Temporal tracking of cysteine 34 oxidation of plasma albumin as a biomarker of muscle damage following a bout of eccentric exercise
ConclusionThe levels of thiol-oxidised albumin increase in response to EIMD and remain elevated for several days post-exercise. The temporal pattern of change in the level of thiol-oxidised albumin suggests that this may be a useful biomarker of muscle repair post-EIMD. (Source: European Journal of Applied Physiology)

Network-neuron interactions underlying sensory responses of layer 5 pyramidal tract neurons in barrel cortex
by Arco Bast, Rieke Fruengel, Christiaan P. J. de Kock, Marcel Oberlaender Neurons in the cerebral cortex receive thousands of synaptic inputs per second from thousands of presynaptic neurons. How the dendritic location of inputs, their timing, strength, and presynaptic origin, in conjunction with complex dendritic physiology, impact the transformation of synaptic input into action potential (AP) output remains generally unknown forin vivo conditions. Here, we introduce a computational approach to reveal which properties of the input causally underlie AP output, and how this neuronal input-output computation is influenced...

Gulf toadfish (Opsanus beta) gill neuroepithelial cells in response to hypoxia exposure
AbstractNeuroepithelial cells (NECs) within the fish gill contain the monoamine neurochemical serotonin (5-HT), sense changes in the partial pressure of oxygen (PO2) in the surrounding water and blood, and initiate the cardiovascular and ventilatory responses to hypoxia. The distribution of neuroepithelial cells (NECs) within the gill is known for some fish species but not for the Gulf toadfish,Opsanus beta, a fish that has always been considered hypoxia tolerant. Furthermore, whether NEC size, number, or distribution changes after chronic exposure to hypoxia, has never been tested. We hypothesize that toadfish NECs will r...

Macrophages in necrotic liver lesion repair: opportunities for therapeutical applications
Am J Physiol Cell Physiol. 2024 Apr 15. doi: 10.1152/ajpcell.00053.2024. Online ahead of print.ABSTRACTHealthy livers contain 80% of body resident macrophages known as Kupffer cells. In diseased livers, the number of Kupffer cells usually drops, but is compensated by infiltration of monocyte-derived macrophages, which can differentiate into Kupffer-like cells. Early studies suggest that Kupffer cells play important roles in both promoting liver injury as well as liver regeneration. Yet, the distinction of the functionalities from resident and infiltrating macrophages is not always made. By using more specific macrophage ma...

Extracellular vesicles and their therapeutic applications: a review article (part1)
Int J Physiol Pathophysiol Pharmacol. 2024 Feb 25;16(1):1-9. eCollection 2024.ABSTRACTExtracellular vesicles (EVs) have emerged as a captivating field of study in molecular biology with diverse applications in therapeutics. These small membrane-bound structures, released by cells into the extracellular space, play a vital role in intercellular communication and hold immense potential for advancing medical treatments. EVs, including exosomes, microvesicles, and apoptotic bodies, are classified based on size and biogenesis pathways, with exosomes being the most extensively studied. The aim of this study was to examine the mo...

Establishment and characterization of a kidney cell line from hybrid snakehead (male Channa argus × female Channa maculata) and its susceptibility to hybrid snakehead rhabdovirus (HSHRV)
In this study, a fish cell line called CAMK, derived from the kidneys of hybrid snakehead, was established and characterized. CAMK cells exhibited the maximum growth rate at 28 °C in Leibovitz's-15 medium supplemented with 10% fetal bovine serum(FBS). Karyotyping revealed diploid chromosomes in 54% of the cells at the 50th passage (2n = 66), and 16S rRNA sequencing validated that CAMK cells originated fromhybrid snakehead, and the detection of kidney-specific antibodies suggested that it originated from kidney. .The culture was free from mycoplasma contamination, and the green fluorescent protein gene was effectively tran...

Zinc-chelating BET bromodomain inhibitors equally target islet endocrine cell types
We report the synthesis of a novel, Zn2+-chelating derivative of the pan-BETi (+)-JQ1, (+)-JQ1-DPA, in which (+)-JQ1 was conjugated to dipicolyl amine (DPA). As controls, we synthesized (+)-JQ1-DBA, a non-Zn2+-chelating derivative, and (-)-JQ1-DPA, an inactive enantiomer that chelates Zn2+. Molecular modeling and biophysical assays showed that (+)-JQ1-DPA and (+)-JQ1-DBA retain potent binding to BET bromodomains in vitro. Cellular assays demonstrated (+)-JQ1-DPA attenuated NF-ĸB target gene expression in β-cells stimulated with the pro-inflammatory cytokine interleukin 1β. To assess β-cell selectivity, we isolated isle...
