Alternative splicing in the DBD linker region of p63 modulates binding to DNA and iASPP in vitro.

Cell Death Dis

January 2025

Institute of Biophysical Chemistry and Center for Biomolecular Magnetic Resonance, Goethe University, 60438, Frankfurt, Germany.

The transcription factor p63 is expressed in many different isoforms as a result of differential promoter use and splicing. Some of these isoforms have very specific physiological functions in the development and maintenance of epithelial tissues and surveillance of genetic integrity in oocytes. The ASPP family of proteins is involved in modulating the transcriptional activity of the p53 protein family members, including p63.

Cellular communication through the dissemination of signal molecules is vital for tissue organisation and homeostasis. The mechanisms of signal spreading can include binding-protein-assisted transport, long membrane protrusions known as cytonemes, and exovesicles. Recent research indicates that cytonemes and exovesicles can not only transport ligands but also facilitate the regulated distribution of receptors, thereby enabling signal transduction in cells lacking endogenous receptors.

Introduction: The healthcare sector has great potential for promoting physical activity (PA) for chronic disease prevention, treatment and management; however, multiple adoption and implementation barriers exist, ranging from practice integration to information flow. In 2016, Exercise is Medicine Greenville (EIMG), a comprehensive clinic-to-community approach that involves PA assessment, recommendation and/or prescription and provider-based referral of patients to community-based PA programmes, was launched by Prisma Health in Greenville, South Carolina, USA. Since inception, variability has emerged in adoption and implementation, impacting patient reach, referral rates and engagement in the community-based PA programmes, highlighting the need for closer evaluation and refinement of strategies to maximise programme impact.

FAecal micRobiota transplantation in primary sclerosinG chOlangitis (FARGO): study protocol for a randomised, multicentre, phase IIa, placebo-controlled trial.

BMJ Open

January 2025

National Institute of Health and Care Research (NIHR) Birmingham Biomedical Research Centre (BRC) Center for Liver and Gastrointestinal Research, University of Birmingham, Birmingham, England, UK

Introduction: Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). The strong association between gut and liver inflammation has driven several pathogenic hypotheses to which the intestinal microbiome is proposed to contribute. Pilot studies of faecal microbiota transplantation (FMT) in PSC and IBD are demonstrated to be safe and associated with increased gut bacterial diversity.

Background: There is emerging evidence for the role of exercise in optimising function, quality of life (QoL) and reducing hospital length-of-stay if commenced prior to undergoing autologous stem cell transplantation (ASCT). A local pilot study of a prehabilitation and rehabilitation intervention during ASCT for myeloma patients indicated promising results and was adapted to translate into local clinical care. The aim of this report is to describe an overview of a newly implemented physiotherapist-led exercise prehabilitation and rehabilitation service delivered as part of the myeloma ASCT pathway, and present real-world findings related to changes in function and QoL.

Sex and psychedelics: a wide-lens look at a burgeoning field.

Med Humanit

January 2025

Department of History, University of Saskatchewan, Saskatoon, Saskatchewan, Canada.

In this article we initiate a conversation between scientific and humanities-oriented studies of sexuality and psychedelics. Drawing on three recent studies which indicate a positive connection between the use of psychedelics and sexual well-being, the article argues that taking account of sexuality as culturally produced, historically contingent and geographically specific would improve the reliability and efficacy of future studies. The need for socially and culturally attuned research grounded in contemporary sexual politics in this area is urgent, as in recent years-despite little reporting of sexuality in clinical research-the psychedelics field has had to grapple with the ethics of the relationship between psychedelic states and sexual interactions in therapeutic spaces and the 'underground'.
