Twin survival

By | March 14, 2002

It is generally thought that losses of twin embryos in very early pregnancy are high, with figures that suggest that for every liveborn twin pair a further 10-12 twin pregnancies end up as a singleton birth. But, in March 14 Nature, Stephen Tong and colleagues from Monash University, Victoria, Australia, show that the presence of one embryo does not affect at all the intra uterine development of its twin.Tong et al. used ultrasound to identify and follow-up 48 pregnant women who had double-ovula

Drought resistance gene

By | March 12, 2002

Under drought conditions organisms including nematodes, can enter a state of suspended animation known as anhydrobiosis. This process enables nematodes to survive until rehydration but the precise molecular control mechanisms remain unclear. In March 7 Nature, John Browne and colleagues from National University of Ireland Maynooth, describe a plant desiccation gene that is also found in a nematode.Browne et al. identified a strongly induced 675 base transcript in the anhydrobiotic nematode Aphel

Musical protection

By | March 12, 2002

There has been much debate about whether DNA sequences may, or indeed should, be patented. This issue has prevented the release and dispersal of much genomic data by commercial genomics companies. In the March issue of Nature Biotechnology, Willem Stemmer of Maxygen Inc. in California, offers a harmonious solution for the sharing of DNA sequences while maintaining intellectual property (IP) protection (Nat Biotechnol 2002, 20:217).While the patentability of DNA is in question, music and original

Proteasome inhibitors to treat psoriasis

By | March 12, 2002

Psoriasis is a chronic skin inflammation that may involve bacterial superantigens, but the inflammatory mechanisms and T cell responses remain poorly understood. In March 1 Journal of Clinical Investigation Thomas Zollner and colleagues from JW Goethe University of Frankfurt, Germany, show that proteasome inhibition reduces superantigen-mediated T cell activation and the severity of psoriasis in a SCID-hu model.Zollner et al. used human psoriatic skin tissue engrafted onto mice and observed that

Antisense spuds

By | March 11, 2002

Unmodified starches present a problem to the frozen food industry as they tend to result in poor texture upon cycles of freeze-thawing. In March Nature Biotechnology, Stephen Jobling and colleagues describe a genetic solution to generating freeze-thaw-stable starch (Nat Biotechnol 2002, 20:295-299).Jobling et al. created potato plants with reduced levels of the three starch synthase genes using triple antisense technology. The authors showed that the there was an efficient downregulation of the
