Hirsute Or Hairless? Two Proteins May Spell The Difference
...pes of organogenesis. Since Snail, a protein that impedes
the transcription of a subset of genes, functions in many developmental processes requiring epithelial remodeling, the authors reasoned it might do the same in hair bud formation. Working with developing mouse embryos, they saw a spike in Snail expre...
Newfound roadblock to interferon effectiveness against malignant melanoma
...i-cancer effect of interferon. Interferon normally impedes
the growth of cancer cells, whereas STAT5 is thought to act to promote cellular growth. The new work, published by Professor Schartl and his colleagues in Current Biology, shows that interferon actually activates STAT5 in melanoma cells but that und...
Researchers find molecule that inhibits regrowth of spinal nerve cells
...es and proteins, myelin insulates nerve fibers and impedes
them from having contact with other nerve cells. After a spinal-cord injury, myelin is released into the tissues. Not only does myelin encourage the growth of scars ?called glial scars ?which physically block nerve cells from regrowing in the damaged...
Global warming may have damaged coral reefs forever

the likelihood of recovery. "Unfortunately it may be too late to save many of these reefs but this research shows the importance of countries tackling greenhouse gas emissions and trying to reduce global warming and its effect on some of the world'...
