High-throughput screening for single nucleotide polymorphisms (SNPs) or mutations can be achieved by inexpensive technologies. We modified the original protocols of conformation-sensitive gel electrophoresis (CSGE) to increase throughput several fold to 1.3 samples/min, which is about five times faster than denaturing high-performance liquid chromatography (DHPLC). The modifications include dec...
Reverse genetic techniques will be necessary to take full advantage of the genomic sequence data for Drosophila and other experimental organisms. To develop a method for the targeted recovery of mutations, we combined an EMS chemical mutagenesis regimen with mutation detection by denaturing high performance liquid chromatography (DHPLC). We recovered mutant strains at the high rate of approxima...
Autosomal dominant cerebellar ataxias (ADCAs), genetically classified into spinocerebellar ataxias (SCAs), are a highly heterogeneous group of neurodegenerative disorders. Recently, mutations in the fibroblast growth factor 14 gene (FGF14) have been reported to cause SCA27 subtype. To evaluate the frequency of FGF14 mutations in mainland of China, we performed molecular genetic analysis in 67 u...
Increased expression of epithelial cell-derived neutrophil-activating peptide (ENA-78) has been reported in several immune and inflammatory conditions suggesting its role in inflammatory response. We have identified two single nucleotide polymorphisms in the promoter and exon 2 of the ENA-78 gene by scanning the full length gene using DHPLC DNA fragment analysis and DNA sequencing. The polymorp...
BACKGROUND Matrix metalloproteinases (MMPs) are a group of matrix-degrading proteins implicated in several pathological processes, e.g., invasion and metastasis in malignant diseases such as colorectal cancer (CRC). MATERIALS AND METHODS One hundred and twenty-seven CRC patients and 208 controls were genotyped for MMP-1, -2, -3 and -9 promoter polymorphisms. The genotyping was performed with ...
