ABSTRACT Nerve growth factor (NGF) regulates the functions of neurons by binding the p75 neurotrophin receptor (p75NTR) and TrkA receptors. It is shown here that it has been found that the Sall2 transcription factor forms a complex with p75NTR. NGF dissociates Sall2 from p75NTR and also activates TrkA, which promotes translocation of Sall2 into the nucleus. Nuclear Sall2 activates target genes that modulate the growth and development of neurons. Thus, one way that p75NTR and TrkA can modulate the functions of neurons is by regulating the localization and actions of Sall2.

    ABSTRACT: SB431542 (SB) is an established small molecular inhibitor that specifically bind to the ATP binding domains of the activin receptor-like kinase receptors, ALK5, ALK4 and ALK7, and thus specifically inhibits Smad2/3 activation and block TGF-β signal transduction. SB maintains the undifferentiated state of mouse embryonic stem cells. However, the way of SB in maintaining the undifferentiated state of mouse embryonic stem cells remain unclear. Considering that SB could not maintain embryonic stem cells pluripotency when leukemia inhibitory factor was withdrawn, we sought to identify the mechanism of SB on pluripotent maintenance. Transcripts regulated by SB, including message RNAs and small non-coding RNAs were examined through microarray and deep-sequence experiments. After examination, Western blot analysis, and quantitative real-time PCR verification, we found that SB regulated the transcript expressions related to self-renewal and differentiation. SB mainly functioned by inhibiting differentiation. The key pluripotent factor expression was not significantly affected by SB, and intrinsic differentiation-related transcripts including fibroblast growth factor family members, were significantly down-regulated. Moreover, SB could partially inhibit the retinoic acid response to neuronal differentiation of mouse embryonic stem cells.

    ABSTRACT: Ocular coloboma is a congenital defect resulting from failure of normal closure of the optic fissure during embryonic eye development. This birth defect causes childhood blindness worldwide, yet the genetic aetiology is poorly understood. Here we identified a novel homozygous mutation in the SALL2 gene in members of a consanguineous family affected with non-syndromic ocular coloboma variably affecting the iris and retina. This mutation, c.85G>T, introduces a premature termination codon (p.Glu29*) predicted to truncate the SALL2 protein so that it lacks three clusters of zinc finger motifs that are essential for DNA binding activity. This discovery identifies SALL2 as the third member of the Drosophila homeotic Spalt-like family of developmental transcription factor genes implicated in human disease. SALL2 is expressed in the developing human retina at the time of, and subsequent to, optic fissure closure. Analysis of Sall2-deficient mouse embryos revealed delayed apposition of the optic fissure margins and the persistence of an anterior retinal coloboma phenotype after birth. Sall2-deficient embryos displayed correct posterior closure toward the optic nerve head, and upon contact of the fissure margins, dissolution of the basal lamina occurred and PAX2, known to be critical for this process, was expressed normally. Anterior closure was disrupted with the fissure margins failing to meet, or in some cases misaligning leading to a retinal lesion. These observations demonstrate, for the first time, a role for SALL2 in eye morphogenesis and that loss-of-function of the gene causes ocular coloboma in humans and mice.
