Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

AI snake oil? A risk/benefit analysis for toxicology
Artificial intelligence (AI) is increasingly used to support predictive, mechanistic, and human-relevant toxicology at scale. However, its integration into regulatory science - particularly in drug development - remains uneven, because encouraging ...

The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Next generation validation for next generation risk assessment
Next 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 ...

International cooperation for alternatives to animal testing
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 ...

Giving meaning to alternative methods to animal testing
The 3 rd edition of the advanced theoretical-training course “ Giving meaning to alternative methods to animal testing ” was held in Genoa on July 6-7, 2017. The theoretical modules included talks by specialists from companies engaged in the field of advanced in vitro technologies, who offered participants the possibility to try out their technologies ...

We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The (misleading) role of animal models in drug development
Animals 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 ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
