From Boys to Men Overview and Recommendations

The From Boys to Men Project was funded by the Economic and Social Research
Council to explore why some boys become domestic abuse perpetrators when
others do not. In so doing, it sought to establish what more could be done to
reduce the number of young men who become perpetrators. The study
involved three phases of data collection including: Phase 1 - a survey of 1203
school children aged 13-14; Phase 2 - focus groups with 69 young people aged
13-19; and Phase 3 - life history interviews with 30 young men, aged 16-21,
who had experienced domestic abuse as victims, perpetrators or witnesses.
Reports on all stages of the project are freely available on our website
www.boystomenproject.com.
This report provides a brief overview of what we found and what
recommendations follow from the project’s findings.

Novel microtubule-targeting agents, pyrrolo-1,5-benzoxazepines, induce apoptosis in multi-drug-resistant cancer cells

PURPOSE: The development of multi-drug resistance (MDR) due to the expression of members of the ATP binding cassette (ABC) transporter family is a major obstacle in cancer treatment. The broad range of substrate specificities associated with these transporters leads to the efflux of many anti-cancer drugs from tumour cells. Therefore, the development of new chemotherapeutic agents that are not substrates of these transporters is important. We have recently demonstrated that some members of a novel series of pyrrolo-1,5-benzoxazepine (PBOX) compounds are microtubule-depolymerising agents that potently induce apoptosis in several cancer cell lines and impair growth of mouse breast tumours. The aim of this current study was to establish whether PBOXs were capable of inducing apoptosis in cancer cells expressing either P-glycoprotein or breast cancer resistance protein (BCRP), two of the main ABC transporters associated with MDR.

METHODS: We performed in vitro studies to assess the effects of PBOXs on cell proliferation, cell cycle and apoptosis in human cancer cell lines and their drug-resistant substrains expressing either P-glycoprotein or BCRP. In addition, we performed a preliminary molecular docking study to examine interactions between PBOXs and P-glycoprotein.

RESULTS: We established that three representative PBOXs, PBOX-6, -15 and -16 were capable of inducing apoptosis in drug-resistant HL60-MDR1 cells (expressing P-glycoprotein) and HL60-ABCG2 cells (expressing BCRP) with similar potencies as in parental human promyelocytic leukaemia HL60 cells. Likewise, resistance to PBOX-6 and -16 was not evident in P-glycoprotein-expressing A2780-ADR cells in comparison with parent human ovarian carcinoma A2780 cells. Finally, we deduced by molecular docking that PBOX-6 is not likely to form favourable interactions with the substrate binding site of P-glycoprotein.

CONCLUSION: Our results suggest that pro-apoptotic PBOX compounds may be potential candidates for the treatment of P-glycoprotein- or BCRP-associated MDR cancers.

Dual targeting of tumour cells and host endothelial cells by novel microtubule-targeting agents, pyrrolo-1,5-benzoxazepines

PURPOSE: Some members of a novel series of pyrrolo-1,5-benzoxazepines (PBOXs) are microtubule-targeting agents capable of inducing apoptosis in a variety of human cancerous cells, hence, they are currently being developed as potential anti-cancer agents. The purpose of this study was to first characterise the activities of a novel PBOX analogue, PBOX-16 and then investigate the anti-angiogenic potential of both PBOX-16 and its prototype PBOX-6.

METHODS: The effects of PBOX-6 and -16 on cancerous cells (chronic myeloid leukaemia K562 cells and ovarian carcinoma A2780 cells) and primary cultured human umbilical vein endothelial cells (HUVECs) were examined by assessing cell proliferation, microtubular organisation, DNA analysis of cell cycle progression and caspase-3/7 activity. Their anti-angiogenic properties were then investigated by examining their ability to interfere with HUVEC differentiation into capillary-like structures and vascular endothelial growth factor (VEGF)-stimulated HUVEC migration.

RESULTS: PBOX-6 and -16 inhibited proliferation of K562, A2780 and HUVEC cells in a concentration-dependent manner. PBOX-16, confirmed as a novel depolymerising agent, was approximately tenfold more potent than PBOX-6. Inhibition of cell proliferation was mediated by G(2)/M arrest followed by varying degrees of apoptosis depending on the cell type; endothelial cells underwent less apoptosis than either of the cancer cell lines. In addition to the antitumourigenic properties, we also describe a novel antiangiogenic function for PBOXs: treatment with PBOXs inhibited the spontaneous differentiation of HUVECs into capillary-like structures when grown on a basement membrane matrix preparation (Matrigel™) and also significantly reduced VEGF-stimulated HUVEC migration.

CONCLUSION: Dual targeting of both the tumour cells and the host endothelial cells by PBOX compounds might enhance the anti-cancer efficacy of these drugs.

Framing Wrongs, Performing Rights in Northern Ireland: Toward a Butlerian Approach to Life in Abortion Strategising

Feminist strategising on abortion has been dominated by a “pro-choice” frame. Increasingly, however, pro-choice discourse is being viewed as inadequate to meet contemporary and complex feminist aims and analyses, in particular due to the individualising ontological framework upon which it appears to be based. The work of Judith Butler is one location where such concerns have been explored and an alternative approach based upon a renewed analysis of the concept of “life” has been asserted. Foregrounding the fundamental precariousness of intersubjective life and opening the socio-political conditions sustaining precarious life to democratic public engagement carries significant implications for feminist strategising for Butler, and envisages a reconceptualisation of debate on abortion. In this article Butler’s work on life will be combined with her theoretical tool of the frame to explore space which may exist within pro-choice strategising to potentially work towards such a renewed approach to life in social debate on abortion. This space may be used to rethink feminist strategising on abortion beyond pro-choice discourse, and presents an accessible starting point from which to do so. In carrying out this analysis insights will be drawn from feminist advocacy and activism in the contingent location of Northern Ireland where recent employment of a health frame and a rights frame demonstrate instances of pro-choice strategising which may be reiterated to shift feminist activism towards more radical engagement with life as a precarious social process demanding critical attention.

Gendered Violence and International Human Rights: Thinking Non-Discrimination Beyond the Sex Binary

The concept of non-discrimination has been central in the feminist challenge to gendered violence within international human rights law. This article critically explores non-discrimination and the challenge it seeks to pose to gendered violence through the work of Judith Butler. Drawing upon Butler’s critique of heteronormative sex/gender, the article utilises an understanding of gendered violence as effected by the restrictive scripts of sex/gender within heteronormativity to illustrate how the development of non-discrimination within international human rights law renders it ineffective to challenge gendered violence due to its own commitments to binarised and asymmetrical sex/gender. However, the article also seeks to encourage a reworking of non-discrimination beyond the heteronormative sex binary through employing Butler’s concept of cultural translation. Analysis via the lens of cultural translation reveals the fluidity of non-discrimination as a universal concept and offers new possibilities for feminist engagement with universal human rights.

The inclusion and juridification of victims on the Island of Ireland

Concern for crime victims has been a growing political issue in improving the legitimacy and success of the criminal justice system through the rhetoric of rights. Since the 1970s there have been numerous reforms and policy documents produced to enhance victims’ satisfaction in the criminal justice system. Both the Republic of Ireland and Northern Ireland have seen a sea-change in more recent years from a focus on services for victims to a greater emphasis on procedural rights. The purpose of this chapter is to chart these reforms against the backdrop of wider political and regional changes emanating from the European Union and the European Court of Human Rights, and to critically examine whether the position of crime victims has actually ameliorated.

While separated into two legal jurisdictions, the Republic of Ireland and Northern Ireland as common law countries have both grappled with similar challenges in improving crime victim satisfaction in adversarial criminal proceedings. This chapter begins by discussing the historical and theoretical concern for crime victims in the criminal justice system, and how this has changed in recent years. The rest of the chapter is split into two parts focusing on the Republic of Ireland and Northern Ireland. Both parts examine the provisions of services to victims, and the move towards more procedural rights for victims in terms of information, participation, protection and compensation. The chapter concludes by finding that despite being different legal jurisdictions, the Republic of Ireland and Northern Ireland have introduced many similar reforms for crime victims in recent years.

BAR domains as sensors of membrane curvature:the amphiphysin BAR structure

The BAR (Bin/amphiphysin/Rvs) domain is the most conserved feature in amphiphysins from yeast to human and is also found in endophilins and nadrins. We solved the structure of the Drosophila amphiphysin BAR domain. It is a crescent-shaped dimer that binds preferentially to highly curved negatively charged membranes. With its N-terminal amphipathic helix and BAR domain (N-BAR), amphiphysin can drive membrane curvature in vitro and in vivo. The structure is similar to that of arfaptin2, which we find also binds and tubulates membranes. From this, we predict that BAR domains are in many protein families, including sorting nexins, centaurins, and oligophrenins. The universal and minimal BAR domain is a dimerization, membrane-binding, and curvature-sensing module.

EpsinR an AP1/clathrin interacting protein involved in vesicle trafficking

EpsinR is a clathrin-coated vesicle (CCV) enriched 70-kD protein that binds to phosphatidylinositol-4-phosphate, clathrin, and the gamma appendage domain of the adaptor protein complex 1 (AP1). In cells, its distribution overlaps with the perinuclear pool of clathrin and AP1 adaptors. Overexpression disrupts the CCV-dependent trafficking of cathepsin D from the trans-Golgi network to lysosomes and the incorporation of mannose-6-phosphate receptors into CCVs. These biochemical and cell biological data point to a role for epsinR in AP1/clathrin budding events in the cell, just as epsin1 is involved in the budding of AP2 CCVs. Furthermore, we show that two gamma appendage domains can simultaneously bind to epsinR with affinities of 0.7 and 45 microM, respectively. Thus, potentially, two AP1 complexes can bind to one epsinR. This high affinity binding allowed us to identify a consensus binding motif of the form DFxDF, which we also find in gamma-synergin and use to predict that an uncharacterized EF-hand-containing protein will be a new gamma binding partner.

Reclaiming the Radical in Universal Human Rights: Universality as Universalisation

The universality of human rights has been a fiercely contested issue throughout their history. This article contributes to scholarly engagements with the universality of human rights by proposing a re-engagement with this concept in a way that is compatible with the aims of radical politics. Instead of a static attribute or characteristic of rights this article proposes that universality can be thought of as, drawing from Judith Butler, an ongoing process of universalisation. Universality accordingly emerges as a site of powerful contest between competing ideas of what human rights should mean, do or say, and universal concepts are continually reworked through political activity. This leads to a differing conception of rights politics than traditional liberal approaches but, moreover, challenges such approaches. This understanding of universality allows human rights to come into view as potentially of use in interrupting liberal regimes and, crucially, opens possibilities to reclaim the radical in rights.

Rethinking Prison Disciplinary Processes: A Potential Future for Restorative Justice

The movement for restorative justice (RJ) has struggled with marginalization on the soft end of the criminal justice system where the threat of net widening and iatrogenesis looms large. To realize the full potential of RJ as an alternative philosophy of justice, restorative practices need to expand beyond the world of adolescent and small-level offences into the deeper end of the justice system. Disciplinary hearings inside of adult prisons may be a strategic space to advance this expansion. This paper presents findings from a study of prison discipline in four UK prisons. The findings strongly suggest that in their current form, such disciplinary proceedings are viewed by prisoners as lacking in legitimacy. Although modelled after the adversarial system of the criminal court, the adjudications were instead universally derided as ‘kangaroo courts’, lacking in the basic elements of procedural justice. Based on these findings, we argue that restorative justice interventions may offer a viable redress to these problems of legitimacy which, if successful, would have ramifications that extend well beyond the prison walls.

TH2 and TH17 inflammatory pathways are reciprocally regulated in asthma

Increasing evidence suggests that asthma is a heterogeneous disorder regulated by distinct molecular mechanisms. In a cross-sectional study of asthmatics of varying severity (n = 51), endobronchial tissue gene expression analysis revealed three major patient clusters: TH2-high, TH17-high, and TH2/17-low. TH2-high and TH17-high patterns were mutually exclusive in individual patient samples, and their gene signatures were inversely correlated and differentially regulated by interleukin-13 (IL-13) and IL-17A. To understand this dichotomous pattern of T helper 2 (TH2) and TH17 signatures, we investigated the potential of type 2 cytokine suppression in promoting TH17 responses in a preclinical model of allergen-induced asthma. Neutralization of IL-4 and/or IL-13 resulted in increased TH17 cells and neutrophilic inflammation in the lung. However, neutralization of IL-13 and IL-17 protected mice from eosinophilia, mucus hyperplasia, and airway hyperreactivity and abolished the neutrophilic inflammation, suggesting that combination therapies targeting both pathways may maximize therapeutic efficacy across a patient population comprising both TH2 and TH17 endotypes.
