Complex oscillatory redox dynamics with signaling potential at the edge between normal and pathological mitochondrial function
(Frontiers, 2014-06)
The time-keeping properties bestowed by oscillatory behavior on functional rhythms represent an evolutionarily conserved trait in living systems. Mitochondrial networks function as timekeepers maximizing energetic output ...
Driving the catalytic activity of a transmembrane thermosensor kinase
(Birkhauser Verlag Ag, 2020-10)
DesK is a Bacillus thermosensor kinase that is inactive at high temperatures but turns activated when the temperature drops below 25 °C. Surprisingly, the catalytic domain (DesKC) lacking the transmembrane region is more ...
Long-lasting primed state in maize plants: Salicylic acid and steroid signaling pathways as key players in the early activation of immune responses in silks
(American Phytopathological Society, 2018-12)
In the present study, we investigated the induced systemic resistance (ISR) activated by the beneficial fungus Trichoderma atroviride in maize plants, and the early immunological responses triggered after challenge with ...
Design of a portable device for continuous 24h measurement of biological signals in large animals
(Sociedad Argentina de Bioingeniería, 2019-03)
The clinical interest in the measurement of pulse wave velocity (PWV), as an indirect index of arterial stiffness, has led to the development of new devices whose characteristics and limitations are currently being analyzed ...
Insect-corn kernel interaction: Chemical signaling of the grain and host recognition by Sitophilus zeamais
(Pergamon-Elsevier Science Ltd, 2018-12)
In living organisms, the cuticle has structural functions and is involved through chemical signaling in biological interactions such as plant-insect and provides protection against biotic and abiotic factors, thereby ...
The LNK gene family: At the crossroad between light signaling and the circadian clock
(Molecular Diversity Preservation International, 2019-01)
Light signaling pathways interact with the circadian clock to help organisms synchronize physiological and developmental processes to periodic environmental cycles. The plant photoreceptors responsible for clock resetting ...
Neuronal loss and abnormal BMP/Smad signaling in the myenteric plexus of diabetic rats
(Elsevier Science, 2011-10)
Bone morphogenetic proteins (BMPs) are critical molecules during gut morphogenesis. However, little is known about their participation in the homeostasis of adult gut and their possible role in diseases. Gastrointestinal ...
Store depletion induces Gαq-mediated PLCβ1 activity to stimulate TRPC1 channels in vascular smooth muscle cells
(Federation of American Societies for Experimental Biology, 2016-02)
Depletion of sarcoplasmic reticulum (SR) Ca2+ stores activates store-operated channels (SOCs) composed of canonical transient receptor potential (TRPC) 1 proteins in vascular smooth muscle cells (VSMCs), which contribute ...
Signal convergence in fruits: a result of selection by frugivores?
(Wiley Blackwell Publishing, Inc, 2010-01)
The Dispersal Syndrome hypothesis remains contentious, stating that apparently nonrandom associations of fruit characteristics result from selection by seed dispersers. We examine a key assumption under this hypothesis, ...
Cry1 and GPA1 signaling genetically interact in hook opening and anthocyanin synthesis in Arabidopsis
(Springer, 2012-10)
While studying blue light-independent effects of cryptochrome 1 (cry1) photoreceptor, we observed premature opening of the hook in cry1 mutants grown in complete darkness, a phenotype that resembles the one described for ...
