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.

Induced Photoelectron Circular Dichroism as a Probe for Distinguishing Diastereotopic Lone Electron Pairs

Angewandte Chemie International Edition, EarlyView.
Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Genetic and Transcriptomic Profiles Identify Potential Therapeutic Targets of Concurrent Follicular and Diffuse Large B-Cell Lymphoma and Transformed Follicular Lymphoma. [PDF]

Hematol Oncol
ABSTRACT Concurrent follicular and diffuse large B‐cell lymphoma (FL/DLBCL) and transformed follicular lymphoma (tFL) are distinct B‐cell lymphoma entities, posing challenges for understanding pathogenesis and clinical management. The clinical characteristics of 98 FL/DLBCL, 31 tFL, 403 FL1‐2/3A, and 608 DLBCL patients were analyzed. DNA sequencing was
