SFRS7-mediated splicing of tau exon 10 is directly regulated by STOX1A in glial cells.

<h4>Background</h4>In this study, we performed a genome-wide search for effector genes bound by STOX1A, a winged helix transcription factor recently demonstrated to be involved in late onset Alzheimer's disease and affecting the amyloid processing pathway.<h4>Methodology/princ...
