The temporal and spatial regulation of somitogenesis requires a molecular oscillator, the segmentation clock. Through Notch signalling, oscillation in cells is coordinated translated into cyclic wave expression hairy-related other genes. sweeps caudorostrally through presomitic mesoderm (PSM) finally arrests at future point anterior PSM. By experimental manipulation analyses zebrafish mutants, we have found novel component involved this process. We report that level Fgf/MAPK activation...

Four members of the TEAD/TEF family transcription factors are expressed widely in mouse embryos and adult tissues. Although vitro studies have suggested various roles for TEAD proteins, their vivo functions remain poorly understood. Here we examined role Tead genes by generating mutants Tead1 Tead2. Tead2(-/-) mice appeared normal, but Tead1(-/-); died at embryonic day 9.5 (E9.5) with severe growth defects morphological abnormalities. At E8.5, were already small lacked characteristic...

The telencephalon is formed in the most anterior part of central nervous system (CNS) and organised into ventral subpallial dorsal pallial domains. In mice, it has been demonstrated that Fgf signalling an important role induction patterning telencephalon. However, precise still unclear, owing to overlapping functions family genes. To address this, we have examined, zebrafish embryos, activation Ras/mitogen-activated protein kinase (MAPK), one major downstream targets signalling....

BackgroundMicroglia of the central nervous system act as sentinels and rapidly react to infection or inflammation. The pathophysiological role bone marrow-derived microglia is particular interest because they affect neurodegenerative disorders neuropathic pain. hypothesis current study that chronic psychological stress (chronic PS) induces infiltration into hypothalamus by means chemokine axes in brain marrow.

Summary Bone marrow–derived microglia aggregated in the central nucleus of amygdala are involved chronic neuropathic pain–induced anxiety. Chronic pain causes abnormal sensitivities such as hyperalgesia and allodynia, emotional abnormalities anxiety depression. Although spinal cord sensitivity to pain, no previous studies have examined mechanism Here, we involvement bone marrow (BM)–derived amygdalae mice with development anxiety-like behavior. We prepared partial sciatic nerve ligations...

Dachsous (Dchs), an atypical cadherin, is evolutionarily conserved regulator of planar cell polarity, tissue size, and adhesion. In humans, DCHS1 mutations cause pleiotropic Van Maldergem syndrome. Here, we report that in zebrafish dchs1b dchs2 disrupt several aspects embryogenesis, including gastrulation. Unexpectedly, maternal zygotic (MZ) mutants show defects the earliest developmental stage, egg activation, abnormal cortical granule exocytosis (CGE), cytoplasmic segregation, cleavages,...

Interventions that preserve motor neurons or restore functional neuroplasticity may extend longevity in amyotrophic lateral sclerosis (ALS). Delivery of neurotrophins potentially revive degenerating neurons, yet this approach is dependent on the proper subcellular localization neurotrophin receptor (NTR) to plasmalemmal signaling microdomains, termed membrane/lipid rafts (MLRs). We previously showed over-expression synapsin-driven caveolin-1 (Cav-1) (SynCav1) increases MLR NTR [e.g.,...

We addressed mechanism mouse node development via an analysis node/notochord enhancer (NE) Foxa2. first identified core element (CE) enhancer, which in multimeric form drives gene expression node. CE was activated Wnt/β-catenin-treated P19 cells with a time lag, this activation dependent on two separate sequence motifs within CE. These same were also required for transgenic embryos.

Abstract Anteroposterior (AP) axis extension during gastrulation requires embryonic patterning and morphogenesis to be spatiotemporally coordinated, but the underlying genetic mechanisms remain poorly understood. Here we define a role for conserved chromatin factor Gon4l, encoded by ugly duckling ( udu ), in coordinating tissue zebrafish through direct positive negative regulation of gene expression. Although identified as recessive enhancer impaired planar cell polarity (PCP) mutants,...

Elevating neuroprotective proteins using adeno-associated virus (AAV)-mediated gene delivery shows great promise in combating devastating neurodegenerative diseases. Amyotrophic lateral sclerosis (ALS) is one such disease resulting from loss of upper and lower motor neurons (MNs) with 90-95% cases sporadic (SALS) nature. Due to the unknown etiology SALS, interventions that afford neuronal protection preservation are urgently needed. Caveolin-1 (Cav-1), a membrane/lipid rafts (MLRs)...
