Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

open access: yesMolecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Do Applicant Reactions to Gamified Cognitive Ability Tests Differ Between High- Versus Low-Stakes Settings?

open access: yesJournal of Intelligence
Although cognitive ability tests are among the best predictors of job and training performance, their acceptance among applicants is limited. However, with the current talent shortage, applicant reactions to assessments have become increasingly important.

On the Construct Validity of the Reading Section of the University of Tehran English Proficiency Test [PDF]

open access: yesJournal of English Language Teaching and Learning, 2011
University of Tehran administers a test known as The University of Tehran English Proficiency Test (the UTEPT) to PhD candidates on a yearly basis. By definition, the test can be considered a high-stakes one. The validity of high stakes tests needs to be

RECONSIDERING THE IMPACT OF HIGH‐STAKES TESTING [PDF]

open access: yesETS Research Report Series, 2003
ABSTRACTOver the last 15 years, many states have implemented high‐stakes tests as part of an effort to strengthen accountability for schools, teachers, and students. Predictably, there has been vigorous disagreement regarding the contributions of such policies to increasing test scores and, more importantly, to improving student learning.

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

open access: yesMolecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

L2 pragmatics underrepresentation as a washback mechanism in EFL contexts: Linking test-design features to high-stakes test use [PDF]

open access: yesTeaching English Language, 2014
Considering the status of 'washback' in validity theory and research, Messick warns that, to establish test validity, one should not rely merely on washback, with all its complexity, but should instead probe test design properties (i.e., authenticity and

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

open access: yesFEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

open access: yesFEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.
