Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová, Séverine Marguerite Urfer

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

Role of the cystathionine beta-synthase / H2S pathway in the development of cellular metabolic dysfunction and pseudohypoxia in down syndrome

Theodora Panagaki

Background: Overexpression of the transsulfuration enzyme cystathionine-beta-synthase (CBS), and overproduction of its product, hydrogen sulfide (H2S) are recognized as potential pathogenetic factors in Down syndrome (DS). The purpose of the study was to d ...

Extensive and diverse patterns of cell death sculpt neural networks in insects

Pavan P Ramdya, Chin-Lin Chen

Changes to the structure and function of neural networks are thought to underlie the evolutionary adaptation of animal behaviours. Among the many developmental phenomena that generate change programmed cell death (PCD) appears to play a key role. We show t ...

Perivascular M2 macrophages stimulate tumor relapse after chemotherapy

Michele De Palma, Ioanna Keklikoglou

Tumor relapse after chemotherapy-induced regression is a major clinical problem, because it often involves inoperable metastatic disease. Tumor-associated macrophages (TAM) are known to limit the cytotoxic effects of chemotherapy in preclinical models of c ...

BMP signaling specifies the development of a large and fast CNS synapse

Graham Knott, Ralf Schneggenburger, Enida Gjoni, Elin Kristina Kronander, Le Xiao

excitatory synapses with multiple active zones ensure reliable and fast information transfer at specific points in neuronal circuits. However, the mechanisms that determine synapse size in CNS circuits are largely unknown. Here we use the calyx of Held syn ...

Motor Deficits upon Alpha-Synuclein Expression in the Nigrostriatal System Are Due to a Loss of Dopaminergic Vesicles and Reduced Dopamine Release at an early Stage of Neurodegeneration

Meret Gaugler

Alpha-synuclein is linked to both sporadic and familial forms of Parkinson's disease. The protein represents the major component of Lewy bodies – one of the hallmarks of the disease. Additionally, several point mutations and locus multiplications in the ge ...

Sulfide-binding hemoglobins: effects of mutations on active-site flexibility

Majed Chergui

The dynamics of Hb I (HbI) from the clam Lucina pectinata, from wild-type sperm whale (SW) myoglobin, and from the L29F/H64Q/V68F triple mutant of SW, both unligated and bound to hydrogen sulfide (H2S), have been studied in mol. dynamics simulations. Featu ...

Activation of the peroxisome proliferator-activated receptor alpha protects against myocardial ischaemic injury and improves endothelial vasodilatation

Johan Auwerx, Kristina Schoonjans

BACKGROUND: The peroxisome proliferator-activated receptor alpha (PPARalpha) plays an important role in the metabolism of lipoproteins and fatty acids, and seems to protect against the development of atherosclerosis. To evaluate the possible protective rol ...
