Abstract

A modified polyacrylamide gel electrophoresis system is described which provides excellent resolution of very high molecular weight proteins. This system has been successfully applied to the immunochemical detection of dystrophin in mouse and rat skeletal muscle, mouse myotubes in cell culture, and in human muscle-biopsy specimens. The mass of total homogenate protein (3–12 μg) and the relative quantity of dystrophin detected immunologically were found to be strongly correlated (r = 0.970 – 0.995). The method described here requires minute quantities of tissue or cells to accurately evaluate the relative amount of dystrophin present. The entire procedure for the detection of dystrophin is simple, rapid and cost efficient compared to other available techniques.

Telethonin protein expression in neuromuscular disorders
2002, Biochimica et Biophysica Acta - Molecular Basis of Disease
Telethonin is a 19-kDa sarcomeric protein, localized to the Z-disc of skeletal and cardiac muscles. Mutations in the telethonin gene cause limb–girdle muscular dystrophy type 2G (LGMD2G).
We investigated the sarcomeric integrity of muscle fibers in LGMD2G patients, through double immunofluorescence analysis for telethonin with three sarcomeric proteins: titin, α-actinin-2, and myotilin and observed the typical cross striation pattern, suggesting that the Z-line of the sarcomere is apparently preserved, despite the absence of telethonin. Ultrastructural analysis confirmed the integrity of the sarcomeric architecture. The possible interaction of telethonin with other proteins responsible for several forms of neuromuscular disorders was also analyzed. Telethonin was clearly present in the rods in nemaline myopathy (NM) muscle fibers, confirming its localization to the Z-line of the sarcomere. Muscle from patients with absent telethonin showed normal expression for the proteins dystrophin, sarcoglycans, dysferlin, and calpain-3. Additionally, telethonin showed normal localization in muscle biopsies from patients with LGMD2A, LGMD2B, sarcoglycanopathies, and Duchenne muscular dystrophy (DMD). Therefore, the primary deficiency of calpain-3, dysferlin, sarcoglycans, and dystrophin do not seem to alter telethonin expression.
Nebulin expression in patients with nemaline myopathy
2001, Neuromuscular Disorders
Nemaline myopathy is a structural congenital myopathy which may show both autosomal dominant and autosomal recessive inheritance patterns. Mutations in three different genes have been identified as the cause of nemaline myopathy: the gene for slow α-tropomyosin 3 (TPM3) at 1q22–23, the nebulin gene (NEB) at 2q21.1–q22, and the actin gene (ACTA1) at 1q42. The typical autosomal recessive form appears to be the most common one and is caused by mutations in the nebulin gene. We have studied the pattern of nebulin labeling, in patients with the typical congenital form (ten patients), the severe congenital form (two patients) or the mild, childhood-onset form (one patient), using antibodies against three different domains of nebulin. A qualitative and quantitative nebulin analysis in muscle tissue showed the presence of nebulin in myofibers from all patients. Some differences relating to the rod structure were observed. The majority of the largest subsarcolemmal rods were not labeled with the N2 nebulin antibody (I-band epitope) and showed an indistinct pattern with the two antibodies directed to the Z-band portion of nebulin (epitopes M176–181 and serine-rich domain). Diffuse rods were not revealed using the three antibodies. A discordant pattern of nebulin N2 epitope labeling was found in two affected sisters with a mutation in the nebulin gene, suggesting that modifications in nebulin distribution inside the rods might occur with the progression of the disease. Western blot analysis showed no direct correlation with immunofluorescence data. In nine patients, the band had a molecular weight comparable to the normal control, while in one patient, it was detected with a higher molecular weight. Our results suggest that presence/absence of specific nebulin Z-band epitopes in rod structures is variable and could depend on the degree of rod organization.
Sarcoglycanopathies are responsible for 68% of severe autosomal recessive limb-girdle muscular dystrophy in the Brazilian population
1999, Journal of the Neurological Sciences
Sarcoglycanopathies (SGPs) constitute a subgroup of limb-girdle muscular dystrophies (LGMD), where the primary defect in one sarcoglycan (SG) glycoprotein (α-SG, β-SG, γ-SG or δ-SG) results in a deficiency of the whole complex. Four genes, at 17q, 4q, 13q and 5q, encode the four glycoproteins, and mutations in these genes cause diseases called LGMD2D, 2E, 2C and 2F. To estimate the prevalence, relative proportions and clinical features of SGPs, we have studied the SG proteins in muscle biopsies of 140 patients (from 115 unrelated Brazilian families) with a clinical diagnosis of LGMD. α-SG immunofluorescence analysis showed a positive staining pattern in 70% (80/115) of the families, a patchy pattern in 14% (16/115) and a negative pattern in 16% (19/115) of the families. All the 19 α-SG negative, and four of the 16 α-SG patchy patients were also deficient for the other three SG proteins, confirming the diagnosis of SGP in 20% of the LGMD families. None of the positive α-SG patients were deficient for any of the other three SG proteins, supporting the view that the SG complex functions as a unit. DNA analysis for the four sarcoglycan genes showed that α-SG mutations accounted for 47%, β-SG for 16%, γ-SG for 16% and δ-SG for 21% of the cases. SG abnormalities were observed in only 8.5% of patients with milder LGMD forms, but were present in 68% of patients with a severe Duchenne-like course. The relatively high frequency of SGP among Brazilian people with LGMD may be due to the disproportionally high frequency of African Brazilian SGP patients with the same mutation (particularly among LGMD2C and 2F patients), suggesting a founder effect. Consanguinity is also common in our SGP families.
Double trouble: Combined myophosphorylase and AMP deaminase deficiency in a child homozygous for nonsense mutations at both loci
1995, Neuromuscular Disorders
A 2-yr-old boy had congenital hypotonia, limb weakness, exercise intolerance and one episode of myoglobinuria. Histochemical and biochemical analysis of muscle showed a combined defect of phosphorylase and AMP deaminase. DNA analysis showed that the child was homozygous for the mutations commonly found in both McArdle's disease and AMP deaminase deficiency. The father was heterozygous for both mutations. The mother was heterozygous for the myophosphorylase gene mutation and homozygous for the mutation in the AMP deaminase 1 gene.
Is dystrophin always altered in Becker muscular dystrophy patients?
1995, Journal of the Neurological Sciences
The differential diagnosis between autosomal recessive limb-girdle (LGMD) and X-linked Becker muscular dystrophy (BMD) is very important for genetic counseling. It has been hypothesized that all BMD patients would have dystrophin alterations and dystrophin analysis could identify the Xp21 MD. Qualitatively abnormal dystrophin is easily detectable, but it is generally associated with in-frame DNA deletions or duplications. In patients with no detectable DNA deletions, in which X-linked inheritance cannot be proved, dystrophin quantification is still the only available test for differential diagnosis. In order to assess the accuracy of dystrophin quantification test in delineating Becker patients, we analyzed dystrophin abundance in BMD patients with a positive history of X-linked inheritance and no DNA detectable mutation, as compared to patients from families with LGMD. We observed that patients from 2 among the 5 BMD families have nearly normal dystrophin, while alteration in dystrophin content was observed in patients from 2 among the 7 LGMD families studied (probably as a secondary effect of alteration in the whole dystrophin-glycoproteins complex). These results suggest that dystrophin quantification, as an isolated test is not helpful for differential diagnosis between BMD and LGMD.
Spinach carbonic anhydrase: Identification of two immunologically related protein species
1994, Phytochemistry
When submitted to several chromatographic steps, carbonic anhydrase (CA: carbonate dehydratase; EC 4.2.1.1) of spinach leaves appeared as two closely spaced but distinct bands at M_r ≈ 28 × 10³ as indicated by analytical SDS-polyacrylamide gel electrophoresis. Immunochemical analyses demonstrated that both peptides reacted equally with a spinach carbonic anhydrase specific antibody. Two dimensional gel immunoelectrophoretic analysis of CA indicates the presence of charge variants which may arise as a result of chemical modification. Column chromatofocusing also revealed that spinach carbonic anhydrase possesses a pI of ≈ 5.3, which is similar to animal isoforms.
