1. Estudo da expressão da miostatina em modelos murinos para doenças neuromusculares. / Myostatin expression in mouse models of neuromuscular diseases.
A proteína miostatina, é um regulador negativo do crescimento muscular e a modulação de sua expressão pode consistir em tratamento para distrofias musculares. Nós estudamos expressão endógena da miostatina no músculos gastrocnêmio e diafragma de 4 modelos murinos de degeneração muscular: os camundongos Dmdmdx, SJL/J, Largemyd e Lama2dy-2J/J. Obse

2. Caracterização bioquimica e farmacologica de polipeptideos do veneno da aranha Phoneutria nigriventer
This thesis describes the biochemical and pharmacological characterization of three polypeptides from the venom of the spider Phoneutria nigriventer. The fractionation of Phoneutria nigriventer venom by gel filtration on Sephadex G-10-120 provided eight peaks (SI to S-VIII) of which only the first (S-I) was investigated further. lonexchange chromatography of

3. Ca2+ and cyclic AMP regulate phosphorylation of same two membrane-associated proteins specific to nerve tissue.
It was shown previously that addition of cyclic AMP (cAMP) to a synaptic membrane fraction incubated with [gamma-32P]ATP stimulated the phosphorylation of two proteins, designated proteins Ia and Ib, found only in nerve tissue. Addition of Ca2+ plus veratridine to synaptosomes preincubated with 32Pi stimulated the phosphorylation of two proteins with similar

4. Chemotropism in nerve regeneration studied in tissue culture.
The neurotropic effect of the distal stump of transected sciatic nerve on regenerating axons emerging from the proximal stump was investigated in rats by the coculture of excised neonatal dorsal root ganglia and segments of degenerated and nondegenerated sciatic nerves. In all cultures, neurites from the ganglion extended directly towards the degenerated dis

5. Biological Activity of Nerve Growth Factor Precursor Is Dependent upon Relative Levels of Its Receptors*
Nerve growth factor (NGF) is produced as a precursor called pro-nerve growth factor (proNGF), which is secreted by many tissues and is the predominant form of NGF in the central nervous system. In Alzheimer disease brain, cholinergic neurons degenerate and can no longer transport NGF as efficiently, leading to an increase in untransported NGF in the target t

6. Induction of Periostin-like Factor and Periostin in Forearm Muscle, Tendon, and Nerve in an Animal Model of Work-related Musculoskeletal Disorder
Work-related musculoskeletal disorders (WMSDs), also known as repetitive strain injuries of the upper extremity, frequently cause disability and impairment of the upper extremities. Histopathological changes including excess collagen deposition around myofibers, cell necrosis, inflammatory cell infiltration, and increased cytokine expression result from ecce

7. Degeneration and Regeneration of Murine Skeletal Neuromuscular Junctions after Intramuscular Injection with a Sublethal Dose of Clostridium sordellii Lethal Toxin
Clostridium sordellii lethal toxin (LT), a 250-kDa protein which is the bacteria's major virulence factor, belongs to a family of large clostridial cytotoxins which glucosylate small GTP-binding proteins. Here, we report the results of our ex vivo analysis of the structure and function of skeletal neuromuscular tissue obtained from mice at various times afte

8. Vascular permeability and axonal regeneration in skin autotransplanted into the brain.
Pieces of skin were autotransplanted from the pinna of an ear into a cerebral hemisphere in 36 albino rats. The grafts were examined 2, 4 and 6 weeks later for signs of vascular permeability and for the presence of nerve fibres. An intravenously injected fluorescent protein exuded into the connective tissue of the dermis and into the spaces between epidermal

9. Merosin, a protein specific for basement membranes of Schwann cells, striated muscle, and trophoblast, is expressed late in nerve and muscle development.
We have identified a tissue-specific basement membrane-associated protein by using monoclonal antibodies prepared against a protein fraction of human placenta. In immunofluorescence, the monoclonal antibodies stained basement membranes of Schwann cells, striated muscle, and trophoblast, whereas no reaction was seen with any other basement membrane or tissue

10. Tissue damage in the amyloidoses: Transthyretin monomers and nonnative oligomers are the major cytotoxic species in tissue culture
The transthyretin (TTR) amyloidoses are human diseases in which the misfolded TTR protein aggregates in tissues with subsequent visceral, peripheral, and autonomic nerve dysfunction. Recent reports have stressed the importance of oligomeric intermediates as major cytotoxic species in various forms of amyloidogenesis. We have examined the cytotoxic effects of

11. Helix-loop-helix transcription factors E12 and E47 are not essential for skeletal or cardiac myogenesis, erythropoiesis, chondrogenesis, or neurogenesis.
E12 and E47 are two non-tissue-specific helix-loop-helix (HLH) transcription factors encoded by the E2A gene. Previous studies suggested that they are involved in regulation of differentiation in many tissue types including muscle, blood, and nerve through direct heterodimer interactions with tissue-specific HLH proteins. To gain further genetic insight into

12. Defective muscle basement membrane and lack of M-laminin in the dystrophic dy/dy mouse.
M-laminin is a major member of the laminin family of basement membrane proteins. It is prominently expressed in striated muscle and peripheral nerve. M-laminin is deficient in patients with the autosomal recessive Fukuyama congenital muscular dystrophy but is normal in patients with the sex-linked Duchenne and Becker muscular dystrophies. We have examined M-
