Lively lipids

By | May 21, 2001

In the May 18 Science, Farber et al. report the use of fluorescently quenched phospholipid substrates to screen for genes affecting lipid metabolism in living zebrafish larvae (Science 2001, 292:1385-1388). The lipids were swallowed by the larvae and cleaved by lipases in the intestine before the fluorescent metabolites were transported to the liver and gall bladder. The assay demonstrated lipid metabolism defects in zebrafish mutants that have abnormal digestive organ morphology, as well as the

Prohibitin genotyping as breast cancer indicator

By | May 21, 2001

The 3' untranslated region of the prohibitin gene encodes an RNA molecule that arrests cell proliferation when injected into breast cancer cell lines. A single point mutation in this region creates a variant T allele that lacks the antiproliferative activity of the more common functional C allele. In May 19 Lancet, Eldon Jupe and colleagues from Oklahoma Medical Research Foundation, Oklahoma City present evidence that women carrying the prohibitin T allele have increased susceptibility to breast

Horizontal transfer of tumorigenesis

By | May 17, 2001

Apoptotic bodies are rapidly cleared in the body by phagocytosis. In the May 22 Proceedings of the National Academy of Sciences, Bergsmedh et al. provide evidence that the uptake of apoptotic bodies can deliver oncogenes to the phagocytotic host cell (Proc Natl Acad Sci USA 2001, 98:6407-6411). They could detect the horizontal transfer of H-rasV12 or c-myc oncogenes from dying, transformed rat fibroblast cells to recipient mouse fibroblasts. DNA transfer was detected by PCR analysis and fluoresc
