In order to study the mechanism of neural patterning in Xenopus, we used subtractive cloning to isolate genes activated early during this process. One gene isolated was opl, (odd-paired-like) that resembles the Drosophila pair-rule gene odd-paired and encodes a zinc finger protein that is a member of the Zic gene family. At the onset of gastrulation, opl is expressed throughout the presumptive neural plate, indicating that neural determination has begun at this stage while, by neurula, opl expression is restricted to the dorsal neural tube and neural crest. opl encodes a transcriptional activator, with a carboxy terminal regulatory domain, which when removed increases opl activity. opl both sensitizes animal cap ectoderm to the neural inducer noggin and alters the spectrum of genes induced by noggin, allowing activation of the midbrain marker engrailed. Consistent with the later dorsal neural expression of opl, the activated form of opl is able to induce neural crest and dorsal neural tube ...

We have isolated a novel Xenopus homolog of the Drosophila achaete-scute genes, called XASH-3. XASH-3 expression is neural specific and is detected as early as stage 11 1/2, making it one of the earliest markers of neural induction so far described. Moreover, XASH-3 expression within the neural plate is regionally restricted. Transverse bands of XASH-3 mRNA mark discrete positions along the anteroposterior axis, while longitudinal bands mark a discrete position along the mediolateral axis. This latter site of XASH-3 expression appears to demarcate the prospective sulcus limitans, a boundary zone that later separates the functionally distinct dorsal (alar) and ventral (basal) regions of the spinal cord. In sandwich explants lacking any underlying mesoderm, XASH-3 is expressed in longitudinal stripes located lateral to the midline. This provides the first indication that planar or midline-derived inductive signals are sufficient to establish at least some aspects of positional identity along the ...

TY - JOUR. T1 - A conserved role but different partners for the transcriptional corepressor CoREST in fly and mammalian nervous system formation. AU - Dallman, Julia E.. AU - Allopenna, Janet. AU - Bassett, Andrew. AU - Travers, Andrew. AU - Mandell, Gail. PY - 2004/8/11. Y1 - 2004/8/11. N2 - Identification of conserved proteins that act to establish the neuronal phenotype has relied predominantly on structural homologies of the underlying genes. In the case of the repressor element 1 silencing transcription factor (REST), a central player in blocking the neuronal phenotype in vertebrate non-neural tissue, the invertebrate homolog is absent, raising the possibility that distinct strategies are used to establish the CNS of invertebrates. Using a yeast two-hybrid screen designed specifically to identify functional analogs of REST, we show that Drosophila melanogaster uses a strategy that is functionally similar to, but appears to have evolved independently of, REST. The gene at the center of the ...
Extracellular matrix (ECM) molecules are involved in multiple aspects of cell-to-cell signaling during development and in the adult. In nervous system development, specific recognition processes, e.g., during axonal pathfinding and synaptogenesis involve modulation and signaling by ECM components. Much less is known about their presence and possible roles in the adult nervous system. We now report that thrombospondin-4 (TSP-4), a recently discovered member of the TSP gene family is expressed by neurons, promotes neurite outgrowth, and accumulates at the neuromuscular junction and at certain synapse-rich structures in the adult. To search for muscle genes that may be involved in neuromuscular signaling, we isolated cDNAs induced in adult skeletal muscle by denervation. One of these cDNAs coded for the rat homologue of TSP-4. In skeletal muscle, it was expressed by muscle interstitial cells. The transcript was further detected in heart and in the developing and adult nervous system, where it was ...

Following the first 3 weeks of human development embryonic systems begin to be established. Over the next 5 weeks these embryonic systems lay down a template for the majority of body structures. As much as possible the known human data is shown on the individual systems notes, though there is also reference to animal models of development. See also the notes on Fetal Development. Embryonic Development section of notes covers development before later system formation.

It seems our nervous system doesnt differentiate between a physical threat and an emotional one. Thus, crying children, a critical boss, unpaid bills, traffic jams, missed deadlines and a host of other mental/emotional crises can be perceived by our nervous system as a form of danger, and may even evoke our fight-or-flight response. This defense mechanism can actually damage our health if it is evoked constantly and unnecessarily and the energy released by it is not dispelled through fighting or fleeing ...
