Next generation validation for next generation risk assessment
Frontiers in ToxicologyNext generation risk assessment (NGRA) demands a fundamental transformation in how toxicological test methods are validated. Traditional validation approaches, designed for animal tests and mainly for simple in vitro methods, are increasingly inadequate ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

International cooperation for alternatives to animal testing
Folia Pharmacologica Japonica, 2011 動物実験代替法（以下，代替法と記す）の開発を促すために各国に設立された代替法バリデーションセンターの協調を図るため，2009年に日米欧カナダの参加で，代替試験法協力国際会議（ICATM: International Cooperation on Alternative Test Methods）の覚書が交わされ，代替法の開発に国際協調がより重要視されることになった．さらに，2011年には韓国の追加参入が決まり，新たな覚書が交わされた．このICATMの取り決めに準じた日本動物実験代替法評価センター（JaCVAM: Japanese Center for the Validation of Alternative Methods）の活動状況および今後の国際対応についてまとめた．本来なら ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The (misleading) role of animal models in drug development
Frontiers in Drug DiscoveryAnimals like mice and rats have long been used in medical research to help understand disease and test potential new treatments before human trials. However, while animal studies have contributed to important advances, too much reliance on animal models ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
