Abstract
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive loss of motor neurons and subsequent muscular atrophy. The quality of life of patients with ALS is significantly improved by ameliorating muscular symptoms. We previously reported that glycoprotein nonmetastatic melanoma protein B (GPNMB; osteoactivin) might serve as a target for ALS therapy. In the present study, superoxide dismutase 1/glycine residue 93 changed to alanine (SOD1(G93A) ) transgenic mice were used as a model of ALS. Expression of the C-terminal fragment of GPNMB was increased in the skeletal muscles of SOD1(G93A) mice and patients with sporadic ALS. SOD1(G93A) /GPNMB transgenic mice were generated to determine whether GPNMB expression ameliorates muscular symptoms. The weight and cross-sectional area of the gastrocnemius muscle, number and cross-sectional area of myofibers, and denervation of neuromuscular junctions were ameliorated in SOD1(G93A) /GPNMB vs. SOD1(G93A) mice. Furthermore, direct injection of a GPNMB expression plasmid into the gastrocnemius muscle of SOD1(G93A) mice increased the numbers of myofibers and prevented myofiber atrophy. These findings suggest that GPNMB directly affects skeletal muscle and prevents muscular pathology in SOD1(G93A) mice and may therefore serve as a target for therapy of ALS.

Abstract
Direct routes of gene administration (intrathecal, intracerebroventricular or intraparenchymal infusion) have been used for effective and sustained gene delivery, but serious concerns exist about possible traumatic injury as well as neural damage that may lead to further tissue necrosis, apoptosis and cell death. We evaluated targeted retrograde gene delivery through the sternomastoid muscle (innervated by the spinal accessory nerves) into the injured cervical spinal cord using a recombinant adenovirus vector. LacZ gene expression in the cervical spinal cord was noted from 3 days to 4 weeks after the injection of vector into the sternomastoid muscles of the rats. Recombinant adenovirus vector was transferred via a retrograde mechanism into the injured cervical spinal cord with high transduction efficacy (80.6--98.9%) over certain adenoviral titer and dosage. Transduction was less efficient when the vector was injected 1 and 2 weeks after spinal cord injury (44.2--56.8%). Our results indicate retrograde delivery of recombinant adenovirus vector is possible immediately after spinal cord injury, and that this method is promising for gene delivery because it is effective, selective, less invasive to the injured spinal cord, has long-lasting gene expression, and is potentially feasible treatment choice for spinal cord injury.

Abstract
The ubiquitin-proteasome system (UPS) is a central component in the cellular defence against potentially toxic protein aggregates. UPS dysfunction is linked to the pathogenesis of both sporadic and inherited neurodegenerative diseases, including dominantly inherited familial amyotrophic lateral sclerosis (fALS). To investigate the role of the UPS in fALS pathogenesis, transgenic mice expressing mutant G9 3A Cu,Zn superoxide dismutase (SOD1) were crossed with transgenic mice expressing epitope tagged, wild-type or dominant-negative mutant ubiquitin (Ub(K48R)). RNase protection assays were used to confirm expression of the Ub transgenes in spinal cord and ubiquitin transgene levels were estimated to account for 9-12% of total ubiquitin. Mice expressing the G9 3A transgene exhibited neurological symptoms and histopathological changes typical of this model irrespective of ubiquitin transgene status. Impaired rotarod performance was observed in all G9 3A transgenics by 7 weeks of age irrespective of ubiquitin genotype. The presence of wild-type or mutant ubiquitin transgenes resulted in a small but significant delay in the onset of clinical symptoms and mild acceleration of disease progression, without influencing overall survival. These data suggest that relatively small changes in ubiquitin expression can influence the development of neurodegenerative disease and are consistent with a neuroprotective role for the UPS.

Abstract
During infection, adenovirus (Ad) capsids undergo microtubule-dependent retrograde transport as part of a program of vectorial transport of the viral genome to the nucleus. The microtubule-associated molecular motor, cytoplasmic dynein, has been implicated in the retrograde movement of Ad. We hypothesized that cytoplasmic dynein constituted the primary mode of association of Ad with microtubules. To evaluate this hypothesis, an Ad-microtubule binding assay was established in which microtubules were polymerized with taxol, combined with Ad in the presence or absence of microtubule-associated proteins (MAPs), and centrifuged through a glycerol cushion. The addition of purified bovine brain MAPs increased the fraction of Ad in the microtubule pellet from 17.3% +/- 3.5% to 80.7% +/- 3.8% (P < 0.01). In the absence of tubulin polymerization or in the presence of high salt, no Ad was found in the pellet. Ad binding to microtubules was not enhanced by bovine brain MAPs enriched for tau protein or by the addition of bovine serum albumin. Enhanced Ad-microtubule binding was also observed by using a fraction of MAPs purified from lung A549 epithelial cell lysate which contained cytoplasmic dynein. Ad-microtubule interaction was sensitive to the addition of ATP, a hallmark of cytoplasmic dynein-dependent microtubule interactions. Immunodepletion of cytoplasmic dynein from the A549 cell lysate abolished the MAP-enhanced Ad-microtubule binding. The interaction of Ad with both dynein and dynactin complexes was demonstrated by coimmunoprecipitation. Partially uncoated capsids isolated from cells 40 min after infection also exhibited microtubule binding. In summary, the primary mode of Ad attachment to microtubules occurs though cytoplasmic dynein-mediated binding.

Abstract
OBJECTIVE The mechanism of remote viral gene delivery to the spinal cord is unknown. The present experiment demonstrates that intraneural injection of colchicine is capable of inhibiting remote delivery of both adenoviral and adeno-associated viral (AAV) vectors, implicating axonal transport in this process. METHODS The right sciatic nerves of adult Sprague-Dawley rats were injected with phosphate-buffered saline (PBS) (n = 5) or 10 (n = 7) or 100 (n = 4) microg colchicine. Two days later, the nerves of all animals were initially injected with 1.2 x 10(7) plaque-forming units of Ad5RSVntLac-Z. Two separate groups were injected concurrently with vector and PBS (n = 5) or 10 microg colchicine (n = 5). In a second experiment, the right sciatic nerves of CD1 mice were preinjected with PBS (n = 6) or 10 microg colchicine (n = 5). Two days later, the nerves were injected with rAAVCAG-EGFPwpre (an adeno-associated vector carrying the green fluorescent protein gene). In both experiments, sciatic nerves and spinal cords were removed and analyzed for gene expression. RESULTS Sciatic nerve vector injection resulted in expression in both the nerve injection site and neuronal cell bodies located predominantly in the ipsilateral ventral horn. Analysis of variance revealed a significant treatment effect for 10 and 100 microg intraneural colchicine with inhibition of remote adenoviral delivery at 10 microg and blockade of remote delivery at 100 microg (P < 0.001). Colchicine injection concurrent with and before vector injection had similar inhibitory effects. Two-way analysis of variance revealed significant colchicine inhibition of remote delivery in both adenovirus- and AAV-injected animals (P < 0.003) but no dose-by-vector interaction, suggesting that both vectors are equally inhibited by colchicine. CONCLUSION Colchicine inhibits remote spinal cord delivery of adeno-associated and adenoviral vectors in a dose-dependent manner, suggesting that remote delivery is dependent on retrograde axonal transport.

Abstract
A murine model of motoneuron disease, the wobbler mouse, is characterized by a selective loss of cervical spinal cord motoneurons. To determine the number of motoneurons that degenerate in mice with ongoing disease, we have developed two rapid and reproducible methods for labelling specific pools of cervical motoneurons using the retrograde tracer fluorogold. The motoneurons can be labelled either by capsule application of the tracer onto the sectioned musculo-cutaneous, median and ulnar nerves or by intramuscular (i.m.) injection of the tracer into the biceps brachii muscle and flexor muscles of the forelimb. In wild-type animals, the largest number of retrogradely labelled motoneurons was found 4 days following capsule application ( approximately equal 1900 motoneurons labelled) and 6 days after i.m. injection ( approximately equal1500 motoneurons labelled). Application of these techniques in 5 week-old wobbler mice showed a 36% loss of motoneurons 4 days following tracer application to the cut nerves and a 16% loss 6 days after i.m. injections as compared to values obtained in age-matched wild-type animals in the same conditions. Our results indicate that these procedures can be applied to any rodent model to analyse quantitatively the loss of specific subpopulations of cervical motoneurons and are valuable tools for evaluating novel therapeutics.

Abstract
A replication-defective recombinant adenoviral vector containing E. coli lacZ gene was injected into the gastrocnemius muscles of transgenic mice carrying mutant Cu/Zn superoxide dismutase (SOD1) gene and non-transgenic wild-type mice at 40 weeks of age. After 60 and 90 h of the injection, lacZ staining was observed at the distal ends of the sciatic nerves in both mice groups, with the number and the distances greatly reduced in the transgenic mice. Mean velocities of retrograde transport for lacZ was estimated to be 2.1 and 0.05 mm/24 h in non-transgenic and transgenic mice, respectively. These results indicate that the retrograde axonal transport of foreign gene product is impaired in the mice model for familial amyotrophic lateral sclerosis.

Abstract
We investigated genes expression by retrograde axonal transport of replication-defective adenoviruses carrying genes for LacZ (AdLacZ) and Bcl-2 in motor neurons of transgenic mice expressing mutant human Cu/Zn superoxide dismutase (SOD1) gene containing a substitution of alanine for glycine at position 93. We found that intramuscular injection of AdLacZ into the tongue of mutant SOD1 transgenic mice and their wild-type littermates at various ages results in high expression of the transgene and similar time course of expression in hypoglossal cranial nerve nuclei, suggesting no difference in the behavior of the transgene expression between the two groups. Subsequently, we employed a molecular switching cassette for Bcl-2 designed to express Bcl-2 by Cre-loxP recombination using adenoviral vectors, and examined the COS7 and primary neuronal cells with the mutant SOD1 gene. The overexpression of Bcl-2 in both cells and the neuronal protection against staurosporine-induced apoptosis were observed, after dual infection of adenoviral vectors with cassette for Bcl-2 (AxCALNLBcl-2) and Cre recombinase (AxCANCre). After inoculation of AxCALNLBcl-2 followed by AxCANCre into the tongue of both mutant SOD1 transgenic mice and wild-type littermates, Bcl-2 was detected in both the injection site and the hypoglossal nuclei of brainstems, suggesting that this was the result of retrograde transport of AxCALNLBcl-2 and AxCANCre and expression of Bcl-2 by Cre recombinase in the hypoglossal nuclei. This strategy for delivery of exogenous genes such as Bcl-2 will be useful for studying neuronal death/survival and introducing foreign genes into postmitotic motor neurons, and in gene therapy for motor neuron diseases such as ALS.
