Figure Lengend Snippet: ( A ) The expression profiles of genes involved in hippocampal development in control and the double-mutant mice at E11.5. Data are presented as mean ± SEM. Student’s t test was used in A, * P< 0.05, ** P< 0.01; n represents separate experiments, n=3. ( B ) Compared with that of control mice ( a, b, a’, b’, a’’, b’’, i, j, i’, j’, q, r, q’, r’ ), the expression of Lhx5 was reduced in double-mutant mice at E11.5 ( c, d, c’, d’, c’’, d’’ ), E13.5 ( k, l, k’, l’ ), and E14.5 ( s, t, s’, t’ ); the expression of Lhx2 was comparable between the control and double-mutant mice at E11.5 ( e–h, e’–h’ ); and compared with that of control mice ( m, n, m’, n’, u, v, u’, v’ ), the expression of Lhx2 was increased in double-mutant mice at E13.5 ( o, p, o’, p’ ) and E14.5 ( w, x, w’, x’ ). ( C ) Compared with that of control mice ( a, b, a’, b’ ), the expression of Sox2 was normal in double-mutant mice at E14.5 ( c, d, c’, d’ ); compared with that of control mice ( e, f, e’, f’ ), the expression of Tbr2 was decreased in Nr2f mutant mice at E14.5 ( g, h, g’, h’ ); compared with that of control mice ( i, j, i’, j’ ), the expression of NeuroD1 was reduced in double-mutant mice at E14.5 ( k, l, k’, l’ ). ( D ) Quantitative analysis of Tbr2-positive cells and NeuroD1-positive cells in ( Ce’–h’ ) and ( Ci’–l’ ). Data are presented as mean ± SEM. Student’s t test was used in D, ** P< 0.01; n represents separate experiments, n=3. ( E ), In the hippocampal primordium of the early embryo, Nr2f1 is expressed dorsally in the MP, and Nr2f2 is expressed ventrally in the CH. In the mature hippocampus, the expression of Nr2f1 is higher in the dorsal hippocampus, which is related to spatial learning and memory, and the expression of Nr2f2 is mainly in the ventral hippocampus, which is associated with emotion and anxiety ( a ). Our findings support a novel molecular mechanism by which Nr2f1 and Nr2f2 may cooperate to ensure the appropriate morphogenesis and functions of the hippocampus by modulating the Lhx5-Lhx2 axis ( b ).
