Ca2+/CaM-stimulated proteins, including the family of multifunctional Ca2+/CaM-stimulated protein kinases (CaMK), have also been identified as mediators of cell cycle progression. CaMKII is the best-characterized member of this family, and is regulated by multi-site phosphorylation and targeting. Using pharmacological inhibitors that were believed to be specific for CaMKII , CaMKII has been implicated in every phase of the cell cycle. However, these ‘specific’ inhibitors also produce effects on other CaMKs. These additional effects are usually ignored, and the effects of the inhibitors are normally attributed to CaMKII without further investigation. Using new specific molecular techniques, it has become clear that CaMKI is an important regulator of G₁, whereas CaMKII is essential for regulating G₂/M and the metaphase-anaphase transition. If the mechanisms controlling these events can be fully elucidated, new targets for controlling proliferative diseases may be identified.]]> Wed 11 Apr 2018 11:04:43 AEST ]]> Haemophilus influenzae infection drives IL-17-mediated neutrophilic allergic airways disease https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:14153 Wed 11 Apr 2018 10:56:29 AEST ]]> A high-throughput protocol for mutation scanning of the BRCA1 and BRCA2 genes https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:13893 Wed 11 Apr 2018 10:36:53 AEST ]]> A pharmacological approach to first aid treatment for snakebite https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:14381 Wed 11 Apr 2018 10:04:10 AEST ]]> A high-fat challenge increases airway inflammation and impairs bronchodilator recovery in asthma https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17958 Wed 11 Apr 2018 09:41:07 AEST ]]> Long term transcriptional reactivation of epigenetically silenced genes in colorectal cancer cells requires DNA hypomethylation and histone acetylation https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:13894 Wed 11 Apr 2018 09:40:23 AEST ]]> The sustained phase of Tyrosine hydroxylase activation in vivo https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17101 Wed 11 Apr 2018 09:35:27 AEST ]]> Association of PHB 1630 C > T and MTHFR 677 C > T polymorphisms with breast and ovarian cancer risk in BRCA1/2 mutation carriers: results from a multicenter study https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:25127 T (rs6917) polymorphism and the MTHFR 677 C>T (rs1801133) polymorphism, respectively.

Analysis that evaluated associations for breast and ovarian cancer simultaneously showed some evidence that BRCA1 mutation carriers who had the rare homozygote genotype (TT) of the PHB 1630 C>T polymorphism were at increased risk of both breast and ovarian cancer (HR 1.50, 95%CI 1.10–2.04 and HR 2.16, 95%CI 1.24–3.76, respectively). However, there was no evidence of association under a multiplicative model for the effect of each minor allele.

Once a stable level of responding was reached, lever pressing was extinguished. Animals were then tested for reinstatement and sacrificed immediately following the presentation of either the S or S+ discriminative stimuli, and Fos-protein expression was assessed in thalamic and epithalamic regions. Interestingly, significant variation was observed in reinstatement behaviour, allowing a comparison between high-reinstating (HR), low-reinstating (LR) and control animals. Compared with LR animals, HR animals exhibited increased Fos-protein expression in the PVT, intermediodorsal thalamus and the medial and lateral divisions of the habenula. Our data provide evidence that activation of thalamic and epithalamic nuclei is associated with propensity to reinstate to cocaine-seeking elicited by drug-related cues. We also build upon existing data highlighting the importance of the PVT in reinstatement behaviour.]]> Sat 24 Mar 2018 08:23:44 AEDT ]]> Emerging roles of pulmonary macrophages in driving the development of severe asthma https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:15983 50% of asthma-related healthcare costs.

Importantly, factors that are linked to the activation of pulmonary macrophages may contribute to glucocorticoid resistance and severe asthma. Here, we review recent advances in understanding the roles of pulmonary macrophages in the mechanisms of glucocorticoid resistance and the pathogenesis of severe asthma. We discuss the role of macrophage phenotype, infection, IFN-γ, LPS, associated signaling pathways, TNF-α, MIF, and other macrophage-associated factors.

Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals2,3, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk4. Modestly powered genome-wide association studies (GWAS)5-10 have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility11. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis.]]> Sat 24 Mar 2018 08:19:55 AEDT ]]> BRIP1, PALB2, and RAD51C mutation analysis reveals their relative importance as genetic susceptibility factors for breast cancer https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12510 Sat 24 Mar 2018 08:18:42 AEDT ]]> Developmental changes in pacemaker currents in mouse locus coeruleus neurons https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12355 Sat 24 Mar 2018 08:18:31 AEDT ]]> Effect of subchronic administration of tachykinin antagonists on response of guinea-pigs to mild and severe stress https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12344 Sat 24 Mar 2018 08:18:30 AEDT ]]> Clostridium difficile laboratory testing in Australia and New Zealand: national survey results and Australasian Society for Infectious Diseases recommendations for best practice https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:13301 Sat 24 Mar 2018 08:18:05 AEDT ]]> Cardiac repolarization variability in patients with postural tachycardia syndrome during graded head-up tilt https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12385 Sat 24 Mar 2018 08:18:01 AEDT ]]> Quantification of cardiorespiratory interactions based on joint symbolic dynamics https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12386 Sat 24 Mar 2018 08:18:01 AEDT ]]> Potassium accumulation between type I hair cells and calyx terminals in mouse crista https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:12449 40 mV shift of the K⁺ equilibrium potential and a rise in effective K⁺ concentration (>50 mM) in the intercellular space. Together these data suggest K⁺ accumulation in the intercellular space accounts for the different responses in isolated and embedded type I hair cells. To test this notion, we exposed the preparation to hyperosmotic solutions to enlarge the intercellular space. As predicted, the K⁺ accumulation effects were reduced; however, a fit of our data with a classic diffusion model suggested K⁺ permeability, rather than the intercellular space, had been altered by the hyperosmotic change. These results support the notion that under depolarizing conditions Substantial K⁺ accumulation occurs in the space between type I hair cells and calyx.

Other immune cells, particularly neutrophils, macrophages and dendritic cells, as well structural cells such as epithelial and airway smooth muscle cells also produce disease-associated cytokines in asthma. Increased levels of these immune cells and cytokines have been identified in clinical samples and their potential role in disease demonstrated in studies using mouse models of asthma. Clinical trials with inhibitors of cytokines such as interleukin (IL)-4, -5 and tumour necrosis factor-α have had success in some studies but not others. This may reflect the design of the clinical trials, including treatments regimes and the patient population included in these studies. IL-13, -9 and granulocyte-macrophage colony-stimulating factor are currently being evaluated in clinical trials or preclinically and the outcome of these studies is eagerly awaited. Roles for IL-25, -33, thymic stromal lymphopoietin, interferon-γ, IL-17 and -27 in the regulation of asthma are just emerging, identifying new ways to treat inflammation. Careful interpretation of results from mouse studies will inform the development and application of therapeutic approaches for asthma. The most effective approaches may be combination therapies that suppress multiple cytokines and a range of redundant and disconnected pathways that separately contribute to asthma pathogenesis. Astute application of these approaches may eventually lead to the development of effective asthma therapeutics.

Similarly, blockade of L-type Ca2+ channels by nifedipine (1 μM) reduced histamine (1 mM) induced responses by 43% and responses induced by electrical field stimulation by 77%. Application of cyclopiazonic acid (CPA) (10 μM) to inhibit Ca2+ reuptake to the sarcoplasmic reticulum enhanced both histamine-induced and electrical field stimulation induced responses to a small degree, while the addition of the inosotol triphosphate (IP3) receptor antagonist, 2-aminophenoxyethane borane (2-APB) (100 μM) inhibited histamine induced responses by 70% and electrical field stimulation induced responses by 57%. Ryanodine (1 μM) did not affect contractile responses to either histamine or electrical field stimulation, either in the absence or presence of 2-APB (100 μM).

Although the loss in activity of the M-phase kinase CDK1 is known to be an essential downstream event of this process, the contribution of phosphatases to arrest and meiotic resumption is less apparent, especially in mammals. Therefore, we explored the role of protein phosphatase 2A (PP2A) in mouse eggs using pharmacological inhibition and activation as well as a functionally dominant-negative catalytic PP2A subunit (dn-PP2Ac-L199P) coupled with live cell imaging. We observed that PP2A inhibition using okadaic acid induced events normally observed at fertilization: degradation of the APC/C substrates cyclin B1 and securin resulting from loss of the APC/C inhibitor Emi2. Although sister chromatids separated, chromatin remained condensed, and polar body extrusion was blocked as a result of a rapid spindle disruption, which could be ameliorated by non-degradable cyclin B1, suggesting that spindle integrity was affected by CDK1 loss. Similar cell cycle effects to okadaic acid were also observed using dominant-negative PP2Ac. Preincubation of eggs with the PP2A activator FTY720 could block many of the actions of okadaic acid, including Emi2, cyclin B1, and securin degradation and sister chromatid separation. Therefore, in conclusion, we used okadaic acid, dn-PP2Ac-L199P, and FTY720 on mouse eggs to demonstrate that PP2A is needed to for both continued metaphase arrest and successful exit from meiosis.]]> Sat 24 Mar 2018 08:04:35 AEDT ]]> Genome-wide association study identifies a possible susceptibility locus for endometrial cancer https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17481 Sat 24 Mar 2018 08:04:10 AEDT ]]> Maternal dietary intake of folate and vitamins B6 and B12 during pregnancy and the risk of childhood acute lymphoblastic leukemia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:21473 Sat 24 Mar 2018 08:03:41 AEDT ]]> Genome-wide association study identifies a common variant associated with risk of endometrial cancer https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17125 −10) that is also associated with risk of prostate cancer and is inversely associated with risk of type 2 diabetes.]]> Sat 24 Mar 2018 08:02:31 AEDT ]]> On cervical zygapophysial joint pain after whiplash https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17110 Sat 24 Mar 2018 08:02:27 AEDT ]]> Evidence that microglia mediate the neurobiological effects of chronic psychological stress on the medial prefrontal cortex https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17332 Sat 24 Mar 2018 08:01:51 AEDT ]]> Morphological, neurochemical and electrophysiological features of parvalbumin-expressing cells: A likely source of axo-axonic inputs in the mouse spinal dorsal horn https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17330 Sat 24 Mar 2018 08:01:51 AEDT ]]> Chromosomal, metabolic, environmental, and hormonal origins of aneuploidy in mammalian oocytes https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17343 Sat 24 Mar 2018 08:01:41 AEDT ]]> Establishing a rodent stroke perfusion computed tomography model https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17421 Sat 24 Mar 2018 08:01:37 AEDT ]]> Effect of maternal administration of allopregnanolone before birth asphyxia on neonatal hippocampal function in the spiny mouse https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:16516 A receptor, and that has anti-apoptotic and anti-excitotoxic actions, reducing brain damage in adult animal models of brain injury. We sought to determine if prophylactic treatment of the pregnant female with a single dose of this steroid could reduce birth asphyxia-induced losses in hippocampal function at 5 days of age (P5) in spiny mouse neonates (Acomys cahirinus). At 37 days gestation (term = 39 days) and 1 h before inducing birth asphyxia, spiny mice dams were injected subcutaneously (0.2 ml) with either 3 mg/kg allopregnanolone or 20% w/v β-cyclodextrin vehicle. One hour later, fetuses were either delivered immediately by caesarean section (control group) or exposed to 7.5 min of in utero asphyxia, causing acidosis and hypoxia. At P5, ex vivo hippocampal plasticity was assessed, or brains collected to determine cell proliferation (proliferating cell nuclear antigen; PCNA) or calcium channel expression (inositol trisphosphate receptor type 1; IP₃R1) using immunohistochemistry. Allopregnanolone partially prevented the decrease in long term potentiation at P5, and the asphyxia-induced increase in IP₃R1 expression in CA1 pyramidal neurons. There was no effect of allopregnanolone on the asphyxia induced impairment of the input/output (I/O) curve and paired-pulse facilitation (PPF). In control birth pups, maternal allopregnanolone treatment caused significant changes in short term post-synaptic plasticity and also reduced hippocampal proliferation at P5. These findings show that allopregnanolone can modulate hippocampal development and synaptic function in a normoxic or hypoxic environment, possibly by modifying calcium metabolism. Best practice for treatment dose and timing of treatment will need to be carefully considered.]]> Sat 24 Mar 2018 08:01:15 AEDT ]]> Pneumococcal vaccination may induce anti-oxidized low-density lipoprotein antibodies that have potentially protective effects against cardiovascular disease https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:20387 Sat 24 Mar 2018 07:58:09 AEDT ]]> Interleukin-13 (IL-13)/IL-13 receptor α1 (IL-13Rα1) signaling regulates intestinal epithelial cystic fibrosis transmembrane conductance regulator channel-dependent Cl<sup>−</sup> secretion https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17727 − ion conductance). Pharmacological analyses in vitro and in vivo determined that elevated Cl conductance is mediated by altered cystic fibrosis transmembrane conductance regulator expression and activity. Generation of iIL-13Tg/Il13rα1−/−, iIL-13Tg/Il13rα2−/−, and iIL-13Tg/Stat6−/− mice revealed that IL-13-mediated dysregulation of epithelial architecture and Cl conductance is dependent on IL-13Rα1 and STAT-6. These observations demonstrate a central role for the IL-13/IL-13Rα1 pathway in the regulation of intestinal epithelial cell Cl secretion via up-regulation of cystic fibrosis transmembrane conductance regulator, suggesting an important role for this pathway in secretory diarrhea.]]> Sat 24 Mar 2018 07:57:45 AEDT ]]> Animal models of psychogenic cardiovascular disorders: what we can learn from them and what we cannot https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17776 Sat 24 Mar 2018 07:57:41 AEDT ]]> Neuronal activity regulates expression of tyrosine hydroxylase in adult mouse substantia nigra pars compacta neurons https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17775 A receptors, high K⁺, DA receptors) also increased or decreased cellular TH immunoreactivity but decreased or increased, respectively, the number of TH+ cells in SNc. We conclude that in adult SNc neurons: (i) TH expression is activity-dependent and begins to change ~20 h following sustained changes in neuronal activity; (ii) ion-channels and receptors mediating cell-autonomous activity or synaptic input are equally potent in altering TH expression; and (iii) activity-dependent changes in TH expression are balanced by opposing changes in the number of TH+ SNc cells.]]> Sat 24 Mar 2018 07:57:41 AEDT ]]> New insights into the generation of Th2 immunity and potential therapeutic targets for the treatment of asthma https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17772 Sat 24 Mar 2018 07:57:40 AEDT ]]> Antigen-specific T-cell responses to a recombinant fowlpox virus are dependent on MyD88 and Interleukin-18 and independent of toll-like Receptor 7 (TLR7)- and TLR9-mediated innate immune recognition https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17737 Sat 24 Mar 2018 07:57:39 AEDT ]]> Inhibition of cardiac Ca²⁺ release channels (RyR2) determines efficacy of class I antiarrhythmic drugs in catecholaminergic polymorphic ventricular tachycardia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17743 -/- myocytes, the propafenone enantiomers and flecainide significantly reduced arrhythmogenic Ca²⁺ waves at clinically relevant concentrations, whereas Na⁺ channel inhibitors without RyR2 blocking properties did not. In Casq2-/- mice, 5 mg/kg R-propafenone or 20 mg/kg S-propafenone prevented exercise-induced CPVT, whereas procainamide (20 mg/kg) or lidocaine (20 mg/kg) were ineffective (n=5 to 9 mice, P<0.05). QRS duration was not significantly different, indicating a similar degree of Na⁺ channel inhibition. Clinically, propafenone (900 mg/d) prevented ICD shocks in a 22-year-old CPVT patient who had been refractory to maximal standard drug therapy and bilateral stellate ganglionectomy. RyR2 cardiac Ca²⁺ release channel inhibition appears to determine efficacy of class I drugs for the prevention of CPVT in Casq2-/- mice.

Diagnostic restriction enzyme analysis detected low-level mosaicism of the mutation in their mother. Sister pair 2 are half-sisters who share a mother and each has the missense PCDH19 mutation c.1019 A>G, N340S. The sequence chromatograph of their mother shows reduced signal for the same mutation. These data indicate maternal somatic and gonadal mosaicism of the PCDH19 mutation in both sister pairs. Phenotyping is suggestive of, and PCDH19 mutation detection is diagnostic for, the disorder EFMR in the affected girls. Conclusions: We show that gonadal mosaicism of a PCDH19 mutation in a parent is an important molecular mechanism associated with the inheritance of EFMR. This should be considered when providing genetic counseling for couples who have one affected daughter as they may risk recurrence of affected daughters and having sons at risk of transmitting EFMR.]]> Sat 24 Mar 2018 07:57:38 AEDT ]]> Chloride-led disruption of the intestinal mucous layer impedes Salmonella invasion: evidence for an 'enteric tear' mechanism https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17715 Sat 24 Mar 2018 07:57:27 AEDT ]]> Docosapentaenoic acid (22:5n-3): a review of its biological effects https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17785 Sat 24 Mar 2018 07:57:23 AEDT ]]> Diagnostic reliability in osteopathic medicine https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17759 Sat 24 Mar 2018 07:57:22 AEDT ]]> Autonomic control of the urogenital tract https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17975 Sat 24 Mar 2018 07:56:42 AEDT ]]> Effects of chronic omega-3 polyunsaturated fatty acid supplementation on human pulmonary vein and left atrial electrophysiology in paroxysmal atrial fibrillation https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17907 1 month before their procedure into a control group (n = 18) or a fish oil group (n = 18) in an unblinded fashion. The latter were supplemented with fish oil 6 g/day for a mean of 40 ± 12 days. Pulmonary venous and left atrial effective refractory periods (ERPs), PV conduction, and susceptibility to AF initiated within PVs were assessed. Compared to the control group, the fish oil group had (1) longer left-sided (p = 0.002) and right-sided (p = 0.001) pulmonary venous ERPs; (2) less dispersion of pulmonary venous ERPs (left PVs p = 0.001, right PVs p = 0.07); (3) longer left atrial ERPs (p = 0.02); (4) no difference in pulmonary venous conduction; (5) lower incidence of AF initiated from PVs during ERP testing (77% vs 31%, p = 0.02); and (6) prolongation of mean AF cycle length (p = 0.009) and shortest AF cycle length in PVs (p = 0.04). In conclusion, patients with PAF chronically supplemented with fish oils exhibit distinctive electrophysiologic properties including prolonged pulmonary venous and left atrial ERPs and decreased susceptibility to initiation AF from within PVs. These changes may in part explain the antifibrillatory effect of chronic omega-3 polyunsaturated fatty acid supplementation in patients with PAF.]]> Sat 24 Mar 2018 07:56:40 AEDT ]]> Gastrointestinal polyps in McCune Albright syndrome https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17903 Sat 24 Mar 2018 07:56:40 AEDT ]]> Economic burden of Parkinson's disease in Singapore https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17946 Sat 24 Mar 2018 07:56:30 AEDT ]]> Selegiline use is associated with a slower progression in early Parkinson's disease as evaluated by Hoehn and Yahr Stage transition times https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17949 Sat 24 Mar 2018 07:56:30 AEDT ]]> Blocking induction of T helper type 2 responses prevents development of disease in a model of childhood asthma https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:17925 Sat 24 Mar 2018 07:56:24 AEDT ]]> Dietary supplementation with n-3 PUFA does not promote weight loss when combined with a very-low-energy diet https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:19245 Sat 24 Mar 2018 07:54:57 AEDT ]]> Microglial activation in the injured and healthy brain: what are we really talking about?
