Several alternatively spliced variants of DNA methyltransferase (DNMT) 3b have been described. Here, we identified new murine Dnmt3b mRNA isoforms and found that mouse embryonic stem (ES) cells expressed only Dnmt3b transcripts that contained exons 1

CpG methylation is mediated by the functions of at least three active DNA methyltransferases (DNMTs). While DNMT1 is thought to perform maintenance methylation, the more recently discovered DNMT3a and DNMT3b enzymes are thought to facilitate de novo

We used mouse embryonic stem (ES) cells with systematic gene knockouts for DNA methyltransferases to delineate the roles of DNA methyltransferase 1 (Dnmt1) and Dnmt3a and -3b in maintaining methylation patterns in the mouse genome. Dnmt1 alone was ab

The 5' region for the endothelin receptor B (EDNRB) gene is a complex CpG island giving rise to four individual transcripts initiating within the island. Here, for the first time, we analyze the relationship between methylation and gene expression in

BACKGROUND Downregulation of genes which negatively control cell cycle progression represents a possible mechanism for prostate tumorigenesis. We examined the expression levels of the p16, p15, p14, and retinoblastoma-susceptibility (RB) genes in pri

DNA methylation is essential for mammalian development, X-chromosome inactivation, and imprinting yet aberrant methylation patterns are one of the most common features of transformed cells. One of the proposed causes for these defects in the methylat

The mechanisms underlying the de novo methylation of CpG islands in human cancer remain almost completely unknown. We used a methylation-sensitive arbitrarily primed polymerase chain reaction (Ms AP-PCR) technique to scan genomic DNA for differential

De novo methylation of CpG islands within the promoters of eukaryotic genes is often associated with their transcriptional repression, yet the methylation of CpG islands located downstream of promoters does not block transcription. We investigated th

DNA methylation in mammals is required for embryonic development, X chromosome inactivation and imprinting. Previous studies have shown that methylation patterns become abnormal in malignant cells and may contribute to tumorigenesis by improper de no

The mouse insulin-like growth factor II gene (Igf 2), located on distal chromosome 7, is parentally imprinted such that the paternal allele is expressed while the maternal allele is transcriptionally silent. We derived a cell line from a mouse embryo
