mid Inhibition of the erythropoietin-producing receptor EPHB4 antagonizes androgen receptor overexpression and reduces enzalutamide resistance [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Prostate cancer (PCa) cells heavily rely on an active androgen receptor (AR) pathway for their survival. Enzalutamide (MDV3100) is a second-generation antiandrogenic drug that was approved by the Food and Drug Administration in 2012 to treat patients with castration-resistant prostate cancer (CRPC). However, emergence of resistance against this drug is inevitable, and it has been a major challenge to develop interventions that help manage enzalutamide-resistant CRPC. Erythropoietin-producing human hepatocellular (Eph) receptors are targeted by ephrin protein ligands and have a broad range of functions. Increasing evidence indicates that this signaling pathway plays an important role in tumorigenesis. Overexpression of EPH receptor B4 (EPHB4) has been observed in multiple types of cancer, being closely associated with proliferation, invasion, and metastasis of tumors. Here, using RNA-Seq analyses of clinical and preclinical samples, along with several biochemical and molecular methods, we report that enzalutamide-resistant PCa requires an active EPHB4 pathway that supports drug resistance of this tumor type. Using a small kinase inhibitor and RNAi-based gene silencing to disrupt EPHB4 activity, we found that these disruptions re-sensitize enzalutamide-resistant PCa to the drug both in vitro and in vivo. Mechanistically, we found that EPHB4 stimulates the AR by inducing proto-oncogene c-Myc (c-Myc) expression. Taken together, these results provide critical insight into the mechanism of enzalutamide resistance in PCa, potentially offering a therapeutic avenue for enhancing the efficacy of enzalutamide to better manage this common malignancy.

mid Iraq's Reconstruction: In Conversation with Governor of Anbar Ali Farhan Hamid By feedproxy.google.com Published On :: Mon, 09 Dec 2019 16:30:01 +0000 Invitation Only Research Event 18 December 2019 - 9:00am to 10:30am Chatham House | 10 St James's Square | London | SW1Y 4LE Event participants Ali Farhan Hamid, Governor of Anbar ProvinceChair: Dr Renad Mansour, Senior Research Fellow, Middle East and North Africa Programme, Chatham House In the aftermath of the liberation from ISIS, the government of Iraq was left to count the cost of three years of brutal conflict, only the most recent phase in the ongoing cycle of conflict and stabilization that has plagued Iraq for 16 years. While reconstruction has been a focus of both the Iraqi government and international policymakers since 2003, billions of dollars in pledged funds have continually failed to reach the places they are most needed. At this roundtable, Ali Farhan Hamid will discuss the efforts of his provincial government to rebuild the cities and towns worst-hit by the conflict. He will provide insights into the practical and structural impediments to reconstruction efforts in both Anbar and neighbouring provinces such as Ninewah where the worst damage was sustained under ISIS but where little in the way of reconstruction has been achieved thereby leaving the door open to the potential resurgence of conflict.The roundtable is part of the Chatham House Iraq Initiative.

mid How the Soleimani Assassination Will Reverberate Throughout the Middle East By feedproxy.google.com Published On :: Mon, 06 Jan 2020 12:59:23 +0000 6 January 2020 Dr Sanam Vakil Deputy Director and Senior Research Fellow, Middle East and North Africa Programme @SanamVakil Dr Renad Mansour Senior Research Fellow, Middle East and North Africa Programme; Project Director, Iraq Initiative @renadmansour Dr Lina Khatib Director, Middle East and North Africa Programme @LinaKhatibUK Regional experts examine how Iran benefits from the fallout of the killing, the implications for politics in Iraq and how Tehran might respond with its proxies in the region. 2020-01-06-Soleimani.jpg Protesters hold up an image of Qassem Soleimani during a demonstration in Tehran on 3 January. Photo: Getty Images. An unexpected bounty for IranSanam VakilThe assassination of Qassem Soleimani has been an unexpected bounty for the Islamic Republic at a time when Iran was balancing multiple economic, domestic and regional pressures stemming from the Trump administration’s maximum pressure campaign.Coming on the heels of anti-Iranian demonstrations in Iraq and Lebanon, and following Iran’s own November 2019 protests that resulted in a brutal government crackdown against its own people, the Soleimani killing has helped the Iranian government shift the narrative away from its perceived regional and domestic weaknesses to one of strength. The massive funeral scenes in multiple Iranian cities displaying unending waves of mourners chanting against the United States has provided the Islamic Republic with a unique opportunity to showcase its mobilizing potential. This potential is not limited to Iran but also extends to Iraq and Lebanon, where Tehran’s transnational summoning power has also been visible. The Iraqi parliamentary vote to end the American military presence is one early negative consequence. While the region awaits Iran’s response, further anti-American rallying cries will continue to reverberate. Domestically, Soleimani’s death and President Donald Trump’s continued provocations on Twitter, including threats to attack 52 Iranian cultural sites, are being used as a nationalist rallying cry. This sentiment should not be seen solely as Islamic or ideological, but rather an opportunity for the state to pivot to an Iranian-based nationalism that is more inclusive and empowering for much of the country’s disgruntled youth.Iran’s notoriously divided political factions have also unified in the face of this crisis. With parliamentary elections looming in February and turnout previously expected to be low, the political establishment is likely to use this crisis to mobilize voters in favour of conservative candidates. How Tehran chooses to respond to Qassem Soleimani’s death will very much determine its ability to continue to control the narrative and manage its swell of domestic and regional support. For these benefits to continue to manifest, it is important for Tehran to balance the mix of public sympathy and international anxiety and not overplay its hand in its quest for revenge.A reset for Iraqi politicsRenad MansourThe US strike which killed Qassem Soleimani and Abu Mehdi al-Muhandis has grave implications for Iraq. The act jeopardizes Iraq’s recently stabilized security situation, and threatens to reshape the country’s political environment, moving backwards to the days of anti-Americanism and sect-based mobilization. If Baghdad loses relations with the US and other diplomatic representations, it risks turning into a pariah state. Over the past few years, and notably since October 2019, young Iraqis have taken to the streets demanding reform and the downfall of the political establishment, and its main external backer Iran. The political establishment, including political parties and militias close to Tehran, failed to appease or suppress these protests. Now, these political elites are using the deaths of Muhandis and Soleimani to (re)gain popularity from their own population, by drawing on the old tool of anti-Americanism. Following the attacks, Shia populist cleric Muqtada al-Sadr – who until recently had called for an end to Iranian and pro-Iranian militia influence in Iraq – has called to revamp the Mehdi Army that he led until 2008 and is calling for ‘Islamic resistance’ to the US. In seeking to regain control of his former movement, he is coming closer to former Shia foes.For years, pro-Iranian groups attempted to push the US out of Iraq. Their calls often fell on deaf ears, as public opinion in Iraq did not consider the US as a threat and some even supported the US and international effort against ISIS. Following the attacks, however, anti-American voices have gained more ammunition.A complete American withdrawal would not only have direct security implications but force other countries and organizations, from European states to NATO, to reconsider their positions and role.Limited options for ‘revenge’ in the LevantLina KhatibIran’s use of Lebanon and Syria as spaces for revenge against the US is unlikely.On Sunday, Hezbollah leader Hassan Nasrallah vowed revenge for Soleimani’s death by singling out American soldiers as a target. However, Hezbollah’s options are limited. Lebanon is in the middle of wide-ranging protests against the country’s ruling political class, of which Nasrallah is a key figure.Unlike in 2006, when Hezbollah’s military actions against Israel rallied the public around it, today there is no public appetite for dragging Lebanon into a war. Were Hezbollah to instigate one, it would incur public anger, if only for the economic repercussions that would exacerbate an already severe financial crisis in Lebanon. Lebanon also does not have any US military bases that could be a target for Hezbollah.In theory, Hezbollah or other Iranian-backed groups could attack American bases in Syria. But these bases are staffed by multinational forces from the international anti-ISIS coalition. Attacking them would therefore put Iran in confrontation with other countries besides the US, which is not in Iran’s interest.Attacking US soldiers in northeast Syria would also go against Kurdish interests because it would weaken the anti-ISIS coalition front of which Kurdish forces are part. It would, furthermore, anger Arab tribes in the area, opening up possibilities for ISIS to take advantage of public dissent to stage a comeback. Iran would then find itself fighting on several fronts at once, which it does not have the capacity to handle. More likely, Iran’s allies and proxies in the Levant are going to engage in strong rhetoric without taking hasty actions. When a key Hezbollah leader, Imad Mughniyeh, was assassinated in Damascus on 2008, there were strong words and public vows to seek revenge for his killing, but ultimately there was no response.

In April 2020, UN Secretary General Antonio Guterres called for a global ceasefire in order for communities and states to focus efforts on responding to the coronavirus outbreak. The consequences of armed conflict – including displacement, detention, lack of access to health services and disrupted social infrastructures – mean that those in conflict-ridden areas are amongst the most vulnerable to the virus. Observing international humanitarian law (IHL) could be one way of safeguarding against, at least, the provision of vital medical supplies and personnel for vulnerable groups. Against the backdrop of a growing health and economic emergency that is otherwise dominating government agendas, how do we emphasise the importance of humanitarian action and guarantee - or improve - compliance?The panellists will discuss the remit and limitations of international humanitarian law and how the pandemic might complicate compliance.

Since assuming office, President Trump has withdrawn the US from the Joint Comprehensive Plan of Action, withdrawn troops from Syria, relocated the US embassy in Israel to Jerusalem and orchestrated the strike against ISIS leader Abu Bakr al-Baghdadi.Against a backdrop of Trump's inclination towards withdrawing from the region, countries across the Middle East are being rocked by protests, Turkey’s purchase of Russia’s S-400 missile has threatened to undermine cohesion within NATO and the much hoped for ceasefire in Libya between UN-backed government leader, Fayez al-Sarraj, and opposition leader, Khalifa Haftar, failed to materialize.In light of the upcoming US elections in November 2020, the future of US national security policy promises to be a prominent issue for the next administration. In this vein, the US and Americas Programme at Chatham House plans a yearlong focus on the pivotal US 2020 elections.At this event, Dr Kori Schake, director of foreign and defense policy studies at the American Enterprise Institute will discuss the future of US foreign policy towards the Middle East. How have domestic and party politics in the US – and the unfolding presidential campaign – shaped recent policy decisions by the Trump administration? Should we expect policy objectives in the Middle East to remain consistent or shift under a second Trump term? And what direction could US foreign policy towards the region take under a Democratic administration?Attendance at this event is by invitation only.

mid Determination of globotriaosylceramide analogs in the organs of a mouse model of Fabry disease [Lipids] By www.jbc.org Published On :: 2020-04-24T06:08:45-07:00 Fabry disease is a heritable lipid disorder caused by the low activity of α-galactosidase A and characterized by the systemic accumulation of globotriaosylceramide (Gb3). Recent studies have reported a structural heterogeneity of Gb3 in Fabry disease, including Gb3 isoforms with different fatty acids and Gb3 analogs with modifications on the sphingosine moiety. However, Gb3 assays are often performed only on the selected Gb3 isoforms. To precisely determine the total Gb3 concentration, here we established two methods for determining both Gb3 isoforms and analogs. One was the deacylation method, involving Gb3 treatment with sphingolipid ceramide N-deacylase, followed by an assay of the deacylated products, globotriaosylsphingosine (lyso-Gb3) and its analogs, by ultra-performance LC coupled to tandem MS (UPLC-MS/MS). The other method was a direct assay established in the present study for 37 Gb3 isoforms and analogs/isoforms by UPLC-MS/MS. Gb3s from the organs of symptomatic animals of a Fabry disease mouse model were mainly Gb3 isoforms and two Gb3 analogs, such as Gb3(+18) containing the lyso-Gb3(+18) moiety and Gb3(−2) containing the lyso-Gb3(−2) moiety. The total concentrations and Gb3 analog distributions determined by the two methods were comparable. Gb3(+18) levels were high in the kidneys (24% of total Gb3) and the liver (13%), and we observed Gb3(−2) in the heart (10%) and the kidneys (5%). These results indicate organ-specific expression of Gb3 analogs, insights that may lead to a deeper understanding of the pathophysiology of Fabry disease. Full Article

mid Combined Visual and Semi-quantitative Evaluation Improves Outcome Prediction by Early Mid-treatment 18F-fluoro-deoxi-glucose Positron Emission Tomography in Diffuse Large B-cell Lymphoma. By jnm.snmjournals.org Published On :: 2019-11-22T10:43:33-08:00 The purpose of this study was to assess the predictive and prognostic value of interim FDG PET (iPET) in evaluating early response to immuno-chemotherapy after two cycles (PET-2) in diffuse large B-cell lymphoma (DLBCL) by applying two different methods of interpretation: the Deauville visual five-point scale (5-PS) and a change in standardised uptake value by semi-quantitative evaluation. Methods: 145 patients with newly diagnosed DLBCL underwent pre-treatment PET (PET-0) and PET-2 assessment. PET-2 was classified according to both the visual 5-PS and percentage SUV changes (SUV). Receiver operating characteristic (ROC) analysis was performed to compare the accuracy of the two methods for predicting progression-free survival (PFS). Survival estimates, based on each method separately and combined, were calculated for iPET-positive (iPET+) and iPET-negative (iPET–) groups and compared. Results: Both with visual and SUV-based evaluations significant differences were found between the PFS of iPET– and iPET+ patient groups (p<0.001). Visually the best negative (NPV) and positive predictive value (PPV) occurred when iPET was defined as positive if Deauville score 4-5 (89% and 59%, respectively). Using the 66% SUV cut-off value, reported previously, NPV and PPV were 80 and 76%, respectively. SUV at 48.9% cut-off point, reported for the first time here, produced 100% specificity along with the highest sensitivity (24%). Visual and semi-quantitative SUV<48.9% assessment of each PET-2 gave the same PET-2 classification (positive or negative) in 70% (102/145) of all patients. This combined classification delivered NPV and PPV of 89% and 100% respectively, and all iPET+ patients failed to achieve or remain in remission. Conclusion: In this large consistently treated and assessed series of DLBCL, iPET had good prognostic value interpreted either visually or semi-quantitatively. We determined that the most effective SUV cut-off was at 48.9%, and that when combined with visual 5-PS assessment, a positive PET-2 was highly predictive of treatment failure. Full Article
mid Imaging P-glycoprotein Induction at the Blood-Brain Barrier of a Beta-Amyloidosis Mouse Model with 11C-Metoclopramide PET By jnm.snmjournals.org Published On :: 2019-12-05T10:37:41-08:00 P-glycoprotein (ABCB1) plays an important role at the blood-brain barrier (BBB) in promoting the clearance of neurotoxic beta-amyloid (Aß) peptides from the brain into the blood. ABCB1 expression and activity were found to be decreased in the brains of Alzheimer disease (AD) patients. Treatment with drugs which induce cerebral ABCB1 activity may be a promising approach to delay the build-up of Aß deposits in the brain by enhancing the clearance of Aß peptides from the brain. The aim of this study was to investigate whether PET with the weak ABCB1 substrate radiotracer 11C-metoclopramide can measure ABCB1 induction at the BBB in a beta-amyloidosis mouse model (APP/PS1-21 mice) and in wild-type mice. Methods: Groups of wild-type and APP/PS1-21 mice aged 50 or 170 days underwent 11C-metoclopramide baseline PET scans or scans after intraperitoneal treatment with the rodent pregnane X receptor (PXR) activator 5-pregnen-3β-ol-20-one-16α-carbonitrile (PCN, 25 mg/kg) or its vehicle over 7 days. At the end of the PET scans, brains were harvested for immunohistochemical analysis of ABCB1 and Aß levels. In separate groups of mice, radiolabeled metabolites of 11C-metoclopramide were determined in plasma and brain at 15 min after radiotracer injection. As an outcome parameter of cerebral ABCB1 activity, the elimination slope of radioactivity washout from the brain (kE,brain) was calculated. Results: PCN treatment resulted in an increased clearance of radioactivity from the brain as reflected by significant increases in kE,brain (from +26% to +54% relative to baseline). Immunohistochemical analysis confirmed ABCB1 induction in the brains of PCN-treated APP/PS1-21 mice with a concomitant decrease in Aß levels. There was a significant positive correlation between kE,brain values and ABCB1 levels in the brain. In wild-type mice, a significant age-related decrease in kE,brain values was found. Metabolite analysis showed that the majority of radioactivity in the brain was composed of unmetabolized 11C-metoclopramide in all animal groups. Conclusion: 11C-metoclopramide can measure ABCB1 induction in the mouse brain without the need to consider an arterial input function and may find potential application in AD patients to non-invasively evaluate strategies to enhance the clearance properties of the BBB.

mid Comparative profiling and comprehensive quantification of stratum corneum ceramides in humans and mice by LC-MS/MS [Research Articles] By feedproxy.google.com Published On :: 2020-04-07T07:33:32-07:00 Ceramides are the predominant lipids in the stratum corneum (SC) and are crucial components for normal skin barrier function. Although the composition of various ceramide classes in the human SC has been reported, that in mice is still unknown, despite mice being widely used as animal models of skin barrier function. Here, we performed LC–MS/MS analyses using recently available ceramide class standards to measure 25 classes of free ceramides and 5 classes of protein-bound ceramides from the human and mouse SC. Phytosphingosine-type ceramides (P-ceramides) and 6-hydroxy sphingosine-type ceramides (H-ceramides), which both contain an additional hydroxyl group, were abundant in human SC (35% and 45% of total ceramides, respectively). In contrast, in mice, P-ceramides and H-ceramides were present at ~1% and undetectable levels, respectively, and sphingosine-type ceramides accounted for ~90%. In humans, ceramides containing α-hydroxy FA were abundant, whereas ceramides containing β-hydroxy FA (B-ceramides) or -hydroxy FA were abundant in mice. The hydroxylated β-carbon in B-ceramides was in the (R)-configuration. Genetic knockout of β-hydroxy acyl-CoA dehydratases in HAP1 cells increased B-ceramide levels, suggesting that β-hydroxy acyl-CoA, an FA-elongation cycle intermediate in the endoplasmic reticulum, is a substrate for B-ceramide synthesis. We anticipate that our methods and findings will help to elucidate the role of each ceramide class in skin barrier formation and in the pathogenesis of skin disorders. Full Article
