Regulation of Ncbe in the Choroid Plexus of Mice after Hemorrhage-Induced Hydrocephalus
FASEB J. 2022 May;36 Suppl 1. doi: 10.1096/fasebj.2022.36.S1.R3405.ABSTRACTThe choroid plexus (CP) is a small tissue located inside brain ventricles. It is responsible for the production of most of the cerebrospinal fluid (CSF); approximately 500 mL of CSF per day in the adult human [1, 2]. CSF production occurs as a net result of transcellular movement of salt and water, carried out by various cellular transporters. Ncbe is a sodium-coupled bicarbonate transporter located in the basolateral membrane of the choroid plexus epithelial (CPE) cells. It transports Na+ and HCO3 - into the cell in exchange for Cl- . Ncbe is the m...

Claudin-5 Affects Endothelial Autophagy in Response to Early Hypoxia
Hypoxic injury to cerebrovascular endothelial cells (ECs) after stroke leads to blood-brain barrier (BBB) dysfunction, which is commonly associated with disruptions of endothelial tight junctions (TJs) and increased permeability. Therefore, maintaining the structural integrity and proper function of the BBB is essential for the homeostasis and physiological function of the central nervous system (CNS). Our previous study revealed that autophagy functions on protecting the BBB by regulating the dynamics of Claudin-5, the essential TJ protein, under short-term starvation or hypoxia conditions. Here, we show that in zebrafish...

Intratubular, Intracellular, and Mitochondrial Angiotensin II/AT1 (AT1a) Receptor/NHE3 Signaling Plays a Critical Role in Angiotensin II-Induced Hypertension and Kidney Injury
The objectives of this invited article are to review and discuss our recent findings that (a) circulating and intratubular Ang II is taken up by the proximal tubules via the (AT1) AT1a receptor-dependent mechanism, (b) intracellular administration of Ang II in proximal tubule cells or adenovirus-mediated overexpression of an intracellular Ang II fusion protein selectively in the mitochonria of the proximal tubules induces blood pressure responses, and (c) genetic deletion of AT1 (AT1a) receptors or the Na+/H+ exchanger 3 selectively in the proximal tubules decreases basal blood pressure and attenuates Ang II-induced hypert...

SOD1 Overexpression Prevents Acute Hyperglycemia-Induced Cerebral Myogenic Dysfunction: Relevance to Contralateral Hemisphere and Stroke Outcomes.
Conclusion: Our results showed that SOD1 overexpression nullified the detrimental effects of HG on myogenic tone and stroke outcomes, and that contralateral hemisphere may be a novel target for the management of acute hyperglycemic stroke. PMID: 25552308 [PubMed - as supplied by publisher]
