This study was conducted to assess the effects of Cd exposure on estrogen signaling in the zebrafish brain, and the potential protective role of Zn against Cd-induced toxicity. Effects on the transcriptional activation of estrogen receptors, aromatase B protein expression and molecular expression of related genes were examined. Our results demonstrate that Cd acts as a potent anti-estrogen in vivo and in vitro, and that Cd-induced estradiol antagonism can be reversed, at the protein level, by Zn supplement.

The Interagency Coordinating Committee for the Validation of Alternative Methods (ICCVAM) evaluated a non-animal decision strategies to predict skin sensitization. Machine learning approaches integrated in vitro, in chemico and in silico data and six physicochemical properties for 120 substances to predict murine local lymph node assay (LLNA) outcomes. The seven models with the highest accuracy used a support vector machine with different combinations of predictor variables. The models outperformed individual non-animal methods and test batteries. This suggests that computational approaches are promising tools to effectively integrate data to identify potential skin sensitizers without animal testing.
- Gelucire and Gelucire-PEG400 formulations; tolerability in species used for non-clinical safety testing after oral (gavage) dosing

Article first published online: 5 FEB 2016 | DOI: 10.1002/jat.3296
A series of oral tolerability studies were conducted with Gelucire and Gelucire:PEG400 formulations in rats, dogs and minipigs in order to determine tolerable daily dose volumes in these species. It was concluded that Gelucire:PEG400 (90:10) was tolerated in Beagle dogs when administered at 1 ml kg–1 once daily for 39 weeks, and 100% Gelucire was tolerated in the rat and the minipig when administered once daily at 5 ml kg–1 for 5 days.
- Nanosuspension formulations of poorly water-soluble compounds for intravenous administration in exploratory toxicity studies: in vitro and in vivo evaluation
Hisako Fujimura, Takao Komasaka, Taizo Tomari, Yasunori Kitano and Kouji Takekawa

Nanosuspensions for intravenous injections were prepared using a mixer mill and zirconia beads with a vehicle of 2% (w/v) poloxamer 338, which was confirmed to induce no histamine release in dogs. Sterilized nanosuspensions were obtained by milling for 30 min, followed by autoclaving for 20 min at 121 °C and milling for 30 min (mill–autoclave–mill method). The enhancing effect of a nanosuspension on exposure in dogs and the versatility of the method were demonstrated.
- Depth-dependent stratum corneum permeability in human skin in vitro

Article first published online: 3 FEB 2016 | DOI: 10.1002/jat.3289
The stratum corneum (SC) concentration–thickness profiles were determined for four model chemicals on intact and adhesive tape-stripped skin samples to clarify whether SC is a homogeneous barrier for chemical transport. Data analysis with the diffusion equation of Fick's second law permitted the chemical diffusion coefficient in SC. Results suggested the depth-dependency of SC permeability to panthenol, benzoic acid and butenafine; variation of the diffusion coefficient from the SC surface to the deeper layers agreed with a change in the diffusion coefficient over time in intact skin.
