Example hits identified from our primary screen as regulators of oligodendrocyte development.
(A-D) (upper panels) Representative brightfield images of the Tg(mbp:EGFP) screening line following treatment with control (1%DMSO) (A), our top hit compound splitomicin (B) and two HDAC inhibitors, apicidin (C) and suberohydroxamic acid (SBHA) (D), that significantly decreased oligodendrocyte number in our screen. (B) Apicidin treatment disrupted morphological development of the jaw (indicated by arrow) and heart (indicated by arrowhead). Scale bar, 400 ?m. (lower panels) Whole spinal cord images in the Tg(mbp:EGFP) line showing the effect of splitomicin, apicidin and SBHA on oligodendrocyte cell number. Mean numbers of dorsal oligodendrocytes quantified in the screen and in the example images shown are provided above each corresponding image. Scale bar, 200 ?m.
