Development of Erf-Mediated Craniosynostosis and Pharmacological Amelioration.

ETS2 repressor factor () insufficiency causes craniosynostosis (CRS4) in humans and mice. ERF is an ETS domain transcriptional repressor regulated by Erk1/2 phosphorylation via nucleo-cytoplasmic shuttling. Here, we analyze the onset and development of the craniosynostosis phenotype in an Erf-insufficient mouse model and evaluate the potential of the residual Erf activity augmented by pharmacological compounds to ameliorate the disease.

Insulin polymorphism induced by two polyphenols: new crystal forms and advances in macromolecular powder diffraction.

This study focuses on the polymorphism of human insulin (HI) upon the binding of the phenolic derivatives p-coumaric acid or trans-resveratrol over a wide pH range. The determination of the structural behaviour of HI via X-ray powder diffraction (XRPD) and single-crystal X-ray diffraction (SCXRD) is reported. Four distinct polymorphs were identified, two of which have not been reported previously.
