    • Disclosed herein is a substantially pure nucleic acid sequence encoding a mammalian 35 kDa non-dystrophin component (&dgr;-sarcoglycan) of the dystrophin-glycoprotein complex. Also disclosed are the amino acid sequence and an immunogenic peptide of &dgr;-sarcoglycan. The peptide when used to immunize a mammal, stimulates the production of antibodies which bind specifically to the &dgr;-sarcoglycan. Methods to identify mutations in the &dgr;-sarcoglycan gene associated with autosomal recessive limb-girdle muscular dystrophy are also disclosed. The identification of such mutations enables the design of nucleic acid probes which hybridize specifically to a mutant form of &dgr;-sarcoglycan, or the complement thereof, but not to the DNA of the wild-type form of the gene (or the complement thereof), under stringent hybridization conditions. Such probes are useful, for example, in connection with the diagnosis of autosomal recessive limb-girdle muscular dystrophy. In addition, the identification of such mutations enables the diagnosis of autosomal recessive limb-girdle muscular dystrophy through the use of direct DNA sequencing techniques.
    • 本文公开了编码肌营养不良蛋白 - 糖蛋白复合物的哺乳动物35kDa非肌营养不良蛋白成分(δ-莽草酸)的基本上纯的核酸序列。 还公开了δ-色氨酸的氨基酸序列和免疫原性肽。 当肽用于免疫哺乳动物时,刺激产生与δ-糖聚糖特异性结合的抗体。 还公开了鉴定与常染色体隐性遗传性肢体肌营养不良症相关的δ-色氨酸聚糖基因突变的方法。 这种突变的鉴定使得能够设计特异性地与δ-色氨酸聚糖或其互补体的突变形式杂交的核酸探针,而不与野生型形式的基因(或其互补物)的DNA杂交, 在严格的杂交条件下。 这样的探针可用于例如与常染色体隐性性腰带肌营养不良症的诊断有关。 此外,通过使用直接DNA测序技术,鉴定这种突变能够诊断常染色体隐性的腰带肌营养不良症。

    • Disclosed is a method for treating a patient suffering from the disease sarcoglycan-deficient limb-girdle muscular dystrophy by gene replacement therapy. Sarcoglycan gene replacement therapy produces extensive long-term expression of the sarcoglycan species which restores the entire sarcoglycan complex, results in the stable association of alph&agr;-dystroglycan with the sarcolemma, and eliminates the morphological markers of limb-girdle muscular dystrophy. In another aspect, the invention relates to a method for determining a specific defective sarcoglycan species in the tissue of a patient. The method involves culture of muscle cells obtained from the patient, and the independent introduction of expression vectors encoding each of the sarcoglycan species, &agr;, &bgr;, &ggr;, and &dgr;, into the cultured cells with subsequent assaying for restoration of the dystrophin-glycoprotein complex. In another aspect, the invention relates to a mouse, and cells derived therefrom, homozygous for a disrupted &agr;-sarcoglycan gene. The disruption prevents the synthesis of functional &agr;-sarcoglycan in cells of the mouse and results in the mutant mouse having no detectable sarcospan, &bgr;-, &ggr;-, &dgr;-sarcoglycan, and reduced &agr;-dystroglycan in the sarcolemma of skeletal and cardiac muscles, and a reduction of dystrophin in skeletal muscle, when compared to tissue of a mouse lacking a disrupted &agr;-sarcoglycan gene. In another aspect, the invention relates to methods for screening for therapeutic agents useful in the treatment of sarcoglycan-deficient limb-girdle muscular dystrophy. The methods involve administering a candidate therapeutic agent to a mouse, or cells derived therefrom, and assaying for therapeutic effects on the mouse or cells, with the determination of therapeutic effects being a reduction or reversal in disease progression, or a restoration of the dystroglycan complex.
    • 本发明公开了一种通过基因替代疗法治疗患有疾病肌糖肌苷缺乏症的肢体肌营养不良症的患者的方法。 Sarcoglycan基因替代疗法产生广泛的长期表达的sarcoglycan物种,其恢复整个slegoglycan复合物,导致αphorpha-dystroglycan与肌膜的稳定关联,并消除肢体肌营养不良的形态学标志物。 另一方面,本发明涉及一种用于确定患者组织中的特定缺陷型糖团聚物物种的方法。 该方法包括从患者获得的肌肉细胞的培养,以及将编码每种肌糖原聚糖物质,α,β,γ和δ的表达载体独立引入培养的细胞中,随后测定肌营养不良蛋白 - 糖蛋白复合物的恢复 。 另一方面,本发明涉及一种小鼠及其衍生的细胞,用于破坏的α-丝裂霉素基因是纯合的。 该破坏阻止了小鼠细胞中功能性α-sarcoglycan的合成,并导致突变小鼠在骨骼肌和心脏肌肉的肌膜中不具有可检测的sarcospan,β - ,γ-,δ-色氨酸聚糖和还原的α-二糖聚糖, 和与缺乏α-sarcoglycan基因的小鼠的组织相比,骨骼肌中营养不良蛋白的减少。 另一方面,本发明涉及筛选用于治疗肌糖原缺乏型肢体肌营养不良症的治疗剂的方法。 所述方法包括将候选治疗剂施用于小鼠或由其衍生的细胞,以及测定对小鼠或细胞的治疗效果,其中治疗效果的确定是疾病进展中的减少或逆转,或者肌萎缩糖复合物的恢复 。
