Abstract

A simple method, easy to perform during an endoscopic procedure, fast and inexpensive, that allows detecting deficiencies in lactase, sucrase or maltase activities is presented. Briefly, method consists in placing a duodenal biopsy sample in an adequate vial containing lactose, sucrose or maltose solution during a few minutes, and then, adding a few drops of a glucose reactive from commercial origin. Presence of any enzymatic activity is demonstrated when released glucose from any of the disaccharides chosen reacts with the second reactive, turning solution to a red colour. Its utility is discussed and compared with other diagnostic methods.

High-throughput assays for DNA gyrase and other topoisomerases.

We have developed high-throughput microtitre plate-based assays for DNA gyrase and other DNA topoisomerases. These assays exploit the fact that negatively supercoiled plasmids form intermolecular triplexes more efficiently than when they are relaxed. Two assays are presented, one using capture of a plasmid containing a single triplex-forming sequence by an oligonucleotide tethered to the surface of a microtitre plate and subsequent detection by staining with a DNA-specific fluorescent dye. The other uses capture of a plasmid containing two triplex-forming sequences by an oligonucleotide tethered to the surface of a microtitre plate and subsequent detection by a second oligonucleotide that is radiolabelled. The assays are shown to be appropriate for assaying DNA supercoiling by Escherichia coli DNA gyrase and DNA relaxation by eukaryotic topoisomerases I and II, and E.coli topoisomerase IV. The assays are readily adaptable to other enzymes that change DNA supercoiling (e.g. restriction enzymes) and are suitable for use in a high-throughput format.

Prenatal diagnosis for severe methylenetetrahydrofolate reductase deficiency by linkage analysis and enzymatic assay.

Severe methylenetetrahydrofolate reductase (MTHFR) deficiency is characterized by varying degrees of developmental delay, motor and gait abnormalities, seizures, and thrombosis. Biochemical abnormalities include homocystinuria and hyperhomocysteinemia. Clinical severity correlates with MTHFR activity in cultured fibroblasts; activity can also be assayed in cultured amniocytes and chorionic villus cells (CVC). Forty-four private mutations have been identified, limiting the use of direct mutation detection for prenatal diagnosis. However, intragenic polymorphisms have been identified, making prenatal diagnosis by linkage analysis a possible option, even without knowledge of deleterious mutations. Prenatal diagnosis for severe MTHFR deficiency has been available by biochemical methodologies, but molecular genetic approaches have not yet been reported. We performed prenatal diagnosis for severe MTHFR deficiency in 11 at-risk pregnancies in seven families. A combined approach of linkage analysis and enzymatic assays was used in six pregnancies; linkage analysis alone was performed in one pregnancy. Linkage analysis for the 677C > T or 1298A > C polymorphisms predicted that all seven fetuses were unaffected. For six of these seven fetuses, enzymatic activities were also measured and demonstrated concordant results. Of the 10 pregnancies in which enzymatic assays were performed, activities in cultured amniocytes predicted six unaffected fetuses (1.4-7.1 nmol CHO/mg prot/h (U)) and one affected fetus (0.24 U [control 3.1-9.6 U]). Three pregnancies assessed via CVCs demonstrated two unaffected fetuses (3.6 and 7.7 U) and 1 affected fetus (0 U [control 4.5-7.8 U]). These values were compared to those of the probands (range = 0.02-0.7 U (control 2.4-11.7 U)) in cultured fibroblasts. Our findings suggest that linkage analysis for severe MTHFR deficiency can be a practical approach for prenatal diagnosis.
