“Lipotoxicity occurs as a consequence of chronic exposure of non-adipose tissue and cells to elevated concentrations of fatty acids, triglycerides and/or cholesterol. The contribution of mitochondria to lipotoxic cell dysfunction, damage and death is associated with elevated production of reactive oxygen species and initiation of apoptosis. Although there is a broad consensus on the involvement of these phenomena with lipotoxicity, the molecular mechanisms that initiate, mediate and trigger mitochondrial dysfunction in response to substrate overload remain unclear. Here, we focus on protein phosphorylation as an important phenomenon in lipotoxicity that harms mitochondria-related signal transduction and integration in cellular metabolism. Moreover, the degradation of mitochondria by mitophagy is discussed as an important landmark that leads to cellular apoptosis Selinexor datasheet in lipotoxicity.”
“The rat vas deferens has scattered sensory afferens plus a dense network of sympathetic motor efferens; these fibers are not known to interact functionally. We ascertained whether sensory fibers modulate the release of sympathetic transmitters through the release of calcitonin generelated peptide (CGRP) and reciprocally

assessed whether sympathetic transmitters modulate the overflow of ir-CGRP from sensory fibers. The tissue overflow of electrically evoked sympathetic co-transmitters (ATP/metabolites, BMS-777607 noradrenaline (NA), and immunoreactive neuropeptide tyrosine (ir-NPY)) PF299804 mouse and the motor responses elicited were quantified following either exogenous CGRP or capsaicin

application to elicit peptide release. Conversely, the outflow of ir-CGRP was examined in the presence of sympathetic transmitters. Exogenous CGRP reduced in a concentration-dependent manner the electrically evoked outflow of ATP/metabolites, NA, and ir-NPY with EC50 values of 1.3, 0.18, and 1.9 nM, respectively. CGRP also reduced the basal NA overflow. The CGRP-evoked modulation was blocked by CGRP8-37 or H-89. Release of endogenous CGRP by capsaicin significantly reduced the basal overflow of NA, ir-NPY, and the electrically evoked sympathetic transmitter release. ADP, 2-methylthioadenosine-5′-O-diphosphate (2-MeSADP), or UTP decreased the electrically evoked ir-CGRP overflow, whereas clonidine, a,beta-methyleneadenosine 5′-triphosphate (alpha,beta-mATP), or adenosine (ADO) were inactive. CGRP acting postjunctionally also reduced the motor responses elicited by exogenous NA, ATP, or electrically evoked contractions. We conclude that CGRP exerts a presynaptic modulator role on sympathetic nerve endings and reciprocally ATP or related nucleotides influence the release of ir-CGRP from sensory fibers, highlighting a dynamic sympatho-sensory control between sensory fibers and sympathetic nerve ending.
