Liu S, Li W. Prazosin blocks apoptosis of endothelial progenitor cells through downregulating the Akt/NF-κB signaling pathway in a rat cerebral infarction model. Exp Ther Med 2020; 20:2577-2584. [PMID: 32765751 PMCID: PMC7401792 DOI: 10.3892/etm.2020.9009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Accepted: 05/13/2020] [Indexed: 11/13/2022] Open
Abstract
Endothelial progenitor cells (EPCs) can enhance the recanalization of thrombosis during the progression of cerebral infarction. Prazosin plays a therapeutic role in expanding the peripheral vasculature and regulating infarction cardiosclerosis by inhibiting phosphoinositide signaling. However, the possible mechanisms underlying the therapeutic effects of prazosin have not been fully explored. The purpose of the present study was to analyze the anti-apoptotic effects of prazosin on EPCs in a rat cerebral infarction model. The results showed that prazosin treatment decreased apoptosis of EPCs. Prazosin treatment decreased the serum expression levels of the inflammatory factors, interleukin-1β and tumor necrosis factor-α in rats with cerebral infarctions as well as in EPCs in vitro. In addition, prazosin reduced the expression levels of Akt, NF-κB, phosphorylated (p)-Akt and p-NF-κB in EPCs and the middle cerebral artery of rats with cerebral infarction. These findings demonstrated that prazosin inhibited EPC apoptosis in the cerebral infarction rats through targeting the Akt/NF-κB signaling pathway. In conclusion, these results indicated that prazosin has a preventive effect on cerebral infarction by inhibiting EPC apoptosis and by inhibiting the inflammatory response in vitro and in vivo through regulating the Akt/NF-κB signaling pathway.

Blood-brain barrier dysfunction: the undervalued frontier of hypertension. J Hum Hypertens 2020; 34:682-691.

Abstract
The blood-brain barrier (BBB) constitutes the complex anatomic and physiologic interface between the intravascular compartment and the central nervous system, and its integrity is paramount for the maintenance of the very sensitive homeostasis of the central nervous system. Arterial hypertension is a leading cause of morbidity and mortality. The BBB has been shown to be disrupted in essential hypertension. BBB integrity is important for central autonomic control and this may be implicated in the pathophysiology of hypertension. On the other hand, evidence from experimental studies indicates that BBB disruption can be present in both hypertensive disease and dementia syndromes, suggesting a possibly key position of loss of BBB integrity in the pathophysiological pathways linking arterial hypertension with cognitive decline. Although much still remains to be elucidated with respect to the exact underlying mechanisms, the discovery of novel pathological pathways has changed our understanding of adult dementia and central nervous system disease overall, pointing out-in parallel-new potential therapeutic targets. The aim of this review is to summarize current scientific knowledge relevant to the pathophysiologic pathways that are involved in the disruption of the BBB function and potentially mediate hypertension-induced cognitive impairment. In parallel, we underline the differential cognition-preserving effect of several antihypertensive agents of similar blood pressure-lowering capacity, highlighting the presence of previously under-recognized BBB-protective actions of these drugs.

Abstract
Arterial hypertension is associated with elevated risk of cognition decline and vascular dementia development, as the Alzheimer disease development. Therefore, antihypertension therapy might be of preventive value. The review is focused on literary data that witness on, despite controversial, evidence of cerebroprotective action of the range of antihypertension medications. Especially, dihydropyridine calcium antagonists, diuretics and some blockers of renin-angiotensin-aldosterone system. These act not only via blood pressure decrease, but due to additional specific neuroprotective mechanisms. This makes it to consider calcium antagonists and diuretics as a major component of systemic hypertension management, incl. elderly and senile patients, aiming to prevent cognition decline and dementia of various types development.Nitrendipine, among the calcium channels antagonists, and indapamide among diuretics have acquired the broadest evidence that points on their cerebroprotective properties.

Abstract
INTRODUCTION The benzothiadiazines and high ceiling diuretics (hydrochlorothiazide, hydroflumethiazide, quinethazone, metolazone, chlorthalidone, indapamide, furosemide and bumetanide) contain primary sulfamoyl moieties acting as zinc-binding groups in the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1). These drugs are widely used clinically and were recently shown to weakly inhibit isoforms CA I and II, but to possess stronger activity against isoforms involved in other important pathologies, for example, obesity, cancer, epilepsy and hypertension. AREAS COVERED The class of clinically used diuretics, with CA inhibitory properties, is the main topic of the review. A patent literature review covering the period from 2005 to 2013 is presented. EXPERT OPINION This section presents an overview of the patent literature in the sulfonamide diuretic field. Most of the patents deal with the combination of diuretic sulfonamide CA inhibitors with other agents useful in the management of cardiovascular diseases and obesity. Such combinations exert a better therapeutic activity compared to similar diuretics that do not inhibit CAs, raising the question of the polypharmacological and drug repositioning effects of these old drugs. These effects seem to be due to the potent inhibition of such drugs against CA isoforms present in kidneys and blood vessels, which explain both the blood pressure lowering effects as well as organ-protective activity of the drugs. An explanation of these data is provided by the fact that inhibition of the renal CAs leads to a large increase of the nitrite excretion in urine, suggesting that renal CAs are involved in nitrite reabsorption in humans. Important lessons for the drug design of sulfonamide CA inhibitors (CAIs) can be drawn from these data.

Abstract
It is important to understand the molecular mechanisms underlying neuron death following stroke in order to develop effective neuroprotective strategies. Since studies on human stroke are extremely limited due to the difficulty in collecting post-mortem tissue at different time points after the onset of stroke, brain ischaemia research focuses on information derived from in-vitro models of neuronal death through ischaemic injury [1]. This review aims to provide an update on the different in-vitro stroke models with brain microvascular endothelial cells that are currently being used. These models provide a physiologically relevant tool to screen potential neuroprotective drugs in stroke and to study the molecular mechanisms involved in brain ischaemia.

Abstract
Variations in diuretic-mediated inhibition of carbonic anhydrase-dependent chloride transport in platelets and vascular smooth muscle could account for the contrasting efficacy of the thiazide and thiazide-like diuretics in reducing cardiovascular morbidity in patients with hypertension. We assessed platelet carbonic anhydrase activity and catecholamine-induced platelet aggregation in the presence of a thiazide and a “thiazide-like” inhibitor of the sodium-chloride cotransporter. Individual variation in platelet carbonic anhydrase activity correlated with contrasting sensitivity to epinephrine-mediated platelet aggregation. Both chlorthalidone, which potently inhibits platelet carbonic anhydrase, and bendroflumethiazide, which has much less effect on this enzyme, increased the amount of epinephrine needed to induce platelet aggregation when compared with the absence of a diuretic. However, chlorthalidone was significantly more effective than bendroflumethiazide in reducing epinephrine-mediated platelet aggregation. Chlorthalidone also induced marked changes in the number of gene transcripts for two proteins that mediate angiogenesis and vascular permeability, vascular endothelial growth factor C and transforming growth factor-β3; chlorthalidone and bendroflumethiazide had contrasting effects on the expression of vascular endothelial growth factor C. Chlorthalidone and bendroflumethiazide reduced vascular permeability to albumin, but only chlorthalidone increased angiogenesis. Thiazides and thiazide-like diuretics can comparably reduce blood pressure, but the drugs in this class are not all alike. It can be suggested from our findings that thiazide and thiazide-like diuretics vary in their pleiotropic effects on platelets and in the vasculature, and these differences could explain the contrasting ability of these drugs to reduce cardiovascular morbidity despite comparable reduction in blood pressure.

Abstract
Hypoxia and post-hypoxic reoxygenation induces disruption of the blood-brain barrier (BBB). Alterations of the BBB function after hypoxia/reoxygenation (H/R) injury remain unclear. Cyclosporin A (CsA), a potent immunosuppressant, induces neurotoxic effects by entering the brain, although the transport of CsA across the BBB is restricted by P-glycoprotein (P-gp), a multidrug efflux pump, and tight junctions of the brain capillary endothelial cells. The aim of this study was to evaluate whether the BBB after H/R damage is vulnerable to CsA-induced BBB dysfunction. We attempted to establish a pathophysiological BBB model with immortalized mouse brain capillary endothelial (MBEC4) cells. The effects of CsA on permeability and P-gp activity of the MBEC4 cells were then examined. Exposure to hypoxia for 4 h and reoxygenation for 1 h (H/R (4 h/1 h)) produced a significant decrease in P-gp function of MBEC4 cells, without changing cell viability and permeability for sodium fluorescein and Evan's blue-albumin at 7 days after H/R (4 h/1 h). CsA-induced hyperpermeability and P-gp dysfunction in MBEC4 monolayers at 7 days after H/R (4 h/1 h) were exacerbated. The possibility that CsA penetrates the BBB with incomplete functions in the vicinity of cerebral infarcts to induce neurotoxicity has to be considered.
