Non-alcoholic fatty liver disease (NAFLD) is associated with mutations in lipopolysaccharide-binding protein ( LBP), but the underlying epigenetic mechanisms remain understudied. Herein, LBP-/- rats with NAFLD were established and used to conduct integrative targeting-active enhancer histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation coupled with high-throughput and transcriptomic sequencing analysis to explore the potential epigenetic pathomechanisms of active enhancers of NAFLD exacerbation upon LBP deficiency. Notably, LBP-/- reduced the inflammatory response but markedly aggravated high-fat diet (HFD)-induced NAFLD in rats, with pronounced alterations in the histone acetylome and regulatory transcriptome. In total, 1 128 differential enhancer-target genes significantly enriched in cholesterol and fatty acid metabolism were identified between wild-type (WT) and LBP-/- NAFLD rats. Based on integrative analysis, CCAAT/enhancer-binding protein β (C/EBPβ) was identified as a pivotal transcription factor (TF) and contributor to dysregulated histone acetylome H3K27ac, and the lipid metabolism gene SCD was identified as a downstream effector exacerbating NAFLD. This study not only broadens our understanding of the essential role of LBP in the pathogenesis of NAFLD from an epigenetics perspective but also identifies key TF C/EBPβ and functional gene SCD as potential regulators and therapeutic targets.

Abstract:Blackface minstrelsy was the dominant form of mass entertainment for over a century, from the 1840s through the 1940s. In Canada, there has been little scholarly research into the topic but for the work of Stephen Johnson and, in recent years, the works I have published on the subject. One of the reasons blackface has been understudied is the dearth of attention paid to histories of slavery. By exploring the history of casting blackface productions, both ‘white’ minstrelsy (white performers blackening up to imitate the song and dance of African-Americans) and ‘Black’ minstrelsy (Black performers in and out of blackface performing caricatures of themselves in front of majority-white audiences), we gain an understanding of how these shows were produced, and what audiences found appealing about them. Canada has produced its own blackface stars, like Colin ‘Cool’ Burgess (1840–1905) and Calixa Lavallée (1842–1891), both of whom toured the United States and Canada in the late nineteenth century and who not only performed in blackface but also produced songs, some of which are still known today, like “O Canada,” the Canadian national anthem, composed by Lavallée in 1880. Additionally, what the history of casting blackface in Canada shows is a long-standing desire among white audiences for depictions of the American Plantation South that often included the participation of local actors like playwright and writer Charles Wesley Handscomb (1867–1906), who moved to Winnipeg in 1879, who were often cast in touring minstrel productions to sing in blackface.

Abstract:In this review of the 2022 performance of Our Fathers, Sons, Lovers and Little Brothers, Andrea A. Davis and Carl E. James, from their respective disciplines in Black literary and cultural studies, education, and sociology, engage in a conversation about Makambe K. Simamba’s play. In their conversation, they unpack questions about Black spirituality, the social construction of gender as a raced category, and the difficulty of articulating anti-Black racism in Canada. Their conversation is framed by a critical analysis that locates the play’s action within an understanding of Black community that exceeds national and geographical boundaries, connecting Black experiences in the United States and Canada.

Abstract:Interdependent Magic, curated by Jessica Watkin, is the first anthology of plays by disabled Canadian playwrights from Playwrights Canada Press. It includes pieces by Alex Bulmer, the Boys in Chairs Collective, Syrus Marcus Ware, and Chris Dodd, as well as an interview with Niall McNeil. In this review, Kelsie Acton considers the ways in which the strength of this volume lies not just in the quality and diversity of playwriting featured but also in the care the editor has taken in framing the work. Watkin offers two introductions, one aimed at audiences familiar with disability justice and disability arts and the other aimed at audiences new to disability culture. Interdependent Magic acknowledges the diversity of disabled playwrights in Canada and the diversity of audiences who will read their work.
摘要:杰西卡·沃特金策划的《相互依存的魔法》是加拿大剧作家出版社的第一本加拿大残疾剧作家戏剧选集。其中包括Alex Bulmer、Boys in Chairs Collective、Syrus Marcus Ware和Chris Dodd的作品,以及对Niall McNeil的采访。在这篇综述中,凯尔西·阿克顿认为,这本书的优势不仅在于剧本写作的质量和多样性,还在于编辑在构思作品时所采取的谨慎态度。Watkin提供了两个介绍,一个面向熟悉残疾司法和残疾艺术的观众,另一个面向新接触残疾文化的观众。《相互依存的魔法》承认加拿大残疾剧作家的多样性以及阅读他们作品的观众的多样性。

Abstract:The inaugural CoMotion: A Deaf and Disability Arts Festival at Toronto’s Harbourfront Centre from 20 April to 1 May 2022, curated by blind theatre artist Alex Bulmer, presented six live and four digital performances, six visual arts exhibitions, and four panels and conversations, a Q&A with Bulmer, and an “every-body-can-dance” workshop. The festival featured blind, Deaf, and neurodivergent artists, amputees, stutterers, and those with chronic pain or fatigue or with degenerative diseases. Some of the work served primarily a community-building function, some adhered to the familiar disability genres of the tragic or inspirational, but most celebrated the disability artist’s refusal of both exclusion and inclusion. The best of the festival’s offerings were not about overcoming disabilities but about joyful, if clear-eyed, engagement with the opportunities disability can offer.

ABSTRACT:Political Adaptation in Canadian Theatre, by Kailin Wright, is an excellent addition to the discourse on theatre adaptations. Wright applies theories of adaptation, identification, performance, Indigenous dramaturgy, and speech acts to define political adaptation as distinct from adaptation “proper”. She contends that political adaptations activate publics or, in her terms, “dispublics,” toward changed perspectives on inherited narratives. Seminal to her argument is Michel Pêcheux’s tripartite terminology, which describes the relationship of the spectator to mainstream culture as identification, counteridentification, and disidentification.
