Application of RLGS to Screening Endogeneously Imprinted Genes, landmark sites. We have named this technique restriction landmark genome scanning using methylation-sensitive endonuclease (RLGS-M), and have used it to screen endogenously imprinted loci/genes [1,2], genes expressing with a developmental stage specificity [3], and cell type specificity [4].

Concluding Remarks,sified as a different type of landmark-visualizing system, based on the new concept that restriction enzyme sites can be used as landmarks, resulting in various characteristic features and advantages.

Principle of RLGS,However, three significant breakthroughs have led to the development of RLGS. First, effective restriction endonuclease for genomic analysis has been discovered. Restriction enzymes which recognize 4- or 6-base pair (bp) sequences, conventionally used produce so many DNA fragments that these fragmen

RLGS Spot Mapping Method,abled us to construct high-density genome map which is essential for position-dependent identification of the gene responsible for a certain phenotype. This approach is so-called positional cloning. In the medical field, the information of the genes identified by position-dependent cloning (includin

When a landmark site was methylated and resistant to digestion, the corresponding RLGS spot disappeared and vice versa. Therefore the

However, the mutation of a single protooncogene or tumor suppressor gene is usually not sufficient to cause neoplastic growth. Tumor progression depends on secondary events

Classically, two hybridization methods, differential and subtractive hybridization, have been used to analyze and isolate such genes [1–3]. However, differential hybridization is effective onl
