DNA/DNA microarrays

By | August 13, 2001

Microbial comparative genomics provides insights into gene function, bacterial speciation and evolutionary relationships. In the August 14 Proceedings of the National Academy of Sciences, Murray et al. describe an approach to explore genome diversity and relatedness in the absence of complete sequence information (Proc Natl Acad Sci USA 2001, 98:9853-9858).They used sequence information from the Shewanella oneidensis strain MR-1 to construct DNA microarrays containing over 100 full-length open r

Sporozoite transcriptome

By | August 9, 2001

The protozoan parasite Plasmodium causes malaria, the most serious parasitic disease in humans. The identification of proteins expressed at the infectious sporozoite stage is important for the selection of potential vaccine candidates. In the August 14 Proceedings of the National Academy of Sciences, Stefan Kappe and colleagues from the New York University School of Medicine describe attempts to characterize the sporozoite transcriptome (Proc Natl Acad Sci USA 2001, 98:9895-9900).They construct

Lipocalin killer

By | August 8, 2001

In the August 3 Science, Laxminarayana Devireddy and colleagues from the University of Massachusetts Medical School report the use of DNA microarrays to identify genes whose expresssion is induced during apoptosis (Science 2001, 293:829-834). They studied cell death of a mouse pro-B lymphocytic cell line upon withdrawl of interleukin-3. The gene that showed the largest induction (12.6-fold) was 24p3, which encodes a lipocalin. Lipocalins are small secreted proteins, and Devireddy et al. found th
