Exploiting the Stemness and Chemoresistance Transcriptome of Ewing Sarcoma to Identify Candidate Therapeutic Targets and Drug-Repurposing Candidates.

Outcomes for most patients with Ewing sarcoma (ES) have remained unchanged for the last 30 years, emphasising the need for more effective and tolerable treatments. We have hypothesised that using small-molecule inhibitors to kill the self-renewing chemotherapy-resistant cells (Ewing sarcoma cancer stem-like cells; ES-CSCs) responsible for progression and relapse could improve outcomes and minimise treatment-induced morbidities. For the first time, we demonstrate that ABCG1, a potential oncogene in some cancers, is highly expressed in ES-CSCs independently of CD133.

Understanding and Improving Older People's Well-Being through Social Prescribing Involving the Cultural Sector: Interviews from a Realist Evaluation.

Social prescribing is a non-clinical approach to addressing social, environmental, and economic factors affecting how people feel physical and/or emotionally. It involves connecting people to "community assets" (e.g.

Tailoring cultural offers to meet the needs of older people during uncertain times: a rapid realist review.

Background: Non-medical issues (e.g. loneliness, financial concerns, housing problems) can shape how people feel physically and psychologically.

The influence of hypoxia and energy depletion on the response of endothelial cells to the vascular disrupting agent combretastatin A-4-phosphate.

Combretastatin A-4 phosphate (CA4P) is a microtubule-disrupting tumour-selective vascular disrupting agent (VDA). CA4P activates the actin-regulating RhoA-GTPase/ ROCK pathway, which is required for full vascular disruption. While hypoxia renders tumours resistant to many conventional therapies, little is known about its influence on VDA activity.

A retrospective study comparing the length of admission of medium secure unit patients admitted in the three decades since 1985.

Aims and methodAdmissions of patients to secure forensic hospitals are often lengthy. Previous research has examined factors associated with prolonged admission, but studies analysing admission data at a single medium secure unit (MSU) over a prolonged time period are lacking. We compared admission data for all patients admitted to a MSU in England during the years 1985, 1995, 2005 and 2012.

Expression of class 3 semaphorins and their receptors in human breast neoplasia.

Aims: This study aimed to identify the involvement of class 3 semaphorins (Sema3) and receptors, neuropilins (Np1 and Np2) and plexins (A1-A4) in breast cancer development and angiogenesis.

Methods And Results: We quantified and correlated Sema3A, Sema3B, Sema3F and their known receptors and coreceptors Plexin-A1, Plexin-A3, Np1 and Np2 in sections of normal human breast, benign and pre-malignant hyperplastic tissue, pre-invasive and invasive cancer, and compared these findings with our previously published data on vascular endothelial growth factor (VEGF) and microvessel density (MVD) in the same samples. Histological analysis revealed that Sema3B was expressed more strongly and widely than Sema3A and 3F in normal breast tissue and all three semaphorins decreased with the transition from in situ to invasive cancer (P < 0.

Angiopoietins 1 and 2 and Tie-2 receptor expression in human ductal breast disease.

Aims:  This study aimed to identify the involvement of the angiopoietin/Tie-2 receptor system in breast cancer development, progression, metastasis and angiogenesis.

Methods And Results: We quantified and correlated angiopoietin-1 (Ang-1), Ang-2 and Tie-2 expression in sections of normal human breast, benign and premalignant hyperplastic tissue, pre-invasive and invasive cancer, and compared these findings with our previously published data on vascular endothelial growth factor (VEGF) and microvessel density (MVD) in the same samples. A breast cancer tissue microarray was used to evaluate the prognostic value of these factors.

Social matching of food intake and the need for social acceptance.

In a social eating context individuals tend to match their food intake to that of eating companions, regardless of whether the other person is eating a large amount. However, relatively little is known about the underlying processes of food intake matching. Findings from behavioural mimicry research suggest that individuals may copy how those around them act in order to facilitate social interactions and ingratiate themselves.

Pediatric brain tumor cancer stem cells: cell cycle dynamics, DNA repair, and etoposide extrusion.

Reliable model systems are needed to elucidate the role cancer stem cells (CSCs) play in pediatric brain tumor drug resistance. The majority of studies to date have focused on clinically distinct adult tumors and restricted tumor types. Here, the CSC component of 7 newly established primary pediatric cell lines (2 ependymomas, 2 medulloblastomas, 2 gliomas, and a CNS primitive neuroectodermal tumor) was thoroughly characterized.
