DNA repair of genetic information is an essential defense mechanism, which protects cells against mutation and transformation. The biochemistry of human DNA repair is in its beginning stages. Our research has concentrated on the enzymes involved in the removal of atypical bases from DNA. We present information on the identification and characterization of a(More)
Clinical and experimental evidence shows that prenatal exposure to ethanol causes craniofacial malformations, microcephaly, and abnormal development of the central nervous system. This study describes the effects of ethanol on the development of the principal sensory nucleus of the trigeminal nerve (PSN). The offspring of two groups of rats were examined.(More)
Evidence is presented on two forms of uracil-DNA glycosylase (UDG1 and UDG2) that exist in human cells. We have developed an affinity technique to isolate uracil-DNA glycosylases from HeLa cells. This technique relies on the use of a uracil-DNA glycosylase inhibitor (Ugi) produced by the Bacillus subtilis bacteriophage, PBS2. Affinity-purified preparations(More)
The predicted amino acid sequence of a human cDNA encoding uracil-DNA glycosylase activity shows striking similarity to the cyclin protein family. To characterize the expression of this DNA repair enzyme, we have isolated the corresponding genomic clone. This gene is contained within 4.2 kilobases and is composed of only two exons. Sequence analysis of the(More)
