FoxP2 directly regulates the reelin receptor VLDLR developmentally and by singing.

Mutations of the transcription factor FOXP2 cause a severe speech and language disorder. In songbirds, FoxP2 is expressed in the medium spiny neurons (MSNs) of the avian basal ganglia song nucleus, Area X, which is crucial for song learning and adult song performance. Experimental downregulation of FoxP2 in Area X affects spine formation, prevents neuronal plasticity induced by social context and impairs song learning.

The porcine chloride channel calcium-activated family member pCLCA4a mirrors lung expression of the human hCLCA4.

Pig models of cystic fibrosis (CF) have recently been established that are expected to mimic the human disease closer than mouse models do. The human CLCA (originally named chloride channels, calcium-activated) member hCLCA4 is considered a potential modifier of disease severity in CF, but its murine ortholog, mCLCA6, is not expressed in the mouse lung. Here, we have characterized the genomic structure, protein processing, and tissue expression patterns of the porcine ortholog to hCLCA4, pCLCA4a.

Arc/Arg3.1 is essential for the consolidation of synaptic plasticity and memories.

Arc/Arg3.1 is robustly induced by plasticity-producing stimulation and specifically targeted to stimulated synaptic areas. To investigate the role of Arc/Arg3.

Collagen degradation in a murine myocarditis model: relevance of matrix metalloproteinase in association with inflammatory induction.

Objective: Myocardial collagen degradation is regulated by matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinase (TIMPs). The possible relevance of MMPs in association with the inflammatory induction was investigated in a murine coxsackievirus B3 myocarditis model.

Methods: Hearts from viral infected and sham-infected BALB/c mice were analyzed by semi-quantitative RT-PCR, picrosirius red staining, Western blot analysis, and immunohistochemistry.
