This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural microtubule-associated proteins (MAPs) are capable of interacting with tubulin dimers to regulate the various dynamic stages of microtubules. MAP1a is predominant in the neuronal cell body, axons and dendrites of mature neurons. MAP1 a has been shown to bind microtubules to promote microtubule assembly in vitro. The MAP1a heavy chain molecule is associated with three light chains. The heavy chain, and all three light chains appear to associate with microtubules independent of each other. The purpose of this project was to measure the impact of myc-tagged MAP1 a fragments and myc-tagged light chains associated with MAP1a on microtubule dynamic phases in vivo. Cells from an epithelial kidney cell line (LLCPK1) that had been permanently transfected with human GFP-alpha tubulin were transiently transfected with myc tagged MAP1a heavy and light chain fragments. Cells expressing MAP1a and light chain fragments were used to make direct observations of microtubule dynamics in living cells using fluorescence microscopy. Microtubule ends were photographed at 4-second intervals using a digital camera over a 2-minute duration. All truncated MAP1 a heavy chain fragments that contained the microtubule-binding domain were shown to associate with microtubules. MAP1a fragments containing portions of the projection domain promoted growth and stability of microtubules. Truncated fragments containing different regions of the projection domain of MAP1a demonstrated variations in their impact on microtubule dynamic events by promoting growth or inhibition of shortening phases. Similar to full length MAP1a, LC3 also appeared to promote microtubule growth and stability. Results from the present study suggest that MAP1a and LC3 promote slow, stable growth of microtubules. This type of growth may be important in the maintenance and restructuring of adult neurons.

Download or read book Modulation of Microtubule Dynamics in Netrin Signaling written by Huai Huang and published by . This book was released on 2017 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuronal development proceeds through several stages, such as axon and dendrite differentiation, elongation, branching, and pathfinding. Extracellular guidance cues play an essential role in these processes. Activation of downstream signaling of guidance receptors eventually leads to the cytoskeleton rearrangement. Microtubules (MTs), as one form of the cytoskeleton, play an important role in axon and dendrite outgrowth, elongation and branching. Netrin-1, a canonical guidance molecule, binds to its receptors Deleted in Colorectal Cancer (DCC), Down Syndrome Cell Adhesion Molecule (DSCAM) and uncoordinated-5 (UNC5) mediating neuronal development. Our recent studies have shown that TUBB3, a neuronal ß-tubulin isotype III, directly binds to DCC and Netrin-1 induces this interaction. Results from multiple function assays indicate that TUBB3 is specifically involved in Netrin-1-induced axon outgrowth and guidance. Heterozygous missense mutations in human TUBB3 gene result in a spectrum of brain malformations associated with defects in axon guidance, neuronal migration, and differentiation. However, the molecular mechanisms underlying mutation-related axon guidance abnormalities are unclear. Here, we provide evidence that TUBB3 mutations impair Netrin/DCC signaling in the developing nervous system. The interaction of DCC with most of TUBB3 mutants (eight out of twelve) is significantly reduced compared to the wild type TUBB3. TUBB3 mutants R262C and A302V exhibit decreased subcellular colocalization with DCC in the growth cones of primary neurons. Netrin-1 enhances the interaction of endogenous DCC with wild type human TUBB3, but not with R262C or A302V, in primary neurons. Netrin-1 also increases the co-sedimentation of DCC with polymerized MTs in primary neurons expressing wild type TUBB3, but not R262C or A302V. Expression of either R262C or A302V not only suppresses Netrin-1-induced neurite outgrowth, branching and attraction in vitro, but also causes defects in spinal cord commissural axon projection and pathfinding in ovo. Our study reveals that missense TUBB3 mutations specifically disrupt Netrin/DCC-mediated attractive signaling. MT dynamics play an important role in Netrin-1-promoted axon outgrowth, branching, and axon pathfinding. However, the mechanism by which Netrin-1 regulates this process is not clear. The MT-associated protein (MAP) tau regulates MT stability and dynamics, which are important for neuronal development in the nervous system. Our study shows that tau interacts with the Netrin receptor DCC, and Netrin-1 induces this interaction in primary neurons. Tau colocalizes with DCC in the growth cone of primary neurons and Netrin-1 induces this colocalization. Activation of JNK, GSK-3 and Src family kinases are important for Netrin-1-induced DCC/tau interaction. Knockdown of tau inhibits Netrin-1-induced axon outgrowth, branching and commissural axon attraction in vitro and leads to defects in commissural axon projection in the chick spinal cord in vivo. These findings suggest that tau is involved in Netrin-1 signaling and essential for Netrin-1-promoted neuronal development. In general, these studies are focusing on the role of MT component protein TUBB3 and MT-associated protein tau in the Netrin-1 signaling. The study of TUBB3 mutants further validates the essential role of TUBB3 in Netrin-1-mediated neuronal development by showing that TUBB3 mutants A302V and R262C found in patients disrupt the function of TUBB3 in Netrin-1-mediated neurite outgrowth, axon branching and attraction. The study of tau reveals that tau is involved in Netrin-1-mediated neuronal development. However, the questions regarding the relationship between TUBB3 and tau in Netrin signaling need to be further addressed. For instance, whether Netrin-1 regulates the interaction between tau and TUBB3, and whether the interaction between DCC and tau is dependent upon the presence of TUBB3 need to be clarified.

Available in PDF, EPUB and Kindle. Book excerpt: The cytoskeleton is a highly dynamic intracellular platform constituted by a three-dimensional network of proteins responsible for key cellular roles as structure and shape, cell growth and development, and offering to the cell with "motility" that being the ability of the entire cell to move and for material to be moved within the cell in a regulated fashion (vesicle trafficking). The present edition of Cytoskeleton provides new insights into the structure-functional features, dynamics, and cytoskeleton's relationship to diseases. The authors' contribution in this book will be of substantial importance to a wide audience such as clinicians, researches, educators, and students interested in getting updated knowledge about molecular basis of cytoskeleton, such as regulation of cell vital processes by actin-binding proteins as cell morphogenesis, motility, their implications in cell signaling, as well as strategies for clinical trial and alternative therapies based in multitargeting molecules to tackle diseases, that is, cancer.

Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.
