Alternatives to the use of animals in safety testing as required by the EU-Cosmetics Directive 2009

open access: yes, 2009
Ingredients of cosmetic products are no longer allowed to be tested by animal experimentation (EU-Cosmetics Directive 76/768 EEC). For several toxicological endpoints this testing ban applies since March 11, 2009, while repeated dose toxicity tests and ...

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

When Is Something an Alternative? A General Account Applied to Animal-Free Alternatives to Animal Research

open access: yes
The first “R” from animal research ethics prescribes the replacement of animal experiments with animal-free alternatives. However, the question of when an animal-free method qualifies as an alternative to animal experiments remains unresolved.

Development and evaluation of a robust, common protocols for reconstructed human skin models: In vitro skin irritation/corrosion testing

open access: yes, 2006
Due to the increased need for information on the safety of chemicals (driven mainly by new the chemicals policy of the European Commission (REACH)) a lot of attention is paid to development and validation of in vitro methods replacing or reducing the use

Bridging the gap: a genetically validated avian chorioallantoic membrane platform for investigation of spontaneous circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Comparison of human skin irritation and photo-irritation patch test data with cellular in vitro assays and animal in vivo data

open access: yes, 2008
Replacement of the rabbit Draize skin irritation test or the animal photo-irritation test is in course in Europeunder the REACH chemical strategy and the Cosmetics Directive. Various in vitro protocols, including3D skin models, have been assessed.
