauvet‐Pont‐d'Arc Cave (Ardèche, France) contains some of the oldest Paleolithic paintings recorded to date, as well as thousands of bones of the extinct cave bear, and some remains and footprints of other animals.
