Diatom genome reveals key role in biosphere's carbon cycle
...from the surrounding waters. The genome work also shed additional light on how this diatom species uses fats, or lipids, which it is known to store in huge amounts. "Learning the actual pathways they use to metabolize their fats helps explain the ability of diatoms to withstand long periods with little ...Dying cells encourage neighbors to grow
...how normal, healthy tissues are maintained and may shed some light on a pathway that may contribute to tumor growth. It has been known for some time that cells that die as a result of injury-provoked programmed cell death, also known as apoptosis, may stimulate the growth of surrounding cells.

The findings shed light on how the virus caused mass death and suffering, and will help point the way to new diagnostics, vaccines and drugs that would be needed in the event of a smallpox bioterror incident.

..., TGF-beta sends a signal that allows the colon to shed cells weekly as a way of helping to block development of colon cancers. In 1995, Markowitz discovered colon cancers have mutations that inactivate the TGF-beta pathway. "If there is no TGF-beta signal, there is no 15-PGDH.
