Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Risk assessment in animal welfare [PDF]

, 2008
Animal Welfare (AW) issues are becoming an increasing concern for food-producing and laboratory animals. Risk Assessment (RA) is usually used to describe and quantify the risk of introduction of infections, toxiinfections or residues coming from ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

The Phenion (R) Full-Thickness Skin Model for Percutaneous Absorption Testing [PDF]

, 2010
In recent years many efforts have been made to replace dermal toxicity testing of chemicals in the animal by in vitro assays. As a member of a German research consortium, we have previously contributed to the validation of an in vitro test protocol for ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

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

, 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

Animais em aulas práticas: podemos substituí-los com a mesma qualidade de ensino?

Revista Brasileira de Educação Médica
Com o objetivo de verificar a possibilidade de substituição de animais em aulas práticas, comparou-se o grau de aprendizagem entre duas turmas do curso de Medicina submetidas a aulas distintas, com e sem o uso de animais.

Toxicity testing: the search for an in vitro alternative to animal testing

British Journal of Biomedical Science, 2009
Prior to introduction to the clinic, pharmaceuticals must undergo rigorous toxicity testing to ensure their safety. Traditionally, this has been achieved using in vivo animal models. However, besides ethical reasons, there is a continual drive to reduce the number of animals used for this purpose due to concerns such as the lack of concordance seen ...
