A systematic CRISPR screen defines mutational mechanisms underpinning signatures caused by replication errors and endogenous DNA damage.
Mutational signatures are imprints of pathophysiological processes arising through tumorigenesis. We generated isogenic CRISPR-Cas9 knockouts (Î) of 43 genes in human induced pluripotent stem cells, cultured them in the absence of added DNA damage, and performed whole-genome sequencing of 173 subclones. ÎOGG1, ÎUNG, ÎEXO1, ÎRNF168, ÎMLH1, ÎMSH2, ÎMSH6, ÎPMS1, and ÎPMS2 produced marked mutational signatures indicative of being critical mitigators of endogenous DNA modifications. Detailed analyses revealed mutational mechanistic insights, including how 8-oxo-dG elimination is sequence-context-specific while uracil clearance is sequence-context-independent. Mismatch repair (MMR) deficiency signatures are engendered by oxidative damage (C>A transversions), differential misincorporation by replicative polymerases (T>C and C>T transitions), and we propose a 'reverse template slippage' model for T>A transversions. ÎMLH1, ÎMSH6, and ÎMSH2 signatures were similar to each other but distinct from ÎPMS2. Finally, we developed a classifier, MMRDetect, where application to 7,695 WGS cancers showed enhanced detection of MMR-deficient tumors, with implications for responsiveness to immunotherapies
(Re)theorising laddish masculinities in higher education
In the context of renewed debates and interest in this area, this paper reframes the theoretical agenda around laddish masculinities in UK higher education, and similar masculinities overseas. These can be contextualised within consumerist neoliberal rationalities, the neoconservative backlash against feminism and other social justice movements, and the postfeminist belief that women are winning the âbattle of the sexesâ. Contemporary discussions of âlad cultureâ have rightly centred sexism and menÂčs violence against women: however, we need a more intersectional analysis. In the UK a key intersecting category is social class, and there is evidence that while working class articulations of laddism proceed from being dominated within alienating education systems, middle class and elite versions are a reaction to feeling dominated due to a loss of gender, class and race privilege. These are important differences, and we need to know more about the conditions which shape and produce particular performances of laddism, in interaction with masculinities articulated by other social groups. It is perhaps unhelpful, therefore, to collapse these social positions and identities under the banner of âlad cultureâ, as has been done in the past
Queer Asian Subjects: Transgressive Sexualities and Heteronormative Meanings
This special issue of Asian Studies Review explores comparatively the production and transformation of gender and sexual subjectivities across and beyond South and Southeast Asia. More specifically, papers in this special issue disclose the complex intersections of ethnicity, race, class, gender, religion and nationality through which sexual subjectivities are formed and subject positions inhabited within and across these regions. By tracing the transnational movement of people and the circulation of images and ideas, their appropriations and effects, the papers in this volume reveal mutable and multiple sexual subjectivities that are no longer fixed in place, even as state discourses, hegemonic meanings and individual actors work to attach specific meanings to particular bodies. In this special issue we ask, what are the effects of migration, forced and chosen, on forms and formulations of gender and sexuality for people's embodied and discursive entanglements? How do spatial and temporal, as well as religious, economic and political changes alter and foreclose some kinds of intimacies and subjectivities even as they open and enable others? What are the social and cultural processes through which heteronormativity is articulated, enforced, transgressed and challenged
From West Indies to East Indies: Archipelagic Interchanges
In this paper, I work to rethink notions of comparison and area studies by viewing my ethnographic work in Indonesia through the lens of theories developed by anthropologists working in the Caribbean region. In bringing 'East Indies' and 'West Indies' together in this way, I explore the possibility of reconfigured networks of citation, collaboration and interchange that might help anthropology respond in new ways to contemporary dynamics of globalisation. © 2006 Copyright Discipline of Anthropology and Sociology, The University of Western Australia
Globalization and change among the hijras of South Asia
Drawing on the anthropological fieldwork of both authors, this article examines the hijras of India and Bangladesh, emphasizing the changes in their traditional religious and political roles and identities, from ancient times until the present. While the most popular common understanding of the hijras, who are found in India, Bangladesh, and Pakistan, is that of a third sex or third gender, they are now also characterized as transgender both within South Asia and internationally. Ancient Hindu mythology provides the basic context for the hijra role in South Asia, but Islam is also critical to their social organization, identities, and present culture. Culture contact predating todayâs globalization has played an important role in hijra identity, beginning with their role as eunuchs in the Mughul Empire, through British colonialism, anthropological ethnography, and the internet and global social media. Hijra identity has now moved from an exclusive identification with the religious ritual of emasculation, to a global identity merging with LGBT activism. In addition, globally connected NGOS advocating human rights and HIV/AIDS related activism as well as transnational connections between hijras in South Asia and transgender groups in other parts of the world are now also central in hijra lives. In addition, partly through ethnography, gender theory, international tourism, and global media, the previously dominant binary Western sex/gender ideology is changing to a multiple and fluid gender ideology, both internationally and in South Asia. These global connections have resulted in increasing rights for hijras in India, Bangladesh, and Pakistan, including political, economic, and medical rights, through national legalization of hijras as a third gender
