Pallial expression of Enc1 RNA in postnatal mouse telencephalon.
We analysed the pallial expression pattern of Enc1 (a member of the kelch family of genes) in postnatal mice (P1-P10). At early developmental stages this gene plays a role in the histogenesis of cortical structures [M.C. Hernández, P.J. Andrés-Barquin, S. MartÃnez, A. Bulfone, J.L.R. Rubenstein, M.A. Israel, Enc1: novel mammalian kelch-related gene specifically expressed in the nervous system encodes an actino-binding protein, J. Neurosci. 17 (1997) 3038-3051]. A restricted expression of Enc1 was found in the mouse pallium, notably within claustroamygdaloid derivatives of the lateral pallium and in some cortical layers in the lateral, dorsal and medial pallium sectors, with distinct regional differences. The strongest cortical expression was found in isocortical layer II and in the piriform cortex, anterior olfactory area and olfactory bulb mitral cells. The lowest signal occurred in the retrosplenial cortex. The subgranular layers V/VI were also positive, particularly layer V, with clearcut areal differences. The hippocampal CA3/CA4 areas and the dentate gyrus were strongly positive. The dorsolateral (core) portion of the claustrum and dorsal endopiriform nucleus were moderately positive, as were the amygdaloid lateral and basolateral nuclei.[1]References
