Arsenic and old telomerase

By | November 26, 2001

Although arsenic is effective in the treatment of acute promyelocytic leukemia it also has carcinogenic side effects, but the exact carcinogenic mechanisms remain unclear. In November Journal of Clinical Investigation Wen-Chien Chou and colleagues from Johns Hopkins University School of Medicine, Baltimore, US show that at clinically relevant doses arsenic inhibits the transcription of the reverse transcriptase subunit of the human telomerase gene (hTERT).Chou et al. found that exposing NB4 leuk

Limited variation

By | November 26, 2001

Small differences in DNA sequence are thought to account for the wide variation between people. In the November 23 Science, Nila Patil and researchers at Perlegen Sciences Inc. in California, suggest that the differences might be less than we had thought (Science 2001, 294:1719-1723).They set out to map a large number of common single nucleotide polymorphisms (SNPs) on human chromosome 21 and to define their haplotype structure. They took a panel of 24 individuals and used a rodent-human somatic

Genomic systems biology

By | November 23, 2001

Identifying genes linked to complex multifactorial diseases presents a formidable challenge for the post-genomic era. In the November 23 issue of Science, Monika Stoll and researchers at the Medical College of Wisconsin in Milwaukee describe a 'physiological profiling' strategy to investigate systems biology (Science 2001, 294:1723-1726).They measured 239 cardiovascular and renal phenotypes, during normal and stressed conditions, in 113 male rats derived from an F2 intercross. They could map 81
