BACKGROUND: Infantile hemangiomas (IH) with functional or cosmetic concerns necessitate systemictreatment for which propranolol is the preferred treatment. However, the mechanism ofaction is unknown. Mouse models suggest the angiopoietin-2 (Ang2)/Tie-2 system isimplicated. Ang2 can promote endothelial growth or induce apoptosis depending on thepresence of vascular endothelial growth factor (VEGF). This pilot study investigates thesaliva Ang2 levels in infants with IH treated with and without systemic propranolol...

Obstructive sleep apnea (OSA), which involves chronic, intermittent hypoxia (CIH), is a major risk factor for developing atrial fibrillation (AF). Whether or not CIH alone alters cardiac mechanisms to support AF is unknown. This study investigated the effects of CIH on atrial electrophysiology and arrhythmia vulnerability, and evaluated the role of autonomics in CIH promotion of AF. Adult male Sprague-Dawley rats were exposed to 8h/day of CIH or normoxia for 7 days. Following exposure, rats were anesthetized for intracardiac electrophysiological studies...

Both sunitinib, a multi-target tyrosine kinase inhibitor (TKI) and propranolol, a non-selective β-blocker, have proven therapeutic effects on malignant melanoma (MM). This study reports a synergistic effect of propranolol and sunitinib upon A375, P8 MM cell lines and mice xenografts. Cell viability assays detected a significant decrease of sunitinib IC50 in combination with propranolol, which was confirmed by a colony formation assay. Western blot showed that propranolol and sunitinib combination significantly down-regulated phospho-Rb, phospho-ERK, Cyclin D1, and Cyclin E, but had no effect on Bax, Bcl-2, or cleaved PARP expression...

Psoriasis is a chronic inflammatory skin disease characterized by red, scaly and raised plaques. Thus far, T-cell infiltration is one of the most prominent pathogenic triggers, however, the exact molecular mechanisms underlying psoriasis have not been clearly established. Sphingolipid sphingosine-1-phosphate (S1P) is a lysophospholipid regulator modulating a variety of immune cell trafficking via interactions with its cognate receptors, S1P1-5. Activation of S1P signaling has recently emerged as a novel therapeutic avenue for psoriasis treatment...

Recent studies have led to some groundbreaking findings regarding the use of medications for the support of behavioral health in dogs and cats. Despite tantalizing results, these studies should be viewed in light of their limitations. Consequently, the results of these studies should be applied in the clinical setting with caution and with a full understanding of the potential pros and cons of using these medications. A review of the research available on trazodone, clonidine, detomidine, dexmedetomidine, propranolol, pindolol, maropitant, memantine, venlafaxine, and gabapentin discusses these pros and cons and highlights key points regarding their clinical use and application...

Acrylic pressure sensitive adhesives (PSAs) are widely used in transdermal drug delivery system (TDDS). However, there was little research about the quantitative relationship between drug release and drug-PSAs interaction. In this study, five acrylic PSAs with different molar fraction of carboxyl group were designed and synthesized. Propranolol (PRO) was used as model drug to evaluate release profiles in the PSAs in vitro and in vivo. The drug release percent in the PSAs were 81.66, 78.22, 51.66, 21.81 and 11...

The therapeutic efficacy of the synthetic β-adrenergic receptor blocker, propranolol, for the treatment of post-traumatic stress disorder (PTSD) is currently being debated. Mixed results have been published regarding propranolol's ability to disrupt the consolidation and reconsolidation of memories. Here, we use the invertebrate model Lymnaea to study propranolol's ability to disrupt consolidation of memories formed under varying various types of stress which cause differing degrees of emotional memory. We show that when propranolol is administered immediately following operant conditioning, only the consolidation process of memories enhanced by individual stressors (i...

Drug absorption after nasal application is dependent on drug clearance from the nasal cavity, which is determined by nasal mucociliary clearance (MC). We previously developed an in vitro method to evaluate MC via the translocation velocity of fluorescent microspheres (VFMS) applied to excised rat nasal mucosa. In the present study, the relationship between in vivo nasal MC and in vitro VFMS was examined to optimize our PK model for the prediction of nasal drug absorption. Appropriate inhibitors (propranolol and atropine) and enhancers (terbutaline and acetylcholine chloride) of MC were utilized to modify MC...

BACKGROUND: Oral propranolol is the gold-standard to treat infantile hemangiomas. There is better efficacy and a lower risk of sequelae if therapy is started before the end of the growth phase, but most children are referred too late. Herein, we report the first study to investigate the delay and its associated factors when referring infants with infantile hemangiomas that need propranolol therapy. OBJECTIVES: The primary objective was to determine the delay in referral (time between age at referral [first phone contact] and the optimal age for referral (fixed at 75 days)...

Essential tremor (ET) is currently classified as a syndrome rather than a unique disease, primarily involving monosymptomatic action tremor in both hands. Different etiologies are presumed to underlie this condition. Currently only a few monogenetic conditions are known to present with this syndrome. If accompanied by additional symptoms that do not in themselves constitute a new syndrome, such as abnormal tandem gait or postures, the syndrome should be diagnosed as "ET plus". ET is associated with abnormal rhythmic activation of the cerebello-thalamo-cortical tremor circuit...

Modelling disease with hPSCs is hindered because the impact on cell phenotype from genetic variability between individuals can be greater than from the pathogenic mutation. While 'footprint-free' Cas9/CRISPR editing solves this issue, existing approaches are inefficient or lengthy. Here, a simplified PiggyBac strategy shortened hPSC editing by 2 weeks and required one round of clonal expansion and genotyping rather than two, with similar efficiencies to the longer conventional process. Success was shown across 4 cardiac-associated loci (ADRB2, GRK5, RYR2, ACTC1) by genomic cleavage and editing efficiencies of 8-93% and 8-67%, respectively, including mono- and/or bi-allelic events...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant hereditary disorder resulting in vascular dysplasia and formation of arteriovenous malformations. Recurrent epistaxis is a hallmark of the disease. An array of medical therapies are used in this patient population, but robust evidence-based recommendations regarding the medical treatment of epistaxis are lacking. This systematic review was performed to look at the current literature and make meaningful evidence-based recommendations...

An increasing amount of evidence indicates that the inhibition of β adrenergic signaling can result in the inhibition of tumor growth. However, the role of propranolol in liver cancer and the underlying mechanism remain to be elucidated. The present study aimed to investigate the role of propranolol in liver cancer cell lines and provide evidence for further clinical study. Propranolol was added at different concentrations to HepG2 and HepG2.2.15 liver cancer cells and HL‑7702 normal human liver cells. The proliferation of the cell lines was monitored by live‑cell imaging at a range of time intervals...

Propranolol has been the first-line treatment for alarming hemangiomas. However, some hemangiomas are propranolol-resistant. The authors reported 1 propranolol-resistant hemangioma which was treated with intralesional bleomycin injections. Sixteen months after 3 injections, the lesion still remained stable. Its potential mechanism was clarified by ultrasonic monitoring. Intralesional bleomycin injection can be considered an ideal option in treating propranolol-resistant hemangiomas.

Elevated body iron stores are associated with hypertension progression, while hypertension is associated with elevated plasma catecholamine levels in patients. However, there is a gap in our understanding of the connection between catecholamines and iron regulation. Hepcidin is a key iron-regulatory hormone, which maintains body iron balance. In the present study, we investigated the effects of adrenaline (AD) and norepinephrine (NE) on hepatic hepcidin regulation. Mice were treated with AD, NE, phenylephrine (PE, α1-adrenergic receptor agonist), prazosin (PZ, α1-adrenergic receptor antagonist), and/or propranolol (Pro, β-adrenergic receptor antagonist)...

The non-canonical NF-κB signaling (RelB/p52) pathway drives pro-labor genes in the human placenta, including corticotropin-releasing hormone (CRH) and cyclooxygenase-2 (COX-2), making this a potential therapeutic target to delay onset of labor. Here we sought to identify small molecule compounds from a pre-existing chemical library of orally active drugs that can inhibit this NF-κB signaling, and in turn, human placental CRH and COX-2 production. We used a cell-based assay coupled with a dual-luciferase reporter system to perform an in vitro screening of a small molecule library of 1,120 compounds for inhibition of the non-canonical NF-κB pathway...
