Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

open access: yesMolecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

INTRALABORATORY VALIDATION OF AN ANALYTICAL METHODOLOGY BY UV/VIS SPECTROMETRY IN ORDER TO EVALUATE THE OCULAR IRRITANT POTENTIAL OF TENSOACTIVES IN RED BLOOD CELLS

open access: yesVitae, 2011
Red blood cell assay (RBC) intralaboratory validation was presented, specifically for linearity, repeatability and intermediate precision. RBC is an in vitro methodology employed for ocular irritation evaluation measuring surfactants adverse effects on ...

Towards Non-Animal Testing in European Regulatory Toxicology: An Introduction to the REACH Framework and Challenges in Implementing the 3Rs

open access: yesEuropean Journal of Risk Regulation
The European Union’s REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) Regulation aims to ensure high levels of human health and environmental protection, while also promoting alternatives to animal testing.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Effect of chemotherapy on passenger mutations in metastatic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Changes in passenger mutation load and predicted immunotherapy response after chemotherapy treatment. Tumor cells rich with passenger mutations have increased sensitivity to chemotherapy. Correlation of passenger mutations with neoantigen load suggests highly mutated clones promote a more effective response to immunotherapy, and therefore, first‐line ...

Eliminate the In Vivo Digestibility Requirement for Protein Content Claims in North America to Align Consumer Purchasing Behavior with Dietary Guidelines

open access: yesCurrent Developments in Nutrition
A roundtable discussion, held on 10 December, 2024, addressed requirements for protein quality assessment in United States and Canadian food labeling regulations, focusing on concerns with the protein digestibility-corrected amino acid score (PDCAAS ...
