Abstract Halophyte species implement a “salt-including” strategy, sequestering significant amounts of Na+ to cell vacuoles. This requires reduction passive leak from the vacuole. In this work, we used quinoa (Chenopodium quinoa) investigate ability halophytes regulate Na+-permeable slow-activating (SV) and fast-activating (FV) tonoplast channels, linking it with accumulation in mesophyll cells salt bladders as well leaf photosynthetic efficiency under stress. Our data indicate that young...
Halophytes species can be used as a highly convenient model system to reveal key ionic and molecular mechanisms that confer salinity tolerance in plants. Earlier, we reported quinoa (Chenopodium Willd.), facultative C3 halophyte species, efficiently control the activity of slow (SV) fast (FV) tonoplast channels match specific growth conditions by ensuring most accumulated Na+ is safely locked vacuole (Bonales-Alatorre et al. (2013) Plant Physiology). This work extends these finding comparing...
Efforts to breed salt tolerant crops could benefit from investigating previously unexplored traits. One of them is a tissue succulency. In this work, we have undertaken an electrophysiological and biochemical comparison properties mesophyll storage parenchyma leaf tissues succulent halophyte species Carpobrotus rosii ("pigface"). We show that cells C. rossii act as Na+ sink possessed both higher sequestration (298 vs. 215 mM NaCl in mesophyll) better K+ retention ability. The latter traits...
Microelectrode ion flux estimation (MIFE) and patch-clamp techniques were combined for noninvasive K(+) measurements recording of activities the dominant channels in early phases apoptosis Jurkat cells. Staurosporine (STS, 1 microM) evoked rapid (peaking around 15 min) transient efflux, which then gradually decreased. This efflux occurred concurrently with increase background (K(bg)) TWIK-related spinal cord channel-like current density, followed by a drastic decrease concomitant membrane...
Activity of tonoplast slow vacuolar (SV, or TPC1) channels has to be under a tight control, avoid undesirable leak cations stored in the vacuole. This is particularly important for salt-grown plants, ensure efficient Na(+) sequestration. In this study we show that choline, cationic precursor glycine betaine, efficiently blocks SV leaf and root vacuoles two chenopods, Chenopodium quinoa (halophyte) Beta vulgaris (glycophyte). At same time, betaine proline, major cytosolic organic osmolytes,...
Different studies in experimental diabetes models suggest that zinc oxide nanoparticles (ZnONPs) are useful as antidiabetic agents. However, this evidence was performed and measured long-term treatments with repeated doses of ZnONPs. This work aimed to evaluate the ZnONPs acute effects on glycemia during next six h after an oral or intraperitoneal administration treatment healthy diabetic rats. In study, streptozotocin-nicotinamide male Wistar rats were used a model. 10 mg/kg did not modify...
The aim of this work was to determine whether Capsaicin may exert a vascular regulation through the activation CB1 and/or CB2 receptors causing vasorelaxation in rat aorta. Our results show location TRPV1 mainly endothelial and smooth muscle cells membrane. Nevertheless, caused artery mechanism independent TRPV1, since specific antagonists Capsazepine SB-366791 did not block effect Capsaicin. Because significant expression has been previously reported aorta, we used for these two prior...
Various types of non-neuronal cells, including tumors, are able to produce acetylcholine (ACh), which acts as an autocrine/paracrine growth factor. T lymphocytes represent a key component the cholinergic system. cells-derived ACh is involved in stimulation their activation and proliferation, regulator immune response. The aim present work was summarize data about components machinery lymphocytes, with emphasis on comparison healthy leukemic cells. Cell lines derived from acute lymphoblastic...
The cafeteria diet (CAF) is a superior model in animal experiments compared to the conventional high-fat (HFD), effectively inducing obesity, metabolic disturbances and multi-organ damage. Nevertheless, its impact on gut microbiota composition during progression of along with repercussions enteric nervous system (ENS) gastrointestinal motility has not been completely elucidated. To gain more insight into effects CAF gut, C57BL/6 mice were fed or standard for 2 8 weeks. CAF-fed experienced...
Extracellular synthesis of functional cyclodextrins (CDs) as intermediates starch assimilation is a convenient microbial adaptation to sequester substrates, increase the half-life carbon source, carry bioactive compounds, and alleviate chemical toxicity through formation CD-guest complexes. Bacteria encoding four steps carbohydrate metabolism pathway via (CM-CD) actively internalize CDs across membrane putative type I ATP-dependent ABC sugar importer system, MdxEFG-(X/MsmX). While first step...
