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

Obesity weighs in as major cancer cause

By | May 17, 2001

Obesity is the single most important cause of cancer among non-smokers, concludes a major review of research carried out over the last 50 years. But the nature of the relationship remains unclear and the benefits of dieting are unknown.In 17 May Nature Julian Peto from the Institute of Cancer Research, Surrey points out that tobacco remains the biggest health risk by far, causing cancer in 60% of smokers. Other causes include alcohol, sunlight and air pollution, each responsible for about 1% of

Corneal healing through apoptosis

By | May 16, 2001

The Arthus type allergic reaction in the cornea is characterised by inflammatory cell infiltration and marked neovascularisation. This gradually disappears during the healing stages through mechanisms that are not yet elucidated but which are essential to preserve vision. In the May British Journal of Ophtalomology, Noriko Ozaki and colleagues from the Nippon Medical School, Tokyo show that regression of the Arthus reaction in the cornea occurs via apoptosis.Ozaki et al injected bovine serum alb
