Impact of Matrix Gel Variations on Primary Culture of Microvascular Endothelial Cell Function.

Objective: The endothelium regulates crucial aspects of vascular function, including hemostasis, vasomotor tone, proliferation, immune cell adhesion, and microvascular permeability. Endothelial cells (ECs), especially in arterioles, are pivotal for flow distribution and peripheral resistance regulation. Investigating vascular endothelium physiology, particularly in microvascular ECs, demands precise isolation and culturing techniques.

Short-term high-fat diet feeding of mice suppresses catecholamine-stimulated Ca signalling in hepatocytes and intact liver.

Excess consumption of carbohydrates, fat and calories leads to non-alcoholic fatty liver disease (NAFLD) and hepatic insulin resistance; these are major factors in the pathogenesis of type II diabetes. Hormones and catecholamines acting through G-protein coupled receptors (GPCRs) linked to phospholipase C (PLC) and increases in cytosolic Ca ([Ca ] ) regulate many metabolic functions of the liver. In the intact liver, catabolic hormones such as glucagon, catecholamines and vasopressin integrate and synergize to regulate the frequency and extent to which [Ca ] waves propagate across hepatic lobules to control metabolism.

Rare CACNA1H and RELN variants interact through mTORC1 pathway in oligogenic autism spectrum disorder.

Oligogenic inheritance of autism spectrum disorder (ASD) has been supported by several studies. However, little is known about how the risk variants interact and converge on causative neurobiological pathways. We identified in an ASD proband deleterious compound heterozygous missense variants in the Reelin (RELN) gene, and a de novo splicing variant in the Cav3.

Fmr1 exon 14 skipping in late embryonic development of the rat forebrain.

Background: Fragile X syndrome, the major cause of inherited intellectual disability among men, is due to deficiency of the synaptic functional regulator FMR1 protein (FMRP), encoded by the FMRP translational regulator 1 (FMR1) gene. FMR1 alternative splicing produces distinct transcripts that may consequently impact FMRP functional roles. In transcripts without exon 14 the translational reading frame is shifted.
